Im quite interested in getting an idea of what sort of power my rig is using, heard of theese wall tester units, anybody reccomend me one. Im a little concerned about my sli gtx 470's and i7 maybe drawing to much power from my psu, (corsair hx 850w). Particularly as ive been raising the card clocks to 800 mhz with added voltage, seen a few horror stories of similair systems dying.
