I would suggest the Corsair CX series. Very reliable and if you're okay with bronze this one is very reasonably priced.

CX series are not reliable at all, have fluctuating power outputs, built with cheap parts and have a high failure rate when under stress. They should generally be avoided. The CXM series on the other hand are very good PSU's.
Personally i would say go with an EVGA SuperNOVA (G2+ G2+ if you can afford one), very reliable with high quality parts. Mine has powered 2 different machines over the course of 4 years and is still going strong.
