Is it the X-Series 560W gold? If yes, it should have a 46A rating at the 12V rail. If that is the case, it is perfectly adequate of powering all of the cards you mention. One at a time ofc :p

Yes. That's the PSU I have, and it is running my HD7870 with an overclocked Phenom II without any trouble at all.

(not for long though; will be moving that card into my i5 rig as early as this weekend)

No issues there. Will work unless you forget to connect power cables to your 7950 :)

nVidia itself recommend 500W for a single 670.You'll be fine Here is Guru3D's power supply recommendation:

Radeon HD 7950 - On your average system the card requires you to have a 500 Watt power supply unit.
Radeon HD 7950 Crossfire - On your average system the cards require you to have a 700 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.

System in IDLE = 165W
System Wattage with GPU in FULL Stress = 300W
Difference (GPU load) = 138W
Add average IDLE wattage ~3W
Subjective obtained GPU power consumption = ~ 138 Watts

Mind you that the system wattage is measured at the wall socket. Source:
