So i want to buy a second GTX780 and have a 850w PSU. Just wanted to know if it will be enough to support 2 gpus because when i go on asus tech psu calculator it says i need 1100w and when i go on extreme power supply calculator it says i need 700w.

Corsair 750D case
MSI G45-Z87 mobo
I5 4670k with H100 cooler
2x4 GB DDR3 (1600mhz)
evga gtx780
Corsair RM850

asus probably considers capacitor aging after years of use.

Looks to be true, if you add ~50% aging on the extreme psu calculator you'll get ~1100 rated on the extreme.

Yeah, 850W should be plenty for two 780s. I'm going to SLI them in a couple weeks here on an 860.
