I have recently gotten a new video card, an ati 3850 agp, and my old 250w power supply could not handle the load. So I purchased a 500w ozc ps, however after I installed it my computer would not boot past the POST screen. It would not even power a very basic configuration of the motherboard, video card and hard drive. So I sent it back and ordered a Cooler Master 500w power supply and it did the same thing, so I am starting to think it is not the power supplys. My motherboard is from 2002 and the rest of my computer is older as well, is there compatabilty issues between old parts and a new ps? If so which power supply is recommended for my system?
