Power supply requirement for ECS KM400-M2 motherboard: 350kw or 400 kw?

Q: Power supply requirement for ECS KM400-M2 motherboard: 350kw or 400 kw?

I am upgrading my pc using my old ATX case with a new motherboard which is ECS KM400-M2. The cpu is AMD XP 2800+. The pc would work for a few minutes or seconds and then just shutdown by itself.

The day before yesterday, I posted this question in this forum and an expert had provided with some suggestions on this problem: It seems that something wrong with the power supply and the cpu temperature. I definitely appreciated that.

Before I throw more money onto this computer (I really don't like to do so), could somebody help me on this issues:

1. Do I need a more powerful power switch? Right now, I have a 350kw power supply and someone suggest me to buy a 400kw one.

2. I actually bought and installed a new case fan. I connect the pins to the motherboard. However, when the pc is starting, from the BIOS, I couldn't see its speed and the temperature. Is that a problem? What's wrong and Why?

Please help!

Thanks very much in advanced!

Samsung 2GB DDR2
WD 320GB/7200/16MB SATA II
Nvidia 8400GS 256MB

Hi,this is for a friend who is interested in buying an AMD A6-3650. The power for the processor is listed as 100w.I want to know what will be the minimum power requirement without any GPU attached.It will be of great help since we wanna cut cost to the most affordable one.

A:AMD A6-3650 power supply requirement

In a standard setup with no-GPU one or two HDDs, one or two ODDs a 300w should be sufficient however I would be hesitant to build any system with less than a 400w and preferably a 500w just because there isn't that much of a price difference and it gives you room for future upgradeability.

For budget PSUs I usually recommend these:
Antec VP-450 = $40 (This is a true budget / low end unit, It is decent for the money but I would recommend the others I listed over it. unless you have a really tight budget)
Antec NEO ECO 400C = $45
Antec NEO ECO 520C = $50
Antec EarthWatts Green EA-430D = $55
FSP Group SAGA+ 500R = $57 (this is good but it is an older model so it doesn't have very many SATA power connectors)
Antec BP550 Plus =$65 (modular if that is important to you)

Almost all of the newer Antecs are made by Delta or Seasonic so they are very good PSUs. Some people recommend the Corsair Builder series in this price range, however the builder series is made by Channel Well Technologies (CWT) which has a less than stellar record and I still don't really trust.

I just came in to the desktop group about 6 months ago, and a few things we do are a little odd (to me). For instance, we order GeForce 9800 cards for AutoCAD users.

But any way, we always ordered these 9800s with a computer that had a power supply that put out lesser wattage than required. So my question is, for the 9800/GTX 260 (nvidia), will it give a message that the wattage is too low or that it is going to start performing less, or can it cause issues without ever giving such messages?

Can it potentially cause issues with other pieces of hardware?

A:Video card power supply requirement (GTX 260, GeForce 9800)

You won't get a warning message.

Most often what happens is a freeze/crash or a restart.

If you haven't experienced any crashes, then the video card is not being stressed very hard. Normally these crashes occur as soon as you put load on to the card, but if this isn't happening, then a 9800 card is total overkill for your application.

You could probably get by with a 9400 or 9500 for these purposes. Technically, a Quadro from nVidia is really their workstation card, but they are all based off the same chips.

Hi all :
I bought a new motherboard today . Its a ECS km400-m2/amd xp2800 cpu.
I need to know how i can use my exsisting hard drive 120 gig without formatting. Im running xp corporate edition on a amd K6-II 500 mhrz/GA-5AX motherboard. If any 1 can help I would appreciate it. thnx

A:I bought a new motherboard ECS km400-m2 /amd xp2800 cpu

while you really should format the drive and perform a clean install, you can install the drive into your new system, boot from the XP CD and choose "repair", this will re-write the OS (with the required files for your new hardware) over the existing installation. That process doesn't always work, but it is your only option if you insist on swapping the drive without formatting

It's been a while since I built a system from scratch and have a... errr... simple question

gfx: Sapphire HD3850 512MB Ultimate (passive)

MB: MSI P35 Neo2 FIR

The motherboard has a power connector for the graphic card next to the slot.

Is there any reason I should connect the power for the card to the power connector on the board instead of directly to the power supply?

A:Graphic card power to power supply or connector on motherboard?

First time I have ever seen that feature. I like it. I'm thinking that is a neat/easy way to partially eliminate cable clutter from the PSU. Give it a shot, you can always revert to PSU cable if you wish.

Hi, I just bought an HP pavilion e9300 a few week ago. And I am going to upgrade the power supply so that I can get a new graphic card--ATI 4870 which requires at least 500 watt power supply. My current computer is shipped with a 350 watt power supply. I will probably get a 650 watt considering the 70% effeciency of power supply.
However, when I talked to an HP technician, he insisted that I could go for a power supply with no more 450 watt. Because the system I just got has a motherboard which has a max power limit 450 watt. He said if I go beyond that, the motherboard will burn out.
So what shall I do? I really want to get ATI 4870 work well on my computer.
Thx very much.

A:Does power supply with higher power rating really burn motherboard?

The long answer is "No".
Just be sure of the dimensions of the power supply before you order a replacement, as HP uses some pretty strange sizes sometimes, and you want the new one to fit with room to spare.

I have a Sony VGC-RB42G computer. I recently moved my computer, cleaned off all the dust, and when I plugged everything back in, it won't power up. The light on the power supply blinks green, inside the motherboard also has a green light that blinks as well. It has a ticking sound too, but I am not sure if it is coming from the power supply or the motherboard. Any idea what could be wrong.

FYI, I have already unplugged everything from the power supply, pulled out the ram, checked the battery, and put everything back together and still no change. One thing I thought was strange was after I unplugged everything, I pulled the power into the power supply again and this time the green light came on but did not blink. It stayed solid.

I was replacing a fan in my case because it made a high pitched sound. I took it out to test it to make sure there wasnt too much pressure from the screws inside the case that were causing this noise. I unplugged one of the molex connectors from my gfx card to test it. It still made the sound so i plugged the molex back into the 2 molex to 6 pin connector and the computer shut off immediatly. Now when i hold down or just push the on button my led flashes and fans spin and stop repeatedly. Any Help would be just the best thing right now.

~Thank you


A:Motherboard or Power supply

NEVER unplug or plug in anything except maybe case fans inside a computer with it powered up! Pull out the video card and see if the computer powers on. If it powers on you have fried the video card. If the computer still doesn't power on, the power supply should be changed before you suspect the motherboard

OK, I'll try to get it right.......

I have an Intel 2.6 Ghz Duo Core on an ASUS Motherboard, 2 Gig RAM and all about six years old running Windows 7 Pro.

When I do a cold bootup from the power OFF condition, the PC freezes at the BIOS message and will sit there forever .....................

If instead I press DELETE on bootup, it will boot right through to the BIOS settings page (blue/white screen) whereupon, I do the ESC and EXIT bit, get presented with "Start Windows Normally" and all is then OK.

If I do a reboot using the reset push button, it will only proceed to the BIOS part where the HARD DISC is checked and again will sit there for ever...........................

Now, to confuse it further, if I turn the PC OFF and ON using the front deck push button, it will do a normal reboot right through to starting Windows correctly.

Whilst the PC runs reasonably well thereafter, it is quite common for it to do a complete and total shutdown for no reason whatsoever or the keyboard or mouse to suddenly stop working.

On the back of the deck is yet another ON/OFF switch and using this to reboot the PC results in a normal bootup.

So something stinks using the RESET Pb on the front of the deck or a normal cold bootup.

I replaced the Motherboard battery, pushed and pulled all the wires - as you do - all to no avail.

It is far from a happy PC and I suspect either the power pack is playing up or the Motherboard is on the way out.

A:Power supply? Motherboard? OS? .... or what?

Sure. Start by going into the bios and checking your temps and voltages; specifically the cpu temp, system temp, 12V, 5V, and 3.3V values. Post those here.

Next download and run memtest This runs from bootable media ie CD, floppy, etc. You need to make the bootable disk and restart with the disk in the drive [CD set as first boot device in the bios]

Test the hard drive with the drive maker's diagnostic. You download this from whomever made the drive ie WD, Seagate, etc. Most of the time you have a choice between a windows version and a dos or boot version; get the boot version. Again it runs from bootable media.

One other thought; have you cleaned the system at all? If not, open the case and give it a good cleaning with a can of air [available at any office store, computer store, even walmart]

Hi! I have a computer (or maybe had) with an Asus M2v-MX SE motherboard with a dual core AMD processor, running XP Pro SP3. Over the last few months. maybe once every week or 2 weeks, it would freeze after booting into the OS. Mouse would freeze and couldn't crl-alt-delete to task manager. I had to unplug it, then reboot and it would be fine. The other day, as it booted the boot message screen came up in different colors within words, then everything had a green hue. The green hue continued after the OS came up. I was just checking mail before I went to work. When I came home, I turned on the computer---and nada. It didn't do anything, and a message appeared on the monitor---no signal. Not even the bios came up. I use the onboard video, so with the green hue I figured Motherboard. But since it sent no signal, now I'm thinking power supply. How can I determine the cause of the problem? I know I can't find a replacement motherboard---it's 7 years old. A month ago, I put in Crucial CT2KIT25664AA667 4gb, but I don't know how this would cause this problem as it hasn't froze since I installed the ram. Any and all responses will be greatly appreciated. Thanks

My pc won't properly boot up (i.e. all the fans turn, but there's no video input), so I have troubleshooted all parts. Eventually I put my PSU in another computer, to find that that one didn't boot at all. I concluded the PSU had to be broken.

As a last test I used a multimeter to manually test the voltages of the 24-pin connector and found that they were all next-to perfect.

Does that indicate that the PSU is healthy, and my motherboard must be dead?

No. It just means that under essentially no load the PSU is delivering the proper voltages. The voltages supplied under load may dip well below what they are supposed to be.

Hello, I need your advice please.

I have a system based on a Epox 8KHA+ with the latest BIOS. 512MB RAM, AMD XP2000+ not overclocked, running at 56 degC., Windows XP fully updated.

The problem is the system keeps turning itself off. After about an hour of running, it suddenly dies as if the power plug had been removed. If I try to restart using the power switch nothing happens. If I then unplug the power lead and replace it, it then starts up OK.

Any ideas please?

Many thanks

i'm sorry if this is in the wrong place to post this fourm

anyways, lately I have been having troubles having my computer bootup and have a startup screen or windows pop up, but it doesn't. I sometimes have to boot it 1 out of 10 times for it to work, and eventually it does. One day it froze, so I held the power button to turn it off, Now it doesnt have a post screen. SO now, the power is on, fans running, videocard fan running, but nothing on display. I'm not too sure if its the power supply, even though its 450watt because it lasted me 4-5 years plus all my fans are running. I posted help and people said it is my power supply due to because it doesn't give enough power to my 8800!

I'm assuming its the motherboard because i heard no beep when I turn on my computer, also I've tried taking my ram out and turning it on and there is no continuous beep i am suppose to hear. I change my ram around, i took out my processer to check, my monitor should be fine. When I turn it on, the only sound i hear from it is my discdrive , and also my cpu fan is the last fan that spins after awhile.

My computer recently had a failed fan in the power supply unit. I took the machine to an official computer tech company and they replaced it. I brought the machine home, used it once. I turned off the machine, unplugged it to use outlet for another computer.

I then replugged in the machine with the new power supply and nothing happened when i turned on the machine. Nothing, nada, zilch. No noise, no video, no nada. I see a green light on the chip board inside the unit so i know its receiving power, but no Action.

Is this my motherboard now, and maybe my processor. The tech's say that i need a new motherboard and processor. But i dont trust them anymore after my replaced power supply and now dead computer.

Any suggestions on the logic of what's happening with my machine? PLEASE HELP. I'm an end-user, not a tech...so I just need this all to make sense.

Thank you!

A:Power Supply or Motherboard?

Hello there and welcome to Techspot!

I feel your pain. We've all been there. Not that sympathy makes things any better, but you have mine.

It is hard for us to tell what is wrong with your system without looking at it of course. But maybe we can help you confirm a few things.

You say you can see the green LED light is lit up on your motherboard. That's a good thing. When you push the power button, no fans are spinning at all? Not a good thing.

It could be any number of things, and the tests that need to be done involve removing parts to help troubleshoot. Do you feel comfortable doing these types of things?

Try unplugging and reconnect your power supply connections to the motherboard.

I would also test your computer case's power-on button. This is done by disconnecting the small 2pin cable from your case that goes to your motherboard, then using a screwdriver to quickly touch the two pins that that cable was connecting to. This will short the pins, and hopefully start your computer. If it does, then your power switch on your case needs replacing.

Other than that, I would try this test to see if you can get the power supply fans spinning: http://modtown.co.uk/mt/article2.php?id=psumod

If the fans on the PSU don't spin, then you have (another) dead power supply.

If the fans on the PSU do spin, then we have narrowed you down to either a dead motherboard or a dead CPU (probably motherboard)

Case #1:

Heres the thing, I went to a friends house (wolvman on here) and was getting it set up. He told me that because I needed a hard drive still, and that neither of the raptors he gave me worked, he had a 160 gig IDE drive. I plug it up, having to unplug the side fan, because all of the power supplies I have are limited to 6 ( I think ) legacy connections.

I start the computer up, nothings wrong, but its lagging a little due to the system (XP home) getting drivers, etc. for the hard drive. It comes up and says its working, so I check it, and it was. It had a previous installation of XP on it, so I see everything. We then decided to play CS:S, and about 10 minutes into it (it was running fine and dandy) it just shuts off. First I think that the GPU went out, because I didn't notice the computer went off, just that the monitor said "No signal", but it went completely off.

I proceed to try to turn it back on, and it does NOTHING. I pulled the side of the case, and checked how hot it was. The Power Supply was pretty freaking hot, along with the GPU, CPU, and HDD's. This is where I get scared. First, I think it just overheated and shut down, but then I realise that that's usually a BSOD, correct? Would the HDD's usually get that hot? Its a simple Maxtor 160gig, I believe its 7200 RPM.

No point in making 2 threads. X_D

Case #2:

I got a motherboard from him after this, us deciding that I needed to upgrade anyway.... Read more

A:Either Power Supply Or Motherboard went out

Maxtors fail way too frequently. Next choice is the power supply. Watch from the back with a strong light when the <ON> button is pressed. Does the fan blade turn four revolutions or less. That is a bad power supply.
There is no relationship, really, between heat and a BSOD. It can just as easily shut down as give you a BSOD.
I'm betting it is power supply, memory module, or Maxtor failure.

Hi, I'm on a mission to patch together some kid's emachines T2682 P4 pc. I'm pretty sure the motherboard is toast, I managed to get it running once, began a defrag, then the screen went to "no signal" (I could hear it was still running) and on reboot, no beeps, no post, no signal. The fans run, so I think the power supply is ok. I removed the ram, still no beeps, no video signal. I'm set to order another board, but I read where in most cases the power supply is what causes the mboard failure. Should I get a power supply and try that first? Is there a way to just check the ps?

I would replace the power supply at the same time as the mother board. I had a faulty supply that seemed to work, on an Emachine that was under warranty. It blew the motherboard and keyboard and a wirless adapter that was pluged into the usb port at the time. they replaced all the parts but the wireless adapter because that was my own part. They put in a used power supply and just after the warranty it went out again an took the motherboard with it again. I took out the harddrive and threw the rest in the garbage. No more emachines for me. It was cheap and used as a second computer for the grandkids so no loss.

I am working on my aunts PC (HP slimline), again! This time it will not turn on, seems relatively easy problem. I press a power button and exactly nothing happens, not even PSU fan spins. I do not have a tester for FLEX PSU (they have that tiny 24pins and not regular size ones), but I take it out and cross the green wire (PSU on) with black ground wire and the PSU turns on, hmmm. So I independently test out each voltage on all wires and they all come out with proper voltages.

I put the PSU back in and I test out the power button and its wires, and they are fine. I even crossed the pins on the motherboard to get it to turn on and nothing.

The thing I can not get my head around it that in every motherboard failure I was a witness to, I was at least getting some PSU response (fan spinning). That is why at first I thought it was PSU for sure, but I do not have spare FLEX ATX PSU as they are not common at all.

Would I be wrong to assume that motherboard went south? The way I see it, ifI get a new motherboard (for a lot less than new FLEX PSU) with standard power supply plug I can just put the PC into normal chassis (I have spares) and use one on my many spare ATX PSU's and eliminate both possible sources of error weather it is a motherboard or FLEX PSU.

Thoughts? Thanks...

Power Up computer at 3:20

While I'm walking away I think I hear a rather remarkably loud beep, or maybe two beeps. Either way when I come back to my computer it's powered on however, the monitor shows "No SIGNAL"
I go through the standard, try the monitor on another computer, check the cables etc.
After a few more tweaks I power the computer up. Still no signal. Another power up later I notice there is no POST beep.
I check everything and try again. No post. I reset CMOS, no post. I notice at this moment that the VIA chip fan isn't spinning.
I unplug all peripherials and try again no POST the computer comes on for a brief second then everything stops, the PSU fans, computer fans everything.
Now that's all I get it's like the car starts but doesn't turn over.

I'm assuming this is either a powersupply problem or a mother board problem. How do I narrow it down? My MAJOR concern is I have 2 segate drives RAID ed (the one for speed, 1 I think) if I get a new mother board I need to keep this info is that possible? So I guess in order of priority here are my questions...

1)How do I get my data off my Raid drives?
2)Is this a PSU issue? Or a Motherboard issue?

Recently I had a problem with my computer where the monitor would not get a signal no matter what and I also tried another monitor and got the same problem. I took out everything other than the motherboard, CPU and RAM. The computer started working so I put everything back in one by one and tested them each individually and it all worked until I put the graphics card back in (GeForce 8800 GTX). Now every time I take the card out of the computer it boots fine and the monitor works, but when I have the card installed the monitor gets no signal, even though it is connected to the motherboards VGA port and not the graphics card. I replaced the GeForce 8800 GTX with an older GeForce 7300 GS and it had the same problem, so now it's happened with two graphics cards even though the monitor was not connected to either of them (I'm hoping this is a sign that my 8800 GTX is not the problem?). When I originally started having the problem and took out the graphics card this problem was still happening, so I have seen it happen both with the video card installed and with the video card out of the computer, but now the computer only works while the card is not installed. I have had people tell me that the motherboard was probably failing, but now the motherboard appears to be working fine...as long as no graphics card is installed (they are both PCI-Express so maybe that slot is is having problems?).

I recently decided to upgrade my computer big time by purchasing a new motherboard and processor and power supply/case. Anywho, it is a KD7-E motherboard, an AMD Athlon XP processor, and a 300watt power supply. The processor doesn't seem to be the problem though, so that shouldn't be anything to worry about. I put the new MB in to the case and hooked it all up correctly. I triple checked it a million times. It simply would not turn on at all until I hooked a friends power supply in to it, and that seemed to sort of jump start it. It came on, the fans and the lights, and it would seem to go just fine but then it would sort of hiccup and die. We hooked my power supply back in to it and it started working, but hiccuping just like the other. It would start up, fans and all, then they would just die all of a sudden. It seems that it runs longer though if you hold down the power button, for some reason. At first I just thought the power supply or the motherboard was fried, but that cannot be it, since they both work...just not well. I think it might be a short in the motherboard maybe? And it is not a lack of power either. It is a 300 watt power supply and that would be enough I believe. That, and my friends who we hooked in to it was a 450watt power supply, and that is more then enough. Anywho...dunno if anyone has heard of anything like this before, or have any suggestions or tips, but I would really appreciate it. I'd like to get it working instead of having to se... Read more

A:Motherboard/Power Supply problem

Read other 6 answers

Hey guys,

My motherboard has recently blown and I've had to replace it. My only issue is that it has a different internal power source to my former motherboard and I'm not sure if I can utilise my old power supply with it. I've included pictures of the motherboard connection (the blue one) and the power supply connection. Power supply connection is for a larger connection but it works perfectly with the motherboard, except it is inserted into 4 slots rather than 8.

Is this safe? It seems to be working fine.

Just in case, these are my specs for a New self-built( for the first time) machine.

MB: ASUS P4P800-E DELUXE ATX Intel Motherboard
CPU: intel Pentium 4 3.0E 800MHz FSB Socket 478
HDD: Seagate Barracuda ST3120026A 7200 RPM IDE Ultra ATA100 Hard Drive
ASUS N6600/TD/256 Geforce 6600 256MB 128-bit DDR AGP 4X/8X Video Card
2GB RAM(4*512MB)
Aspire ATX AS 500w PSU(came with the case)

When I got finished with hooking everying up in the case, I turned on the power and guess what? It turned on for split second and then died down. I tried doing it again and again(for like what seemed like 50 times which... might of caused a future problem...) with different things unplugged and it still always did that. After all that I figured that the problem can be at least somewhat cured if I take out the big 20pin plug and put it straight back in and then it'll fully power up. But sometimes for some reason it goes straight back to powering for a split second and dieing. As long as I disconnect and connect the big power cord it'll power up, but that's not the problem I'm having NOW.

When I DID get it working I'm sure you can imagine my joy that I finaly got it to work. So I went straight to installing Windows XP and then something happened. The computer friggin froze. Restarted and in the middle of the installation it froze again. Repeat like 2 more times and then I've finally got XP installed. Only thing is is that it, of course, it froze most t... Read more

I am working with a friends Emachine T2042 2ghz Celeron. She told me that the machine wouldn't turn on - no lights, POST, etc. I replaced the PSU and am having some problems. Once I connect everything, only the PSU fan and the fan cooling the CPU are operative. No HD lights, POST, etc.

I've checked the 20 pin connection to the MOBO. It seems to be seated correctly. Any other ideas?


A:Power Supply - Motherboard problems

Hate to sound brash, but you're yet another person with a bad emachine. The bad news is emachines are notorious for horrible quality computers. This problem is posted ALL the time. The components and construction in emachines are of the cheapest quality. Their PSUs often blow out - often taking the motherboard along with it. If the computer is still under warranty, send it in. If not, test the PSU. You might be able to replace the PSU - however don't be surprised if the motherboard is also fried. If not- you're lucky. If it is toast , you might be able to salvage components and/or data by building another computer yourself.
You can buy a PSU tester for $12 at circuit city.

To all others: AVOID emachines period!

the ASUS A7n8x-x motherboard , I was told was compatible for my system. My question is , when I looked it up on newegg.com, there were two....there is a ASUS A7n8x-x going for @ 74.99 and also a ASUS deluxe for about 118.99 , they both have nvidia nforce2 utra 400 + Mcp, is there a big difference between the two as far as perfomance? I also saw a ASUS A7v8x-x with a VIA chipset ( my comp ran a VIA before) and I just wanted to make sure that I can run a nvidia chipset.
Also.... I looked into my power supply and it's a 250 W max. I am not sure what wattage max I can ,or should go to . Any help would be great. thanx

A:motherboard and power supply questions

I recently bought a new computer from Dell and a new graphics card from newegg. The computer is a Dell Inspiron 545 and my graphics card is a Nvidia Geforce 9800 GT. The graphics card requires a minimum of a 400 watt PSU which unfortunately Dell only gave me a 300 watt PSU. So I replaced the 300 watt PSU with a 460 watt PSU that I purchased from a store near my place, but when my computer is shut off, the motherboard would make static noises. The noises sound like a cross between clicking/static that appear around 5 minutes after my computer has been shut down and start to fade away after an hour. The noises would only go away if I switched off the power on my PSU. I replaced the new PSU with my old PSU and the static noises went away.

The power supply that I purchased was this:

I called Dell about my problem and they said that the motherboard could not handle a power supply of more than 300 watts. I bought the computer and graphics card online so it would be a real pain to return and I'm not really fond of replacing my motherboard.

I was wondering how I would be able to get rid of the static noise.

A:Motherboard and Power Supply Issue

Dell lied to you, the motherboard has no idea on the wattage of the power supply, it simply draws as much as it needs. That said Dell's are cheap systems.

The power supply you got isn't of the best quality, and it may also be faulty. Return it for a higher quality brand and see if that resolves your problem.

I currently have a dell E310 dimension w/ a 230 w power supply
i want to upgrade to a ATI Readon 9250 PCI video card which requires more power
I have a Thermaltake Purepower 420w power supply which has a 20 pin connector--the motherboard has a 24 pin socket. there is also a 4 pin plug from the power supply . will the computer work with the 20 pin connector or do i need all 24 connections? --is the 4 pin connector supposed to make up for the extra connections?

A:20 pin power supply to dell 24 pin motherboard

Should work fine with the 20 pin, but there is another spot on your board for the other 4pin

the power supply should have 2 cables, the 20pin(or 24pin) and another cable with 4pin, both of those go in differnet spots,

and from what i know it shouldnt be a problem with the 20pin going in the 24pin.

Wait for more people to reply i might be wrong

I've been having issues with my (old) gaming PC and I would like to either replace or upgrade the components but I'm not sure what the issue is.

Here's a list of what happened:

- 1-2 years ago I was experiencing BSODs on PC boot so I decided to check each ram individually to see if one of them its causing the problem. So I found that 2 sticks were faulty, so I removed them and I was left with 4GB ram.
- 2 months ago, I tried to turn on the PC and it was shutting down after 2 seconds, or it wouldn't even start at all ( no signs of power)
- So I decided to disassemble everything and clean my dusty fans(there was a lot of dust inside the power supply) and tried to boot again. This time the PC was booting but with no display.
- So I removed everything expect the CPU, Cooler and fans and tried to boot again. Still no display, no beeps and fans were spinning.

Is it safe to assume that my motherboard is bad? Is there any other way to test it to make sure? Because if it's the motherboard I might be replacing the whole system, unless its the power supply that's faulty so I could replace it with a cheap one at the moment and upgrade the PC later.


OS: Windows 7 64 bit
CPU: AMD Phenom(tm) II X4 555 Processor
Motherboard: ASUS M4A785TD-V EVO
Memory: 4GB (DDR3 SDRAM)

or the video card? The CPU i want to buy has 35W, do i have to look up if my motherboard or power supply or video card supports that?

A:Does the CPU's W have to match the power supply or the motherboard?

When looking at a new CPU's compatibility to a system, check whether:-

1) Your CPU supports the socket that your motherboad has.

2) Your motherboard's BIOS supports your CPU, if it doesn't, check the manufacturer's website for updates that'll allow support.

3) Your current cooling setup (Heat sink and fan) supports the new CPU.

4) Your Power Supply Unit (PSU) is powerful enough to handle the CPU. This is what you meant in your above.

Fill up your current system specs and tell us which CPU it is you intend to upgrade to so that we can advise you further.

Hi, my 480W (don't know the brand) power supply gave out a few weeks ago so I replaced it with a 430W Thermaltake. Ever since then, my motherboard (AsRock P4V88) has been 'starting up' slowly. Normally, it detects the Primary and Secondary IDE devices within a few seconds and moves on to boot windows, but now it takes about a minute to get through it. Also, it sometimes stops at the 'Initializing USB controller....' and it'll never complete. I don't think it freezes at that point, because if I press F2 or F11, and it'll tell me that it's preparing to enter setup/boot menus. I more or less solved the problem by powering down the computer for about 5-10 minutes, and it got past the USB issue fine, but it still took a while to detect the IDE devices. I think it's time for a new motherboard, but I'm hoping to salvage it.

I made a thread this summer regarding problems charging my iPod. I had been assuming it was an issue with my motherboard, but recently began thinking that it could very well be my power supply. I was just wondering which is more likely, and if there's a simple test I could do. I'd easily be able to get my hands on a DMM.

This is the thread from this summer:

A:Motherboard or power supply problem?

Only thing I can think of is to test the PSU in a different computer - or better still, put a known working one in your PC. Seems strange that the iPod not charging is the only symptom of either however.

I replaced a motherboard, processor and memory. All should work with each other. I got everything connected and cannot get the power button to work. I have tried it every different combination that I possibly can. The led on the mb is on. Any suggestions? I can't even get it to do anything. This computer worked until I took out the old parts and replaced them wiht new. Is it possible the MB is bad?

A:problem with power supply and motherboard

Yes, the board could be bad; but, more testing is in line before deciding that.

Are you certain you have the power-on switch connected to the proper pins on the board? Thoroughly checking this is a must. Study it carefully.

Is it possible you have the CMOS-clear jumper set to 'clear'? I have bought boards that had this setting out of the box. I never could figure why they would do that; but, they did.

Are you certain the processor is fully seated into its socket? And, are you certain there are no bent pins?

If you have checked all of the above and found nothing amiss, disconnect everything from the board and remove all add-in cards and see if it will power up.

Alright, well I'm looking at purchasing this motherboard here:


If you'll look at a couple of the reviews, they mention this:

I neglected to get a 20+4 pin power supply for I dont know what reason, but once I had that everything worked. If you have a GPU which 256MB dedicated RAM or above it is reccomended that you get at least 14 amps on the 12 volt rail.Click to expand...

I have a 256MB GPU. My question is, what does that guy mean by the 14 amps/12 volts/20+4 pin power supply, and what do I need to get one? The case I'm looking at buying is this:

Does that include enough power, or should I be looking at another power supply in addition? Thanks in advance for the help.

A:Motherboard Power Supply Question

I'd recommend taking out the power supply that comes with that case and getting yourself a reliable one. Powmax are not really PSU makers, they are case makers (who include PSUs with their cases). In other words their PSUs are made with very cheap parts. You do not want a cheap psu. Read through this forum and you will see many people with really hard to diagnose problems that most of the time are the result of going cheap on the PSU.

To answer your questions briefly:

PSUs put out different types of power, as different parts on you computer like different flavors of power. There is 12v power for some parts, 5v power for others and 3.3v for the rest. A cheap PSU is not very good at making these different types of power, specifically the 12 type. A good PSU should be putting out at least 24amps as a minimum.

And the other question, your motherboard uses a 20pin connection from the PSU. Most new PSUs are a 24pin connection, but a lot of them have adapters that come with them, or better yet, the 24pin connector actually allows you to "snap" off 4 of the pins to change it to a 20pin connector.

I'd recommend getting a PSU from a company like enermax, fortron or Antec. Have a look at this thread for some great info:

I have a power supply of ATX 12V V1.3 and my motherboard has a label says "24-pin ATX V2.2 Power Supply." Are these two components capable? Will there be any kind of problems that might occur such as pc shuts off itself and automatically restarts?

A:incapable power supply with the motherboard


Are you sure you don't mean "compatible"? If the PSU has a 24 pin plug for the main connection to the board, then it is. Earlier PSUs have a 20 pin plug for the mother board. some PSUs have something called a "20 plus 4 connector" which will work for both new and old motherboards. Since there is only 1 plug (the main board connector) coming out of the PSU with anywhere near that many pins, simply count 'em. 2 rows of 10, no worky, 2 rows of 12 in like Flynn.
