Hey, I have made a PC part list, and I was talking to my friend and he said I need at least a 500W PSU. But I wanna do a cheap build and the 430W PSU I have now is what for the price. But I wanna know if I need a 500W+ PSU?
It is plenty. You could even throw in a much more powerful GPU, like say a GTX 760 or R9 270X and be just fine. Plus, you only have an Athlon CPU. You won't be dropping a GTX 780 in there or anything so power wise you'll be fine even if you decide to upgrade in the future.
