I'm in the process of upgrading my computer and I don't know how large of a powersupply I will need, the build as is: Athlon II x4 860k - Radeon R9 270x 4gb - 8gb system ram (possibly up to 16 later) - 1 Terabyte HDD - Asus a558 m-e motherboard - 2 case fans, just one being 120mm, and the stock cpu cooler.

The Asus website said I needed around 600-650 watts of power, but as of now with the processor being the only part not currently in the case, my computer runs with a 525 watt psu. Any help or links would be greatly appreciated!

Edit: I realized after posting that I never gave what my current processor is, atm I have an AMD a6-6400k processor with everything else listed, the processor would be the only change, everything else is already in the case and runs with a 525 watt psu.
