Which PSU should I buy?

They're just making noise at this point, but they don't really matter—it's all just empty talk.
Standard practice is to check the reviews to see what the entire rig pulls under a full load.
For instance, a GTX 760 SLI setup according to ers hits a peak of 449 watts, and their CPU was an Intel Core i7 3960X (130W).With overclocked versions of the GPU, they hit 478W in FurMark (though likely less during actual gaming), paired with an i7-3770K @ 4.0 GHz. Essentially, you just need to ensure the unit can handle that much on the 12V rail while leaving some breathing room.
And obviously, you want a high-quality power supply—look for reputable brands, various 80+ certifications, read the reviews, and so on.
In short, an SLI setup could probably run on a 550W unit, so a 650W would be more than enough.

But honestly, instead of messing with SLI, you're better off just getting one single, more powerful card.
