What wattage will I need to run R9 290x in CF.
Some people say 1000w and some 850w,
but look what I found:
http://www.guru3d.com/articles_pages/radeon_r9_290x_cro...

It says at FULL LOAD 661w (it wasnt't just the GPU's, they had to have a cpu to test it so dont say ill need 1200w)

I was thinking of getting the Corsair RM750, will it work with that one?

Thanks in advance :)

Just to be at the optimal range of the PSU's efficiency, i would go with the 850W. But it will work fine with a 750W psu.
I would recommend the Corsair HX750, it has been on sale lately for around $100, and a little less with rebates and it is clearly the superior PSU vs the RM750 80+ Gold rated and all.
