You may use the 20-pin ATX power supply as you like. If you’d like to use
the 20-pin ATX power supply, please plug your power supply along with
pin 1 & pin 13. There is also a foolproof design on pin 11, 12, 23 & 24 to
avoid wrong installation.
Important
Power supply of 350watts (and above) is highly recommended for system
stability.
