I know a little about PSU.

I look for the top 3 maker on PSU. ( Super Flower/Seasonic/Delta)

Well, that 650W EVGA SuperNOVA G2 is going to be impossible to beat. It will have all the power that you could ever need for that system with two 285s in it (at stock with the overclocked 4690K), and it's extremely high-end.
I did a little more research on the sapphire R9 285. They are about 190 watts each. To run HEAVEN Benchmarks at 1050/1500. I need 10% power limit. So that means about 220 watts per card. That leaves me about 210 watts on a 650 watts PSU for the rest of the rig. A 650 watts should be enough for 2 R9 285 CF.
Thanx TwoCables.

You're welcome. Know too that the 650W G2 is an extremely high-end PSU that can deliver 650W 24/7 if it's ever needed. So, 650W isn't its absolutely limit. That's what it's designed to deliver.
