Supply for crossfire and clock

[Guest]

Hello guys, so my build will look something like this:

CPU: i5 2500k + hyper 212 cooled
GPU: 2x 7950s Sapphire OC
RAM: 2x2 DDR3 A-DATA 1600G 1600Ghz
MOBO: AsRock Extream 4
HDD: Hitachi Sata III 500gb

So what supply should i get for this rig. And i want to overclock too. So far i have chosen Seasonic SSR-650rm 650W GOLD which is with 54A 12V rail (this supply is similar to the XFX 650W but i cant buy this one from my country which is Bulgaria). So is this enough or should i get something bigger.

I don't know if 650w is enough for 2x GPUs and OC'ed CPU.
Try putting that into:

for a rough idea.
