- In this episode, Chris turns a salvaged ATX power supply into a useful benchtop power supply.
The wire color codes for most ATX supplies are as follows:
Yellow = +12VDC
Red = +5VDC
Orange = +3.3VDC
Black = Negative / Ground
Blue = -12VDC
Green = Power Supply On (connect to switch)
Brown = +3.3VDC Sense (connect to +3.3VDC suppy)
Grey = Power Supply Good (connect to + of LED, use resistor)
Purple = +5VDC Standby Power (connect to + of LED, use resistor and + of USB)
Your mileage may vary, please review the tech sheet for your individual PSU if in doubt.

Thanks from England for a good video because it's a bit hard to watch all these videos where everyone thinks they're a TV personality. So cheers mate.
Finally found a video explaining an ATX PSU perfectly! Thank you !Thank you!
You did a thorough, easy to understand presentation.
Donald Nakonechny could you help me bit ? Because my device is but different, there are different 12/1 and 12/2 and many others
Sounds like you have two 12V power rails. They're most likely from the same source but were split into two with individual power limiting.
You showed that car stereo Jammer saying you are gonna do a DIY vid on it and and I'm subbed!
I gave up on CATV in 2007 coz there were 300 channels but NO entertainment or engaging shows.
THIS is MY idea of video time well spent : ) even if I never pursue that particular project at all.
*Mind Expansion*
Thank you for the kind words! I unfortunately took a break from CZcams a few years ago now but am looking forward to returning soon. There will be MANY interesting videos in the somewhat near future.
very good video, great explanation of the power supply.
you are the only truthful one that has ever explained fully about this. thanks
Thank you for your comment!
That was actually a really useful explanation. I am so happy I came across your video. Thank you dude. I am learning so much from ya. Keep producing content like this, it helps the world.
Thank you for your comment! Sadly, I stopped producing content on a full time basis a few years ago after feeling "burned out". I have been contemplating a return though and your positive vibes help with that endeavor.
Published this video last year today and it is still one of my most popular videos.

Thanks man for all the explanation...❤
Great Video,
"so far the best on CZcams"
on this project,.
Thanks for the comment. Hard to believe this video was published a year ago today...
a few suggestions come to mind: 5v is too much for LEDs without a current-limiting resistor. The LEDs will overheat, draw more than needed power, and not last as long. If you don't have a resistor handy, use the 3.3v instead for longer life and more reasonable "brightness". While 3.3v works on blue and white LEDs, you can also go between the 3.3 and 5 to get +1.7v; perfect for a red LED. Also, you should not need that low of an ohm dummy load; 10 ohms makes several watts worth ((5v/10r)*5v) of wasted power into heat, which makes the fan run louder at standby. A hundred milliwatts (~240 Ohms on +5v) should make SMPS stable. Might be worth mentioning the voltage combos available by combining and diffing outputs: +7v between 5v and 12v, 8.7v from 12v and 3.3v, etc...
I always use current limiting resistors with LEDs. The purpose of using LEDs on the 5V standby and 5V power good lines are to use them as indicators lights. Technically you still need a current limiting resistor for an LED on the 3.3V line, even though the LED's forward voltage is close to 3.3V. I've ran experiments with white LEDs and noticed that they run hot and begin to have diminished output after running them for a while.
I went with a 10 ohm 10 watt power resistor for this and older builds because that's what I've seen used in several other builds. I find though that it's not needed in newer power supplies because the voltage is already close to being stabilized. From experience, the fans in these supplies are either constant speed, voltage controlled (based on the temp of the heat sink(s)) or PWM controlled (on better PSUs). If I do use a power resistor, I mount it directly behind the fan to quickly cool it.
I've mentioned the possible voltage combinations in other (newer) videos because I also noticed that I forgot to mention it. Thank you for your comment.
good deal, i'll check out the new vids. i just didn't hear anything about resistors and wanted to save the life of some poor 5mm red.
I'll put an annotation in the video if I didn't mention it already. Thanks.
The best tutorial i've seen on converting a ATX PSU to this day. GREAT JOBB!!!!
+Fredrik Johansson thank you so much!
Yea men u explain better than other videos that i watch good job bro.
Thank you, this is really useful! keep doing what you're doing!
I'm glad you found the video useful. And thank you for your kind words.
Wow, You just made a retired ASE Master Tech happy. Looking to use 12 volt dc stuff like a simple pump for solvent tank. I have 12 volt motors in all configurations and taught 6 electrical classes (And much more) but for a major car/truck company. Question: I have just started looking but what type of desktop computers have these?
I am sure the bigger the better. In Omaha, I know there are at least two computer recycling facilities but since this 2005 video watch in 2020, I will have to be creative. I would bet these have a large multiple tap transformer with circuitry to clean, smooth and filter any output. It's like a 1965 TV console with record player on one side and AM/FM high fidelity steel on the other. It's is in many child era memories for many as it took two men & a boy to move these. With multiple voltages required for different internal functions, most don't know about. Just love your clear spoken word, description and a slight Jersey accent, not anything bad by that. People said I had a little Southern accent, yes, living in NE, I grew up in KS so south yes! Like, subscribed!
Where do you find these? He said as my 10 year of disability happens this month. Can't wait for our hospitals to open Monday, as my Dr will call to schedule my 4th lumbar fusion in June! Great. All a result of a stupid bosses decision to take me out of the shop, away from my tool box, then run hand operated gas powered construction equipment for 5hrs in 1987 that destroyed my back. Yep, a guy who makes his living bent over fenders everyday. That's life! Thanks again and hope all is well as this crazy "WU-FLUE" got many freaked out. I have 12 years of stuff to do at home in my garage. Best to all!
well explained , wanted to understand the wiring , now I do . thanks'
Very helpful! Thnx very much. From the Netherlands
+René Kok You're welcome.
Thank you very much.The best explanation ever found about power supply conversion.Now I know what every colour stand for.What if there is no green wire.Which one do I use instead.
Your tutorials. Was really good
best explanation on u tube.
Thank you!
excellent video & well explained, Thank You.
+mick p you're welcome. Thanks for the comment!
Nicely explained!!!
Thank you very much for the video
How do you do? The video on making a power supply was very helpful. I also like the fact that you explain the information very well . I have a question. I have a Liteon model no : PS-5221-9 and it came with two brown wires. What do I do with the second wire brown wire ? All the other wires that you show are the same except the extra brown . I just subscribed to your channel and going to check out the videos you have . Hopefully you have time to reply . I’m not sure how that happens . This is the first time I comment or ask a question on CZcams. Thanks for time , again liked your video.
Thank you for your comment. I'm glad you found my videos helpful. I'm not familiar with the power supply in question, however, after looking at a few pictures of the same unit on eBay, I'd say the brown cables were used as the +12V connector for the CPU. There would have been two brown and two black together in a 4-way Molex plug. That makes the most sense as there were only three other connectors; two SATA Power and one Motherboard 20+4 Pin Molex. Thou shalt always check voltages - connect a volt meter between brown and black and see if you get around +12V. Hope this helps.
Thanks.
Very nice and helpful video.
Thank you!
Thanks.
I have also created my own power supply.
Thank you for this great information!
good video!! Thanks!! I'm making custom cable for my computer and I was worried about voltage drop. couldn't check it because I did not know how to get it to run without being hooked up.
Very good video on how to hack a PC power supply . I'm using it to power the accessory lighting on my HO train platform,
however the USB hook up as explained here is not enough to charge my iphone 7.
It will let you power up LED's!!
Thank you for your comment. Your mileage may vary with these power supplies. Some have a higher 5V standby supply than others and therefore some are more useful than others. I can charge my phone perfectly fine from the ones I've built but then again I only need a minimal amount of power to do so as I'm using a phone from 2010 that is as far from "Android or iOS" as you can get!
Thank you for this!
Thank you Sir v good and clear explanation Appreciated 👍
You're welcome.
Great video i want to make one to run my hf radio , cb radio power supply's are very expensive.
Do they use switch mode power supplies in the radio world? I'd think they'd be too noisy and that you'd want a linear supply instead but I could be wrong.
Thanks for the video , learnt a great deal . Did u mention what size resistor you use on the LED ?
I didn't mention it however you'll need to adjust the value of the resistor to match the forward voltage / current of the LED to the source voltage (5V). I use the LED Resistor Wizard Tool located here: led.linear1.org/1led.wiz
I follow your tutorial with some minor modification. I keep getting 2.77 volts out of the 3.3v. 5V out of 5V outlet and 12.99V out of 12V outlet. Wondering why. I do not use any additional resistors except one 330ohm on the green led with standby power setup (purple cable and black). any idea ?
Did you try putting a load onto either the 3.3v or 5v rails? If not, try that and see if it stabilizes. I'd also see if there's a trim pot on the board that you can use to adjust the voltage.
Nice
Excellent video.. why do many people say you have to set it up with a load on it tho.. seen people wire resistors to the red or yellow depending on which voltage is stated as the most amp heavy on the case.
Some power supplies need a load to stabilize the voltage but most of the ones I've done were stable enough.
Thanks sir...
As usual, I enjoyed your in-depth explanations. I did get a little confused on the purple and grey and exactly what they tell me. Do I have this correct: If Switch is ON, then Grey and Purple wired output LED's are ON. If I switch OFF, the AC light (Grey wire) goes off (indicates you turned the switch to OFF for AC power), but the Purple Wire LED which has the USB connector remains ON if there is a load. However, if there is no load on the USB connector, does the light go off? Not sure. Also, there eem to be about 6 to 8 ground wires (black)...but ground is ground (right?), so a single ground wire ought to ground all the positive connections if I am thinking right. Is there a reason why there are so many ground wires? Also for each LED, you need a resistor, correct? I have seen a suggestion of 320 Ohms on LED's on a moded PSU. What did you use for resistors on the LED's? Another consideration for safety are fuses...if you were to put fuses in line with each output, what maximum currant rating would you use? Overall, great explanation. You said something about de-soldering some wires from the circuit board, but not sure what you meant and there was no demonstration. I would have liked a better look on the inside of that PSU towards the end to give me a better understanding of what you did exactly. Overall, excellent...
The purple wire is active when the power supply is receiving AC power. The orange LED will light up and the USB port will become active. The PSU is in standby mode. When the toggle switch is turned on the power supply becomes active and the grey wire will light the green LED up. This is the "power good" indicator. When you switch off AC power the whole unit goes dead.
Ground is ground indeed however the wires are too thin to carry the current that each power rail can output. Hence, you need multiple ground wires. You can split them off and have multiple points.
You do need one resistor per LED and the value is determined by the forward voltage, current draw of the LED and the supply voltage. I used a 100 ohm for green and a 180 ohm for orange because that's what came with the LEDs and was recommended for a 5V supply.
If you use fuses, you would want to use ones that are rated for the amount of current you need to draw. So if you have a 5 amp circuit you would need a 5 amp fuse. If you wanted to protect a whole rail, you'd want a fuse that is rated for the maximum output of that channel. It may not be necessary though as many PSUs have over-voltage, over-current, and short circuit protection built in.
In another build, I removed the multiple smaller wires and replaced them with larger gauge single wires. Instead of two bundles of three 18 AWG conductors, I used one 10 AWG conductor for example. I will have more of these mod videos soon, so stay tuned.
Thank you.
See the followup episode here: czcams.com/video/fIcGMeWkaYI/video.html
Grateful for the sharing! and very good didactic video.
I followed his tips, but I got a doubt :( when using a combination of 5v + 12v I get 7v ... but the question is about the ability of amps ... I used an even more powerful source, which 5v gives me 25A and at 12V gives 18A (actually has 3 channels with 18A each) now the question is how I calculate the Amps at 7v ....
Would it be possible to help? thankful in advance;)
Do you need a load resistor or fuses? I see a lot of other DIYs incorporate fuses but I thought the PSU already had overload protection.
The fuse wouldn't hurt but isn't necessary as the PSUs have overload protection, as you mentioned.
I've tested several modern power supplies and noticed very little difference in the voltage output and decided not to go through the cost / effort of installing one. That said, I have added them to units in the past that had unstable voltage output. I used a 10 ohm 10 watt ceramic power resistor with a bit of aluminum heat sink attached with thermal adhesive compound.
What can you do with the -12V?How do you connect it.
Also how would I install the load resistor in the power supply itself?
please help, i tried to power on my power supply by connect green with black wires with a load but it doesn't work . i tried this way on other two power supply the same thing happening.
So could you wire a 2 prong toggle switch on the green wire so I can control power to the motherboard using said switch? I know you said I have to wire the green and black to a switch but can I just use the green only?
How about a variable supply using a Thermaltake Toughpower 775watt? Having issues.
Did you use any buck-boost converter to connect the boom box with the 12v line as it outputs a lot of amperes..
i want to charge my car bettery with computer power suply. But in power suply there is a yellow color wire having voltage is 12v thats ok,,, but ampere is low as about 1ampere to 2ampere only (which is not suffient to charge my car bettery). My problem is that how to increase the amperage of (yellow 12v wire) so that it charge my bettery easily.
regds,
thanks. plz reply in detail to solve my problem
Good price too
why does power supply shut down when connecting a 12v and 5v to the supply??????
Thanks great video
Can u make 12 volt car charger out of it
Thanks for your comment. I don't have experience in using one of these to charge a car or any other battery however I'd say while it might be possible, I wouldn't recommend it. The voltage would have to be higher than 12V and the current would have to be regulated to safely charge a battery. You're better off finding plans to build your own charger that has a nice beefy transformer and good voltage / current regulation.
show in schematic diagram the exact connection of green,gray, vio, wires to START the ATX PSU !
Hey, did you use a resistor for either of the LEDs?
Thanks
You're welcome.
thank you! sorry this is kind of new to me, I plan to use it to power an old car radio to play cds and maybe turn on some led strip lighting for the work bench. you recommend just using yellow and ground wires to do this? thank you again.
+Jorge Bermudez the yellow and ground wires will get you 12v.
Jorge Bermudez Tsaid
Ok how do we go about obtaining one of these jems??
Would LOVE 24v 750w and at least 30amp.
What's the price.
I have a DC pump that I use for pumping oil. do you think I could use a computer power supply to run it? I figured since it hooks up to my 12v battery that it might work with the 12v power supply. it uses 13.5 amp. I have an old AT power supply that I want to try. it has an external on/off switch with a white, blue, brown and of course black for ground. wire harness has Black (ground), Yellow (12V), Red (5V), Orange (Power Good), Blue (-12V) and White (-5V) I believe. does this sound correct? do I need to put in resistors for an AT power supply? ty for your assistance. 🙂
Orange is usually 3.3 volts. The external switch sounds like it's 120V AC in which case black is HOT and white is Neutral. Please verify this as they are different than what I show here.
Otherwise, this may or may not work for your intended application, as these power supplies are temperamental and sometimes trip the overcurrent protection with large inductive loads like motors.
If this is an older ATX power supply, you may need a resistor as you mention. The best way to know is to check the voltage output with a meter and see if it there is a big change when you start to add a load.
@@pileggitech great and thanks for the reply.
Sorry if I missed it, but did you do a boom box video. Thanks
My power supply don't have green wire to turn it on?
Are you starting a store in partially finished home made power supplies?
This is a great video Pilegg..... is there any way to modify into this idea a variable pot
There is a way of doing that it is more efficient to use an active circuit over a pot. I used an "adjustable buck converter" in another build that you can see in the beginning of this video: czcams.com/video/SK4GKYi3Wm0/video.html. I featured a couple videos on the build of this particular power supply but I don't really have a final review video of it.
Hi there, when I connect the leds to the purple and black wire the led is burning out, any idea why
Are you using the correct value resistor between the LED and the purple wire?
Don't you need a load on the 5v rail?
sir, I want to thank you for this video and I am very newbie to this electronic stuff, am trying to tech my self, so i want to ask you this, i have power supply labeled "RED 5v 18A" does the 5v red wire will give 18A ? and what if i want to charge my phone with this 5 volt will it kill my phone because the high ampere ? and what if i want to connect a LED to 5v wire ? the red wire ? .. im confused ... and sorry for my poor english
Don't worry your English is great. Yes, the 5V line should put out 18A max. You should be able to charge your phone without issue (it should only draw the current that it actually requires). You'll need a current limiting resistor in line with the LED to safely power it since the LED doesn't have any internal way of regulating current draw.
i just finished my power supply project .. i follow your lead .. and i use 5v rail to charge my phone but when i connect my phone to charge my phone using usb tester "voltage and current reader" it says 5v 0A .. no ampere output at all. do you think i have to use a dummy load ? thank you for the replay
Usually you only need the dummy load to stabilize the voltage, which looks like it's OK. Is the battery already fully charged?
No the battery is empty 10%, i will link a picture for you, ibb.co/nbGYRF
i fix it, thank you sir, it was my phone not pulling any current, i tried another phone and its charging .
101%ok
+Benjamin Alvares thank you
Will using a potentiometer as the switch reduce the voltage
No. The switch used here is only a signal. You could use a potentiometer in line with the voltage closest to the one you need to "dial in" a lower voltage but the resulting heat would be problematic. The better tool for the job would be a "buck converter".
can I use a red wire for the stby led.. and use the purple for the USB connection?
If you use the red wire for the LED, it will only light up when the power supply is on, not when it is in standby. The purple wire is the standby supply and is perfect for a USB connection.
i bought a power supply on ebay to power 5 80mm fans and a couple of blue 40mm fans, i left the connectors intact because the fans plug right into them, this ATX supply has a switch built into it already from the factory, so i took the black and green wire and jumped them together, when i turn on the power switch all the fans turn on but only for a minute then the power supply turns off, what else do i need to do? Do i actually need to add another switch and led's as in your video?
The switch on the back of the PSU (near the power cord) will switch the actual AC power on or off. The switch I added in the video is between the green and black wires, which you jumped together. This switch takes the PSU out of "standby mode" and puts it into "run mode". Normally you would flip the AC switch first and then the standby / run switch. Are you leaving the green / black wires connected? Other than that it sounds like everything is right, unless you either have a bad PSU or you don't have enough of a load on the PSU to keep it running (unlikely).
i will add a switch between the green and black (neg) ground wire. I will let you know what happens ok, Thanks
ok, so i installed a switch and led on the red 12v line and one on the purple wire which im told is the standby , so i turned on the power suppliy power switch and both the led's lit up, not sure why both at the same time, it has a built in fan, but it did not start, so i clicked on the switch i installed and nothing happend. I hate being defeated, it could be the power supply is bad or something i missed, so i was wondering if i can just buy one from you, l hate giving up on it but i already have $30 into it. All i need it to do is power (7 ) 12v case fans 5 80mm and 2 40mm fans thats it. I do like the ones you sell, but without the test leads, i like the one on your shelf with the terminal block, i can connect my fans and led's to it. Help me out.
Can you send me a picture of your wiring job? That will help me to help you better. You can always send me the unit and the parts and I'll gladly finish the job for you.
Desmo Valve samething happened to me.I shorted green and black wire and it ran for few minutes then walaaahhh.
Power supply:IM OUT!
can you actually use a 12v battery 100ah on this to power the house
Unfortunately, no. You need an inverter for that.
Hi Sir! Do I necessarily need a resistor or load for making one? Thank you very much!
+DaNerd 12 I'm assuming you're asking about the power resistor. Most of the newer supplies I modded didn't need one. The best thing I can recommend to do is mod your supply without one first. Check the output voltages with a multimeter to see if you're getting the correct voltages. Then apply a small load to each power rail and check the voltages again. If they were to high or to low before the load was applied but then stabilized after applying the load., then you'll need the resistor. If the is no or little change, you should be fine without one.
Thank you very much. Will surely follow your tips! :)
You're welcome.
Nice job what's the amp output
So you don't really need a 10Ω 10w Resistor on Red (+5) & Black (GND). Because I heard the PS needs a load to stay on, idk. Good video. I have all the parts, because I made one already, but I fried it. I'm going to make another one here in a couple weeks, but just wanted to ask. Very good video quality, thanks for sharing.
It seems like it depends on the actual power supply; the newer ones seem to be more stable. I think the resistor is used to stabilize the voltage, rather than keep the unit running. I've had older PSUs not put out the correct voltages unless the resistor was used. I've also heard that you need a resistor on the +12V and the +5V rails however I haven't confirmed that. I have actually attached a modest load to the +3.3V rail and have noticed that the voltages seem to get closer to the rated voltage. I guess your mileage will vary.
Pileggi Technical Services So this is pretty good then? I drew this up in InkScape to better understand how it's all wired. I actually made one already, but I fried it, because I touched metal to one of the wires or something. It was a cheap one. I'm going to make another one, but this time it's probably going to be something like a EVGA 430 W1 80+ from Amazon. Thanks for the reply. I'll try it without the 10Ω 10w power resistor on the Red and black, and test the connections with my 6000 counts dmm, worst thing I'll have to do is use one of the resistors I got from Mouser Electronics.
imgur.com/EGgjXnA
Nice graphic. I have come across a couple units that also had a +5V sense wire too. I believe it was also red. You can connect a resistor and LED to the PWR GOOD lead as an indicator. I've also installed a USN port on the +5V stand by line as well. A good PSU should come with over voltage, over current, and short circuit protection.
Pileggi Technical Services Thanks for the compliment on my drawing. Thanks again for the help with the DIY PSU wiring. Subbed & +1
Thank you!
sir help me , what if we do kot hve brown wire to connect with 3.3v wire?
not*
Not to worry. Some power supplies have it and some don't. Sometimes it's orange too.
Where do I get one like the black one with the USB
I built it! I'm holding a giveaway contest for it too. You can see the video here: czcams.com/video/0OrpoNDp0mE/video.html
still have them for sale?
No, they weren't cost effective enough. It's more of a novelty / fun DIY project to do than a profitable item to sell.
Where did you acquire the USB port?
Look for a "USB 2.0 Bracket" such as this: goo.gl/NgTI6U. I just used one of the ports from that. It even has mounting ears.
Great idea. Didn't know where to get one with the mounting ears.
Thanks for the expert help and the great video's!!
An thank you for watching my videos! You can also use a USB 2.0 Panel Mount Extension Cable like this one: goo.gl/sEYVWE
do you have any of the power supplys left
At this time I don't. I am planning on having some for sale in the future, just not sure when.
i got question i have two plus 12 v i need to get 13.8 v is a boost converter be enough i found one that has the 5a rating i need but will it work to connect 12 v to 13.8
That should work. I'm pretty sure you can find a boost converter that can handle 5A in that voltage range. Stepping up to 13.8V from 12V shouldn't be an issue as far as efficiency / heat is concerned.
i just thinking about a cb and it has to be 13.8 but i have a dell atx and it has two plus 12v on is a 12v a and the other is b how odd never seen that
Some power supplies have multiple 12V rails. There are reasons / advantages to having separate rails, although I'm not sure why off the top of my head. I have heard thought that you can still combine them into one rail however I haven't tried that myself and as such I'm not sure if it will work or not.
How much for power supply
I don't have any new ones at the moment to sell. However I can modify one for you for $50 plus return shipping if you send one in to me. The cost includes the parts and my time. I can either modify a new supply or one that was pulled from old equipment. Feel free to email me at Pileggitech@gmail.com if you wand to go over the details.
Pileggi Technical Services sir i want to ask, what if we do not hve brown wire that suppose to connect together with 3.3 v wire ?
You should just make a box with banana connectors and a female atx connector and a switch and just plug it in to the power supply . waste of time pulling it all apart like this , the psu is old and will fail at some point , all you need to do when it does is swap it out and plug in another one . or just buy a 10$ desktop board www.ebay.co.uk/itm/like/331604839585?lpid=122&chn=ps&adgroupid=13585920426&rlsatarget=aud-133395220626%3Apla-142405549746&adtype=pla&poi=&googleloc=9045088&device=c&campaignid=207297426&crdt=0
David Haney true. I can just buy a board and plug it in to the ATX connector. You can't utilize the full current output that way. In fact most of those devices have fuses installed which are rated much lower than most supplies are rated at. And yes, most people mod old PSUs, they also mod brand new ones too. I've had one running under load for close to a decade now and it was over five years old when I modded it. They are subject to wear just like every other device out there and wouldn't necessarily wear out faster because they are modded.
yeah the current draw is an issue with the shop bought ones . I made mine so I can use the full current draw , not that I ever get anywhere near it , and you are right i`ve had mine a few years now but i decided to make mine because I can have the psu under the desk out of the way and have the break out box on the desk which has a much smaller for print to is as i`m limited on space . Either way work great tho :)
Too much talking on introduction.. 😁😁😁
Can we short -12 and +12 for 24v?
@@chongshenchang9367 Seriously? A complaint AND a question???
First off fast forward exists for a reason... LOL
Second, yes, you can get 24 between -12V and +12V however you won't get much current as the -12V rail isn't very powerful.
@@pileggitech 😂😂😂😂 Thank you Sir..

This is the first time I comment or ask a question on CZcams. Thanks for time , again liked your video.
