2-5 Connector and Jumper Settings
Connectors are used to link the system board with other parts of the system,
including the power supply, the keyboard, and the various controllers on the front
panel of the system case.
The power supply connector is the last connection to be made while
installing a motherboard. Before connecting the power supply, please make
sure it is not connected to the power source.
All cables are security-proof
PW 1 (u-ATX Power Supply Connector):
The power cord leading from the system's power supply to the external power
source must be the very last part connected when assembling a system. The u-ATX
power supply provides a single 20-pin connector interface, which incorporates
st/-5V, +/-12V, optional 3.3V and Soft-power signals. The soft-power
signal, a 5V trickle supply is continuously supplied when AC power is available.
When the system is in the Soft-Off mode, this trickle supply maintains the system in
its minimum power state.
