2-7 Connector and Jumper Settings
Connectors are used to link the system board with other parts of the system, including
power supply, 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.
CN23 / 22 (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 standard +/-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 )
Blinking LED in Suspend Mode:
While in Suspend mode, the LED light on the front panel of your computer will flash.
Suspend mode is entered by pressing the Green Override Power Button on your ATX
case, or by enabling the Power Management and Suspend Mode options in BIOS's
Power Management menu. (See section 3.5 )
Poly-fuse Over Current Protection:
The poly-fuse protects the system from dangerous voltages that the system might be
exposed to via keyboards or USB connectors. In case of such an exposure, the
poly-fuse will immediately be disconnected from the circuit just like a normal fuse.
