well according to coolermasters own little calculator you will only need 620watt to power your current system. So I think it will work fine. but the issue is. Does you Power supply have an additional gpu power leads?

nope it has only 2 pcie 6+2,but i think it will do the trick with 2 molex to 6 pin

700 watts should be enough..

If you can go 750-850 if you want to add stuff later, better to have more and not need it than need it and not have it.
