A power integration module includes a first input connector, a second input connector, an output connector, a switch unit, a determining unit. The first input connector and the second input connector are electrically connected to a first power supply and a second power supply of a power supply module. The output connector is electrically connected to an electrical load. The switch unit is coupled between the first input connector, the second input connector and the output connector. When the switch unit is turned on, the first input power supply and the second input power supply are integrated in parallel and outputted to the output connector to the electrical load. Moreover, an electronic device with a plurality of power integration modules is provided. Thus, the wrong connection is prevented and the condition that the power supplies of different electrical parameters are connected in parallel is avoided.
