2.7 Connecting the Power supply cable

The ATX power connector is keyed for proper insertion. There are two
connectors for 4-pin and 24-pin ATX power cable. The plastic clip on
the power connector should lock over the plastic tab on the
motherboard power connector.
Connecting 20/24-pin power cable
Users please note that the 20-pin and 24-pin power cables can
both be connected 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 insuffi-
cient electricity.
