I was considering rebuilding my Defender power supply instead of using a switcher but I've heard that the Defender version does not have overload protection. Is there a way to make it bullet proof and not possibly fry my boards? Also, I recently picked up a Stargate that had the Defender type power supply which I heard came in the early production Stagates. On the main connection for the harness was a card installed between the power supply and the harness and I'm not sure what it is. Can somebody tell me what the heck this is for??
