An electric power steering system includes an electric power steering device. The electric power steering device includes an electric motor, a controller controlling the motor, and two power supply connectors that assist a steering operation of a vehicle. The electric power steering system also includes a first power supply supplying power to a first connector, a second power supply supplying power to a second connector and to other in-vehicle devices other than the electric power steering device, and a power switcher provided en route to the controller, to electrically connect the first power supply to the controller when power supply from the first power supply is normal, and to electrically connect the second power supply to the controller when the power supply from the first power supply is abnormal.
