I Built my own Power Supply (don't do it)

I hate to say it but Seasonic isn't wrong.

Therapist:how would you like to die? me:building my own psu carelessly

i love these electroboom guest episodes where he isnt even there

This video has a lot of warnings for a good reason. For the love of god people don’t mess around with power supplies if you don’t know what you’re doing. Be safe.

recently built a small home server with an itx motherboard featuring an embedded intel n100 cpu, and hooked it to a pico power module from Rgeek (aliexpress), I hooked it to a switching psu made for running LEDs; the whole thing uses under 65w with 2 hard drives on it. worked like magic, 3d printed a case for it, painted it black, put it in the same corner I have my router. It was really cheap and its pretty small. Do not use these things for a gaming pc dear god.

The title of this video made the video before I even opened it.

Seasonic actually lowering a price of a component because the manufacturing got cheaper is a wild change of pace

I mean, some build bombs, right?

Now this is the unhinged content I look forward too

ElectroBOOM is gonna have an aneurysm watching this video

Bomb has been planted

Should have been another ElectroBOOM crossover 😂 😊

I feel like handling a deenergized power supply someone else said they totally did right is like pointing a gun at yourself someone told you they definitely unloaded, and you weren't able to check.

As someone that's fully capable of building a proper PC PSU. I would never build one myself, to actually do it right'd be an absolute nightmare and buying all the bit components in the numbers used for one you'd be paying far more. Now if I use the parts I, an electronics repair man and terminal tinkerer, have on hand then I could do it cheaper. For a few dozen hours in labor that I obviously wouldn't charge myself for. Your significantly smarter than average user would more likely take 10x the price and around a year of learning and building up to it to make a DIY PSU work proper (To my admittedly strict safety and performance standards anyway). And that's probably me being generous as my time to go from no knowledge on electronics to being able to do that was around 5-7 ish years. But that's learning on an adjacent job where I sort of slowly picked things up over time and then a while of repairing PSUs and not directly trying to build them. Edit: Oh this is off the shelf modules, not components. There's a follow-up video idea ;) Components a lot of people could do but getting them from a reputable enough place presents issues. What consumers can buy there is quite random and the people selling actually decent modules don't tend to sell to consumers. Making most module purchases quite the gamble.

Searching for ElectroBOOM's comment...

I wanna see Medhi (elctroboom) create a power supply from scratch now LOL

People who build PCs in the sff (small form factor) world go down this route very often and luckily there's some more intuitive routes. The company HDplex makes a DC-ATX converter that can support those 19-20v laptop psu's (from Dell, etc.) which makes it very streamlined. It becomes as simple as plopping in the DC-ATX converter on the MB and plugging in the laptop barrel connector externally. There's nothing exposed and it turns out extremely clean-looking.

Great tutorial video thanks. My son is in his bedroom following this as we speak (He doesn't have any electrical training but he's really clever and picks things up very quickly). Thanks again.

Fall 2022 I built a simple lab power supply 16v max and probably 1 or 2 Amps. It was extra credit for one of my college classes, it worked fine and I had a schematic for soldering it together. The next semester I had to design one that would take an alternating signal and produce a dc signal. Even had to build the bridge rectifier to get measurements even though we had a chip. It was low power and not reliable, my first one I still use today. I do not however want to build a pc power supply, but I could work on one after I discharged it and feel confident it wouldn’t explode,but don’t worry I won’t ever do it.

linus took the seasonic sponsor personally
