hi there techspot,

i am beginning to learn more and more about hardwares, and i just want to know what power supply is compatible for a certain processor. Like for example, i have a pentium 3 800mhz processor, how many wattage does it take to power up such processor as P3??? does this processor has its limits when it come to power supply???

I fixed my harddrive problem but now i have an even bigger problem
Last night at around 1:00 my computer shut down
I powered it back on and it stayed on for about 5 minutes then shut down again
What i want to know is if the power supply is going bad (it smells burnt)
The little green light shows that power is still going to the motherboard but it will not power on unless i leave it alone for 10 or 15 minutes
I'm pretty sure its not the processor since i removed the heat sink (being careful not to smear or remove the thermal paste) and it seems ok
I've had something like this happen before but the motherboard was fried (power surge, anyone that has heard about e-machine mobos and their psus knows what im talking about)(this is not an e-machine)
I'm not sure (i'm ignorant when it comes to motherboard, psu, and processor problems) but it might have something to do with the switching of my harddrives every 5 minutes
Anyway I want to know what exactly could be wrong, and if theres anything I can do to fix it
Thanks in advance
^_^
ps: not sure if this will help but before it started to shutdown and smell the computer stopped recognizing harddrives and would only recognize them if i switched which psu cable they were plugged into

One last thing that confuses me to no end
Anything that i plug into the motherboard works (mouse light comes on, mp4 starts charging, etc...)

Burnt smells are really not a good thing, and indicates that your PSU is pretty much 'toast'. Get it. "BURNT" "TOAST" HILARIOUS!!

Sorry, that was really bad.

Anyway, your PSU is not safe to use anymore. Get a new PSU and see if it solves the problem. If it does, then you're good to go. If not, it's likely that your motherboard was damaged as well. Processors rarely fail, so I'm more apt to believe that it's the PSU and/or motherboard.

So I primarily use a Mac, and before they released their core duo's that could run OS X and Windows I purchased an inexpensive eMachines T3120. Although I primarily use a Mac I am fairly well versed in both operating systems and have built my own Window's based systems in the past and have successfully been able to troubleshoot hardware and software issue in Windows without many problems...until now!

The History:
When I still had it there was one time it seemed to go into a permanent sleep mode but I was eventually able to get it out. I assumed it was a software glitch with windows.

I recently sold the computer to a friend who after two weeks had a similar issue. I had him restart spamming F8 to load in safe mode and the problem seemed to go away. It had been a few months since it happaned to me.

Well a few more weeks later it seemed to have the same issue, but now nothing will fix it.

Here is what happens:

When you turn the system on the Hard Drive light comes on and the fans come on. Keyboard lights do not come on nor can you use the CD-Rom drive.

After doing some research I condluded the MoBo must be burned. I replaced the Mobo with a brand new one and things were exactly the same, no difference. I did a little more research and have come to this conclusion:

The Power Supply is burned, the CPU is burned or the MoBo is burned...or all 3?

I know it cant be the harddrive, or else i would be able to boot from the CDrom.

A:Mobo, Processor, or Power Supply? Or all 3??

You can approach this in two ways. One is just to replace the PS. The other would be to remove everything non essential for posting. Just leave the HS/fan/CPU, RAM (if you can or it applies one stick at a time) and video adapter. If that doesn't work try the same set up with the MB out of the box on a non conductive surface. Then when it still doesn't work replace the PS.

I've read prior strings and listened to the advise. My Emachines T2865 was suddenly locking up and shuting off on its own until 1 day it would not boot. Took to a service center and replaced my Athlon XP 2800+. Everything seemed to be ok until I started burning some MP3's and would not get full burn of the tracks on my burner. Replaced burner and added TV card. System seemed to be running very slow so I checked the processor. Windows and the AMD CPUID tool said 1.252 at 100 mhz. The jumpers on the board are at 166 setting, the bios does not allow an adjust to the FSB but reloaded the Bios settings anyway and still it says 1.252 / 100mhz. The Mobo is a FIC AU31 with no capabilities to set clockin other than the jumpers on the board.

Why is my new processor running at half speed. Is the Mobo bad or can a dying or intermittent power supply cause the Athlon to run at half speed??
 

A:Is it my MOBO or is the processor or power supply causing my system to run at 1.252

the bios is telling it to run at that speed . maybe try and use a windows utility to overclock it . or see if emachines has a bios update for it . its a nforce 2 so u may be able to use ntune on it ...

I hope someone knows definitively because I've gotten conflicting information from IT professionals (at a certain school which shall remain nameless) and a couple other seemingly very knowledgeable persons at a new and used computer recycling wharehouse.

I had a 235 watt power supply with the Pentium 3 450,(which went bad) and two people said I need the same wattage or it could fry the motherboard, CPU and everything else. Two more said no, "This is an ATX as well, so don't worry. It won't(pointing at the plugs and wires attached to the new power supply) send more power than your computer needs to draw."

More information about the original power supply: HIPRO model: HP-235ATXAK
AC input: 60/50hz 115V~/6A, 230V/3.5A
DC output: +5V :::/ 25A, +12V ::: /8A
-5V:::/0.5A, - 12V:::/0.5A

New power supply: AG II SATA ATX

DC output: 3.3V +5V +12V -5V -12V +5VSB

It's been a long time since I've taken any electrical training, so I do know how funny electricity can be...an amp can kill you, (just one) but it is possible to survive a lightning strike. Errr, I digress...I just don't want a deep fried compy.

The processor I'm using is an A64 3200+ ( 2.2ghz ) socket 754. My question is.. if I OC it to, say, 2.5ghz and runs stable, would it be at the same speeds as an A64 4000+ since they have the same L1+L2 cache, which would basically make my A64 3200+ have a performance rating equivalent to that of an Intel 4ghz?

Just curious.. I've always assumed it worked this way but I'm no tech guy so I want to just get it clear.

Hi all,
RAM PROBLEM: I want to SLIGHTLY overclock my RAM. Its 512MB, DDR2 533Mhz.
But I am confused, how to do it.
Let me tell you the options available for RAM is my mobo's bios:

1. DRAM Timing:
a. Auto
b. Turbo
c. Ultra
d. Manual
DRAM CAS# Latency [DDR/DDR2] 2.5/4(current setting)
DRAM Bank Interleave 4-Way
Precharge to active (Trp) 4T
Active to Precharge (Tras) 7T
Active to CMD (Trd or Trcd) 4T
REF to ACT/REF to REF(Trfc) 25T
ACT(0) to ACT(1) (Trrd) 3T
Read to Precharge (Trtp) 2T
Write to Read CMD(Twtr) 1T/2T
Write Recovery Time (Twr) 4T

2. DRAM Driving: Normal
High

3. CPU PnP Setting > DRAM Frequency:
200
266
333
400
533
666
Auto(current)

Now, which of these settng I need to change to overclock my RAM?? And by how much???


Problem With CPU:
My Processor is Pentium D 2.8Ghz.
200(Bus Speed) x 14(multiplier) = 2800mhz
Now, when I slowly increase the BUS speed from 200 to 223, everything is fine. Under stress too, there is no problem. But as soon as I change the FSB to 224 or higher, my whole harddisk becomes corrupt. I need to reinstall Windows again after this. One time, even WinXP setup was not running by booting with setup CD. That time I installed win2k(it ran) and then installed XP. After that incidence, I have never OCed my CPU over 223 Bus speed.
Now, can u guess what may be causing this problem??

Thanks in advance

A:Help Needed: RAM OCing - Confused and CPU OCing - Problem

To slightly overclock your ram you'll need to set the dram timings to auto for now. As you speed up your FSB, your BIOS should automatically increase the memory timings to ensure stability. Set the dram frequency to 533 and then slowly increase the front side bus. After you have the FSB set you can then set the dram timings to manual and tighten your memory timings one at a time and then test for stability.

As far as your hard drive is concerned, it sounds like when you increased the FSB frequency your South Bridge frequency also increased. South Bridge devices (like your hard drive controller card) don't usually respond well to an increase in speed, so the card scrambled your hard drive. There should be a South Bridge lock in your BIOS. Your South Bridge should remain at 100MHz if it's a PCI-E based SB or 33MHz if it's a PCI based SB.

Now I may be completely wrong about your hard drive problem. Your processor could have over heated and caused the same thing; your memory could have spazzed and caused the same thing.

Honestly there are far to many variables to be able to help you at your current level of knowledge, and I don't know much if anything about overclocking DDR2. You need to read as much as you can about overclocking. Then start slowly and overclock you processor. Pull back and overclock your memory. Find out what will be your limiting factor (either your processor, memory or motherboard) and set up your BIOS to run as ... Read more

The laptop is in pristine condition but shows no signs of life. When I plug in the power supply the green light on the power supply goes from solid green to blinking rapidly to the point you can barely see it. To me that would mean a short somewhere right ? If so where ? Has anyone else ever had experience with something like this ? I just don't want to go buying a new battery for a laptop that maybe fried already. Any help would be greatly appreciated.

Hi, so I have had a powering issue with my previous power supply which was the Corsair CX600W so i purchased a newer power supply - the EVGA SuperNova G2 550W. I unhooked my old psu, hooked up my new one and the PC turned on and I turned it back off from the power button on the case. I also hava a boot drive problem so I unplugged the sata cables from my SSD and wanted to try to turn on the PC with only my HDD. I did this with the PSU switched off and the power cord unplugged. When I tried turning the PC on again the PSU made a clicking noise and nothing turns on. The motherboard Led's are lit up so it is definitely getting power but when I go to turn the computer on it just makes a quick clicking noise and nothing turns on. Any help is appreciated, thanks!
 

A:Power Supply makes clicking noise when I press power button

You may just need to drain the power off from the power supply and try again. Unplug the power to the power supply, press and hold the power button for 30 seconds, then plug it back in and try to turn on the computer again. If that doesn't put the old power supply back in and see if the PC works, or was the old one dead? If the PC works with the old one and not the new one then you may have gotten a faulty power supply.

Ive removed all parts and tried powering up and i cant get it to boot up. But the PC seems to work fine with the oldish 450 watt PSU which i find just unbelievable.

Can anyone help with this nightmare? Now on the Gigabyte site the CPU i have isnt listed as supported by this motherboard which is kinda worrying could this be the reason? If so how the old PSU boots up.

if I read the specifications right on your mobo... it implies that it has the 4 pin PCI-e input(power) but it also has the 8pin ATX power conector. (it may be simply removing a cap that is actually right next to the 4 pin connector, thus making it an 8 pin connector (thats how it was on my mobo)

Try using the 8pin power with your new PSU, see if that works.

I'm interested in the Toshiba G25 laptop but have heard that you can't use it on airplane seat power. It comes with a 120W AC power supply (15Vx8A), but I've been told that most airlines limit seat power to 75-90W max. Lind sells a 12V car adaptor for the G25, but specifically won't include an airline plug for this reason (which I can get independently, of course). I've read some interesting electrical discussions on this board. Can ya'll comment on the following or provide any general advice about power consumption?

1) Given that the voltage of the laptop and airline seat power pretty much match up (12-15V), if the amp draw on the laptop exceeds what the airline power supply can deliver, what will happen? Will it damage the laptop to feed it insufficient current? Will it shut down the laptop altogether? Merely dim the screen?

2) If I remove the laptop battery, which requires power to charge it, how much will that reduce the power need of the laptop? I'm not sure how to work the math, but the spec sheet states the battery supplies 4400mAh at 8A output. Does it require the same to charge it?

3) Most importantly, on my 15 hour transpacific flights, will the DVD player work with that ultrabrite screen at the low airline power supply? A nice feature of the laptop is that you can watch DVDs without powering up the Windows operating system (it has a small linux OS for the DVD player). Granted, the DVD drive and screen are prob...

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've recently inherited a lovely Y70-70 touch from my father, and have restored it to factory settings recently. However I'm having issues at the moment where it shuts down instantly at random times when not plugged in. Checking the system logs in the event viewer I see the following Critical message: The system has rebooted without cleanly shutting down first. This error could be caused if the system stopped responding, crashed, or lost power unexpectedly. Generally online help seems to suggest this is a power supply issue. Have I got a duff battery in here? Are there further diagnostics I can run? Unfortunately I'm out of warranty so keen to solve this myself!

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.

Sorry I don't know the proper terms, but basically the pin inside the jack where the power cord gets plugged into on my laptop was bent so that it's really hard for me to plug in my power cord and have it stay in place. My warranty with best buy has expired, so I need to figure out how to solve this problem on my own. I can't just leave it like this because the cord comes out really easily and I can't continue to work with such a tenuous setup. Anyway, is this just a matter of replacing the entire unit inside my laptop? I know you probably need more information, but I'm not sure what to provide, so please ask any questions. The laptop is a Toshia M-45, about 3-4 years old. Thanks in advance

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.

I shut down my Pavilion Elite for 1 week while away and now it will not turn on. The power supply light is on, I replaced the CMOS battery and the power switch is ok.

As you did not mention any message or display on the screen, I would use this tutorial for a step by step diagnostic.  It also helps to remove the side panel, and visually watch the CPU and rear case fan movement(s).  As you press the power button, pay attention to the fans. Also does the Power Supply LED stay ON? Or did it go OUT when you pressed the power button?

Hi forum and pc gurus,

My problem is specified down to my PSU, at least I think so. (550W Logisys PSU - maybe the quality has something to do with it, I paid $19 for it from NEW EGG). I have A Gigabyte GA-965P-DS3 Motherboard, a Intel Core 2 DUO Conroe 2.13GHz processor with heatsink and Fan, Sapphire ATI X1950 Pro, 2 GIGS of WINTEC DDR2 PC 6400 (800) RAM, 1 SATA Maxtor 320 GIG HD, 1 2.5 inch SATA 160Gig HD, and two DVD Burner Optical Drives (both IDE).

I have it hooked up like this, two Optical Drives connected to 1 IDE connector/cable which is hooked into the IDE input on the motherboard, both are set to slave. Two CD outs (connected one to each Optical Drives) to one CD input on the motherboard. Both HD's are connected to SATA inputs on the motherboard, one is set for master, one is set for slave (I heard that it did not matter but wanted to state that anyway), then my ATI RADEON X1950 is hooked directly into my only PCI Xpress 16 slot. The power connectors are then all hooked into their respective inputs on the drives and Video Card. ANd last but not least, all the Power button and LED connectors are hooked into their input on the motherboard, wich I set up exactly as the motherboard diagrams and directions directed. I turned the switch on the PSU to on and I only got a faint mouse like squeek, then nothing, not even the fan. So I figured it was DOA, so I had newegg send me another. I got it today, installed it, hooked all the power connectors to the hardware, th... Read more

Yea...so we finally got my girlfriends new PC up and running. The problem im having...or more of a concern really. Is when you flip off the power supply, and then flip it back on, the PC gets a short burst of power. IE the lights and fans all come on for a second or two. Then you can press the power button and turn it back on.

Any ideas guys?

Hello to the HP community. I must warn you all, this is a long thread and is potentially confusing, so only read this if you're interested in giving feedback. I am here today to not ask a question, but to share with you my confusion on your Pavilion desktop PCs. I've looked at the technical specifications for many of the Pavilion desktops, including my own, and I simply can't understand one thing; where do you get your PSU power ratings from? I currently have a Pavilion 500-319na: http://support.hp.com/us-en/document/c04343438.It's a good computer, powerful in most areas although the GPU isn't, so I'm looking to upgrade it. The first thing I check before I upgrade parts, and hopefully others do too, is the PSU's power rating. And this is where my problem lies. Firstly, your website states that for my PC, and others, it's an external power adapter. It simply isn't, as it's inside of the PC. I've seen in many discussions that this has confused people, including myself. And secondly, your website states that for many of the Pavilion PCs, including mine, the PSU is rated at 180W. Let me tell you why I believe is wrong: The PSU that comes with my PC, and presumably other Pavilions too, has four power outputs: 3.3V (12A) and 5.08V (10A) outputs, 'limited' at 70W. Then there are 12Va (7A) and 12Vb (10A) outputs. These apparently produce 180W. First of all, the 3.3V and 5.08V outputs can't be limited to 70W, in theory. This is because, using the equation...

You have pretty much the same problem as me (getting BSOD's randomly). For me it's bulging capacitors on motherboard. You should take a closer look for capacitors on your motherboard. Dead capacitors look something like that:

Hi !! All,

Happy New Year to all members and technical assistants.

I have a little issue in which I require some help and guidance.
I have a PIII 900MHZ 256 MB memory with a ASUS MB-

Recently it died on me and assumed that the reason I could not get to power
it up is due to my power supply. I went out and spent the money and bought a brand new power supply from a computer retailor. I saw him remove it from a brand new case.
I installed the power supply , trying to power it up, I can see the fan rotate a little bit but not enough to power on. Changed socket and it power on.
It booted up but after 30 sec, it shut itself off and now I cannot power it back on until 15 min. later when I went and change power socket once more.
This time, the power did not stay up very long. As soon it powered up, no more than 1 min later while it was loading windows Xp, it shut itself off nad now again can't power it back on. I have a power extention and power bar in which I used and both shuts the computer off. Anything else plugged to it doesn't seem to do any affect. This is the second new power supply I'm trying.
What else can it be ? I have not tried to place the computer in a different room on a different plug yet. I will try that tonight but in the meantime, what else can I try ?

Thanks for your help and listening.

Cheers !!

I have a generic MB (P-120 CPU ) which I just switched to a different case and power supply. It has an extra "six pin power type connection" in the middle of the board. Only one supply that I have matchs this and the wires are three green and three black. What is the funtion of this connector, it looks from the wire colors to be some form of switch.

Its a case of not wanting to swap out the power suppy from my other unit unless necessary. I have 4 other supplies and none have the extra wire, which is listed as P10.

Many thanks in advance.

Sounds like typical extra +5V lead and can be used for any number of things...(riser cards,backplanes,to drive extra slots, etc.)
Without knowing the specs. on your motherboard this question is impossible to answer...Post Mobo identification (make/model) or obtain FCC ID and post that. Perhaps we can find a more definitive answer for you...BOL

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.

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.

Finally broke down and started building a new system -
I'm too old to game, this all started out as a home video
project.

Anyway - gathered all my components, now I'm working
to assemble them.

The case came with an Okia Model 500-ATX power supply.
But no wiring schematic.

I'm trying to identify the power supply fan plug - what seems
to be it doesn't at all match the connector on the board.
And I've got that positively identified by the board manual.

The board has a small male 3 pin connection. The only thing I
can find that might be the fan connector coming from the
supply is a small 4 pin plug at the end of 1 of the strings of
drive power harnesses. Nothing tucked up behind the
supply case or anything.

Is that likely to be it? Or would that be for a floppy or something?

I tried to Google for a wiring schematic, but could find nothing.
In fact, nothing much at all on this brand of supply - just
a couple places that sell them. Please don't tell me I got
an el cheapo that isn't worth having!

At the risk of getting ahead of myself, in case I need to adapt
something like that to the different style male connector on the
board, in this case or something else I may find as i progress,
is there some type of source for adapters, or what would I do?

Bear with me, this probly won't be the last question I'll dream up -
just getting started.

A:New power supply, no schematic, looking for power fan plug.

There are basically two voltages available to you: 5V and 12V. Doesn't really matter where you get it from - some pin on the mobo or some wire from the PSU.

From the PSU the yellow wires are 12V and red ones 5V, black is ground. The fan voltages should be written on the fan itself, the black fan wire is ground, red may be 12V or 5V depending on the fan voltage.

Fan headers on the motherboard should be labelled so, check with a voltmeter what pin gives out what.

Ok so lately I have been getting a BSOD at very random times and it looks like a Diver Power State failure. SO all of my friends and every website I go to makes it seem like I need to get a PSU. Right now I have a Quad Core and a 8800GT and 375W PSU. So my friend told me to get a new 700W PSU.

So, if the only fix is to get a new PSU? I tried to rollback my GPU driver but it didn't help.

So any ideas?
