Well can you do it? Say I have a 500W ATX PSU, but I don't have enough 4 pin molex connectors. Well for one I should probably get a new PSU, or get a couple of Y-Spliters. But could I use 2 PSUs. So could I power all of my core components with the 500W PSU (e.g. Mobo, CPU...). And then for DVD/CD-ROM Drives use an old AT PSU. Oh yeah it could also power my molex fans right? Would that work?
