Will this PSU support a Gtx 680?

Yep.

Theoretically, the power is there to do SLI/X-fire but, alas, the connections are not. For a GTX 680 card, you need two 6pin PCI-E connectors (you have that) but that leaves you nothing for the next GTX 680 to power it other than using an adapter from one of your peripheral connectors. To add to that (and also why it only has the two PCI-E connectors), the two 12V rails combined only put out 552W and each rail is limited to 300W.
A good rule of thumb (I've discovered) when looking for a SLI/X-fire capable PSU is to see how many PCI-E connections it has (vs. how many the GPU's require) - that will relate very well to how much power is actually available to the 12V rail(s) responsible for the GPU portion of power.

I would get this one:

I think more than enough lol. If you want to SLI that, get a 750-850 watt psu. If you just want a single card, get 650 watts, unless that 700 is on sale or on a good deal.

Thanks for the explanation, will search for a better PSU. Can you recommend any? running an i5'2500k, asus sabertooth z77, and a gigabyte gtx 680.
