I am upgrading my pc and i need to know how big off a psu i need. Im planning on having 6-8gb ram, a geforce gt 730 2gb 128bit, and possibly (im pretty sure not) a 500gb hard drive. I know its not a wonderful build (if you have any suggestions for a better pci express 2.0 x16 video card let me know) but i want to have a power supply thats cheap as possible, efficient, gonna last me, and gonna be stable. Im planning on running games like mw2, bo2, cod4 and csgo from medium to high settings without rugged edges. i heard a 500w is good, but I would like to spend under $60, and im sure its possible if I use a site like tigerdirect.com etc.
