Abstract

See full text

An information handling system includes a power supply unit (PSU) and a motherboard. The PSU provides power to components of the information handling system, and includes power monitoring circuitry and digital-to-analog (D/A) circuitry. The power monitoring circuitry of the PSU determines whether the provided power exceeds one of a plurality of thresholds during a respective one of a plurality of time periods, and provides a digital value on one of a plurality of pins based on one of the threshold voltages being exceeded during the corresponding time period. The D/A circuitry of the PSU detects the digital value on one of the pins, and provides one of a plurality of quantized voltages. Each of quantized voltages corresponds to a different one of the pins. The motherboard receives the one of quantized voltages, and activates a throttling operation based on the received one of quantized voltages.
