How big of a PSU for crossfire 290x?

poblopuablo · May 3, 2016

I just picked up 2 290x's gonna water cool them one with kuhler 620 and other with h55 both with a nxzt kraken g10 And vrm mods. Rocking 32 GB ram, 64gb ssd, 1tb hdd, 4 - 120mm LED fans, and 2 140mm LEDs. AMD 6350 with hyper 212 evo. Blu ray and DVD drives. Also a tp- link n900 card. I currently have a 850w. But maybe no should bump up higher? Not sure.

thanks!

A quality 750W will suffice, but as soon as your whole system is under load, you'll be at like 80% load on the PSU, so it's going to be very loud. I highly recommend just getting a 850W (current - we don't know the quality of it!), or even a 1000W for a slower rotating fan.

The TX850 is a good unit, but considering its age and the high power requirements of your hardware, and upgrade is a decent idea.

I recommend a solid 1000w.
