Can this Power Supply handle it?
CORSAIR RM Series RM650 650W ATX12V v2.31 and EPS 2.92 80 PLUS GOLD Certified Full Modular Active PFC Power Supply

Yes, a 650 watt PSU will be sufficient to handle it.

GeForce GTX 770 - 42A and a 600W PSU minimum. So 650W PSU will be enough, but don't go with RM series, there are thermal issues with that series, and not that good.
