i am planning to get one of the follwing:
Evga supernova NEX650g 80plus gold fully modular-89$
Evga supernova 750 b2 bronze semi modular-80$
Corsair CX750M semi modular bronze-74$
i was thinking that i should get quality efficientcy over more wattage but i might be wrong, just need some tips
since i have two gtx 660 i wanna sli those, right now im only running one 660 on my 450 cooler master bronze, even though the EVGA 650 gold is not 750 it still should be more than enough right?
