A computer system that includes supply programming circuits for remotely programming a power supply such that minimum operating voltages are maintained. The computer system includes a power supply having a supply output line and a supply sense line. The power supply provides a supply voltage via the supply output line in response to a sense voltage received via the sense line. A first circuit that operates at the supply voltage is coupled to the supply output line. A first supply programming circuit is coupled to the first circuit, the supply output line and the sense line. The first supply programming circuit senses the supply voltage at the first circuit and adjusts the sense voltage in response to the sensed supply voltage at the first circuit. A second circuit is also coupled to the supply output line. A second supply programming circuit senses the supply voltage at the second circuit and adjusts the sense voltage in response to the sensed supply voltage at the second circuit. Only the supply programming circuit that senses the lowest supply voltage adjusts the sense voltage.
