I'm running two 650 gtx cards with a 1200W Power Supply and was wondering if I switch to dual 750 Ti's, will I need to improve my power supply as well?

No I wouldn't have thought so. The GTX 750 Ti uses about the same power as a vanilla GTX 650 (in real world tests, about 66 watts maximum per card for the reference design or a bit more for the OC models).  At this power level, they shouldn't even need a PCIe power connector.  Important to note that the GTX 750 Ti does not support SLI (nor do the GTX 650's actually).  A single GTX 770 or 780 would be my choice.  Alternatively you could SLI 2 x GTX 660's for similar money.

If that is a decent 1200 watt PSU, then you are in the realm of overkill for the sake of overkill. You don't need more than a 300 watt power supply to power a 750ti. 400w if you want a second one for PhysX.
