Is 450W power supply sufficient for the following ?
Intel Dragontail Peak DP35DPM motherboard
Intel Core 2 Duo E6750 2.66 Mhz
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 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!

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

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.

If the CPU is overheating (or failed), the system may be shutting down in self-protection. Have you been overclocking? Have you reset the motherboard settings to default?

My first post...

I received my new DVD DL +/-RW drive today and eagerly installed it. I of course unplugged my computer's power supply while doing it. After plugging the power back in, the green LED on the back of the CPU started blinking (never noticed this before), and when I hit the power button, NOTHING happen. No fan turns, no lights, nothing. When I unplug the power supply, the green LED blinking gets slower and slower, and after about 15 minutes it totally stops. I plug the power suppply back in and it starts blinking all over again and still the power won't turn on.

All I did was replace a CD-ROM drive with a DVD Multi drive. I didn't mess with anything else, so there should be no power supply shortage or problem. Any thoughts as to what could be happening?

By the way, I have a 2 year old Compaq computer with 2.0 ghz Athlon 64, 1 gig RAM, no problems thus far.

A:Computer won't power up after disconnecting power supply

While installing the new optical drive, you might have inadvertently loosened one or more connectors. Recheck all data and power cables to make sure they are tight, including all those to the motherboard.

I'm currently a computing student so I rely on my computer a lot for my studies and was hoping I could get some quick advice/troubleshooting on here. So here goes :

I've had a problem with my computer recently, it's been working fine for a year or so with no problems, and then one day i tried switching it on and nothing happened. I tried once more and then the power short circuited (I then had to turn the power back on from the mains switch).

The strange thing is, my housemate had exactly the same problem, and after searching for the answer , he was told it was due to a static buildup and the solution was to take out components (graphics card, RAM) e.t.c and put them back in.

I tried this and no luck , I was thinking due to the short circuit, there may be a problem with a fuse in the power supply? other then that I'm completely stumped and would appreciate any help given.

Many Thanks for all help received

A:Computer won't power up (poss. power supply)

Does it happen with any other appliances? as in does using the toaster while using the kettle While your mate is in the Electric shower, telly on, or ironing?

Possibly a static build up, it is possible, Wher are you situated??
What voltage are you on?

What is the make and model of your comp? is it the same as your friends?

is your machine custom built or is it a brand?
Answer a few of them and we will try to narrow it down 4 you..

Mean while if you could get your hands on a spare PSU that would be handy. And remember when dealing with PSU's alway leave them to sischarge for at least 24hrs,

Hi everybody,

For the last several days, I've been doing a lot of research about whether my power supply can support my graphics card, but I can't seem to find a definate answer. What I have is a 450 watt power supply; it has one single 12v rail that provides 24 amps. My graphics card is a ATI Radeon X1950 Pro PCI-E. It requires a 450 watt power supply and recommends 30 amps on the 12v rail.

When I asked whether my PSU can support my graphics card on other forums, some people tell me it can, but others tell me it can't, so I'm really confused right now. I had my X1950 hooked up and running for 3 days without having any problem, but I took it out today, just to be safe until I can get a definate answer. Although I do notice that my power supply runs cooler without the X1950 hooked up.

But on other forums, I even heard people run this card on a 18 amp 12v rail without any problem and they even have it running on a fully loaded system with 2x HDD, 2x DVD Drive, cooling system, fans and lights. And many people say that 22 amps should be the minimum to this card and 24 amps should be fine. However, there are also people who say that you should follow the manufacturers recommendation and get a minimum 30 amps power supply.

To give you a better idea of my system, here are the specs.
Pentium 4 HT 524 Prescott 3.06 GHZ (84 watt)
Motherboard: ATI RC410 ULI M1573
2 stick of DDR2 Ram 1x 1GB and 1x 512MB

I have 2 failed Z800 power supplies (1150 watt version). After some internet research I am led to believe this is a common problem and related to the PS capacitors. Since I do not know how to do this capacitor replacement (yet). I thought I would buy a new PS. However, I do not want to buy a Z800 PS since it seems to me to be a defective design. Can anyone chime in and tell me if the new z840 1125 watt PS will work with my older z800? I have called HP support and spoken with the correct support people on this and they were not able to confirm if the Z840 PS will work (fit) on the z800. The closest confirmantion I recieved was that if it fits then it should work. Instructions to fix the capacitors:http://h30434.www3.hp.com/t5/Business-PCs-Workstations-and-Point-of-Sale-Systems/Z800-power-on-issue... Same issue I am facing:https://www.youtube.com/watch?v=f563JGeoxaw On a side note, can anyone recommend a good service tech to make such capacitor repares in Southern California or insrtuctions on how to make this repair (with pictures). Thanks

Power supply problems relate mainly to video graphics. I suggest you get a quality power supply from the list of power supplies on this forum you can find with a search. Certainly 400 or 500 watts is a good choice, if it has steady output.

It'll depend on how much other hardware is in that system, but there is a good chance it will work. No way to be certain until you pop it in, but my guess is, you'll be good.

I'm trying to figure out how many amps at 12v the system I'm building will require, since it seems like the true limit of basically any PSU is the amount of power is supplies on 12v rails. I have a PSU that supplies 17A at 12v and I'm hoping that will be enough. The system is pretty basic:

ASUS M3N78-EM mobo with NVIDIA GeForce 8300 onboard video
AMD Athlon 64 X2 5400+ Brisbane 2.8GHz 65W processor
1 SATA DVD-ROM drive
May add one or two IDE or SATA HDs and a TV tuner card down the road

I'm having trouble finding data on how much these devices will draw from the 12v specifically. The CPU isn't hard, since it draws all its power at 12v: 65W/12v = 5.4A. Let's say 6.5A with imperfect efficiency, though I have no idea at what efficiency I should expect the CPU to operate. But what about the rest? In particular, I expect the onboard video to draw significant power at 12v, but I can't find how much.

Can anyone help? And can anyone suggest a resource for finding this kind of information in the future? When I find power usage information at all, it's usually simply listed in watts, without specifying which rail it's drawn from.

I did find the following two links in thread:


Both seem pretty useful (if a little out of date), but neither site seems to have good information on onboard video.

A:Please help me calculate power requirement

The onboard graphics doesn't draw significant amounts of power. You could say 1-2 A on the 12 V rail. It's quite a lot less than what a better discrete graphics card, let's say Radeon 4350 would draw.
What's the actual model of your power supply? If it's a "Ultra value 500w power supply" then even the underpowered 17 A @ 12V isn't most probably true, rather it's measured as a top peak output at unrealistic circumstances, for example a lot lower ambient temp than what it normally operates at.

Computer: ACER Notebook
System: XP

Computer has traveled the world, not been treated either too good nor too bad, mostly traveled in a notebook carrier, occasionally in a backpack.
the battery is long worn out, computer needs to be plugged in.

the problem is definitely not the power supply (brick).

There is some kind of short in the system so that even if the computer is turned off, attempting to plug in the power supply results in it turning itself off in self defense. If one unplugs the supply from the wall outlet, it recovers itself (it can be used to power my other notebook).

The computer didn't emit any smoke or burning smells, but obviously doesn't want to turn on at present.

I've already partly disassembled the unit and didn't find anything looking bad, but I can't get right at the plug in point yet.

I am not in danger of losing data, it's just that the notebook was a nice little performer and handy at internet cafes.

Any ideas or tests you can think of?

A:Computer shorts out Power Supply

Why would you want to use a desktop power supply to attempt to power a laptop? Completely different applications and even though you would be using 12v DC you could still damage the laptop...or worse. The power good line is for the power supply to receive a signal from the motherboard that it is getting all the power signals.

I am about to buy a new computer. I am really into video making/editing, and need one that can handle alot of rendering, as well as run Adobe After Effects and such cleanly. I also want a Blu-ray player. So far after building a couple computers from hp.com, dell.com, alienware, etc. I've found I can get the memory and other features I want cheapest from Dell.

Here's a list of the one I built:
Intel Core 2 Quad processor Q9550 (12MB L2, 2.83 GHz)
Vista Ultimate 64 bit
24" Full HD Flat panel monitor
8GB Dual Channel DDR2 SDRAM at 800MHz - 4DIMMs
750 GB Serial ATA HD (7200 RPM) w/ Databurst cache
Blu-ray burner
ATI Radeon HD 3450 256 MB supporting HDMI
7.1 Channel Audio
Wireless Keyboard/Mouse

That will cost right at $2,019 which is alot less than a comprable Alienware or XPS. The only problem I really have with this one is the video card which I looked into replacing but this computer only has a 350W power supply and most video cards that are worth anything need at least 400/450W, plus i'm not even sure if I could buy one that would fit in this computer.

So should I get this and get another power supply? Can that even be done? I also looked into building one of my own but i've never done that before and am not sure how to go about it. I looked up a bunch of parts on newegg.com but they all looked the same to me and I would be afraid I would buy something that wasn't compatible etc. plus some of the motherboards said they couldn't support ...

Something wierd going on, I can shut my windows XP down like normal, and I get all the way thru the shut down screens, the LCD screen goes blank, the keyboard lights go off, but the power supply in the computer remains on, powering the fans and lighting up my front panel fan control Assy. In order to turn off the power supply, I need to switch the switch on the back of the computer (power supply switch). Then, to turn if back on, I need to turn on my Power Supply switch, and open the case, and lightly touch/push the area near the CMOS battery, and without even touching the front panel power switch, the computer comes to life and I am able to load Windows XP and go about my bidness as normal! I SUSPECT this was caused from a lightning storm a few nights ago, it wasn't near me, but it caused the power to go out and come back on rapidly like three times. What gives?

I just wanted to see if someone could confirm what I think is wrong with a computer. I had computer shipped to me from a friend. When the computer arrived the CPU fan was dangling from its wire. At first I did not notice any other damage. I tried to power it up after I reseated all the components. The computer acted like it would start and then it immediately shut down and tried the power button again it was dead. Instantly I though power supply I had a brand new one in my spare stuff that fit the requirements of the motherboard. After installing new power supply the same thing happened. It will try the first time you hit power (the fans will run etc) but then it shuts down straight away. I stripped the unit down to the bare essentials just one memory chip, CPU and CPU fan. The unit will not power up. I look at the motherboard closer. I do not see any burnt spots but I did notice one of the capacitors slightly bent over. This leads me to believe that the mother board maybe damaged and the cause for failure. If someone else with more experience than me would like to confirm that or give me another direction to go I would appreciate it. Thank You

How can I find out if it's an ATX power supply?

A:Computer desktop power supply

An AT PSU has two motherboard connectors and a separate power cable with a switch.

Mind you, not being an AT, the PSU can still be any of the proprietary or small form factor PSU standards.

You should look up the ATX pinout and dimensions on the internet and compare with your PSU.

The thing is worth only petty money. It is too weak to power any modern hardware so it could be used only as a spare for an old machine or for a low-power project.

A:Computer power supply question

That's an absolutely horrendous PSU, return it and get a decent Antec/Corsair/XFX unit. It should tell you something that a PSU apparently rated at 650W only has one PCI-E connector, I.e. it's bad quality and won't output anywhere near 650W.

Out of interest what GPU do you have?

Hi... I need to know,in short,how the computer power supply works.My concern is based on the (50's) Ac powered wall clocks,would vary in their accuracy due to the 60 cycle rate from the power company,not being dead on the 60 cycle scheme..They usualy were a bit higher.
I understand all that... Today the Hz / cycle rate from the power company is still a bit high / fast...
With that in mind,I'm getting to the question:With the power supplys used today in computers is it possible ...due to the AC input cycle flucuation,for the computer clock to be running slightly fast..?? It was argued that,the comp clock shouldn't be running fast.A search on the internet,will show that this is a common occurance...
I just figured that it may be from the AC input source,that could cause,the timing to flucuate,and hence cause the system clock to also flucuate...While not harming anything within the comp with it's daily functions,it could however have an effect on the system clock,and it's accuracy.....
I ask this due to me getting into the field of watch collecting.Most movements being Swiss mechanical... In checking for accuracy of the movement,I've discovered that I'd have to use some sort of Atomic Time refferance...via the internet,because my system clock consistantly,runs about 5 secs fast daily,24 hrs.This is where the argument came in.It seems some judge their movement accuracy via their system clock.I mentioned that that wasn't a good idea,becaus...

The PC clock is battery powerd so will not be affected by the wall outlets AC (Howd you think it keeps the time when you turn it off?) lol

Hey everyone
Okay my problems kind of long and complicated.

First off, my computer had this problem where it wouldn't turn on, pressing the power button did nothing. So I started turning off my power supply and unplugging it to give it a rest, and it started working again when I tried turning it on after unplugging it for a while. Now everytime I turn off my computer I need to turn off the power supply and unplug it.

But now when I'm using my computer, it freezes a lot. Like the whole thing freezes and I have to reset it. sometimes it goes a long time without freezing.

The weird thing is it DOES NOT freeze as much when I'm playing a video game, it DOES freeze a lot when I'm on msn or IE. BUT it also does freeze when I use other things even video games but not as much. I don't know what it is. I've tried anti virus but I can neve rcompltete without it rfeezing. I have no clue what to do.

A:Computer keeps Freezing - Power Supply?

its either power supply or heat related. you can buy an inexpensive power supply tester for about 20 dollars at different sites... that will tell you if that is the culprit. If that is not it I would say its too much heat as that will cause freezing at intermittent times. You can download temp monitor programs and monitor your southbridge and cpu temps to know if thats your problem.

Sorry if this is very similar to other posts. I have done my research and I believe my problem is due to a bad power supply, but I just want to confirm since the one I bought is known for being very reliable.

I built my first computer about a year and a half ago, running Windows 7. Lately my computer has been freezing about once per day, with everything remaining on the screen and my mouse locked in place. The computer becomes completely unresponsive (mouse, keyboard, DVD drive, etc) until I cut the power and reboot. I have also noticed that either a fan or the hard drive spins quite rapidly when this occurs. I did not have this problem when I first built the computer, and from what I can tell the crashes have been more frequent in the last few months.

I originally thought it might be my hard drive, so I ran chkdsk /f and did not find any issues. My reliability history does not show any patterns suggesting that software is the issue. My event viewer, however, shows 40+ critical errors from Kernel-Power saying that "The system rebooted without cleanly shutting down first. This error could be caused if the system stopped responding, crashed, or lost power unexpectedly."

Following advice from other posts I checked my voltages and temperatures. Here are the results from CPUID Hardware Monitor. The most glaring problem is unusual results for the +12V and -5V voltage readings. I am not sure what to make of it since my bios shows +12.302V for my +12V re... Read more

A:Computer freezes due to bad power supply?

Update - I took a multimeter to the power supply pins as discussed in this post:

Here are the voltage results:
+3.3V +3.39V
+5V +5.15V
+12V +12.18V
-5V Missing because apparently -5V is not used anymore
-12 -12.27 V

All continuity PSU connections were correct except for the orange +3.3V connections. They were reading 30-35 ohms. According to the guide any wires less than 50 ohms are potential problems.

I did not check the motherboard for continuity because I did not want to remove the CPU yet (are there alternative ways to test the motherboard?)

Hi everyone...I just received my new computer. Unfortunately I think they forgot to put in the power cable. So my question is, can I just use the same cable from another PC? Or are the cables specific to the power supplies? Thanks in advance.

A:Can I use same power supply cable on another computer?

I have been using the same power cable for about the last 4-5 computers.

I also really should put a newer one on someday. Use your old one. LOL

Well, my motherboard on my old computer died and it was old enough it wasn't worth replacing. The local CompUSA here is going out of business, and they had some pretty great deals. I got two hard drive cages for the drives from my old system and this motherboard for a little over a hundred dollars.

Now I need the rest of the parts.

I looked to New Egg and I found a processor I liked, some RAM, and SATA drives I want. I'm thinking four sticks of that ram (two orders) and three of the SATA drives set for RAID 5, I also have a Pioneer DVD+RW drive from the old system and a floppy drive I'll want to put in this, and when I have the money I'll be adding a new DX10 graphics card to this box as well.

The part I'm waffling over the most is the Power Supply though, and the market seems to have changed quite a bit since the last time I bought one, with lots and lots of small companies making crappy power supplies, some start up companies making really good power supplies, and some of the companies I've trusted in the past making power supplies that only work with Intel based boards without mentioning it upfront (I'm looking at you Antec ).

New Egg has a deal with the case I want to buy that lasts until the end of the weekend where if you buy this power supply along with it they knock off $10 from the total. Not the best deal ever, but I've liked CoolerMaster kit in the past and it seems to have pretty decent reviews. Unfortunately there&... Read more

A:Building a new computer/Power Supply?

I have no experience with the CoolerMaster power supply noted. However, I have built computers with CoolerMaster cases which come with CoolerMaster power supplies.

Antec, IMO, makes excellent power supplies.

I have built several computers using the Asus M2N-E.

NE has an Antec True Power on sale, this weekend.

Long story short: I live in Kuwait currently, and I had to build myself a new desktop out here. Parts are not always "high quality", so things occasionally go "awry". And I'm a wee bit new to the PC building world, having been a Mac guy until March of last year.

I have two problems currently vexing me, but the first one is easy, so I'll start with it: I recently had to buy a new motherboard, and it had some funky power inputs that required a new power supply. Unfortunately, the only one I could find was 600 watts, which is probably massive overkill for one hard drive, a burner, a 3.4 Ghz P4, and a nVidia 6800 Ultra.

However, even though the power supply is properly installed (had a guy at the shop do it, and I double-checked the instructions at home), I'll be damned if it's not mildly electrifying my computer! It's not "complete the circuit and fry an egg" bad - it's more like "Carnival 'test your endurance' joy buzzer" at low setting bad. It's not enough to transfer to the outer case (the black outer shell), but it carries throughout the entire inner metal structure, and any screws attached. I worry that this is going to cause long-term damage to my computer, for obvious reasons. Strangely, a 500 watt power supply from a different manufacturer I had earlier did the exact same thing, which is why I'm wondering if it's par for the course for more powerful power supplies.

I'm going to take an old computer and use it to store music files and pictures so everyone on my network can access them. Right now all the files are scattered on four different machines which are never on at the same time, gets annoying. Can anyone recomend a power supply that'll operate good/cool under the condition of staying on pretty much 24/7?

I turned on my computer today, and it decided to not work on me. Whenever I pushed the On button, the LED on the front panel and the Power supply flickers on and off. I had a feeling it was my Power Supply, because weeks before this happened, I've been having to deal with all sorts of Problems. Computer would suddenly lag, then reboot..but when it reboots the computer gets to the Windows XP splash Page and I get the BSOD and it just reboots all over again. The only way I could get the damn computer to boot Windows XP was to leave it off for about 10-15 minutes. I had a feeling it was the Power supply over-heating, but I shrugged it off. The night before this happened, I opened up my computer and cleaned/blowed off the dusts inside. I put the case back on, plugged everything back and never bothered turning it on. Now, after turning it back on..my computer would just keep flickering. After unplugging the cord connecting to the PSU, my computer would still continue to flicker for about..1-2 minutes. I decided to take off the PSU, thinking THAT was the problem, but..now I'm lost..because I plugged in the PSU while it wasn't connected to the computer and it didn't flicker at all, but the fan wasn't running.

Model: ATX-250-12Z

A:Power Supply/Computer flickering on and off!

I know that one time when I was having problems with the power supply, the AC cord was damaged. Also, if you took your computer apart and weren't careful, you might have shocked something and destroyed an essential part.

The other night my power supply died on me. I have been able to trouble shoot my computer before but I am kinda stuck not sure where to go.

I installed a new thermtake 650watt power supply and ditched the old one.

I believe I have installed all power cables correctly.

After I hooked it all up i noticed that the power light on the front of my desktop was on but the computer wouldn't boot, no fans, or anything. I think I may hear I slight click when I do press the power button

Here are my specs.
Asrock fm2a78m-HD+ motherboard
AMD Radeon CPU
650 watt thermtake power supply

Any ideas or help would be great.

A:New power supply, Computer won't boot

At this point its tough. You could have damaged the mob when the old power supply died, it has happened before to other computers numerous times.

Are you SURE you have ALL the power supply leads plugged into the correct ports?

If so, I would unplug the power cable fropm the PSU to the wall outlet, then remove the CMOS battery from the mobo and press and hold the POWER button for 60 secs.

Now reinsert the CMOS battery and the power cable and see if it will boot now.

If still no booting, remove the ALL RAM modules from the system and try to power on, it should have a series of beeps if you have a mobo speaker connected and/or flashing light patterns.

I have a homemade system that just died. It has a Duron 900 that I know had been running hot (175 F). It also has a 375w power supply that also serves as a power strip. I removed the heat sink & fan to do some cleaning (spray air to knock off dust on the MOBO around the CPU). I broke one of the prongs on the socket that holds down the heat sink. A "friend" suggested using super glue to re-attach the heat sink. Now...nothing. The reset button lights up on the power supply, but the fan does not kick on and nothing else functions. Would a dead CPU cause this...power supply...MOBO...or a combination? Thanks for your consideration.

A:dead computer - CPU or power supply?

CPU sounds fried. Superglue? Really? I'd replace both the cpu and the board as you can no longer attach a heatsink to the board unless you have mounting holes and can find one that attaches with mounting holes.
