You at least need 800w. If you want to overclock gpu and cpu and you will need more headroom, and then go for 1000w. Ensure you get a quality unit.

I would get at least 850W, but if you are planning to OC you should get a bigger one.

A system with an i7 3960@ 4.6Ghz and 2 780ti's pulled 617w(total for the system not just the GPUs)

So really a good 750w PSU would work, but I'd still recommend 850w especially if you want to OC.
