I'm currently running a system which contains a GIGABYTE GA-990FXA-UD3 a single sapphire 7950 and a FX-8150 with no OC my question is will my Antec EarthWatts EA-650 GREEN 650W support a second 7950 in crossfire? thats pretty much it XD

Yes it will size wise but lacking 2 x PCIe power connectors. I would suggest an upgrade to 750watts.

No simply because it doesn't have enough PCI-E Connectors, your Power Supply only has 2 x 6+2 Pin PCI-E, a 7950 crossfire needs 4. Besides a crossfire of those GPU's needs like 750 watts.

Although 700watts is recommended by manufacturers it is based on generic PSU's.
Total system load with two HD7970 less than 650watts http://www.anandtech.com/show/5805/nvidia-geforce-gtx-6...
2x7950 consume between 100-150watts less in crossfire http://forums.atomicmpc.com.au/index.php?showtopic=264
