How much is 706W from the wall with 90% efficient PSU?

post #1 of 4
Thread Starter 
My AX850 is 80+ Gold certified which I guess is 90%. I ran Prime95 and FurMark on Xtreme burning mode at the same time and my rig pulled a nice 706W from the wall, how much stress is that on the PSU? Thank ijn advance!

635W pure, if the PSU is really 90% effective. AFAIK 80+Gold is 88%, which would be 621W pure.

Calculation goes (W at wall x eff %) / 100

But efficiency varies with load, temperature and input voltage. So it's not going to be a set number.
