A printed circuit board assembly (120) for a peripheral is disclosed. Components of the printed circuit board assembly (120) include a printed circuit board (122), a power connector plug (124) having a first cavity (158) with a plurality of power pins (162), and a cover (174) that is disposed within the first cavity (158). There is an interference fit or the like between an the outer perimeter of the cover (174) and a connector housing (128) of the power connector plug (124). Each of the power pins (162) is disposed within a corresponding hole (206) on a first end (182) of the cover (174) that is preferably sized so that the pins (162) do not contact the cover (174). Each such hole (206) has a closed end such that the cover (174) individually encloses at least an end portion of each power pin (162).
