The three shaded pins (8, 13, and 16) are control signals, not power. "Power On" is pulled up to +5V by the PSU, and must be driven low to turn on the PSU. "Power good" is low when other outputs have not yet reached, or are about to leave, correct voltages. The "+3.3 V sense" line is for remote sensing.[1] | |||||
Pin 20 used to provide −5VDC (white wire) in ATX and ATX12V versions up to 1.2. It is optional in version 1.2, and missing in ver. 1.3 and up. | |||||
The right-hand pins are numbered 11 through 20 in the 20-pin version. |
