Abstract
Embodiments herein relate to a circuit which allows the re-use of an existing power supply units having main power rails and an auxiliary power rail, while supporting large memory configurations in a sleep state to avoid data loss. A processor determines whether a power requirement of memory modules in a computing device exceeds an available power of the auxiliary power rail. If this is the case, the processor asserts an override signal which is used by a logic circuit to force the power supply to remain on in the sleep state. A set of switches disconnect the main rails from other components which can be turned off in the sleep state. A select circuit selects one of the main rails to power the memory modules.
