I am building an old Pentium 1 PC Socket 7 for my Tech Class. I have everything but a Power supply it is for sure an ATX motherboard with 3 IED's, 2 PCI's, 3 SIMM RAM Slots, and a AGP Slot. It seems to be a 20pin Power Connector. Would I be able to hook in a modern Power Supply? (If you need a picture I can send one)

Kind of hard to tell but I will try to give as much information as possible. I did search into google but couldn't really find anything. The bios is an AMI, there is a chip on here that says SIS 5595 and maybe a heatsink that says PC100 SIS 530.
