Though this motherboard provides 24-pin ATX power connector,
it can still work if you adopt a traditional 20-pin ATX power supply.
To use the 20-pin ATX power supply, please plug your power
supply along with Pin 1 and Pin 13.
ATX 12V Power Connector
(8-pin ATX12V1)
(see p.13 No. 3)
Though this motherboard provides 8-pin ATX 12V power
connector, it can still work if you adopt a traditional 4-pin ATX
12V power supply. To use the 4-pin ATX power supply, please
plug your power supply along with Pin 1 and Pin 5.
