That will be more than enough to run crossfire with the 7970's and the i5 overclocked :)

I've calculated and even with your cpu at 100% full load max you'd need is around 600W

Here is Guru3D's power supply recommendation:

Radeon HD 7970 - On your average system the card requires you to have a 550 Watt power supply unit.
Radeon HD 7970 Crossfire - On your average system the cards require you to have a 750 Watt power supply unit as minimum.

If you are going to overclock GPU or processor, then we do recommend you purchase something with some more stamina. Source: http://www.guru3d.com/articles_pages/amd_radeon_hd_7970...

SAME !

Edit : http://www.hardwaresecrets.com/article/XFX-PRO-650-W-XX... Check this 650 W

They are identical

Edit 2 : His max draw goes near 650-700 (addink frumark and prime95 ) so he is still ok !
