I'm currently using a http://pcpartpicker.com/part/ocz-power-supply-ocz750fty
. It's semi-modular(meaning that only the motherboard power cable is hard wired, all other connections are modular) and has a decent wattage rating for the price. It also has a nice red glow that I think will look good with your setup. It is also a tier 2 psu, so quality isn't an issue either.
