PSU Question.

Will a corsair GS800 support radeon 7970 crossfire?

 

[timarp000]

The GS800 can support 7970 CF as a single 7970 need a minimum of 500W(inclusive of CPU, ram etc). You still have 300W to spare and a 7970 consumes much less power than 300W.

You will be fine

If you have cash i suggest you buy a modular power supply like a TX850M or HX850 from corsair
