When using ATX power, it is
necessary to use a 24pin-to-
4pin power cable to connect
between the 24pin power
connector of PSU and the
ATX12V2 connector on the
motherboard for power supply
and signal communication.
For DC-IN 12V application,
it is not necessary to use this
ATX 4-PIN power connector.
*Caution: Misconnection between the
ATXPWR1 and the HDDPWR1 con-
nectors may permanently damage the
motherboard.
