GENIUS! It was lucky that it worked and did not puff! The board of such power supplies is multilayer and under the + 12V polygon there is usually a ground polygon. And when drilling and screwing on the clamps, we get a short circuit, well, or a beautiful fireworks display with an abundance of smoke and sparks!
What a great idea & result - love the wrap, just makes a project look more finished - Good work bud. But 4 likes at 103views - that's pretty piss poor people - this type of stuff takes time and effort to share SO SMASH the like button!
Thanks mate, Top Tutorial, I've been waiting for one on Server PSU's as opposed to ATX one's and I can't believe how easy it is. You don't even have to open it up.
I'd recommend tinning the tabs to give more path for current to get to the plugs. I guess you could check the joints with a heat camera at a high load to see if you're getting bottleneck resistance there. I just soldered half the 4 guage wire to the top pad and half to the bottom on both sides full-length. Watch out for some of these, they have current-drawing voltage doublers (you'll notice they can work at 220 V, ) that can be very hot when plugged in and not turned on.
I thought about that when I first built it, then later decided, I would probably never max it out. I bet the most I would use is close to 300- 400 amps. So I decided to just try bolting them on. I must have gotten lucky with this one, I have not had any issues with heat, loud fans or spikes/drops in voltage. I like this build so much I went with the bigger brother 1200watts(at 220) and ran 2 in series for 25.2V. Unfortunately, my home can only draw 120. I'm not sure if it is because I purchased them all brand new, but those I have also had no issues yet. The crazy thing, is I hardly find myself using either the 750 one here or the 2 in series for the 25.2V. I actually have a pretty cool part 2 video, where I created a circuit that makes sure to protect each one from a power loss. That video ended up much longer than I anticipated and I have yet to edit...LOL I have a friend who asked me to build him one of these, I may try the soldering on those like you mentioned. I think on those I may also use bullet connectors instead. Thanks for the tip and the comment and I really appreciate the sub!!
@@njfulwider5 yeah I heard "watts" after 300-400. {:-) any bottleneck resistance would show as heat and any bad bottleneck resistance would glow red, so you're probably fine.
@@snap-off5383 the power supply can operate at max capacity at 220v. it doesn't mean it outputs 220v plugged into 110v outlets in america. the most he will see is 12v
@@blue03r6 when the power supply is plugged into 110 it uses a voltage doubler circuit to double the voltage up to 220 before it converts it to DC and when you plug it in to 220 obviously it bypasses that, that's what I was talking about. When plugged into 110 that voltage doubler circuit draws current and makes the power supply rather warm some of them even have little heat warning stickers on them.
@@snap-off5383 I don't know about what you just said. i'm not an engineer. however it is widely known that servers power supplies are grossly overpowered. this causes them to run hotter. because the psu is not running at an efficient rate and the wasted input power becomes heat. seems counterintuitive that a psu running closer to it's max capacity runs cooler.
Had to let someone go first this time :P.. and had to be Joe of all people.. BOOM! what's going on bro. planning some scheme on the side and surprise us with a video ey? Every damn project I try to do ends up with a blocker with some major issue or needed parts. grrr. plus lost my camera.. Doh!
Phizicks, Keep in mind, I am always a hop jump and a skip away. You never know if I have any extra parts laying around I could send you. With USPS, usually intercity is 24 hours, and sometimes 48. I can't believe I am just now finding these....HOLY Cow, these would have saved me a lot of time and trouble!! Thanks for commenting Joe!
LOL. Oh Ive been out of town to my brothers wedding and a quick visit to my parents and just got back into town the other day. Im super behind for videos . Oh aaaaaand were super busy at work right meow too🙄
Hey Joe, it's me Tag n Charlie from the powerwall group. I modified a hstns pa01 for my 1000w 10s Icharger, gets 74a on 110v 910w, or on 220v it pulls 106a max and 1300w, I also have a smaller and quieter hstns pl04 550w for smaller jobs
ooh fun, I made a 24v 1100W server PSU mod, I totally over engineered it, but it works really well. I even used the OEM server connectors so if I blow one up then I just have to swap it out (since I have like 8 others lol) though of course it needs an isolated one for the 24v so it isnt just plug an play any two server psu's
Thanks! If you see some of the videos I did using this in later videos, I also added battery stickers and it made it look even cooler! Thanks for watching and commenting 👍👍👍
Was drilling the holes in the pad problematic at all? I don't know a lot about how these pads are constructed but my fear would be its something like a multi layer PCB board and something would go wrong if you drilled through it but it appears they are just power and ground pads so no reason why they would be multilayer. If you haven't had any issues then I'll probably give it a go. The 460's are $10 a piece and I have a spare one. I recently found the 1200SB's for $19 shipped and might grab a lot of them.
It's been awhile, but I don't remember there being any issues. If I remember correctly, the only issue I had was the bottom nuts on the bottom of the power case would sometimes get stuck and spin, but still came out after. But I don't believe I had the issues you mentioned. It was a long time since I did this video. Pretty sure once I taped it up so no small pieces went in the componits and short it out. I just drilled the holes starring with a tiny bit and working my way up slowly till I had the right size. No issues. I've also seen it done without holes, they just layed the plugs down and soldered on. I'd use Google and you'd be surprised how many different ways there are to do it. I also did a 24v version, but I need to edit part 2 of the video
the vynil makes everything look nice! you could make an XT-60 distribution bus so everything can hook up to it, i would recommend fusing for your small chargers because 63A means it will not trip if there is a short since 12v over 0.3 ohm wire is only 40A soo it will just cook, though I think there is smart circuitry that senses what a short is and what is a full load. maybe a test is in order ;-)
Your right! I just went with the same server model they sell with the Isdt Models. Only Difference, they don't use the resistor and they only have 2 x 10 gauge wire with an Ext60 connector. Ohhh, and pretty little stickers. Been working pretty good so far with the 2 chargers, 2 xtras and my Ternagy also. I have 2 of the DPS 1200W(900w) to mess around with also.
If you look at the Power supply you have the pins are numbered, and in the video, it will tell you which numbers to attach the resistors. As for the holes, I just simply centered them on the bigger pads. Some of the other DIYers prefer to solder their plugs on, I just thought this might be easier.
Hi! nice video, work this also for a HP DPS 800-GB psu ? and do i need als a resistor ? if yes wich one ? I want use this to charge 2S li-po's for car RC.
Unfortunately I don’t have any experience with that model, but I did a little research and found a video that should help👍👍👍-ruclips.net/video/qDeLH6yzlbw/видео.html
Hi, I got my hands to 2 of this HSTNS-PL18 Rev 06. But I have some problems when reading the voltage after I solder a 510ohms resistor, the voltage just goes up to and it does not stay around 12v, it keeps going up even to 16v ... and it is the same for both of them. What I am missing?
That is really strange. I don't think the resistor matters as long as you use 560 to 1000ohms. You might try and add a 1000ohm(1k ohm). On the ones I have the 2 HSTNS-PL11and this 750watt version, the voltage was around 12.3-12.4 steady. To get anything higher I had to adjust as you see here-ruclips.net/video/dnD-zaOznRo/видео.html. But I could never get anything over 13. I guess there are some hacks out there to add capacitors and resistors in certain areas of the board, but i have never attempted. If Im not mistaken, when I got mine, the seller claimed these were brand new? But you know how ebay can be. What happens when you add a load? does the voltage drop to 12.28ish? I had another viewer tell me he had a major voltage drop and he had a strange ringing coming from the power supply.
Hi. I tried to increase output voltage up to 13.8. For that purpose I shorted SMD resistor, but PSU lost their output voltage at all. I think that overvoltage protection save some data to the controller. Maybe you know how to reset it?
If I remember correctly, I tried this also on a psu and shorted something. I couldn't get it over 12.8V. But there is a video, the guy did some mod to the electrical board with the potentiometers and got it up that high. But I'm not sure what the video name is. Sorry, wish I could of been more useful.
Thank you for the video. I am getting ready for the hack. I have a HSTNS Pl-29. Will this modification apply to my model too? And i have a 390ohm resistor, is this sufficient?
I’m not familiar with that model, I assume if these look the same, the pinouts should be the same. If 390 ohms don’t work you can always try something bigger. I hope it works out for you! Thanks for commenting 👍👍👍
@@njfulwider5 Thanks man. I just tried this and I am getting 12.3V at the output. Just need to put some load to see if everything stays fine. Great tip and love your finishing on that👍
What kind of voltage drop do you see under load? I got one of the pl11 models and bridged pin 32 to 36 and under load the fan slows a bit and voltage sags half a volt at 20a is that normal? Also runs a bit warm at idle
I use this pretty much each time I use any of my ISDT Chargers. Almost every day. Even at full load, it seems to run pretty cool. At idle, I see no temp difference. Unfortunately, I have not tested for any voltage drop, the ISDT says it's running at the voltage I set it at when I put this together, But that is only charging series batteries(you never really see it run at peak).
I use my t8 with it I found out about the sag when it game me a voltage less than 12v error. I ran it today at 16a which is max my isdt would do with 6s on 12v supply. It got warm but not hot maybe it was just me, but the voltage still sags I opened it and turned up the pot to 12.75 which is max but it still got down to 12.2 at 400w 16a
hp dps 800gb , men I buy one of those and put it a resistor to 32 to ground like others video clips and what happen was it blows something inside ,it hurt me because it was brand new ... first I put the jumper and the resistor and plug to the outlet and the light ,don't the start ,but the fans work , I take Out the resistor and star great but in 2 min blows inside ...the damage was done ,...
hi, a friend told me he tried to do something like that and brought it to me to repair, schematics and diagrams by chance? there are components that exploded, they cannot be read. Thanks o_O (y)
great video, some information, I bought the same model of power supply from ebay, I don't know if it is defective, not having an identical model, I will describe what happens, if I load a 300w medium absorption rx580 video card, I hear a strong internal electric hum and normal? then without any boot board connection, i just apply electric plug it starts the fan starts automatically, is this normal?
I've heard of this with the lower power ones, but I'm unsure what problem they had. I've purchased 6 of these(750-1200w) and 4 used in projects, but I haven't had and issues with them. These are probably the cheapest bang for your buck, when it comes to power supply. Think another Diyer said these are running around 20-40$. Wish I had more information on these, sorry.
@@njfulwider5 thank you very much for your experience, yes it is a 750w, it must push an Amd RX 580 video card at full capacity I have verified it should absorb a maximum of 350w, this power supply model as soon as I start a game this electrical noise starts, I try to attach a uploaded video on google drive to let you understand the noise it makes. drive.google.com/file/d/1M-B59olAQisHTEYkVlfvKz4-Wf15Z-FJ/view?usp=drivesdk
@Lorenzo Vene sound like it could be the fan or a defective relay. That's not A sound you'd here from the curcuit board. Almost sounds like the relay is kicking on and off super fast. Or the fan speeding up because of a temperature change.
@@njfulwider5 thanks for your availability and your experience in the field, no I assure you it's not the fan, indeed it is very silent, until I activate a load, for example the rx580 video card at low speed normal operations example video and navigation does nothing, as soon as you start a game that noise starts and lasts for the entire game time, it stops as soon as you exit the gaming session, the video card I have seen the characteristics at full capacity does not exceed 200w, being a 750W it should not in the least affect this small load .
Yes Sir!! They do very well together.....But you need to make sure one is Hacked like my second video on these types of supplies-ruclips.net/video/dnD-zaOznRo/видео.html
Steve Vakalis forgot to mention, did you see the 90v 20 amp adjustable charger I made? I added the power switch the same way on that build as I also used a server power supply like this 👍👍👍
Good Question! When the Power Supply is inside of a Server, the 2 pins are what tell the unit to power on. The resistor does the same thing. Without it, the unit will not Power on at all. If I remember correctly, one side of the pin is Power on, and the other is 5V standby. Thanks for commenting!!!
njfulwider5 Say I have a different PS (I have the DPS-750RB). How would I determine if the same pins you used in this video are the one's I should connect a resistor to on my PS? Hunt for 5v with my multimeter with it plugged in? Have an email to chat about this more?
Jon Westberry I've been a little illl lately, sorry for the late response. Most of the Dells PSU like this have the same pinout for it. I personally just looked up the Model of Server supply and added Hack to it. This was the pin most of them used. I guess its the same pin that tells the server supply to start, powered by the 5V stdby pin.
@@njfulwider5 can you bridge the 2 pins use a wire not a resistor? I saw other vids just direct bridge the 2 pins together, what's the advantage to you a resistor?
I personally have never had one of these supplies, but I found this post on others who have and how they hacked it-www.rcgroups.com/forums/showthread.php?1695879-HP-Power-Supply-DPS-430DB-A-Conversion
I tried looking up the PSU, but I only get pics of the backside. If its a PSU like the one in the video, that connects to the same type of server. The pin should be close or the same. If its the other type. Jehu has a video of a hack he did. Wish I had more info,
njfulwider5 I soldered an 1k resistor on. But it has no output voltage. Do you know what the Problem could be? I connected a Brushed motor to test it but the motor didn’t spin. And I know for sure the motor runs
@@thediydude4110 I think you can hack these boards to give up to 15v or so, but the easiest way is to get a DC to DC converter to alter the voltage up or down to what you need (buck or boost). That is how i am going to use mine to create a kind of desktop power supply. It depends on your needs, but at least that way it doesnt risk me screwing up the power supply, just the converter, if it comes to that.
I have heard that some of the used models or server PSU that been used for a long time, tend to whine. Luckily the one I got is pretty newish. The fan is pretty easy to swap out if you find a cheap one online.
The highest I could get any of them was around 12.9V. But I have seen a few video's awhile back where another guy did something to the control board to get a higher voltage. But I watched them a long time ago and wasn't really sure what I used to search.
I need to have a couple of other versions at 12.6V for charging 18650's or other liIons. If you watch this video here- ruclips.net/video/dnD-zaOznRo/видео.html It shows how to adjust them. This one is adjusted the same way. I've been searching for the video of the other guy, but I can not seem to locate.
GENIUS! It was lucky that it worked and did not puff! The board of such power supplies is multilayer and under the + 12V polygon there is usually a ground polygon. And when drilling and screwing on the clamps, we get a short circuit, well, or a beautiful fireworks display with an abundance of smoke and sparks!

Thank you for your precise video documentation. I just fixed my PSU and it works fine. After soldering it directly had 13.5V, exactly what I wanted.
I love these PSUs, I use them on just about everything. I also used one on an bike charger 90V 20amp....So cheap for big performance!!

hi, a friend told me he tried to do something like that and brought it to me to repair, schematics and diagrams by chance? there are components that exploded, they cannot be read. Thanks o_O (y)

Hi great job but here a challenge to you. Can you hack a hp-dps 750ab-3 to 14.6V?
great video, some information, I bought the same model of power supply from ebay, I don't know if it is defective, not having an identical model, I will describe what happens, if I load a 300w medium absorption rx580 video card, I hear a strong internal electric hum and normal? then without any boot board connection, i just apply electric plug it starts the fan starts automatically, is this normal?
I've heard of this with the lower power ones, but I'm unsure what problem they had. I've purchased 6 of these(750-1200w) and 4 used in projects, but I haven't had and issues with them. These are probably the cheapest bang for your buck, when it comes to power supply. Think another Diyer said these are running around 20-40$. Wish I had more information on these, sorry.

thank you very much for your experience, yes it is a 750w, it must push an Amd RX 580 video card at full capacity I have verified it should absorb a maximum of 350w, this power supply model as soon as I start a game this electrical noise starts, I try to attach a uploaded video on google drive to let you understand the noise it makes.

with 850w power supply, only the noise of the fans is heard

@Lorenzo Vene sound like it could be the fan or a defective relay. That's not A sound you'd here from the curcuit board. Almost sounds like the relay is kicking on and off super fast. Or the fan speeding up because of a temperature change.
@@njfulwider5 thanks for your availability and your experience in the field, no I assure you it's not the fan, indeed it is very silent, until I activate a load, for example the rx580 video card at low speed normal operations example video and navigation does nothing, as soon as you start a game that noise starts and lasts for the entire game time, it stops as soon as you exit the gaming session, the video card I have seen the characteristics at full capacity does not exceed 200w, being a 750W it should not in the least affect this small load .
Nice 👍🖖
Don't block the air flow
THANK YOU
Do you know if you can combine 2 of them and make a 24volt power supply?
Yes Sir!! They do very well together.....But you need to make sure one is Hacked like my second video on these types of supplies-ruclips.net/video/dnD-zaOznRo/видео.html
Oh ok awesome, thank you
please tell me how to get it working (server dell DPS-500RB A) thanks
Hi where did you get the bullet connectors from?
was an eBay purchase I made a few years back.
Hi mate, I just wanted to know how to connect a toggle on-off switch to mine if you could help me? Thanks
Just connect the break at the resistor. 👍👍👍👍
@@njfulwider5 Thanks heaps buddy.
Steve Vakalis forgot to mention, did you see the 90v 20 amp adjustable charger I made? I added the power switch the same way on that build as I also used a server power supply like this 👍👍👍
What's the purpose of the resistor? I haven't seen that on other vids.
Good Question! When the Power Supply is inside of a Server, the 2 pins are what tell the unit to power on. The resistor does the same thing. Without it, the unit will not Power on at all. If I remember correctly, one side of the pin is Power on, and the other is 5V standby. Thanks for commenting!!!
njfulwider5 Thanks!
njfulwider5 Say I have a different PS (I have the DPS-750RB). How would I determine if the same pins you used in this video are the one's I should connect a resistor to on my PS? Hunt for 5v with my multimeter with it plugged in? Have an email to chat about this more?
Jon Westberry I've been a little illl lately, sorry for the late response. Most of the Dells PSU like this have the same pinout for it. I personally just looked up the Model of Server supply and added Hack to it. This was the pin most of them used. I guess its the same pin that tells the server supply to start, powered by the 5V stdby pin.
@@njfulwider5 can you bridge the 2 pins use a wire not a resistor? I saw other vids just direct bridge the 2 pins together, what's the advantage to you a resistor?
Does anyone have the fan pinout for the fan in this power supply? I'm trying to retrofit quieter fans in my server.
i have hp dps 430db .. can u help me how to jumpstart it ?
I personally have never had one of these supplies, but I found this post on others who have and how they hacked it-www.rcgroups.com/forums/showthread.php?1695879-HP-Power-Supply-DPS-430DB-A-Conversion
where do you find the red and black connectors? Part#? thanks!
I purchased those around 4 years back from a China supplier. I got like 25 pairs for 5$. Believe at the time, I just searched Banana Jacks.
has anyone attempted to communicate with the ps with the PMBus protocol?
Sir can you help me how to power on ph1400 w power supply Dsp-1400CB
I tried looking up the PSU, but I only get pics of the backside. If its a PSU like the one in the video, that connects to the same type of server. The pin should be close or the same. If its the other type. Jehu has a video of a hack he did. Wish I had more info,
HP dps750rba is this the model number of this PS
Yes!! I believe so, its been awhile since I built it
Do you think a 470 Ohm resistor would work too?
If it doesn't and that all you have you can use 2 in series to get 940 ohms
njfulwider5 thx good idea
njfulwider5 I soldered an 1k resistor on. But it has no output voltage. Do you know what the Problem could be? I connected a Brushed motor to test it but the motor didn’t spin. And I know for sure the motor runs
you can jump those pins with a wire, you don't need a resistor.
Hi thanks for the video I have a delta dps-600sb psu.
Does any one have the pinouts for it thanks.
Unfortanly I'm not that Familiar with that PSU?
would a 560 ohm resistor work? does the value matter?
I did a lot of research and 560 should be fine. I think you can go higher than 1000ohms
@@njfulwider5 What size do you use? thanks.
@@thediydude4110 510 ohm
njfulwider5 can you increase the voltage on this one and how high?
@@thediydude4110 I think you can hack these boards to give up to 15v or so, but the easiest way is to get a DC to DC converter to alter the voltage up or down to what you need (buck or boost). That is how i am going to use mine to create a kind of desktop power supply. It depends on your needs, but at least that way it doesnt risk me screwing up the power supply, just the converter, if it comes to that.
can you draw up to 40A on these banana sockets??
What is this
I have that power supply and it whines under load is it normal or bad?
I have heard that some of the used models or server PSU that been used for a long time, tend to whine. Luckily the one I got is pretty newish. The fan is pretty easy to swap out if you find a cheap one online.
@@njfulwider5 Its not the fan though its only under above like 5 amps
@@thediydude4110 Sounds like it maybe one of the small transformers maybe.
@@njfulwider5 do you think its bad?
how many watts does the resistor need to be?
I think 1/8 watt is fine because the power on signal is nearly nothing.
How to increase the voltage of the PL-18 to 13,8 v ? Anybody can help me ?
The highest I could get any of them was around 12.9V. But I have seen a few video's awhile back where another guy did something to the control board to get a higher voltage. But I watched them a long time ago and wasn't really sure what I used to search.
how do you have had 12,9V ?? wiht the poti ?
I need to have a couple of other versions at 12.6V for charging 18650's or other liIons. If you watch this video here-
ruclips.net/video/dnD-zaOznRo/видео.html
It shows how to adjust them. This one is adjusted the same way. I've been searching for the video of the other guy, but I can not seem to locate.
Use a DC to DC converter....the easy way.
ruclips.net/video/4P1-lpzYV1Y/видео.html this guy got 13.85 same supply
You need a 3d printer.
That is for sure!!! Maybe sometime soon!!!
the fans are very noisy.
when they do turn on high, they're like airplanes props. quite loud.
