I am most likely going to be building a desktop very soon and I want to know how my choices look for the parts.

I dont want to spend too much more than that so but I am wondering are any of the parts listed not the best for the price? or is there a better part for around the same price? Another note: I have no idea what power supply I will be needing. Is 650W more than what I need for this rig? Thanks in advance!
