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 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. The minimum recommend power

is 300W for a fully-configured system.

20-pin power cable

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.

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.
