Watch the gpu, I would recommend getting a psu with at least 750w so that you can upgrade later, also make sure it is a good and reliable main brand, because 1. If it fails you'll have to rewire everything again. 2. Bad gpu's can ruin your parts and shorten their life.
3. Just make sure it's at least 750w that way you can upgrade parts of need be in the future without worrying to much about how much power the parts may use, thus allowing you to chose from a larger variety of parts. (Just a side note, USE a SURGE PROTECTOR, or a decent UPS system in case the power blinks it won't damage your pc and if your working on something and the power goes out, you should have time to save your game/work document.)
