1. An information handling system comprising:
a power supply unit to provide power to components of the information handling system, the power supply unit including:
power monitoring circuitry to:
monitor the provided power;
determine whether the provided power exceeds one of a plurality of threshold voltages during a respective one of a plurality of time periods, wherein the threshold voltages increase as an amount of time in the time periods decreases; and
provide a digital value on one of a plurality of pins based on one of the threshold voltages being exceeded during the respective one of the plurality of time periods; and
digital-to-analog circuitry to communicate with the power monitoring circuitry, the digital-to-analog circuitry to:
detect the digital value on one of the pins; and
provide one of a plurality of quantized voltages, wherein each of the quantized voltages corresponds to a different one of the pins; and
a motherboard to communicate with the power supply unit, the motherboard to:
receive the one of the quantized voltages; and
activate a throttling operation based on the received one of quantized voltages.
