Introduction: Desktop Power Supply From Recycled Computer Power Supply
In this inscrutable I will walk you through building a desktop power supply from a recycled computer power supply. First off if you are wondering what a desktop power supply is and what it is used for , well it is a electronic device that takes the 120v or 220v from your wall outlet and reduces the voltage so that it can be used to power electronic inventions and things like electric motors and leds. For this inscrutable you will need only two components
* Computer power supply
* electrical tape
*******warning I am not responsible for any harm brought on by improperly handling high voltage or voiding of warranty on your computer or power supply*******
Step 1: Build It
The building process for the power supply is simple. First cut all of the connectors free of the wires coming out of the unit. Second find the light blue and green wires then cross them and cover the end of the wire with electrical tape. Then strip the ends of the other wires and plug the unit in. When you plug it in if the fan turns on it is working and is now a power supply for any of your electronic inventions. For the color coding
*yellow = 12v
* black= ground
* purple= -12v
*Gray = -5v
with all of these voltages you can combine them to form many different voltages.
Other uses: power supply for 3dprinter, power your maker projects, and power anything that needs power
