Examples are disclosed that relate to power supply devices and methods for managing DC power. In one example, a method comprises: providing DC power at a first voltage until determining that a standby time period has elapsed; determining that a load is connected to the power supply device; and based on determining that the standby time period has elapsed, entering a restricted power mode, wherein the restricted power mode comprises either: deactivating the DC power, or (1) providing the DC power at a second voltage until determining that a load detection time period has elapsed, (2) deactivating the DC power after determining that the load detection time period has elapsed, and (3) repeating (1) and (2) until determining that the load is no longer connected to the power supply device.
