OK so i see this posted everywhere!
So this is a heads up I hope it gets use because i have seen this probably 2 dozen times in the last couple months!

"My Power supply is screaming.." or "Under load my Supply squeals!"

Even on Boot sometimes this happens! A loud squeal that slowly goes away!
So I have a list of the outputs your Supply has and how you can see if it is failing!

Go to your Bios and see if your voltage is out of range! Nominal is what you want but of course your going to have minor variances. Just make sure your not too high or low. This can cause damages to components and/or function improperly.

You can also use Programs like SpeedFan a free Download:

Everest which is purchasable with a Trail edition:

And lastly with a multi meter at the Connection of the Powersupply

Pin Name Color Description

1 3.3V Orange +3.3 VDC

2 3.3V Orange +3.3 VDC

3 COM Black Ground

4 5V Red +5 VDC

5 COM Black Ground

6 5V Red +5 VDC

7 COM Black Ground

8 PWR_OK Gray Power Ok is a status signal generated by the power supply to notify the computer that the DC operating voltages are within the ranges required for proper computer operation (+5 VDC when power is Ok)

9 5VSB Purple +5 VDC Standby Voltage (max 10mA)

10 12V Yellow +12 VDC

11 12V Yellow +12 VDC

12 3.3V Orange +3.3 VDC

13 3.3V Orange +3.3 VDC

14 -12V Blue -12 VDC

15 COM Black Ground

16 /PS_ON Green Power Supply On (active low). Short this pin to GND to switch power supply ON, disconnect from GND to switch OFF.

17 COM Black Ground

18 COM Black Ground

19 COM Black Ground

20 -5V White -5 VDC

21 +5V Red +5 VDC

22 +5V Red +5 VDC

23 +5V Red +5 VDC

24 COM Black Ground

DC Output Voltage Regulation

Output Range Min. Nom. Max. Unit

+12V1DC ±5% (1)+11.40   +12.00 +12.60 Volts

+12V2DC ±5% (3)+11.40   +12.00 +12.60 Volts

+5VDC ±5%           +4.75      +5.00   +5.25    Volts

+3.3VDC ±5%(2)   +3.14     +3.30    +3.47   Volts

-12VDC ±10%        -10.80    -12.00   -13.20 Volts

+5VSB ±5%            +4.75     +5.00    +5.25   Volts

(1) At +12 VDC peak loading, regulation at the +12 VDC output can go to ± 10%.

(2) Voltage tolerance is required at main connector and S-ATA connector (if used).
(3) Minimum voltage during peak is greater than 11.0 VDC

So what you say Ill get a new one soon!

Long term possibilities of a failing supply!

ORIGINAL: Tom's hardware

If your PSU is 'squealing' its because it's capacitors are doing it because they are blown or corroding significantly, or electricity is arcing on the inside of the PSU. neither is good. if left untreated, you could be looking at something as small as a new PSU, or you could have to replace most components in the PC if they get blown out by a short in the PSU, or your PC could just ignite into flames from electrical arcs and dust and burn down your house...

sounds far-fetched doesn't it? yes, well, it's not. so toss your cheap chinese power supply and go spend your $20-30 on a new one from the store. my experience comes with advice -- don't wait until you start to hear the noise again, replace it now.

on a side note, if you're not sure it was the PSU making the noise, inspect your mobo's capacitors as well. if they are not flat on top, bulging out, showing signs of 'leaking' or corrosion/oxidation, then they are bad and potential candidates for your strange noise. check them all -- if they look fine, its your PSU.

quote:

ORIGINAL: PCGuide.com

Explanation: The PC is making a squealing or whining sound, coming from the back of the power supply unit. The sound may be louder when the PC is first started up, and then diminish, or it may get worse as the PC is left on for a period of time. Diagnosis: Usually, the cause of this problem is the fan on the back of the power supply. It will tend to accumulate dirt over time, and cheaper ones will fail readily. If the fan is making noise now, it will probably fail soon. This usually takes years, but with cheaper power supplies that can be a surprisingly small number of years. Rarely, the problem can be with the internals of the power supply itself. Recommendation:
Look and listen closely at the back of the PC to see if the fan is what is causing the problem. If it appears that the fan is making the noise, troubleshoot it here.
If you hear a high-pitched whistling sound, this could be coming from components within the power supply. This will require you to either replace the power supply or take the system in for service.

Regards,

Do you have any comments as to why the 200 series video cards cause the squeel in some power supplies and is this indicative of a failing power supply? or is is just a resonance within the supply that is benign?

Really would need a comparison chart of the PSU they are using on the Card they may be pushing the limit and causing premature failure or the 12vt rail is not rated for all the amperage they are pulling.

could you try my corsair 1000w psu and my gtx 280 ..it was either my gfx card or psu making the noise but i couldnt tell ...well my psu died because i plugged in directly into the wall! NEVER DO THAT! and it fried my psu but im just curious if you could figure it out for me since you seem to have the knowledge of figuring out whats going on....and it only happens during 3D applications!

Here is a run down of some of your consumption on average. Dont take this as a rant it is supposed to be helpful

GTX 280
Minimum of a 550 Watt power supply.
(Minimum recommended power supply with +12 Volt current rating of 40 Amp Amps.)

Corsair 1000W supply
+12V1@40A

You are at the minimum but your pulling even more power OC the card and CPU you are draining the rail to it limit and when running 3D apps it probably pulling exactly or just over 40Amps

GTX 280 750/1520/1220 fan: 70
Intel e8500 OC'ED too 4ghz

What else are you running? how many HDs Fans ect...
Today's typical 3.5-inch hard drive uses about 1 amp of +12-volt power
Each LED in a computer is pulling 17ma per LED in all those fans or .017Amps

So case fans say 5 with 4 LEDs per fan = .34 Amps

Each fan at 1500RPM pulls about .2Amps so if you have 5 fans there is another 1 AMP lost.
Mose people run 3000RPM on CPU so double that. if all 5 are 3000RPM thats 2 Amps

This does not take into account Extras like Audio card
And all the power and Voltage into the MB to run the required components.

Oh and add 5vt USB devices and Bluetooth
Logitech does not list amperage consumption of the G15 but that's full of LCD and LED lights

In your particular supply one rail is being used for the OCed system and the other rail is at the Minimum req for the GTX 280 and they you are over clocking it.

Hope this can help you out a bit maybe a 45Amp rail? damn scares me to want a 200 Series! dunno If I can afford the PSU

And don't forget a very important aspect of it all, Your PSU will only put out as well as the input from the wall meaning that if your outlet is not feeding enough juice to the PSU then the output will suffer. Look at the input rating on the PSU and you will see that it operates within a certain range, the lower end of that range will cause the PSU to strain. Case in Point, My outlets were on a 15 amp breaker and had 5 outlets on it ,which is typical of most houses and it can be worse in older homes, if my laser printer (which is networked) would start printing while I was in a games it would crash my pc. it took me awhile to put 2 and 2 together but i did and had a new dedicated 30 amp circuit installed just for my PC and monitor, also I run every thing though a APC backups 2000VA unit with AVR just to be safe and help keep the power clean.

You can do some trouble shooting by isolating the outlet by unpluging all devices from the wall that is on that circuit except the PC and monitor and seeing if the problem goes away (WARNING: if you don't know what you are doing stay out of the breaker box and call a electrician. the power in that box can KILL you). remember the old saying , garbage in garbage out.

Lol, did you know that a AA battery can kill you? I told my friend that and he was afraid to even go near his wireless mouse

. You can die from the power in a breaker box if you don't know what your doing. You can only die from a AA battery if you know what your doing (as in how). Gives you something to think about huh?

BTW great guide l337h4l.

A current of 20 milliamps or .020 Amps so compare that to a LED which can be run by a watch battery!

Of course you would have to directly run the current through your heart

Forgot to say "Don't try this at home!"

After reading your guide I might buy a new PSU when I get a new GPU. I can't recall how many amps are on my +12V rail but I know that there is more than enough. I think my PSU has 30 Amps on the +12V rail if I recall correctly.

At the time I bought my PSU I paid I think $80 (after small instant savings) for my 650W to get the rail current my GPU required. Now I see better PSU's being sold for about the same amount.

Your PSU rating should be displayed on the sticker of the side of it. 12V@XXA

Yeah was at work at the time I posted a reply so I couldn't. After your post reminded me I looked at my 650W PSU sticker and it says 12V@39A

. Guess my PSU rail current is higher than I thought.

In many cases, just because they put something on a label, doesn't make it true.

It's best to check yourself with a multimeter.

You're way off. 40A minimum is whats required to run the WHOLE SYSTEM, not just the card. HX1000 has TWO 40A rails, and they are configured in such a way that the card is on a seperate rail to the CPU. Even then the GTX280 power consumption is only about 15A, so even one rail at 40A is more than enough. The noise is caused by poorly designed power circuitry in the GTX2xx cards themselves, and not a sign of PSU failure.
