The three shaded pins (8, 13, and 16) are data signals, not power. "Power On" is used to power on the PSU (except the +5 standby connection). This connection is left open or held high (+5v) to keep the PSU off. It is grounded or held low to turn on the PSU. If the PSU is capable of handling the current load, "Power good" will be held high. If the PSU cannot handle the current load or input voltages are too low, this line will be held low. The "+3.3 V sense" line is used to more accurately control the +3.3 line when under load.

Pin 20 used to provide −5VDC (white wire) in ATX and ATX12V versions 1.2 and earlier. Version 1.2 allowed the omission of this pin,and versions 1.3 and beyond prohibited this pin. | |||||
The right-hand pins are numbered 11 through 20 in the 20-pin version. |
