I was considering a Corsair VX 450. Supposed to have amazing power regulation. This board is old (although unused) so wan't a quality power supply to ensure no damage or pushing of ATX tolerances. Also would prefer modular
Any power supply will work. the p4 connector is for pentium 4 and up motherboards not p3 I have a 500w PSU with a cuv4x-d motherboard with 2 tualatin 1.4GHz overclocked to 1.8GHz and 4670 agp.Just remember that when you install windows you will need to install RIVA tuner to tell the VIA chipset to run at 4x mode otherwise it will be 2x even though you have it set to 4x in the BIOS it will read 2x in windows.
