Crossfire PSU Requirements

[Zade_95]

Does anyone have an idea how much power a 290X + 390X crossfire setup? Currently got a 750W Gold, thinking it won't be enough.

 

Thanks!

what's your CPU?

if you don't plan to do overclocking and the 750W one you have is a good quality, then that should be just fine

for Z97, Z170 with overclocking I'd go 860W

and for X99 with overclocking I'd go 1000W personally

that's enough, you shouldn't have any issue

I think 750W is a bit low for the PSU to operate at its maximum efficiency, especially if you overclock. 860+W would be safer imo

I probably wouldn't overclock it, my PSU is a FSP Aurum 750+.
