1. A movable barrier operator system comprising:
a motor configured to be coupled to a movable barrier and move the movable barrier between open and closed positions, the motor having a power rating indicative of a minimum power to be supplied to the motor in order for the motor to move the movable barrier;
an external power supply configured to connect to an electrical outlet, the external power supply including a plurality of outputs each having a power rating indicative of a maximum power the output supplies, the power rating for each output of the plurality being less than the motor power rating;
a combiner circuitry operatively connected to the plurality of outputs of the external power supply and the motor, the combiner circuitry configured to combine power received from the plurality of outputs of the external power supply and provide the motor with power that was combined from the plurality of outputs of the external power supply; and
a monitoring circuit operatively connected to the external power supply and configured to detect a fault condition of any of the plurality of outputs of the external power supply.
