Does the OCZ Fatal1ty 550w PSU have enough power for Crossfire 5770's?

Hello everyone,
I have a OCZ Fatal1ty 550w power supply (http://www.newegg.com/Product/Product.aspx?Item=N82E16817341022&Tpk=ocz%20550w) and I was thinking about crossfiring my 5770.
Here are my specs:
ASUS p6t (not deluxe) motherboard
I7-930 OC to 3.5GHz, 1.13v (can be un-overclocked if needed)
Sapphire Vapor-X 5770 (OC to 95/1325, again, can be un-overclocked)
WD Caviar Black 1TB 7200RPM Hard drive
Antec 600 case (120mm red tricool, 200mm blue tricool, 120mm blue twocool fan)
LG WH10LSK Blu-Ray burner
Cooler Master Hyper 212 plus (one fan)
Corsair XMS3 TR3X6G1600C9 6GB RAM
OCZ OCZ550FTY 550w ATX12V PSU

I wanted to add an HIS ICEQ Radeon 5770 to this http://www.newegg.com/Product/Product.aspx?Item=N82E16814161333&cm_re=his_iceq_radeon_hd_5770-_-14-161-333-_-Product.

Will this power supply be enough for the upgrade or will I need to get a higher rated PSU?
EDIT: I may add another 6gb of Corsair RAM (same ones) maybe, but probably not :)

Please help!!
Thanks

  4. AMD are always going to cover themselves but knowing the rest of your system I think you'll be fine.
  5. ^The red pill or the blue pill..
  6. Thanks to everyone!!! I now have crossfire :D
    Newegg ships FAST lol everythings rock solid and it doesn't hurt that I can make all my games (bfbc2, nfs shift) have 8xAA and max settings at 1080p :)
  7. I know what you're thinking, 'cause right now I'm thinking the same thing.
    Actually, I've been thinking it ever since I got here:

    Why oh why didn't I take the BLUE pill?
