There are lots of ATX Power Supplies out there in old computers. So i took one and made a Lab Bench Power Supply. It's a great project to start and to learn basic stuff about electricity and soldering.

I compared different projects here at hackaday and at instructables.
I decided to use 3.3V, 5V and 12V for my lab bench power supply.

    Step 2

    Organize the wires by colour to keep a good overview about all the different wires they are in such a device

    Here you can see the colour codes and the purpose of the differnt wires.

    Add the brown wire to the orange wires and the pink wire to the red wires as explained in the picture.

    We don't need the blue wire so we cut that off and isolate it.

    For the switch and the LEDs we need the green, grey and purple wires and 3 black wires.

    For the additional fan and the minimum load we need 2 red wires and 2 black wires.

    If you want to add a USB Port. Put another red and black wire aside.
