JCOM1: Serial Port Connector

The COM connector can provide one serial port via an optional COM port cable.

ATXPWR1, JATXPWR1~2: Power Connectors

With the use of the power connector, the power supply can provide enough stable power to
all the components on the motherboard. Before connecting the power connector, make sure
the power supply is turned off and all devices are properly installed.
24PIN for motherboard power supply.
8PIN for CPU power supply.
Important
• It is recommended that a power supply that can withstand high power consumption be
used (at least 500W). If a power supply is used that does not provide the required power,
the result can lead to an unstable or unbootable system.
