Okay, I have 2 different power supplies in 2 different cases. Not really planning on using these power supplies. I was just thinking that if the computer runs on 12v and there are ground connectors, is it possible to run a set of car lights or a car radio or something along that line off of one of these power supplies? I am not really planning on doing this but when working with different car electronics that need 12v to run off of just for testing just figured it would be easier to run it off one of these instead of going out to hook it up to the battery just to test it. This is just a thought and want to get others opinions on this idea.
