that should be fine, i have a 560watt psu and it runs my 7870.

i would get another 4GB of ram thought.

NO. CM sells mostly near-junk PSUs, as review after review has shown. They are finally starting to improve (their new V-series is made by Seasonic), but they have so much dishonestly-labeled garbage out there that I cannot in good conscience recommend any of them.
A quality 500W PSU is enough, but not something from CM. A quick and easy choice would be a 500W Antec Earthwatts, but that may not be your best deal.
Skip the NON-MODULAR Corsair CX units (made with inferior capacitors), but the modular ones are also good, or a Seasonic 520W SII or MII or 550W GS.

500W (or greater) power supply with one 75W 6-pin PCI Express power connector recommended7

600W power supply (or greater) with four 75W 6-pin PCI Express power connectors recommended for AMD CrossFire™ technology.

Id consider a 600 watter in case CF is in your future.... not a big cost difference between 500 and 600

Id take the TX650 V2 .... make sure to avoid any with the M suffix or CX prefix.
