When I got the Gateway Profile 4, it didn't come with a power supply so I had to fashion one myself. I didn't realize that it was a funny connector and 13.3 amp 12 volt supply. Fortunatly enough the connector is like the extra connector on computer power supplies. Also fortunately I had some extra power supplies. My first try didn't go so well. I didn't realize to run the 12 volt rail you need a load on the 5 volt rail or else you can burn out the power supply. So some internet searching later and I came up with what you see above. I didn't realize people modify these PSUs for battery chargers. I used a 10W 10Ohm resistor across the 5 volt leads and I zip tied it to the back of the case so the case can act as a heat sink. It doesn't seem to get hot at all. Also to fit the power plug I just cut off the retention clip off the extra 12 volt line and viola.
