View Full Version : Is this a reason to complain
I have Corsair 520w power supply. Recently I built a low power consuming system, probably under 100w when idling. There is no problem with functioning of the power supply. There is certain high pitch noise when psu is idling. The noise goes away once system is under load.
I am not happy with the noise because it is driving me mad. What do you think, is that a reason to complain?
Yes, the noise comes from inside of power supply. It is not cause by fan.

Go over and post your problem on the Corsair power supply forum. I have seen them RMA noisey PSUs before.

Is it the rig in your sig?
If its not, maybe theres not enough of a load on it?

it's probably one of the capacitors making noise. when it goes under load it varies power passing through it to some frequency that doesn't cause it to vibrate and make that high pitched noise you are hearing.

So should power supply do that or not? It is freakin annoying sound

I remember when i got the PSU i have now, and i put my Pentium D system on it, it would do that same thing at a complete idle. But when i built this i7 system and put that PSU in it (~2 weeks later) it stopped. Probably is due to the PSU being underloaded.
I've got a solution for you.. it's a software solution, and won't actually change anything hardware related. It only happens at idle, right? Run F@H, or Rosetta@home, and never let it idle.

Yeah, I could do that. I noticed when I primed even with one core the noise went away. Still, I don't think power supply should do that. Anyways I contacted corsair for replacement. The said that 520w was discontinued and sent me 620w. I got today, installed it. Bam the noise is gone.

Definitely from underload, not that it matters. I can hear transformers for small plug in devices that make a noise when the device isn't plugged in.

The lower the load, the narrower the pulses, and narrow pulses can be noisy.
It wouldn't surprise me if the APFC was doing something, too.
I've read that noisy coils and transformers can sometimes be fixed by coating them with more varnish, preferrably applied by dipping them in hot varnish to make it thin and runny and doing this in a vacuum and under high pressure so that the varnish will displace any bubbles and leave no voids. You do have a vacuum/pressure chamber, don't you? ;)

Can I get that 520 off you? :santa:
