Turn a Computer Power Supply into a Desktop Power Supply
If you’re looking for a desktop power supply for your electronics workbench, this tutorial video shows you how to turn a computer PSU into a desktop power supply.
In the above video the guys at JumperOneTV show us how to make a desktop power supply. As an addendum to the video; they note in the comments section on the YouTube video that they were wearing gloves for the drilling and that they did a very thorough job cleaning out any loose metal shavings with an air compressor. If you wanted to play it even safer (and you should!) you would remove the circuit board from the enclosure before doing any drilling.

am i listening to microsoft sam?
It would be cool to have a power supply with a dimmer switch so that you can regulate the voltage for PC muffin Fans and make a geek desk fan for work
Also can be used virtually as is, to power all those external hard drives, and devices you may have.
Just connect the green wire to a black one.
More electrical work?
Howly,
This video was SuperDoopa! Loved it!
When I was watching the vid I realised, I get myself some new tools… :O
Video = Approved!
Why use two resistors? By my calculations and as you wired them in parallel you are only getting 5.499999995 ohms. Is the other half an ohm worth while or is there some other reason you would use two resistors in parallel ? Did I miss something?
lol, I managed to fall asleep! This guy has a really boooooooooooooooooring voice.
@fredneedle – using two in parallel produces a larger dummy load.
