My system is running globally at 460 watts when bf3'ing on my SLI rig with a corsair hx520w power supply. The 12v rail is supposed to handle 480 watts, combined, so it should be ok, but is this too close to the max? I mean... it's 460 watts running bf3 and 150 watts at rest, so I assume it's only taxing the psu around 300 watts, worst case...:whiste:
