    You should be fine as long as you don't turn the voltage up on the GPU's and CPU. Then the power use can go through the roof. Max clocks on stock volts should be safe. My 950TX hasn't had any problems with my 480SLI setup even with overclocked CPU and GPU's.

    Yes you'll be fine for GTX 470 SLI and overclocking.  Probably not extreme overclocking but you're not using or planning extreme cooling, are you?

    Nvidia's SLI zone even recommends the Thermaltake Toughpower XT 750W for two 470's. I run two 460's on it overclocked, with a 4.0 i7 920 D0 -- you should be fine.
