Systems and methods of interconnecting devices may include an input/output (IO) connector having a buffer with an integrated voltage regulator. The integrated voltage regulator may include a first supply output and a second supply output, wherein the IO connector includes an IO power contact coupled to the first supply output. The IO connector may also include a logic power contact coupled to the second supply output. In one example, a host device may issue power management commands to the buffer in order to scale the second supply output independently of the first supply output.
