Electrical buzzing coming from computer when playing games.

[Maneens]

Hi, so the title pretty well says it all. When I'm just messing around in Windows, the computer is essentially silent other than the fans. When I fire up a game (such as Guild Wars 2) a buzzing sound starts. I just built this computer last night, is this something I should worry about. Should I RMA the part that's causing it?

It may be coming from my GPU or PSU, I'm going to try and isolate the sound now though.

PSU: Corsair HX650
GPU: Gigabyte Radeon 7970 Ghz Edition (1100mHz core clock)

It could be "coil whine". I had a Corsair builder series do it with a GTX 560 video card.

During the passmark graphics test, it would make a noise that had a doppler-effect as the jets flew around the mountain.

Run something that has a consistent (repetitive) GPU load like a benchmark or Kombustor stress test, and then get your ear close to the computer and try and pinpoint the source by ear.

I suppose the graphics card itself could make the noise too, but in my case it was the PSU.

When I was researching coil whine, I found that enabling v-sync "fixed" the issue for some people.
(I RMA'd my PSU)
