Yes, but this PSU won't output 630W all the time. I'm not saying that this won't be enough, but it definitely won't give you much headroom for future upgrades, and after OCing, it's going to get near the limit. Generally, I'd say a 630W PSU is fine for this setup, but some other people actually have the right idea here in that you should get a branded PSU (granted, it needs to be the right one for it to actually be worth the money). You'd be better off going with this.
