Thank you for this video. I have been looking for a way to utilize my DPS-750RB without any luck. You are the first one that provided the correct resistor value (470ohms) to allow my units to operate properly. Keep up the good work.
I didn't mention it in the video, but the auto-start modification works by using the 5V standby line (pin 32) to charge te 100uF cap via the 470ohm resistor. This provides the necessary time delay before the charge is sufficient to tun on the NPN transistor and the supply.
Hello I have one question there is possibility for 24 pin connector to motherboard ?
But the sticker says +12VSB (not +5VSB)..?
I have the same model (HSTNS-PL11) Just a jumper wire with no resistor, power cycled multiple times short and long periods it always turns on with 12v out.
Ya, of all the vids I've watched, this is first guy that says it won't turn back on without removing the resistor. May just get a breakout board, as I like the on-off feature most have.
I tested this circuit using a C1815 transistor. Worked perfectly.
And just realized I used a 470kohm resistor.
I have been modding the supplies for a long time and I've never heard anything about this time delay requirement??? There is also nothing in the official datasheet about this. I'm not sure where OP got his info but this isn't the correct way to power on this unit. The normal 470ohm resistor between pin 1 and 4 is also not spec, but works okay for some models.
The proper, manufacturer designed method is:
1: Tie pin 1 (left-most pin on top side) to ground.
2: Connect pin 4 to +12v through a 21k resistor (the 200mA +12v standby is always on with power cable attached. Probe the top pins to locate it). You can also add a power switch in that line if you need one.
3: That's all! Output is a steady 12.23V on every one I've used and it will not drop much, if any with heavy load! This is one of the most well regulated, and highest performance 12v supply I know of. I make heavy use of these for all kinds of things including my 24/7 high power servers for which they were originally designed.
NOTE: I like to add an LED from pin 3 to 1 that will light when output is activated.
Also, these units get very hot at high loads (or even no load) because the fan runs at near silent most all the time. They are designed to run inside a server with 6x 200CFM Delta fans blasting air into them. To fix this, you can mod the internals in various ways or, what I am working on right now, connect over I2C to the PMBUS interface and send commands as needed to monitor/set the speeds/temps. Ill be posting a guide online once I get time
UPDATE: I have two different types of the official breakout boards for these supplies. Both are designed differently, both wrong according to official datasheet, yet both work. However, I have noticed the onboard fan speed control acts differently between all these methods. My method (the official one) has a very smooth/fast increase in fan speed as needed in relation to internal heat. The others seem slow to respond and on some versions of this PSU, the fan never changes even at full load. Because of this, I strongly suggest using only this official method and avoid the breakout boards on eBay/Amazon as they use VERY poor designs (direct shorting of many unreated pins. Insufficient copper to handle full loading)
21K resistor but what watt? I have noticed that a lot people list resistors and leave off the watts. Do you have a video of your method? Thanks, Todd.
no video, sorry. It's on my long to-do list tho. The official datasheet doesn't specify watts of the 21k. Probably because it's very minimal with no real current passing through this sense line. I just use whatever 20k-22k resisters I can find in my scrap pile and it works.
Hi, can I ask if this method will work with HSTNS-PL28, 460W, still common slot PSU ?
@@nikolaykarpuzov5320 I too need the answer to this??
I play with these all the time and made a few hack videos. I think the little hole on the side of the unit is awesome!!! I wish I would have thought of that when I modded mine. But I can go back and fix. Great Video!!
I really liked this video please create more videos on mining GPUs and how to modify GPUs
Thanks for the video and sharing. My DPS 480EB A worked fine after jumpering pin 1 and 4 (pin 31 and 36 as marked on the PCB). Very quiet fan by the way...
If you are worried about shorting to case, either add a grommet or use a non-metal screwdriver. They exist for this very purpose.
done it to mine, exact model worked flawless thanks for the guide, i too found the same info online and it was wrong. Thank you for correcting that and showing us
I have a question, when you plug the device into the outlet, does the fan turn on immediately, or only when you connect the resistor. Because mine turns on immediately, and when I insert the resistor, 12 volts appears on the terminals and the fan turns on at a much higher speed. Also my power supply doesn't need the whole transistor thing, the soldered resistor works and it's the exact same model
I have this exact same model, works with only a direct short to pins. powers on instantly...
Nice video on modifying the power supply. I am a bit confused about the concept of BitCoin mining. It was my understanding, that the cost of electricity outweighed the benefit of doing so.
when i did my power supply, i just adjusted the internal regulator , after breaking the over voltage pin on the circuit, but soldering it i ended up cutting my soldering iron tip to a flathead like shape , Then as i was heating the plate up i noticed the soldering wouldnt stick , i had to sit there and heat it up generously in one spot until i got a part of the soldering to stick, then SLOWLY work my way down the line , Also dont touch near the edges, last thing you need is a soldering short, i had to heat mine up , and scrape it with a razorknife.
thanks for this. helped me out quite a bit
Excellent video and spot on. Tried it out on a HSTNS-PL11 1200w version and it works fine using the components listed.
For a second iteration used pin 30 for the capacitor ground, which is the 12v sb return.
Interestingly pin 32 is the SCL @5volts which powers the base of the TIP41.
The time delay is caused by the capacitor charging up through the resistor and then hitting the voltage threshold to trigger the TIP41.
Next is putting on a very board with a switch.
the first potetiometer can be a voltage regulator if it changes frequency the output can average higher voltage
Your experiment is working. Thank you!
Thanks for the validation. I figured out the voltage pot myself, but I was hoping there was an option for further adjustment
Check out this video:
ua-cam.com/video/9--g63ew9HU/v-deo.html
You can bring it up to 14.4 by adding a zener diode, I modified 5 pieces of this kind, the model with 1200W and 100A.
Woah can you explain this 😌
Muchas gracias por tu buen y meticuloso trabajo. Estoy totalmente de acuerdo con darle una segunda vida a los equipos y este es pequeño y potente. Gracias de nuevo!!
Great vid.
Q1: Can you list some model #s of (cost effective) server PS's you prefer?
Q2: Any thoughts on extending the housing to protect the components which project out the back?
(Guess RC (Radio Control) guys might have some info on making the PS portable.)
Q3: Does HP 490594-001 438203-001, aka HSTNS-PL11 use a regular
(standard) PC cord? Or is the end that connects to unit different?
EDIT
A: HSTNS-PL11 uses regular PC cord.
PS: In the USA /in a country you have to pay for electricity... How much per thousand in hardware can you make Bitcoining?
I think the first knob you turn is the fan speed adjust
Thank You very much your video very helpful!Work also with my HSTNS-PL30!!!!
what was the max voltage on this one?
use the pb18 and save the hassle of adding transistor etc.
You have video adjust current ? Thanks!
Do you happen to know how to increase the voltage beyond it’s factory limit? I’d like to get into the 14v range. Any help would be greatly appreciated
Do you have a simple circuit diagram of the auto start.
you could probably start a car with a few of these supplies in parallel and raising the voltage a bit xD
Hi, plz make video of hp model no-HSTNS-PL12, how to start and modify
I know this was quite some time ago. But, would you happen to know if this procedure will work on the HSTNS-PD18? That supply is 750W and 62A. Part # 5606822-101. Mine will be general use rather than for mining, though...
Yes it does all you need is a 12v led resistor that's what i used and works fine to power it on 👍
why not just use a breakout board?
Where can I get the information of which potentiometer from the board is for what use.
Because there are so many, and I accidentally turned a few, so any help would be appreciated
Can you help me how to remove the protection
FRIEND I HAVE 2 QUESTIONS 1- THE CONDENSER OF 100 MICROFARADIOS BUT IT DOES NOT SAY OF WHICH VOLTES AND THE SECOND THAT IS WHAT IT WANTS TO BE ACHIEVED WITH THAT MODIFICATION WHICH IS THE FUNCTION TO ADAPT THAT THOSE COMPONENTS, CLOSE TO THE PART OF THAT AUTOMATICALLY WORKS.
Hello, I have a similar PSU, only 750w, HSTNS-PL18. It works okay but the fan speed is too low and it is heating quite a bit. Any suggestion how to increase fan speed? Thanks
Hello, did you ever find an answer to speeding up the fan?
Hello thanks for your video my DPS800 12.8v power supply is fine for Gpu or is it too much
i hope you know there is something called a breakout board
# Scroll to end to see my end result that appears to be working for me.
I know this is old, but I figured I'd post here in case your still reading or if anyone else sees it.
I have the HP HSTNS-PL11 PSU, trying to just have it come on when I plug it in to use for a lipo charger for radio control use. I found a blog/site that said to use a 750ohm resistor from pin 33 to 36. That didn't work, then I found a site that said use lower resistance, so I put 2 of those in parallel. Then it seemed to work. I ran through a charge cycle pulling 30A out of it and it was fine. However, I try to use it today and the power light flickers on/off/on/off and the 12V output cuts in and out to match. Then it was suggested you could just put a switch between 33 and 36, plug the psu in, then flick the switch and it would come on. That works, but it powers off after 30 seconds. Well, the 12v output drops to 0v and the fan keeps spinning until I unplug it.
Now I'm going to try your way.
I also have a DPS-1200FB. Similar instructions for it. I have 2 of the 750ohm resistors in parallel on it and it stays up after plugging it in for about 20 minutes, then it shut off when under a 15A load.
I also bought a pre-modified pair of dells which I'm trying to replace because the fans in it sound like a 747 taking off until there's at least a 3A load on it, then they calm down. Would be fine, but I use my chargers to discharge to storage as well, since the chargers only discharge at 80w, it takes a couple hours to drain my packs down to storage. That's a long time with no load to listen to the fans in my office.
Getting frustrating.
EDIT 08/29/2020:
Running a test now with your setup, although my resistor is only 1/4 watt. Just ordered some 2W in case the 1/4 watt dies. Not sure it matters, but with mine, I can't unplug it and plug it in as quick as you or the green led blinks. I have to leave it unplugged for about a minute, then it turns back on when I plug it in.
EDIT 08/29/2020 B:
Didn't work. Seemed to work fine until I unplugged it, waited a long time, then plugged it back in. The power LED flashes and output voltage is intermittent.
EDIT 08/30/2020:
currently only using 150ohm from 33->36 and this appears to be working fine. I've charged packs off it at 15A using a revolectrix GT500 charger 3 times, discharged once, storage charged 4 times. It has stayed on the entire time without issue and now turns on/off with a power strip I have it plugged into.
Max voltage range ? 14.7 ? Battery charger psu 14.7 volt ?
ua-cam.com/video/9--g63ew9HU/v-deo.html
I tried on a HSTNS-PL18 and it blew up...
That's a different board
Did you just covered the blade with heatshrink or is that electrical tape?
What soldering iron is that? Works great
Can you turn it on to see if it works by just jumping a wire from 33 to 36?
transistor, capasitor and resistor for ?
Hello. please help me, I accidentally made contact between those small pins, the fan went into speed and from that moment even if I make contact between the first and fourth pin, I don't have 12v and the green LED doesn't light up anymore. Did I burn her? Is there any chance it will work? I have the same power supply. Thanks a lot
nice video you also have this for the HSTNS PD30?
Is there anything you can do to get this up to 14.6v? Like the resister mod they have for the DPS-800 HP PSU?
Have you try to supply input with 220 v AC from home power grid?
Hi Bicoinmining. I enjoyed your video. i just wanted to let you know that i have a HSTNS-PL28 (460W) that i will use to power a 1080TI GPU (about 260W) and i just jump the 1 and 4 pins like yours, but i didnt need the delay starter, just the jump and the PSU start right away, even if you disconnect the AC and connect it again, it starts right away.
Maybe that something that has to do with models?
Thanks.
wow this is good to know. please look at my comment above and let me know if you have any input. cheers :)
did you use a resistor? if so, what ohm? i wonder what range can be used. or , if one needs to be used at all.
Did you get it working, I wanted to put 2 in series to get an efficient 24v power supply
Same here... I have 3 DPS-1200 and I only added the 470 ohms resistor! It powers ON every time!
How many volts does a 100uF capacitor use?
Hello thank you. Did you know how to do it with the Dell GDPF3 1100W PSU?
Why so many parts to make it on? It just requires a short between 1 and 3 pin for it.
Hi friend. I did the mod, but I'm noticing a weird behavior. I turn the PSU on, the fan starts spinning, I put a load on it and up to 3A, the fan runs at the same speed initially, after 3A the fan slows down. Does yours is like that?
I know this vid is a few years old but im using this same power supply for charging lipos, is it normal for this model to be at 13v and move from 13.40v to 14v?
No utilizas un pequeño disipador para el lm317? No colapsa ante una demanda impotente de corriente? Un abrazo!!
BitcoinMining, by connecting a jumper wire from 33 to 36 my supply will power up. Would this hurt the supply to do it this way?
How did you put load on the supply while testing it?
I Tryied to get the 12 volt across just like u showed put the resistor and was only able to get 12.09 volts from pad 5 not were u showed the voltage at positive and negative spot I Tryied every combo of pins shorted never worked
Hello I have one question I cant see there 24 pin motherboard pins can you explain me how pin out it to this PSU
there is no 24 pin on this psu it is for a server
@@WhateverUDecide No 24 pin here, that's right. But it must be somehow possible to attach a 24-pin ATX connector to this power supply. Server is just another PC in a different form-factor. I have that question, too. Makes perfect sense because these server PSUs are much higher quality than the regular PC supplies that fail unpredictably. I'm actually a bit surprised people only mod it for mining (or battery charger!!). In fact, it's an excellent solution for an inexpensive server. Because server stuff prices have +00 even for a lousy bracket. So you don't wanna pay that much for a really small-scale solution. But if you want it to run 24/7, then you better use server parts.
DPS-1200FB ... did you figure out how to disable the OVP?
Wow so original Bitcoin gangster.
Друг ! Спасибо!
Any thought on how to reverse engineer a SuperMicro server PSU to do the same thing?
Any suggestions how to add an on off switch instead?
Hi Sir ! I got one of this lately , but first try is not working at all , when turn on the power measurement is good , but after loading the power keep dropping until 0 , can anyone have any idea why ? thanks
This is why I have 1 ceramic screw driver lol
What is the watts on the resistor you used?
Can you give me fan dimensions and is the fan pwm?
How does the fan communicate/get orders to slow down or spin faster?
Is it based on a load parameter or a thermal couple!?
Hello would that work on a dell power supply?
Hi i followed your video step by step, but didn't worked for me :( The psu turns on but after 10s it goes off! Have you any idea to solve this issue? Thanks
can you help me too, be quiet! platinium 1200w or hp server 1200/1500w. Which one should I choose?.the most important for me is less power consumption. I'll use 6 or 8 cards rx 570 with btc-t37.
Hello, i saw some psu like this, they dont have any resistor, capacitator or transistor... Only put a switch on 1 and 4 pin? is that ok? without elektrical componenets???
I have seen the same solution. Have you had any problems running the PSU like that? I think he installed all those components so that the PSU will start again automatically if the power goes away and comes back.
Do you know if it's possible to make this PSU deliver around or more than 13.5V?
Could you not just use a switch? Kill the switch then unplug the power supply. Then when you need to plug it in again, just plug it in and flip the switch?
cool video, but your hands are blocking the view of most things you do - would be really informative if your camera was facing the other way, 1st person or top-down
Hello, can the voltage be raised to 14 volts
could hook a little relay in the mix there powered from a 12v atx psu molex cable to act as a remote turn on. which connection do you think would be the best to break and insert the relay/switch? and in that case the delay would not be optimal? i may do that. thanks for the tut.
edit:
i wonder. if there was a power outage and you had this hooked up with in conjunction with an atx psu for gpu mining,, would the delay of the atx startup be enough of a delay to omit the transistor and capacitor. ill try and see i guess. wish there was more info on this type of thing. the knowledge is so scattered over many forums.
if anyone can recommend sites that shares this type of tinkering for mining, please leave links.
thanks
is it similar to HSTNS-pl28?
This not Work For Power Supply PS-2112-2L 1100watt Right
93% efficiency ? That's between gold and platinum !!!
Is it possible to replace the potentiometer with a resistor to get the voltage up to 13.7 volts?
HSTNS-PL18 you can
Can a variable be added and if so how?ex:13,14,15 volts??
How to speed up the fan?
Hi I have a HSTNS-PL53 yo know how turn on?
Up volt 13.8 for use hamradio
nice job man :) Where can i get a data sheet for this PS?
Why can't you just short pin 1 to 4. That is what I did, seems to power up and work no-issue? I only use it to power a lipo charger though
That works fine until you unplug the power supply and plug it back in. It will power on with just a jumper but if you leave it connected and then lose power or plug and unplug it will stay off.
Anyone figured out how to make this PSU do 14.2v for charging?
Hi great job but here a challenge to you. Can you hack a hp-dps 750ab-3 to 14.6V?
Hi, if you know that how to increase the voltage of Hp dps 750w then please tell me, Regards
hi dear, can you please help me that how can i get 14v from this model of power supply? waiting for your kind response..
AMIGO TENGO 2 PREGUNTAS 1- EL CONDENSADOR DE 100 MICROFARADIOS PERO NO DICE DE CUANTOS VOLTIOS Y LA SEGUNDA QUE ES LO QUE SE QUIERE LOGRAR CON ESA MODIFICACION CUAL ES LA FUNCION AL ADAPTARLE ESOS COMPONENTE , CLARA A PARTE DE QUE PRENDA AUTOMATICAMENTE.
100uf recommended 25V minimum 16V
why the NPN? a resistor works to turn on. Is this dependent on your particular use?
you didn't watch the video...
useful video but w.o change on voltage does this one work for GPU?
napisz jak zrobić w nim 13,8v
Tryied to get cheap way out just gonna buy a power max switcher one price get it over done
It just dosent work same way
the fans are very noisy.
I have never seen the turn on mod like this, this is unnecessary. Just put a 150-300 ohm resistor on 33 and 36. Also this is not how to adjust the voltage. You must locate the over voltage protection and add a resistor to it. I believe on the pl11 it is on the circuit board facing the metal wall meaning you must remove the whole board to get to it. This is a poor tutorial
Yup, this is the case with every video I've watched...Though, the resistor ohm rating is all over the place.
Hello. Can you help me with a specific power supply? contact mail please.
is someone in the room with you?? or is your house haunted? a couple of times I heard what sounded like a young child if you tell me no one was there then i'll give you the times i heard the voice sounds like a young girl i think. - one good example is she said WHY at 12:10 listen its actually 2 seconds later but goto 12:10 listen straight away - oh and omg listen at 14:24 girl laughing! - remember you are using electricity which may be electrifying the air! spirits use that energy to speak/manifest
