An advanced connector assembly enabled to receive and distribute power signals. In one embodiment, the connector comprises a multi-port modular jack, and incorporates a PSE controller board disposed in the rear portion of the connector assembly, e.g., outside the connector housing. The PSE controller board controls the power to a powered device and may be adapted to, for example, distinguish whether the device is a short circuit or a network interface card, guarantee the supply of power to selected ports, and prevent cables from transmitting abnormal power. Heat removal features are also optionally utilized to effectively dissipate heat produced by the electronic or signal conditioning components utilized on said multi-port modular jack. In some embodiments, the PSE controller board is also optionally made removable from the jack housing.
