Figure 26. Auxiliary Power Output Connector
The D955XCS board includes a male 1x4 power connector that can be used to provide power
for internal chassis lighting or additional fans using less that 1.5 A. The 1x4 connector is off by
default. You can turn on/off the connector from within the BIOS Setup program under
Advanced Peripheral Configuration Auxiliary Power.
Use of this connector requires an ATX12V power supply with a 24-pin (2x12) main power cable.
If a power supply with a 20-pin (2x10) main power cable is used, the auxiliary power output
connector may not function. The connector circuitry includes overcurrent protection components
that limit the current draw to a maximum of 1.5 A.
