The new ATX power supply standard now is 24-pin, previously was 20-pin. The extra 4 pins are 3.3v and Ground. This is for the ATX POWER CONNECTOR, which has a detachable "square 4-pin" plug connector.
Now if you're talking about a SEPARATE square 4-pin connector with (usually) 2 black and 2 yellow wires, that has been around for years and that's for certain AMD and P4 CPU mobo's which require the special connector for their additional power requirements. It's usually next to the CPU socket. The PC won't boot without power going to that connector. -Clint God Bless Clint Hamilton, Owner http://OrpheusComputing.com ----- Original Message ----- From: "Larry" <> what is this plug small square 4 prong with 2 yellow and 2 black wires. it measures 12 volts. can this also be supplied from any yellow 12v lead?? larry ============= PCWorks Mailing List ================= Don't see your post?
