3.3, 5, 12 as usual from the. Unfortunately, they’re really quite expensive, and a bit out of reach for most hobbyists. I'm going to use it for my car electronic projects that the reason i have to modify the psu circuit to have dc output of +13.8v.

Assuming the yellow 12 volt output of the first supply is connected to the black negative of the second supply, you can now get the following voltages. Please check on description, my comment on youtube and do step by step you will get good 220v to 24v 15a | power supply | switching power supply i try to make the pcb bysprintlayout and order pcb online on. When this “jump” is broken, the psu shuts off.

Another reason to get a proper lab power supply instead of. A lot of people started to ask me for a schematic, however i had to respond. In order to do so, you will have to short the green wire that goes inside the big connector to ground (ground can be any of the black wires).

The best source of power in the computer is the +12v rail. Atx power supply 18v and 30v modification. Ac power cord, most of atx power supply does not come with one, so you need to get it separately.

Encyclopedia of atx to bench power supply conversion : You cannot even try to use two separate but identical pc power supplies that output 12v because the negative terminal of the 12v is always connected to the common earth ground terminal at the input ac connection on the power. Support me for more videos:

Check the voltage for each wire. It should be interesting to both those who want to do a conversion, and to those intere… You need one to open the atx power supply casing if you want to mount the breakout board on it.

Because i am new here i will give a little background on me i have used the atx supply on many projects including a have made and using a 24v by combining 2 supplies. It offers up to 100 amps at a voltage of 12 volts. With the dc negative black wire floated (disconnected) from the metal case and mains power ground you can get a range of voltages from the two atx supplies.

Screw driver, i am using 4 in 1 screw driver set. Being a budding beginner hobbyist in electronics with about a year blindly stumbling about with arduino and esp8266, just completed my dyi third hand i figured i am committed enough to have a stab at the mandatory atx to bench power supply conversion so my plan is to use an old atx case from a pc and an old atx power supply both of i which i have plenty of. This power supply is rated at 350w and has two 12v rails unlike the mini power supply which had only one 12v rail.

For this project i am using an old atx power supply which has been salvaged from an dell optiplex desktop. The reason why i have chosen to make this article was the increasing number of popularity of my atx supply hack, which i posted on 4hv.org and simultaneously on youtube in august 2011. Power supplies are essential for at home tinkering and electronics hacking.

Schematic pcb gerber file, pdf file for make at home. Very useful if you intend to make and test circuits at home. The standard atx plug will also have seven.

The psu needs a connection to the motherboard to be told to turn on. The best source of power in the computer is the +12v rail. This guide has almost every atx computer power supply to bench power supply published to date on instructables ( as of dec 2014, about 70 unique instructables).

All atx power supply will have voltage and power ratings printed.power rating will be different for different. This is a real atx to regulated supply conversion, which might come in handy for you. I'm also in the process of building lab bench power supply from 300w atx psu.

Now, test your atx power supply first before you hack it.
