PSU Problems With New Build? Or Gfx Card?

Hey all, recently finished building my i7 system which works very well and runs all my games spot on.

Anyhow I noticed earlier today that there was a screeching noise coming from the pc and it sounds like its 99% coming from the power supply (Coolermaster M700). Doing a couple of tests it is silent as a mouse when on desktop etc and makes its noise AS SOON AS i do anything using the graphics card more intensely - basically gaming.

Is the PSU borked or anyone have any suggestions? Its giving me a real headache when gaming

Thanks.

I'm not 100% certain, it sounds much closer to the psu though.

Just had another listen, definately louder at the psu!

Tried turning the fans to 100% on the ATI control centre and that didnt make the noise just loud fans but smooth fans. It seems from google that people have this problem with the 4870x2 but are never sure if its the psu or gfx, anyone got anymore light on the subject?

I'm still 99% sure its the PSU - I've checked all the cables into it etc. You can slightly hear the noise even when just working normally.

I'm going to do a final check with it out of the case and then if its the psu RMA it and buy another one, its making my ears hurt
