That should work just fine.

You could probably use a lower wattage power supply - my i7 has a 400 watt PSU (came prebuilt from dell) with a 4850 gfx card but its relatively low powered. I would go with a 650watt as minimum nowadays but that 850watt powersupply has a lot of room for upgrading later. You could easily add a second graphics card further down for the line. Corsair is a good brand too.

The PSU that magaman598 is very good but fairly too powerful in terms of Watt. As Yukka mentioned you may get another one with lower wattage but you need to know what type of graphic card you will be using and if they will be crossfire or not.

Actually, when it comes to PSUs you actually want to pay attention to the +12V Rail because everything in your computer runs off of said +12V Rail. So, in other words, you can have say, a 400W SLI/Crossfire certified PSU with maybe... 40-50 Amps on the +12V Rail. That's more than enough for two GPUs, although, finding a 400W PSU with a massive 40-50 Amp +12V Rail is highly unlikely.

I'm personally running a Corsair 650W Modular PSU and I'm loving it.

Not worth it imo, corsair 550w.
CORSAIR CMPSU-550VX 550W ATX12V V2.2 SLI Ready CrossFire Ready 80 PLUS Certified Active PFC Compatible with Core i7 Power Supply
Also RAM is pretty random too, with the x58, you should just get a 6(3x2)gb instead.

The 550 should make the cut, but I'd vote for the 650TX for some more headroom.
