ATX Power Connector

Pinout

Please note that this connector's pins are numbered oddly - not in the normal manner Instead it is numbered like the odd-ball Sub-d connector. Probably someone who had not laid out many PCBs did this. (A normal approach would have been to number it counterclockwise looking at the sockets or clockwise looking at the pins)

2 +3.3Vdc Orange
