THat's a good power supply and more. I have the 500watt version of that without the triple fan.

Just to say one thing - for SLI with 2 x 7800GTXs, only a 450W power supply (IIRC) is recommended, and these 7900GTs are likely to be much more energy efficient. Nevertheless, you've got a good one on it's way
