Good thing you pointed it out, because it's not, and it does make a little difference. It has 4x6pin, but 4870X2s use a 6+2pin along with a 6pin. So you'd need a PSU with at least 4x6+2pin.

So here's another suggestion that will suite your needs for the future:
Newegg.com - XIGMATEK MC NRP-MC851 850W ATX12V Ver.2.2 / EPS12V Ver. 2.92 SLI Ready CrossFire Ready 80 PLUS Certified Modular Active PFC Power Supply - Power Supplies
It has 2x6pin and 2x6+2pin.

It has enough power but not the right connectors. It has four 6-pin PCI-E connectors.

You need a psu with at least two 8-pin and two 6-pin PCI-E connectors if you want to add another 4870x2.
This one has four 6+2-pin PCI-E connectors:
Newegg.com - CORSAIR CMPSU-850TX 850W ATX12V 2.2 / EPS12V 2.91 SLI Ready CrossFire Ready Active PFC Power Supply - Power Supplies

Edit: Ah, Xan beat me.

The one that gt7 suggested is better, but I remember you saying that you wanted a modular, so that's why I suggested the Xigmatek.

But on the other hand, if you planned on adding another HD4870X2, and maybe other stuff in the future, you'd most likely be using up most of the PSU cables. Therefore, not really a need for a modular.

Even with modular, there are still lots of cables around so I wouldn't base your choice on that. Get a good PSU quality wise. Get this one Newegg.com - PC Power & Cooling S75QB 750W ATX12V / EPS12V SLI NVIDIA SLI Certified (Dual 8800 GTX and below) CrossFire Ready 80 PLUS Certified Active PFC Power Supply - Power Supplies

Oh and upgrading to quadfire in a year or 2 with 2x 4870x2's would be pointless. Quadfire isn't very effective and so you won't see much performance boost. Just get a new card when the 4870x2 isn't cutting it for you anymore.

Case looks kinda cheap, why not look at the Coolermaster HAF 932? I just got one, its got alot of room, and the fans are huge, which means awesome airflow. Cooler Master HAF 932 Full Tower Black Case RC-932-KKN1-GP at TigerDirect.com
And its rly not that pricey for a full-tower case, I fit my liquid cooling system in there smoothly.

I would save 197.97 more bucks.
Cpu: Core i7 920
Case: Antec 902
PSU: Corsair 620HX
RAM: Corsair 6GB dominator 1600mhz

total 797.97

no point to cut corners halfway through a build.
