Solution
Well it will run your gpu but also might catch fire in your pc, so that's something to think about. You really should try to get a name brand 80+ bronze psu

Edit: trust the expert ^

Yeah, he probably has a entry lever GPU which can run even on a cheap 500W PSU. But It would be good if we can give him an advice to get a better PSU, in case the current one is generic.

really? Should i worry about any damage?

 
A name brand 80+ bronze is the minimum that will ever be recommended. Generic PSUs are not built well and while not as common as people make it out to be they can catch fire, power surge, etc which could damage every other component. PSUs aren't even very expensive either so it's an upgrade you should strongly consider.

It's hard to tell, but I wouldn't recommend using it for a longer period. Save money in the meantime and buy a better one.

However, the good thing is that GTX 650 has a TDP of only 64W. So, 64W/12V = 5.3A. I'd say you picked the perfect card for your PSU, but this shouldn't encourage you. Your PSU can still damage your PC.

Then look for brands like Antec, Seasonic, Corsair, XFX with 80+ bronze certification and at least 450W.
