As for the GPU 500W would be enough, But due to the AMD 8350 high power usege (up to 125W alone) a 600W 80 Plus PSU would be great and leave space for a CPU water cooler even like the H100i.
If youre planning for OC in the future you can use the 600W but a 700W and above will leave you space even for crossfire.
