Can my HX750 power 2 r9 290's?

[umar rehman]

For some reason, I really want to crossfire r9 290's. But I want to know if an hx750 would do the job

My specs are:

i5 4670k @ 3.4 (May OC later)
8gb corsair vengance
MSI z87-g43
1TB WD hdd
120gb samsung ssd

No gpu at the moment because I'm asking this question before buying.

Thanks for reading

You could get away with a 750w as long as the cards never reach peak load, you either want a 850w or a 1000w. I would just get the 1000w so you can overclock later http://pcpartpicker.com/part/evga-power-supply-120g21000xr really good and cheap for a 1000w

Nope. You need at least 850W, especially if you plan to overclock.

No 750 watts is too light , go to 1000w for 2 - 290's.

One of the Best 1000w on the market made by SuperFlower.

R9 290 CF - System Wattage with GPU in FULL Stress = 603W/51 Amps.

A quality 750W like the HX will work, but i'd suggest 850W for more headroom & peace of mind. If over volting or using souped up 290's then perhaps consider going with 950W-1000W.
