Well when going SLI or CF I always like to go with 850w or above to give yourself some headroom, not only that those cards are power hogger too. Also is the CX-V2 or just CX?

Crap. It is supposed to be "crossfire ready". Will this work http://www.newegg.com/Product/Product.aspx?Item=N82E168...

I prefer Corsair PSUs btw.


Corsair make good PSUs but seasonic PSUs are generally regarded as the best. (the XFX one i linked is made by seasonic). There are ofcourse loads of other great PSU brands out there like Antec too.

But the PSU you've linked is a great PSU, good choice :)
