The SeaSonic G Series 550-Watt at $80 will give you all the power you need for a single GPU system with an overclock. It's made by one of the best PSU companies out there. It's 80-plus Gold efficiency. It has 2 6+2 PCIe connectors. It is also modular which is great for smaller cases. It has a five-year warranty, so you now the company is backing a quality-built product. There are great reviews out there for this supply:

You don't want to build a great computer on a crappy PSU. The PSU affects every component in your system. I see it as among the most important components.

You could also go with the 520W Version and save $10

$10 savings, but add $6 for shipping (Amazon is free shipping). After the shipping charge it's about a $4 difference and the 520W version is not modular.

True enough. Unless a person happens to be a shoprunner member, the 550 would be a better option :-)
