Anyways. I've got a question. I have a relatively older system. I'm using an old Thermaletake Silent PurePower 480W PSU. If I can recall correctly, it has a single 12v Rail @ 18A. My question is, with the new parts coming in, am I going to new to upgrade my PSU? Am I in danger of baking my machine into oblivion? I have a x1950 Pro PCI-E which i'll still be using.. I'm just concerned. Advice?
