Here is Guru3D's power supply recommendation:

Radeon HD 7950 - On your average system the card requires you to have a 500~550 Watt power supply unit.
Radeon HD 7950 Crossfire x2 - On your average system the cards require you to have a 700 Watt power supply unit as minimum.
Radeon HD 7950 Crossfire x3 - On your average system the cards require you to have a 850~900 Watt power supply unit as minimum.
Note:they use a very power hungry test setup-

your system is much more power efficient.your psu(xfx 650) provides 53 amps which is sufficient to run your system with 2x 7950.
