  1. 1.0 1.1   Light-blue background denotes control signals.
  2. 2.0 2.1   Pins only present in 24-pin connector.
  3. In the 20-pin connector, pins 13–21 are numbered 11–20.
  4. Supplies +3.3 V power and also has a second low-current wire for remote sensing.[1]
  5. A control signal; it is pulled up to +5 V by the PSU, and must be driven low to turn on the PSU.
  6. A control signal; it is low when other outputs have not yet reached, or are about to leave, correct voltages.
  7. Formerly −5 V (  white wire), absent in current power supplies; it was optional in ATX and ATX12V ver. 1.2, and deleted from ver. 1.3.
