A 750W unit from corsair will handle them just fine, they need less power than the 5850 which you can run two of on a 750W unit easily, you wont have a problem with 2 6850s on a good 750W unit like you have.

Thanks! I had another question. My motherboard supports Crossfire but not when running SATA 3 and USB 3 do I have to turn them off manually or does it do it for me?? Are there any additional options I have to change to enable Crossfire??

It should turn them off automatically and let you do Crossfire, however your motherboard manual should outline the process and any hurdles you might have to face.
