2 Connect the system cooling fan connectors to SYSFAN2/3.
3 Connect the connector for graphics interface to ATX4P1.
4 Connect the case switches and indicator LEDs to the PANEL1.

Connecting 20/24-pin power cable
Users please note that the 20-pin and 24-pin power cables can both be con-
nected to the ATX1 connector. With the 20-pin power cable, just align the 20-
pin power cable with the pin 1 of the ATX1 connector. However, using 20-pin
power cable may cause the system to become unbootable or unstable because of
insufficient electricity.

the latche of power cable falls on the left

note that when installing 24-pin power cable,
