I was wondering if 550W is going to be enough for this build or will I have to step up to something like the Seasonic 620W? I assume that it is I just want to make sure. I am also planning on overclocking the CPU and GPU.

For a single GPU 550W is plenty. If you want to add a second 760 later on you will want a 750W or higher.

Yes this was my thinking. Personally not a fan of SLI so i would be replacing it with a 780 or something like that. But I would still have to go up to a 600W. How does this compare to something made by Seasonic or XFX? Newegg

Those Corsair CX power supplies are actually made by Channel Well and not really known for being the highest quality. I've personally had to replace a couple of CX430s. Corsair actually rebrands a lot of Seasonic PSUs, mainly the TX, HX, and AX series. I'd stick with the Seasonic to be honest.
