with this quick design and print ( you can see on the photos the 0.25 layer was not a good choice to make) I was able to reuse a old ATX Power unit as a Desktop power supply.
There is no big trick about it.
I just cut off the connectors and soldered the wires to 4mm single connectors.
Color code
Green >> connected to Black with a switch and the Power supply starts up.
Black >> Ground
Orange >> 3.3V to connect the LED i used a 220Ohm resistor
Red >> 5V to connect the LED i used a 270Ohm resistor
Yellow >> 12V to connect the LED i used a 680Ohm resistor
Blue >> -12V to connect the LED i used a 680Ohm resistor ( since it is -12V you need o connect the LED the "wrong way around". The Katode goes to the Blue and Anode to black).
Thats it quick and easy power for many projects to come.
