Installing the Motherboard
Connecting Case Components

necting the motherboard components. Refer to the following:
1 Connect the CPU cooling fan cable to CPU_FAN1.
2 Connect the case speaker cable to SPK1.
3 Connect the system cooling fan connector to SYS_FAN1.
4 Connect the case switches and indicator LEDs to the PANEL1.
5 Connect the standard power supply connector to PWR1.

Connecting 20/24-pin power cable
Users please note that the 20-pin and 24-pin power cables can both be connected
to the ATX_POWER connector. With the 20-pin power cable, just align the 20-
pin power cable with the pin 1 of the ATX_POWER connector. However, using
20-pin power cable may cause the system to become unbootable or unstable
because of insufficient electricity. A minimum power of 300W is recommended
for a fully-configured system.

24-pin power cable
With ATX v2.x power supply, users please note
that when installing 24-pin power cable, the
latches of power cable and the ATX_POWER
match perfectly.
With ATX v1.x power supply, users please note
that when installing 20-pin power cable, the
latche of power cable falls on the left side of
the ATX_POWER connector latch, just as the
picture shows.
