Is my POWERSUPPLY big enough for 6970 crossfire?

[pierogi210]

I own a COOLER MASTER Silent Pro M600 RS-600-AMBA-D3 600W ATX12V V2.3 SLI Certified CrossFire Ready 80 PLUS Bronze Certified Modular Active PFC Power Supply. I'm using it witha sabertooth 990fx with phenom 2 1100T, amd 6970, SSD, and 2 external HD. I want to add another 6970 to create crossfire. Will this power supply be able to handle that load? or will i need to buy a higher more powerful PS?

No, it is not powerful enough. You should be looking at a 900W+ power supply for a hex core 1100T and a pair of 6970's.
