BFG GTX 275 OC Tri-SLI Power Consumption?

I'm trying to figure out if I'm gonna need a new power supply for a Tri-SLI setup with these cards.

Is there some kind of way to calculate it or is it just obvious that I will :pt1cable: .


Card- BFG GTX 275 OC - LINK

PSU - Corsair TX650 650W - LINK

Here is the rest of my build.

EVGA X58 SLI LE mobo
i7 920 D0 @ 3.6Ghz
6GB OCZ Gold DDR3 1600Mhz (3x2GB)
HAF 932 (Not sure if the fans take up noticable wattage)
x1 - OCZ Agilty 2 SSD 60GB
x1 - Seagate Barracuda 1TB
x1 - WD Green 1TB
x1 - WD Green 2TB
x1 - Lite-on Bluray Drive

Thanks.
