Hello xtremegamer2da-max;

Any high quality 700W~750W PSU will have plenty of power.

Any plans for 2-way Quad Crossfire?

The Radeon HD 7990's rumored Maximum Board Power is 300 Watts which would make its power requirements more like the Radeon HD 6970 which has a Maximum Board Power of 300 Watts.

About 300 watts for the graphics card and about 300 watts for the rest of your parts.
That's with the CPU OC'd to 4.6Ghz and a few extra parts not actually on your list (USB device, etc). And with all the parts drawing full power at the same time (which almost never happens).
