just like anything in the world..You get what you pay for. There are some standard PSUs that work fine and they will handle about anything you can throw at them.
use this to figure what size for your requirements and then just have to figure out a decent brand to go with. http://www.jscustompcs.com/power_supply/Power_Supply_Calculator.php?cmd=AMD
Unless you just want to have some bragging rights stay away from paying for a name.
