Realistically, all you'd need is a 300W power supply. That XCLIO Goodpower 500W is a good choice though. =]

Any reason you going with a Micro-ATX form case..?

 

Get better RAM IMO.

I would recommend a decent 400-450w PSU.

A good rule of thumb would be to purchase a PSU according to the requirements of the graphics card. The 8500 will be fine with a 450-500W PSU.
