Thread: Power supply for a msi wind desktop car puter?

I want to use my MSI wind desktop PC as a carputer, but it uses its own special ac adapter. So im guessing i have 2 options to power it, but im not sure which is the best solution.

The ac adapter that comes with it, plugs into a regular wall socket, and outputs 9v (3.25 amps) to the back of the pc with its own little connector (similar to notebook ac adapters).

Would it be better to purchase a shutdown controller that outputs 9v (like one of the ones on mp3car.com) and attach the output to the special end of the wire from the ac adapter so that i can power on and off the pc?

Or would it be better to purchase some type of shutdown controller that the ac adapter can plug into (wall socket 2 prong) style. (if such a thing exists)?

any other ideas?
