Short list of good PSU brands: Antec, Corsair, XFX, Seasonic. For more detailed info you can check out the recommended PSU link in my signature. A few Specific recommendations:
1. Seasonic M12II-520 (on sale at Newegg right now)
2. XFX Core 550W
3. Antec High Current Gamer 520W
4. Corsair TX550 V2
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.
