I dont know how many boards you have used, but about all later Socket As had the 4 pin CPU connector, I have one right now a Abit KV7, and most 754s had the 24 pin power connector, unless you had a older AGP 754 board, there all kinds of 754s with 24 pin power connectors. I have a Gigabyte and DFI 754 that has a 24 pin connector and I have a Epox 939 that only has a 20 pin. So its not a rule, just because you had 1 that didnt does not mean that they all didnt!
