Hello,

I'm deciding between 650w and 750w PSU from Cooler Master GM Series Modular 80+ Bronze, both are single rail with 52 A and 62A output. I was wondering if 650w is enough for 980 ti G1 gaming which is very "hungry" i7 6700, 2-3 HDD's with dvd rom and a couple fans? or it should be better choice to go with 750w?

thanks.
