PSU Whine

[NvidiaDan]

Hey guys, just finished my build and have noticed a very high pitch squeal/whine while the PC is on standby which I can see getting pretty annoying!

Not had a PSU do this before so does anyone know what might be causing it?

It's a EVGA Supernova 750w G2

Thanks

It's most noticeable when I put my ear to the back of the PSU. Could the GPU be capable of making a noise even though the PC is off?

Cheers guys, literally only received yesterday from ocuk. Spent hours today managing cables so what do you think are the chances of me being able to send back just the unit without cables?

Really don't fancy pulling apart the whole system!
