Tutorial to transform an ATX PC power supply into a laboratory power supply. This power supply gives you 3.3, 5 and 12 volts. For the amperes, I don't know how to tell you, since I don't have a sufficiently precise multimeter.
I present to you my adjustable power supply that I made. The power supply is variable from 11V to 35V and there are also fixed voltages of 3.3V, 5V, 12V, -5V and -12V. All the assembly is based on a computer power supply (PC) since this kind of power supply is very powerful and very compact. The variable section of the power supply is based on a small 150W DC-DC converter module. I also decided to add an integrated voltmeter to have a real-time reading of the output voltage of my adjustable power supply.
