I bought a Gigabyte SUPERB 460w PSU as a replacement for a mate's PSU (it's a P4 based box), and it seems that the ATX connector on the new PSU has 4 pins too many and is too large to fit in the socket on the motherboard. It's not the type where you can snap off the extra bit either 
I am keeping the PSU as a spare anyway, but can someone suggest a cheapo replacement PSU that has the "old" type ATX plug and will fit his mobo?
Thanks muchly!
