1. An information handling system, comprising:
a power supply unit comprising a mechanical relay and a first programmable integrated circuit, the first programmable integrated circuit being programmed to control operation of the mechanical relay to selectively provide electrical power to one or more power-consuming components of the information handling system;
a host programmable integrated circuit programmed to control power state transitions for the information handling system, the host programmable integrated circuit being programmed to transition the information handling system from a higher power state to a lower power state; and
a second programmable integrated circuit coupled to the host programmable integrated circuit and the power supply unit;
where the second programmable integrated circuit is programmed to respond to the transition of the information handling system from the higher power state to the lower power state by providing at least one first command signal to the first programmable integrated circuit to cause the first programmable integrated circuit to control the mechanical relay to turn off and remain turned off while the information handling system operates in the lower power state.
