ATX/ATX12V Auxiliary Power Connector
The ATX/ATX12V Auxiliary Power Connector, shown in Table 26-13, is recommended for configurations that require more than 18A of +3.3VDC or more than 24A of +5VDC. This is an inline 6-pin connector with Pin 6 keyed. The motherboard connector is a Molex inline 6-pin 15-48-0412 header or equivalent. The power supply connector is a Molex 90331-0010 or equivalent. All wires are 16 AWG. Wire colors are standard. Few inexpensive power supplies provide this connector, but it is present on some better power supplies. With the shift to ATX12V and 12V VRMs, the importance of this connector is decreasing. Few motherboards include this connector.
