Default Re: 850W Enough for GTX 480 SLI?

Hey I was wondering If my current Corsair 850HX PSU could support this system:

i7-950
500GB HDD
Asus Rampage Gene III Motherboard
6GB Triple Channel RAM
GTX 480 SLI
Corsair A50 CPU Cooling

Any help would be appreciated!

Here's a link to my PSU

Corsair Professional Series HX850 Modular 850 Watt Power Supply (CMPSU-850HX) | Canada Computers

Edit: I also plan on adding a 64GB SDD.

850w is a lot so I'd say yes.

Newegg has a nice power supply calculator on their that I use when I do my builds: Newegg.com - Recommended Power Supply Calculator.

Had to do a little guesswork with the equipment you posted, assumed you're running 3 - 2gig ram dimms, a 7200 rpm hdd, and 1 optical drive. I'm getting 650w as the minimum reccomended power requirements for your system.

I got 945W with that calculator. I used 3 sticks of 2GB DDR3 RAM, a 7200 rpm hdd and no optical drive. How did you get 650W? O.o

Btw, thanks for your reply! ^.^
