Power supply communications via a shared channel for performance management

A power supply comprising a hardware interface having conductive contacts and conforming to a power supply design standard comprising a pin-out definition specifying that a first conductive contact is to be dedicated to communicating first information of a first type. The power supply comprises first, second, and third circuitry. The first circuitry is to determine the first information. The second circuitry is to determine second information of a second type, wherein the second type of information is other than the first type. The third circuitry is to send, via the first conductive contact, a communication comprising the first information and the second information. In embodiments, a PCB comprises a connector to couple the PCB to the power supply via an interconnect to be coupled to the hardware interface, and an IC to receive the communication, and identify the first and second information.
