I already have a Corsair CX 500 watt power supply. Will it be able to handle SLI for 2 GTX 650 ti Boosts? I am not going for a single card setup, as it is more convenient at this time.

no the 12v rail on the 500w unit would be fine for one card but not two you need a 750w unit to be safe.

I'm running Sli'd 660Ti's on a 620w PSU and the 650Ti Boosts would consume about 30w less so a 750w is not needed.

I recently got a 760 instead. I would probably need a new psu to put a 760 in sli, right?

Yes, the 760's are 170w GPU's so a GOOD 650w or 700w + PSU will be required. I have had 2 170w cards running on a Corsair HX620w PSU but I don't think you can get them anymore.
