My computer is less than 6 months old and ever since I got it the power supply sometimes makes a whining noise. Even when the computer is off. It's a 600W ATX Corrsair. Is there anything I can do about it? I've got it plugged into a UPS.

1Please give a little detail about what they say and why they're useful. – James Mertz – 2012-07-02T10:07:25.123
Neither link seems applicable. The first links seems to be about fan noise. The second link is about electrical noise, not audible noise. – sawdust – 2012-07-02T19:05:02.493
@DragonLord bizare that question is the same as mine (and I asked mine 2 years earlier) and it got 24 upvotes – Celeritas – 2014-10-28T21:19:45.207
Is it a fairly high pitch noise? Mine has a noise when shut off as well. I've got a CX500 Corrsair which does the same thing. I think it might be some capacitor that just makes that sound under "shut off" conditions. Get a powerstrip with an on/off button? That's what I did. Btw, my gfx also makes similar noises under high frequency loads when it runs. – Zoomulator – 2012-07-02T09:44:34.607
Give it a cookie! Or pick it up and comfort it, it might just be missing you. – lornix – 2012-07-02T11:23:47.397
If it's a high-pitch noise, then the PSU is probably under-loaded (i.e. a 600 Watt power supply is too much capacity for the low-power draw of the PC). ATX PSUs tend to be tolerant of small loads, but there could be exceptions. Try connecting a Kill-a-Watt meter to measure how much (or little) power that system really uses. – sawdust – 2012-07-02T19:11:12.270
