Just because it has the ports doesn't mean it has the internals to support them. I would check that before doing anything not to spec... it's a power supply.
Does it though? Is that connector actually functional? And if it is, does the PSU inside have the required wattage or will it trip when you plug something into it?
Unlike the hidden USB sticker, this is a power supply that is sending high current through its wires/connectors... please be careful for your own sake<p>Edit: fixed a technical issue about current & voltage
