I have an Intel i7-4771 CPU @ 3.50Ghz with 16Gb ram, An ASUS H87-PRO motherboard, a GeForce GTX 650 Ti BOOST and 700 wattage of power. How much would wattage would I need if I were to replace the 650 with a 970? Is a 700 Watt power supply enough or would I face issues with that?

i recommend getting a gold 750 power supply so you will have room for another one, but you wont need more than 500watts (recommend getting one with gold "certificate" because thesehave the best power efficiency) :)

The GTX 970 need only a quality 500W PSU that can produce 28Amps on its +12V rail, for it to function properly. So consider this quality 550W PSU that can deliver 45Amps on its +12V rail, which is more than enough to power your entire rig:
