CMPSU 650TX sufficient?

I was wondering if my CMPSU-650TX would have enough juice to support crossfire.

My current build (for which my PSU has no problems):

Mobo:p 7P55D-E Pro
CPU: i7-870 lynnfield
Storage: Intel 80GB SSD + Seagate 500GB HDD sata 3.0 + Seagate 1.5TB HDD sata 6.0
Memory: 8GB Ripjaw
Cooling: Hyper 212 CPU Cooler with fan, 1x200mm top fan, 120mm side fan, 120mm front and back pannel fans.
Other: Scythe "Mesh" fan controller.
GPU: XFX Radeon HD5770

I just bought and installed a SECOND identical GPU, but realized XFX was too cheap to include a crossfire bridge.

Right now, both of my GPU are connected and my PSU still runs correctly.

I want to know if I'll lack power when I will add the crossfire bridge.

Thanks a lot!

If you want to objectively, accurately and scientifically determine what PSU power is required for your Vid card and PC in both watts and 12v rail amps., the forum Utility link below will show you how easy it is to calculate this information and objectively determine which PSUs are quality built, reliable PSUs that can meet your needs. Be advised that the available 12v rail amps. is just as important as the total PSU wattage. You need both to be correct.

The Corsair CMPSU-650TX, with its +12 Volt continuous current rating of 52 Amps, is more than enough for a system running two Radeon HD 5770 graphics cards in 2-way CrossFireX mode.
