Is 460watt load ok for 520watt psu?

[Ozark_86]

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:

What are you SLIing? Is 460 from the wall?

What are you SLIing? Is 460 from the wall?

I was wondering the same thing. That PSU is 80% efficient through most of the range...which would mean the PSU is actually putting out about 370 watts...well within it's comfort zone.

Yes, I have a kill-a-watt that I'm measuring from the main power cord to the wall, 460 watts, under load, for the entire system. I'm SLI'ing two gtx460's and IIRC tom's site had that draw at 319.

If the 460 is from the wall, then you are fine.
