First off, Raidmax = no. Doesn't matter if it's 1000W, no. Read my sig. I'm running the exact same setup on a quality 450W PSU. I haven't had any issues.
Unfortunately this PSU only has one 6-pin connector. You want to find one with at least two. That way you can upgrade your Video Card to a higher end model and not have to swap PSU's.
Edit: The Corsair CX600 V2
is a solid PSU, has two 6+2-pin connectors and has enough headroom for future upgrades. But a quality 430W or 450W will suffice.
