HOW TO Start & Reuse A Computer Power Supply WITHOUT A Computer | PC ATX PSU Upcycling

- Today, we show you how to kickstart and reuse a ATX PC computer Power Supply Unit (PSU) WITHOUT a computer. Old PC computer power supplies make great power supplies for projects! They come with good overload and overheat protection built-in, and commonly offer out of the box 3 output voltages: 3.3 volts, 5 volts and 12 volts. But, getting them to work outside of a computer can be however a little tricky since when taken out of a PC, they may not even start at all! So, if you have never seen it, let me show you why and how to fix it / make it work.
► NOTES
► Several IDE and floppy drives connectors, a 20-pin P1 molex, a 4-pin P4 molex to support Pentium 4 power and a 6-Pin P2 connector, no doubt we are dealing here with an ATX power supply version ATX12V1.0.
► I'm using three 12-volts halogen light bulbs to test if we get power on the 3.3 volts, 5 volts and 12 volts rails.
► Different power supplies may have other requirements for a stable voltage supply: minimal load required on 3.3V, 5v or 12V rail, ""voltage sense function, ... so, check out the documentation of your ATX power supply.
► DISCLAIMER
Always make sure you operate in a safe and secure manner.
Playing eletricity can kill real bad.

Thanks sharing this information and video. I am planning to create a DC Variable voltage and current Power Supply from an old ATX power supply.
Nice!
Great little trick! Puppetry of the Power Supply, HILARIOUS!
Happy you liked it!
Thank you very much !!!!
Please, is there any way to get around 1.5v from a power supply unit ?
Thank you for this, I am going to be using a laser project for this one, using the 3.3V rail.
Good to hear, good luck with your project
Solid jam.
🤘
Thank you for that. You have a new subscriber.
Welcome
thanks, just what i searched for!
Nice, good luck!
@@TheLabOtomy that it doesn't blow up, or why? XD
@@JohnL_S17No, just a friendly go for it and have a nice day kinda thing... yes I know this can be overwhelming when somebody does not insult you on the internet 😊
Thanks I needed this
Welcome
Hi and thank you for the Tutorial, the formula does not apply with my power supply box, this means that it is crashed, what else can I do to repair it?
Start with visual inspection, check for anything that looks burnt or busted
You need to do a longer video just for the music.
Will do
can I combine two power supply and tie the wiring together? what will this give me as far as volts and amps? ty for your assistance. 🙂
Not recommended I believe since a delta in specs / outputs between PSU can lead to serious issues.
@@TheLabOtomy okay and ty for the reply
And what about the pg wire where I to have connected it and will it run without pc wire connected to motherboard ????
The Power Good (PG) signal is sent from the PSU to the motherboard. It is important for the MoBo to start, not for the PSU to start.
Does COM stand for common ground?
Correct
Sounds like the MCP is relegated to narrating yet vids
Yes
i try all day long to power my monitor. Of course, i dont join the green and black wire.
GG!
What about a proprietary PSU, like Dell/Alienware and such that have a "Power OK" pin in the mobo connector?
They may use different wire colors than and may have own requirements for power sensing (brown cable could be a grey or pink one for instance), but the principles to get the PSU started are the same: connect Power _on to ground, connect a dummy load if needed, connect power sensing if needed
@@TheLabOtomy okay, I will try just the 1 jumper 1st. Then power ok if needed. Thank you!
Today we play with Messi xdxdxdxdxdxd hahahaha
And we have too... see: ua-cam.com/video/qTHukKkBKe0/v-deo.html&pp=gAQBiAQB
This could be a really great video but please do it WITHOUT the hillbilly music, your voice is fine.
Me like banjo, yihah!
@@TheLabOtomybased
Ups
Thank you thats GND line
Yep
Logic
Agree
