Intro: Bench power supply using PC power supplyThis comes in handy for testing most DC circuits that use 1.2 VDC up to 20 VDC. Total cost was less the $20. I know that this doesn't have the best looking wiring on theinside but I rushed placing components because I really needed it do for testing components at work.
Warning: In this project you wont be inside the PSU but if you do open it make sure to give a day or to unplugged for the capacitors to discharge. The wires coming out ofthe PSU only have 3 Amps so besides a quick shock there wont issues.

Step 4: CircuitI tested the circuit on a bread board first.
note: the voltage regulator can have different pins from what is shown. make sure to look up the stats sheet.
Step 5: Future improvements.Add a USB port to it by connecting it to the 5 DCV.
Add a cigarette lighter to the 12 DCV if I can get it to fit inside case.
a built in voltage meter.

lhj734017 says: Jul 1, 2014. 2:59 PM REPLYwhere in the schematic is the diode supposed to go? I only see the location of the LEDs. I see the diode attached to one of the legs of the regulator chip in thepicture but im having trouble following your wiring
klilly1 says: Jul 1, 2014. 5:27 PM REPLYThanks for noticing that it goes in between the output leg and + 12 VDC I'll edit that when I get a chance.
jedii72 says: May 31, 2014. 7:48 AM REPLYCool project. Question: I was told that when you combine the + and - 12V, yes you get a loss, but you should not sure any of the Outs (+5 or +3) at the sametime because the phase difference the 12Vs are using simultaneously will mess up the Vout. Have you experienced any such problem? Note: it was an electricalengineer trying to explain that to me, but since I'm not an engineer I may have lost something in the translation so my understanding my be wrong.

klilly1 says: May 31, 2014. 11:14 AM REPLYthanks this is all DC voltage so the phase will be constant also you do get voltage loss because the regulator needs to use some of it to work. I hope thathelps. I could also explain why I use a negative and a positive voltage to get double the voltage.
mstone25 says: May 14, 2014. 11:55 PM REPLYAh sorry ignore my comment, I see you are using + and - 12V. :)
klilly1 says: May 15, 2014. 5:13 PM REPLYyeah I'm using +12 and -12 the and the most voltage I get out of it is about 20.1 VDC because of the loss.
mstone25 says: May 14, 2014. 11:52 PM REPLYYou do know that you can't get higher Vout than Vin don't you? In fact you'll lose about 1.6V across the regulator so best you'll get is around 10.5V with a Vin of12V
