Absolutely!

AMD recommends a 550W power supply to power a system with one 6970 in it (I wanted to look at the 6950's specs, but you said they will be unlocked), so this means that they would recommend a 650W or 700W power supply for a system with two 6970s.

Better yet, the TX750 is a 750W continuous-rated power supply while AMD is talking about peak-rated units.
It's like advanced alien technology! :)
