5.1 Power Supply
5.1.1 ATX Connector and Behavior Control
The COM Express® Reference Carrier Type 6 power supply follows the ATX 2.x specification and the baseboard should
be supplied by connecting an ATX PSU with 20pin ATX (J58) and 8pin ATX_12V (J59) supply cable in correct
orientation. The 8pin ATX_12V connector mainly supplies power to the module and allows powering the module
directly in specified wide range power input. The module additionally is supplied with 5V standby voltage. Single
supply mode is controlled by J85, and then the 20pin ATX connector J58 is not necessary to connect.
J26 overrides the PS_ON# signal in ATX powered mode.
