So I currently have a evga supernova 1300 watt psu (it was a sick deal lol). I'm having some emi problems with my xlr mic which I think is some sort of ground issue and I'm wondering if I can use an old ocz 600 watt psu to test if the buzzing is still there with a different psu. Is 600 watt enough to power my pc without any problems with my specs below in my signature?
