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

Ever thought about trying to assemble your own power supply out of a few separate parts? You probably shouldn’t, but we definitely did. Is it a competent power supply? How does it compare to higher end power supplies like those you might find from Seasonic?

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

[Ekyllier]

7:30 I am always blown away at how incredibly amazing Wiki is and just the sheer amount the time and effort people put into maintaining these sites/databases. What is just a quick and easy to read table to find what information you need in 30 seconds could have been an all day research task if this didn't exist.

i love these electroboom guest episodes where he isnt even there

Tanner: So it died?
Lucas: "Yeah"

Segue to Linus: "In conclusion, does it work? YES!"

You can't fool me movie magic

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

[djdman]

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.

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.

[robertlinke]

this is a good time to bring out the old LTT Addage: Do as we say, not as we do
DO NOT TRY THIS, YOU GENUINLY MIGHT DIE

[therealhatchet]

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

[TechnologyAll]

Honestly, with how much Seasonic has been on board with your guys' ideas, as well as being an amazing company in general, I don't even mind ads for them anymore, lol.
It just makes me happy my system has one, and that if something were to happen to my PSU, they'd most likely take care of me.

Would love some sort of factory tour of theirs btw! Dunno if that's possible.

[iDeadxInfected]

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.

HP server PSUS can be found for less than 10$ and not only use titanium 80+, but are also easily modified to output something like 12V 70A by bridging two pins with a resistor.

ElectroBOOM is gonna have an aneurysm watching this video

"Be careful when it's turned on"
*touches it with bare hand*

[ezforsaken]

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.

I liked that the sponsor read at the end of this one was actually a mini technical explanation rather than a sales pitch. Cool technical stuff is more interesting to me than "generic sales pitch" 😊

5:22 Missed opportunity for "FUUUULLL BRIDGE RECTIFIER"

[carpdog]

The one advantage that I can think of is that if you have the voltage regulators separate from the 12V supply, then you could run the PC directly off its battery backup; skipping the whole step of bumping it up to mains voltage in order to run a power supply. I actually considered having 12V power in the house and running PCs off it with a central power supply. Then I realized how much amperage that would need to carry and how thick the copper needed to be, and discrete supplies started to look a lot smarter.

Fun fact: I work at one of, if not the only tech shop in North America, that does the Frankenstein mod to the backward compatible PS3 to keep em alive! We even got a dev PS3 shipped to us from Germany once!

[jayzo]

You could've got a high-power refurbished server power supply, one of the redundant ones with the edge connector, hacked it to turn on without the PSU backplane (or bought a module that emulates a backplane to enable the power out, and plugged this into the power modules. I bought a 750W server PSU refurbished with a warranty for about 29 CAD. They're dirt cheap refurbished, are high quality given they served time as a server PSU, and they're very powerful for their compact size.
