A paste flux on those pads before soldering helps so much. That thing changed my life. LOL Makes it so much easier.

Hi, thanks for loading this up. my friend gave me an HP 800W months ago but I was too lazy to read RCG to figure out the wiring. your instructions were clear and I was able to solder directly on the pins and get it going in no time. hooked up to a 400W lipo charger and works perfect.

Thanks for the inspiration. Works like a charm, but I realize it could crap out at any moment. I soldered 3 charging leads directly to the tabs. Running three chargers simultaneously at full capacity and it didn't miss a beat. Two 80 watt 10 amp chargers and one 100 watt 10 amp per channel dual charger. I couldn't be happier with it.

you should just drill a small hole through that #2 terminal then use a small metal wire through the hole as if it's a diode or resistor lead though the board. will be a cleaner job. do the same thing with the big connectors. drill through the board and use the nuts to hold it on. no need to solder. or you can solder it way easier.

Awesome vid, I made this to supply 42A to my Peltier cooler and it didn’t drop below 12.3V👌🏼

It probably has gold plated on the terminals both on the ps & the barrel connectors, and also leaving it threaded 'actually' give more contact than grinding it off to a flat lesser surface area. it is the solder that is creating creating the electrical bondage between the both terminals, so more the corrugation the more the surface area.

I was headed in that direction as well. Just thought I could complicate things a little.... It's how I roll!!!

(i plan on doing this soon, therefore i watch your old video) I guess i will connect thick cables on the contacts an then connect the cable to the desired contacts. and i recommend this too, because soldering wire is always easier than full copper connections.

Can you please show the assambling and the insulation from negative ground for an 24V series mod.? Best regards from germany!

Great video! Im looking to see if I can use these in my workshop for car audio testing.

Server class power supplies are great for powering circuits. They're designed for huge power draw

Hi There is some videos in youtube showing dell or hp psu hot plugs convert to bench power suply. They could run the psu hot plugs by connecting some pins but they just could run them to take a small curent not the maximum curent. Could you please tell me how to run my "hp 2450w hstns-pr16 platinum hot plug" and "hp 2650w hstns-pr42 platinum hot plug" into a bench power suply to take the maximum curent and power? Kind regards Kevin

You need to add a micro butane torch to your soldering equipment for when you need to solder something that soaks a lot of heat! A large Weller gun style soldering gun will also work.

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 ,...

get a couple of inches of microbore copper pipe, hammer it flat to make a buss bar, bend it 90’, solder one end to the edge connector, drill a hole in the other end and screw the banana jacks on

I too have a pile of these. Please make the 24v

You need to grind down part of threads and solder after contacts touch flush.

Anyone knows what type is that flat screwdrive they use that solder don't fix to it?

I use my soldering station for most things but this is a perfect job for a 300 watt weller soldering gun.

Metal to metal contact will be accommodated by the solder. You are confusing it mechanical/structural integrity

I have the dps 750ab and this not working on that one, any ideas?

I don't speak English and I'm following your video only by the images, can you please tell me what the purpose of the blue thread is?

Using this PSU nested inside an HP Z800 power supply case. The power supply for those workstations cost a lot and sucks a lot. So, just re-routed all cabling from the old PSU case to the new PSU. The power supply for the HP Z800 is like a drawer that snaps into place with 3 connectors. So basically making the "DPS-800GB A" feed those 3 connectors. Was quite the pain to join all those cables, but next time I have only some 9 cables to re-solder into the new PSU. And the new PSU is A LOT better and cost 1/3 of the price of the HP Z800 PSU. Would be nice to have a plastic "connector" for this PSU. I wonder if it is possible to print one and add copper contacts...

The "metal to metal contact" that you are talking about at around 9:25 is wrong because the solder is what's making the contact. What you should actually be worried about is the mechanical strength of that connection, because you are going to be plugging things in and out, and solder is not that strong. Edit: you need nowhere near the pressure and time that you used when tinning the banana connector, what you needed there was flux. When done right, solder flows easily and quickly, and by done right I mean bigger flat tips for the soldering iron, and clean surfaces to solder, and that's achieved by using the flux that I already mentioned.

How can your Amp meter get the Amp reading using the clamp? The clamp is for the AC current only. To measure DC current you need to connect in series using the probe. I am puzzle how you measure it?

Could you just drill the posts through the pads to take advantage of contacts on both sides?

I got 2 "DSP-800GB A" I jumper the the 2 2nd pin to verify the fan comes on and it did. However, without the 2 2nd pin jumped I forgot to unplug it and it was plug in over night, the next day it was hot as hell. as it does not have 12v while the 2 2nd pin is jumper, it seem as if the transformer still hums and heat up. can anyone verify this or do I have a bad PSU. thanks in advance.

best recommend power supply for car amp true rated power output

You should try using flux. It flows better!

Good job, FYI : That's one of the 1000W ones. HP supply them in three wattages =800/850/1000 w.

Hello show us the 24V version please thanks

Very helpful please make video server power supply repair

Banana plug link is dead. I have 4 1200 watt server power supplies im building one big one.

Hello, I made the same. But I have a problem with the PSU 0-12V, there some shortcurt or something else, an electric arc beween the negative and the +5v pin.

Id love to see a 24V version! Of all the PS builds ive seen it seems these specific PS are by far the easiest to convert. Are the fans thermal controlled or full speed all the time?

Hello, I have atsn 7001044 but I could not run it. I looked at all the videos and documents on the internet. It works when you plug the device into the server. Could you help?

Or... you can do a Ebay search for "DPS-800GBA Power Supply Adapter board RC, HAM Radio" for a plug an play solution. I think they cost about $17.00

Is it possible to get just an edge connector to fit the card, and save all that soldering?

Ive done the initial 2 wires on mine no green light or power

I also just snagged a couple of these. Yoink. Can these be turned on by a momentary switch like a regular desktop psu.

My most powerful iron (300W) is my cheapest. My expensive ones are high precision, not high power

Hi. My dps-800gb had the fan blocked for literally 0.5 seconds. It shut down. And the green led doesn't comes on anymore. What can I do? Is there a way to reset them? I have 2 of them in in series. So 24v It surely wasn't overheating. Only hat my charger on it with no load.

This soldering tool... That looks suspiciously like a flat head screwdriver that is hardened steel... *facepalm*

hi friend, I use this psu to power a 3d printer. The 5v output is used to power a raspberry with octoprint. Can I ask you if it is normal for this standby psu to heat up? Only when I activate the psu to get the 12v then the psu cools with its fans. In standby the fans are off and then the psu heats up

would 441830-001 - HP 1200W Power Supply for Proliant DL580 G5 be the same process im asking because when i plug it in it does power up so wondering if i still need to run all the cables thanks

Thank you

Where would you suggest a switch to turn this on and off?

gracias.

Can you guide people how to turn Server PSU to Desktop PSU 24 pin to use for m-atx or itx motherboard?

Did you do anything to isolate the case in any way from mains voltage?

can i do the same thing with this power supply HP 578322-B21 579229-001 570451-001 1200WPower Supply DPS-1200FB-1 A?

I messed up with my soldering, is there another way to jump it and turn this PSU online?

This can be done with any PC power supply. ...and you can get 24v out of a bog-standard PC power supply too.

Hi I like your tool to press that solder will not stick onto can you please let me know whare I can get one thanks . PS great charger set up now I am going to your other video.

I have a similar power supply how do I find out if the Convertion is the same? I think it’s a super micro

Is that power supply particularly noisy when under load?

I got same issue as Mike Philips below. I got 3 psu, 1 is working, others works few minutes ok then shutdown after few minutes (the voltage is fluctuating between 2 to 7V) i don't understand why is it happening ? Can't find anything on RC forum why this problem occur

I have a control board that works and voltage adjust mod on the same board. has anybody figured out how to make them master and slave so you can use one voltage reference for adjustable voltage when using multiple power supplies?

How could you wire this up in series? Is it as simple as wiring it up in a 2s configuration? or do you need to release a safety mechanism?

Drill thru the PCB and mount the plugs thru hole style. Also use some 12Ga to tie them to the output lugs close to the blades. lots of different ways to skin that cat.

Using your configuration the PSU comes on when plugged in however it shuts down after a minute or so. Do you have any idea why? It is a brand new PSU, the same p/n 3791230=-001.

Hello and thank you for posting this video. II doubt I'm speaking for myself when I say that I am a visual person. Following steps in a blog is a lot more difficult than pausing a video. I do have a problem I hope you can help me with. I have the exact same psu that I am working on. Only differences are that mine is a Fujitsu brand and has one large fan on the end instead of 2 smaller ones. My problem is when wired up the way you demonstrate I only get 5v output and my light, although is green, flashes instead of constantly on. It acts as though the psu is happy, it's just missing a little something. Any help would be greatly appreciated! Thanks again

Muito obrigado!!! Tank you!!!

i'm from brazil. thank you very much.

did you ever made a 24v video?

Just ordered a pair of hp dps-750rb PSU units fro EBay and it was like $20 total!!! Can't wait to try your mod on mine!! Thanks for the useful vid. Quick question... Is a resistor necessary, or just that short jumper wire??

Thank you =)

very good video, can you do a vid of linking 4 or 6 of them together : )

Perfecto lo q necesitaba de mi fuente HP1000Watt .

Nice tutorial! I maybe want to do this too but the link for the power supply is broken.

you should have removed the thread on the plugs, it would be a much better mechanic conection

I have an iCharger 4010 Duo; would this work for my charger? As a side note, I finally got my Lizard95! Unfortunately it totally pooped out on me in the middle of setting it up. :( Hopefully BG will send me a new one. GREAT video as always and keep up the awesome videos!

Have you tried 2 or more in series to get more amps?

The issue with this is that it's 12v you need 24 volt

lol, I have been using my old xbox 360 power supply for my lipo charger, same idea reusing old or everyday power supplys

Saludos, una pregunta alguien sabe para que es el cable largo azul ?

Hi, I had done the same with my power supply, but it does not provide 12 volts, only 3.3v and 5v are coming and 12v are not available. Is there any fuse or anything which is inactive and interrupted 12 volts??? Fan is working and green light is off.. Please help me.. Thanks in advance

thanks for info - your soldering skills need much improvement

charging a battery at 6 amps ?! do you want to burn down your lab?

I'm surprised there's no comments about how ridiculously dangerous this is. It's good that you covered the exposed leads at the end but the ones being sold at the link in the description seem like they have giant exposed leads. 800W at 12V is more than enough to kill you. You should at least include a warning in your video, soldering those small wires is to work around a safety feature that is supposed to keep the 12V rail low while it's not plugged into the server.

12v is not sufficient to charge a battery. Ooopsss.😊😊😊

Pretty Quiet

В натуре,что ли????

the story is useful, but watching you soldering wires to power supply was sincerely painful !
