CX750M enough for 2 R9 290X in crossfire?

migkillertwo · May 19, 2015

Subject. I am about to upgrade my CPU to an FX8320 and video card to an R9 290X and my motherboard to a CrossfireX capable motherboard. My question is: can a Corsair CX750M run two R9 290x if I don't overclock?

No. You want a decent 1000W psu such as EVGA G2 1000W for a R9 290X crossfire build

No. And you will need to put a hefty oc on that 8320 or it will bottleneck a pair of 290xs.

^ No it wont.

^- in a cpu heavy game it will. Gta V is a good example. An i3 will outperform a 8320.

Each one should only draw around 220w in gaming, but can hit 295w so it would be cutting it close.

A newer i3.

But if outperforming is the same as bottlenecking, nearly everything is bottlenecking.

My 290 is a bottleneck cause i could have a titan X.

My 8320 is a bottleneck cause a 5960X is faster...

No.

Its a bottleneck because it won't let the gpus run at full usage. The fx series has poor single core performance.
