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 and unstable because of insufficient
electricity. A minimum power of 300W is recommend for a fully-configured system.
