Abstract
A load module determines that a load of an electronic device is operating at a power level below a predetermined power threshold. The electronic device is configured to receive power simultaneously from two or more redundant power supplies. Each redundant power supply configured to receive input power from one or more power sources and configured to provide regulated output power to the load of the electronic device. A disconnection module disconnects at least one of the two or more redundant power supplies from the one or more power sources in response to the load module determining that the load of the electronic device is operating at a power level below the predetermined power threshold.
