Lietu : Two additional factors to look into when choosing a power supply: Warranty length, and MTBF - Mean Time Between Failures.

A Seasonic PRIME ULTRA TITANIUM is going to have a 12 year warranty - it means the manufacturer REALLY believes in their product being high quality and lasting you a long time. It also has a MTBF of 150,000 hours - which is a lot.

Be Quiet gives some of their power supplies 2 years warranty, some 10 years, some 5 years. Anything 5 years and above is probably worth buying, 8 years and above is probably pretty high quality, less than 5 is probably trash.

MTBF of 100,000 hours is good - but if they show numbers far below that, you should probably be worried.

If they don't list MTBF or advertise their warranty - it's probably shit, and you should stay away from it.

Carlos Fernandez : I'm a 38 y.o. PC newbie. Thanks to channels like yours, I'm even surprised I owned only Apple computers.

Thank you for all the info all the time, you do an excellent job.
Phil harmonic : Beginners guide to power supplies: You'll need one in a couple of years when you can actually buy the other parts that go in a PC.
Jhon Jhonson : I always thought power supplies were pretty awesome. They're probably the hardest working component in your system with the highest build quality compared to any other part.

ATX Bench Power Supply - Convert a Computer Power Supply

A computer ATX power supply can be easily converted into a versatile and powerful power supply for your workbench. In this video, I’ll show you how easy it is to make that conversion.

A power supply is an essential piece of equipment for any electronics experimenter. While you can get by with USB adapters and “wall warts” having a capable high-current source of 3.3, 5, and 12 volt DC power will take your experimenting to another level.

Commercial power supplies with these sorts of current capabilities can be very expensive, however, there is a much cheaper alternative. With some simple wiring, you can convert an ATX power supply from a desktop computer into a reliable and capable workbench power supply.

Even if you need to purchase a new ATX power supply this method is still a lot cheaper than buying a commercial workbench power supply. And chances are that you won't need to spend any money at all on the ATX power supply, I salvaged mine from an old Windows XP computer and it works just great.

There are two types of ATX power supplies commonly in use, I will show you the differences between them. Either model can be used in this project.

Here is the Table of Contents for the video:

00:00 - Introduction
04:36 - Parts used in Project
10:06 - ATX Supply pinouts
13:46 - ATX Supply Inside
16:17 - Testing ATX Supply
19:14 - Hookup Diagram
22:48 - Building the Power Supply
30:17 - Testing the Power Supply
31:59 - Adding a Power Meter

One note - there are many ways to do this and I outline a few of them in the video. Several methods (including the one I used) involve opening up the ATX power supply. If you do that BE VERY CAREFUL as some of the components in the supply can retain a high-voltage charge for hours or even days after the supply has been unplugged.

If you are unsure about opening up a power supply (or if you have a new one still under warranty) don’t do it, you can still build this project another way. I go over that at the conclusion of the video.

As always there is an article on the DroneBot Workshop website that accompanies this video, you can read it at https://dbot.ws/atxpwr.

David Cole : I am 72 years of age, and I so wish you had been a teacher at my school way back in the 1960's. Every aspect of your youtube vid is 100% perfect, no music, clarity of annunciation is great, presentation cannot be faulted, even at my age I am still learning thanks to you.
Please dont' stop.
Thank you.
Al S : In the midst of building this with a 3D printed case, thank you very much for a comprehensive and detailed overview, so helpful and useful in planning our project !!
Chuck Kirchner : Hi Bill. I have been a subscriber for about a week, now, and have seen a few of your videos. I'm a retired Broadcast Engineer, and have spent most of my adult life in electronic repair. I think I can honestly say that even though most of what you cover is old hat for me, I still manage to learn something from every video. Usually it involves something "taken for granted but never fully understood". I will be recommending your videos to a few of my friends still actively involved in Electronics Engineering, and a few "young folks" just starting out. I built my ATX PSU several years ago, and I admit it's more complicated than it needs to be, at least compared to yours. I found that an LED on the 5-volt line is enough load to keep mine running properly. Thanks for the effort you put in to each of your videos, and I encourage you to continue. My favorites are Arduino and Raspberry Pi related videos, as I've got a few Arduinos, and I just bought a Pi to tinker with. Thanks again.
chemicalcorrosion : Amazing. I was literally taking a break from building the same style PS. I was researching the different 5V lines. Thank you so much for your informative videos. Now I will add the volt/amp meter. I enjoy your videos so much.
Ian Pearson : Fantastic presentation.....this is so user friendly especially for those that are relatively new to anything electronics.
I like the coloured voltage levels etc and the wire paths with the visual presentation of the inputs and where they go to......even my long deceased granny could follow this plan and she was into crystal sets in the 20's.

El Cana918 : Great vídeo keep up the good work thank you for all this amazing videos that help all of us to repair our devices !!


Marcos A. : My PS5 PSU failed after a lightning strike. Managed to get a psu from Ebay and the other accessories from amazon, including the magnetic screw mat.
This tutorial was a life saver, i’ve never done anything similar to this fix and following carefully the video i was able to change the PSU and now my PS5 is working fine again. Thanks!
Jason Dumas : Seems a lot more simpler to disassemble than a PS4 specially the disc drive
Mary serna : hello thank you very much for your video .. where do i buy the power supply to replace
G Val : Where did you order the piece from ?
