Static noise?

[Failsnipe]

Hi, upgraded my rig about a week ago now and my PSU seems to be making an electrical/static noise under high load in some games (cod4 and sims 3 are the worst offenders)

Anybody else had anything like this and is there anything i can do to solve it besides sending it back and getting a replacement?

pc specs are:

asrock p67 pro
i5 2500k @4.5ghz
corsair 4gb ddr3 1600
palit gtx 670
akasa venom 750 watt

Its deffo not the graphics card, and my last psu had a distinct whining noise. This sounds like electric passing through two points opposed to just squealing. And yes the psu and graphics card are both new
