Your psu is mainly going to be based on your graphics card requirements. Most psu options are going to be whether it supports crossfire/sli or if the harness is modular or not. Your really going to be struggling in the near future with a graphics card in that price range in comparison to the rest of your build. All of those components will work fine with each other but there are things to consider.
1. If you are planning on overclocking any components now or in the future.
2. If you are planning on running crossfire/sli (2 vid cards) in the future.
If you aren't planning on overclocking or running multiple monitor setups then you can save some money on the mobo, cpu, psu, and you definately won't need a cpu cooler.
