Hey guys, in the near future I plan on building a pc for gaming, but on a low budget. I plan on getting an AMD FX-6300 with 8gbs of RAM and a 2GB DDR5 HIS Radeon HD 7850 and I need to know how much power I will need to support these components with room for future upgrades. I was looking at a 500W PSU earlier, but not sure if that is enough.
