i would recommend a 550watt seasonic or corsair psu (the cx series is not great, but will work if you don't wanna spend more) for that build

Corsair hx650 if u have the money that is a quality psu and will leave room for upgrades. But a 500 watt psu should be fine if your on a budget.

Personally i think the hx 650 really only has one use, and that is for dual gpu cards like the 690 or 7990. otherwise it is just slightly underpowered for sli, and overpowered and overpriced for a single gpu. If you are looking to sli in the future, I'd recommend no less than an 800 watt psu (you can go lower, but it's always nice for breathing room) remember to look at amperage on the 12v rails. the 770 requires that you have no less than 32 amps on the 12v rail that is powering it, and if you are an overclocker, you may want to find a psu with at least 40 amps on the 12v rail (same applies if you want a second one, but just double the 12v rail requirements so that you either have 1 60 or higher amp 12v rail, or 2 32 amp 12v rails)

yes but i trust corsair and the hx is very good quality i have had mine for years. Although i do wish they made a 550 watt version.
