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 that provided by CHAINTECH come with a security-proof.
PW 1 / 2 (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 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 Soft-Off mode, this trickle supply maintains the system in its minimum
power state.
The ATX 12V power supply has a new +12V (4-pin) and +5V / 3.3V (6-pin)
auxiliary power connector to enable the delivery of more +12 VDC and + 5/ 3.3V
VDC current to the motherboard.
Power-On By Modem:
While in Soft-Off state, if an external modem ring-up signal is detected, the system
will be activated and therefore can be remotely accessed. You may enable this
function in BIOS's Power Management Setup menu. (See section
3. 5
