A power connector (100) has a mating plug (10) having a number of contacts (110), an internal printed circuit board (30) mounted to the mating plug and located in one transverse direction perpendicular to the pluggable direction, a cable (20) connected to the internal circuit board, and outer barrel (50) enclosing the mating plug and the cable. The internal printed circuit board defines a conductive area (31). The cable provides a connecting section (24) connecting with the conductive area of the internal printed circuit board and extending through the internal printed circuit board to connect with the contact of the mating plug.
