necting the motherboard components. Refer to the following:

Connecting 20/24-pin power cable
User 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.
