Can my current PSU handle crossfire?

[Tim]

If I were to add a second HD 6950 and go crossfire, can my PSU handle it or do I need a new one?

This is my current setup.

Silverstone ST75F 750 watt modular PSU.
Intel i5-760 (running at 3.4 ghz).
Corsair H50 cooler with 2 fans in push/pull.
Gigabyte P55A-UD3 motherboard.
8gb (2x4) G Skill DDR3-1600 (running at 1600mhz).
Sapphire HD 6950 2gb (unlocked shaders, 840mhz core, 1275mhz ram).
2 Intel X25-v 40gb SSD's.
Samsung F3 1TB HDD.
LG blu-ray reader/DVD burner combo drive.
1 120mm fan in the front of the case for air intake.
1 250mm fan on the side panel for air intake.
All fans (4 total) connected to a Zalman ZM-MFC1 plus 6 fan controller.

Your spec 12V1@18A,+12V2@18A,+12V3@18A,+12V4@18A
All you have do is read the total +12volt on ps case found it on line.
Looks like the specs, are a little over rated
I got 2 5870 on a 60A single line 750ps

You will have no problems at all with cf.
