Abstract: Disclosed are various embodiments of power source redundancy in a power supply for a rack mounted computing device. The power supply includes a plurality of AC power converters configured to receive power from corresponding power sources. A first AC power converter provides DC power to a common DC bus of the power supply. A second AC power converter provides DC power to the common DC bus in response to a change in the voltage level provided by the first AC power converter.
