I assume you have a whole system in there as well and it's not just the 780. But yes to both, you may want 650 if you want more headroom for overclocking or whatever. If you have a Microcenter nearby you, I would recommend this PSU. Made by Corsair, 650 watts, semi-modular, bronze rated, and after the rebate only $50.
