I had an old 300W 19A computer power supply laying around so I decided today to convert it to a DC power supply for my RC stuff. I got everything done and when I'm using my Volt-Ohm Meter I have 12.8V coming out, but when I try to read Amps I'm only showing 2 Amps.

I'm trying to remember from my high school days in electronics if this is normal because there's no draw on it...For some reason I remember it not pushing max amps unless something is drawing from it to save power. Anyways if anyone is an electronic guru and could help me out I'd appreciate it!

Also, what size female banana connectors do I need so a DC charger will plug in?
