The POE integrated power supply consumption machine comprises an RJ45 network interface which is arranged on a consumption machine body. The RJ45 network interface is respectively connected with a network data signal circuit and a power supply management circuit. The power supply management circuit comprises a bridge type rectification filter circuit, a power supply switching circuit and a DC/DC processing circuit. Rectification and filtering are performed by the rectification filter circuit on a voltage signal inputted via the RJ45 network interface, and then the voltage signal is transmitted to the DC/DC processing circuit via the power supply switching circuit. After voltage reduction and voltage stabilization are performed on the voltage signal by the DC/DC processing circuit, 5VDC voltage is outputted to the network data signal circuit.
