Psu buzz

Hi

Just recently got a ocz z series 1000w psu and when i run benchmarks like 3d mark vantage and the stone giant benchmark my psu makes a annoying buzzing sound.

It changes just pitch just by moving the mouse around the screen is it on its way out do you think or is it normal on some psu.

The buzz is quite loud.

is the noise coming from the psu when you put your ear to it, or the noise come though speakers or headphones.

Hi

It definitely is the power supply guys i have tried it outside the case and the
annoying buzz is still present even tried it with one gtx 480 and no overclock and it still there.

I cant put up with the sound so am going to invest in a new psu which hopefully will not have the same problem i was looking at either corsair HX 1000 or Enermax Revolution 1050W PSU any other suggestions welcome.

Thanks.
