Can I run SLI EVGA 670 4GB SC+ on CM GX 650W?

Was wondering if I will need to upgrade my psu or should I be fine?(don't feel like doing cable management again).

Is there anyone out there that knows if this PSU will go with two 670's? I read some forums that 670's will run on 650 if its good. Well can anybody tell me if cm 650 will do the job?

Thanks in advance,

or should i sell 670 and get 780?

Well they are 170w cards just like the 560Ti's are and I was running SLi'd 560Ti's on an old Corsair HX620w, so I would be inclined to give it a go.
