Hi i was curious if a Corsair RM650 would be able to safely support an i7 6700k and a MSI GTX 1070 GAMING X? I am not sure if i am going to be able to afford a new Power Supply and If my budget permits i was going to probably go with an EVGA SuperNOVA P2 850w. Would it be fine if powered by maybe A 750w PSU and would i be able to do a slight CPU overclock? Sorry for all the questions but I just want to make sure I get all the information i can before i make a purchase.
