Super Cool Bench Power Supply

Introduction: Super Cool Bench Power Supply

About: Just two guys a Geek and a Sparky here to change the world. We just believe Art without Technology and Technology without Art is nothing. We just wanna make things, things that don't affect the environment,bu…

Every hobbyist wants to have a Bench Power Supply, either for testing or powering.So We gonna make one using a PSU from a old PC

Step 1: Gathering the Parts

We gonna turn some old PSU from a PC to a Bench Power supply with a Voltmeter and Continuity tester.

Part list:


Buck boost converter


Banana Sockets

Push to ON switch

USB Female

Continuity Tester

Acrylic Sheets

Step 2: Understanding, Planning and Tinkering

The next important step is planning out, how your power supply is going to look and mainly the dimensions of the parts top be fitted, this is gonna take some time but its worth the time.

I wanted something different, sleek and make people think what this would be.

Understand how the computer PSU works also matters, you can find out a lot of details on ATX power in the net.

Open the PSU and learn the wiring, most of them have the details marked on the PCB itself

I'm using Autodesk Fusion 360 for designing. Export the sketches to .DXF diagrams

and Laser Cut the sheets

Do not remove the protective cover on the outside of the Acrylic Sheets, they protect from scratched till things are done.

Check if all the components fits into the holes.

Solder, Sleeve the wiring and Add crimp terminals.

Start gluing from the base,

Before closing the chassis, Test!

On Success full test close the box.

Step 3: Finishing

Once finished with gluing start removing the Protective film from the below, I used some Aquarium suction cups for the base to make it anti skid.

Follow and remove all the covering.

Power On and enjoy your new bench power supply.

Cheers :)

    you did a great job on this project and I LOVE the way it looks. Thanks so much for posting... honestly exactly what I'm looking to do at the moment. looking for what I need to pick up offline- that I haven't already savaged from "obsolete" or "broken" equipment (it amazes me constantly how people will replace $100s pieces of equipment without even a simple look 'under the hood'. however, that's how I've acquired almost all of my expensive equipment (industrial compressors, generators, lawn mowers (riding & push), even replaced my welding rigs- stolen years back along with $1000's in tools by riding off with my trailer- with better set ups than before and COUNTLESS engines: so no complaints from this side!

    Anyways, far off topic- thanks so much for the post! Now Ive just gotta figure out how so many people have access to CNC's, laser cutters, etc. haha. any ideas would be crazy helpful!

    As for the leaf and "kid friendly" remarks- if kids are working on their own DIY bench power supply units or anything with current so high (pun absolutely intended)- you can bet that they're not so niave to life, in general. wouldn't they need to know what the leaf represented to begin with? have your own opinions as to 'reefer madness' but don't impose them on others and use the "what about the children?!" trope to justify it. it's absurd and no reason to 'critique' someone's work that's truly got nothing to do with project at hand. offended, move on- negative posts and judgement unnecessary. While I don't understand any correlation between being 'kid appropriate' and having a picture of a leaf (unless said leaf represented violence, hatred, or discrimination of any sort)- it's a site for anyone of any age (not to mention the exposure kids get to violence/death on any/all platforms) and is not any makers responsibility to curtail to any slight offense that might bother you... grow up.

    Now, off my soap box, and apologize about diatribe- just sick of the negativity, especially without any constructive criticism other than 'you offend my morals'... I love the individuality of your make and, if you wouldn't mind, may I hit ya up with a question or two, should they arise? Thanks Again!

    I agree with tankapotamus. I feel the use of the pot leaf is inappropriate. Keep in mind you have children that use this site as well. As a mater of fact I use this site for my 550+ students to motivate them to explore making. Let's keep this site positive.

    You should have add more detail; wiring diagrams, pictures of the pre and post wired components, pictures of how the case was assembled, and pictures of how the pcb fits and is held into the new case.

    P.S. Don't use pot leaves for things you enter into a contest, you never know if a judge will have a negative view of it.
