Abstract: This application discloses a power supply management system, and a power supply management method and apparatus applied to the system. The system includes a power sourcing equipment, a powered device, and a power supply line. The power sourcing equipment sends a second voltage to the powered device to determine a first voltage. The first voltage is a maximum power supply voltage agreed on by the power sourcing equipment and the powered device. The power sourcing equipment supplies power to the powered device based on the first voltage. In this application, the power sourcing equipment supplies power to the powered device based on the maximum power supply voltage that can be supported by the powered device, so that a loss on the power supply line is reduced.
