3 7950's on a 850w PSU?

[Hippievogel]

I have a rig that's been running 7 months with 3x 7950s getting 1900kh total  on a hx750 psu pulling 700w from the wall

psus differ very much, despite the label. Some may even work above reported load for hours, while other die at 80%. There's usually a number on a label per each rail or set of connectors for MAX load.

cheap brands/ cheap psu always combine the total load as you can see it is a 700w psu(If you look better you can see the load on the 12V is 600 only), mine ax860's can handle 852 alone on the 12V)
I think the way to go psu's are the ax860,ax1200(7 Years pick up warranty), some platinum seasonic's, Lepa g1600(not sure about warranty but 5+ years for sure) and the Evga Supernova 1300 G2(10 years warranty). I dont see any other Psu being a good bang for buck value.

EVGA Zupernovas <3 G2 1300/1000 and P2 1000 are all great in my book.

Too bad they are gone nearly everywhere, and anywhere they are to be found is $50-75 over retail, and $100 over what I paid on black Friday...

Guess I have good taste in hardware  

And the 1.5K supernovas are unstoppable beasts, as in they will give you 12V till the wiring in the wall melts. Here is one running 5 290's at clocks that are no slouch, I left this going for a few minutes then stopped it before I burned my house down  



They will do more on 240V
