ATX V2.3 / EPS12V V2.92 both define that the PSU has to use remote sensing to compensate cable drops on the 3.3V line. Because of this there is an additional brown cable crimped together with the orange cable either to pin 13 (ATX) or pin 1 (EPS12V). 14 -12V Blue -12 VDC 15 COM Black Ground 16 /PS_ON Green Power Supply On (active low).
