Hi, all this is my first post. I searched and could not find the answer to my question. So, here goes.
I have made a my own powersupply from an ATX computer supply. It is a 600W Coolmax, now it has 3 12V power outputs two that are rated at 18amps and one rated at 15amps. So, I have 3 12V outputs that I can connect to. Now when I apply a load to any one of the three the voltage on the other 2 drop to the same level.
And with a 5amp load the voltage drops to 11.5v with a 15amp load (spread across to outputs) it drops to 10.6v. I would like to know how one would be able to stablize the voltage to stay around 12.5v or higher under a 15 to 20amp load.
