A power supply circuit module and a power supply judgment method thereof are provided. A power supply circuit supplies power to an electronic device coupled to the power supply circuit module. A plugging detection circuit detects the connection state of the electronic device. A judgment circuit switches the electronic device to connect to a first signal channel or a second signal channel in response to whether the electronic device provides device information of the electronic device within a preset time since the electronic device is coupled to the power supply circuit module. The power supply judgment method of the invention automatically sets signal channel configurations corresponding to different external devices, thereby greatly improving the convenience of use.
