CrossfireX HD 7970s

[Laayf]

Hi I was thinking about adding another HD 7970 to my computer I was wondering how much power I would need.

Quad Core Intel Core i5 3570K
2x 8GB DDR3 Ram
Gigabyte GA Z77X-UD3H
Antec HCG-750W
Is this power supply enough?
Thanks

It would be pushing it, but it might do it, I had a HD 7850 crossfire running on a XFX 550w, but it did die on me eventually. (3 Months later)

Not even pushing it, that unit will handle 7970 cf fine. In fact that is the recommended wattage for 7970cf

7970 is not a 290x, so you will be fine.
