Abstract: A power supply may include a power input to connect to a power source to receive an input power for the power supply, a bulk capacitor operatively connected to the power input, and a threshold manager having a processor operatively connected to the power input and the bulk capacitor. The threshold manager to monitor the input power, calculate a threshold to perform a shutdown operation based on a shutdown requirement provided by a computing device, and in response to a power loss of the input power, monitor a bulk voltage of the bulk capacitor and send an alert to the computing device to perform the shutdown operation when the bulk voltage meets the threshold.
