The invention discloses power supply equipment and a power supply system. The power supply equipment comprises a power input end, a recognition unit, a processing unit, a switch unit and an external interface, wherein the recognition unit is used for acquiring a partial pressure value of powered equipment in real time, determining the rising time duration of the partial pressure value of the powered equipment, and sending the rising time duration to the processing unit; the processing unit judges whether the rising time duration is within the preset time duration, if the rising time duration is within the preset time duration, determining the powered equipment as the POC equipment, and supplying power for the powered equipment through the switch unit by the power input end, if the rising time duration is not within the preset time duration, determining that the powered equipment is not the POC equipment, and not supplying power for the powered equipment. Since the difference between the rising time duration of the voltage value of the POC equipment and the rising time duration of the voltage value of the non-POC equipment is large, the power supply equipment acquires the partial voltage value of the powered equipment when in out of power-supply state to determine the rising time duration, thereby determining the type of the powered equipment; and a problem that the powered equipment is burnt due to the error type confirmation of the POC equipment type.
