Abstract: A disclosed apparatus may extend hold-up times for computing devices with redundant power supply units (PSUs). For example, an apparatus may include a plurality of PSUs and a controller. In one example, the PSUs may be configured to convert power from at least one AC input into a direct current (DC) output and to provide the DC output to a computing device. In this example, the controller may be configured to detect a loss of the AC input and a failure of a first PSU included in the plurality of PSUs. The controller may also be configured to extend a hold-up time of a second PSU included in the plurality of PSUs by boosting an undervoltage lockout signal monitored by the computing device in response to detecting the loss of the AC input and the failure of the first PSU. Various other apparatuses, systems, and methods are also disclosed.
