(3:20) Always solder one end, then cut to length. You'll be at the exact length when you cut it, and you'll have more to hold when you're making the first connection.

(6:30) you'll find that easier if you heat the pad then touch the solder to it. and it's not sodder it's soLder

(12:30) No ... just No... that is a cold solder. To properly solder, you heat the component and add the solder thread to it. You need a much bigger soldering tip to properly work with that size of component. Please don't encourage people to solder the wrong way, you're encouraging dangerous connections and putting people at risk of electric shock. PLEASE STOP Learn how to do it correctly before you endanger other people by teaching them the wrong way.

[@gustavinus]

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

[@halleffect1]

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.

[@chksix]

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.

[@blue03r6]

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.

[@RoamMeYo]

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.

[@kevinsajadi2879]

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

[@dimitrijekrstic7567]

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.

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.

[@darumaprb8500]

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 ,...

[@RoadRunnerMeep]

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

[@mrteausaable]

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?

[@gustavinus]

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...

[@jstump1972]

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

[@malteser0212]

(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.

[@billysgeo]

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

[@kyocreations7938]

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

[@roystervi]

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.

[@ptidom29fr]

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.

[@Siktah]

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

[@ronsafranic5177]

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.

[@markecklund3125]

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

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

[@criptobits282]

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

[@mikebutlermedia4211]

[@CareLESSmAyhem]

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?

[@SimRacer101]

You can, but there is a very specific process to do it correctly. I recommend reading the RC Group listed above and they detail the process for wiring it.

[@OtherDalfite]

A good video I've found on this topic is here kzbin.info/www/bejne/l32bnZaAa56gock. Not sure if it is this exact video but his series covers the topic of floating the ground of the cases of the PSUs. Theres a lot of science behind how this works but its pretty easy to accomplish in reality, just be really careful as you may have to go near some big capacitors.

[@CareLESSmAyhem]

OtherDalfite, Thanks but turns out that this power supply doesn't require you to do that to wire up in series. It literally just as simple as wiring it up on a 2s config to get double the power.

[@danman7665]

@@CareLESSmAyhem Just watch out if you do. If any of the two supplys gets deffective the casing might transfere 210Volts. Make sure you disconnect the DC grd on one of the supplys if you put them in series.

[@ApexTalk1]

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

[@leehudson1384]

Is that power supply particularly noisy when under load?

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

[@SimRacer101]

What is the model number on the power supply?

[@jasontucker4821]

The model number is the same. It is a DPS-800GB-5. It also says it is a Rev. S2F. I'm not sure if maybe the revision number makes a difference or not.

[@jstump1972]

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

[@Snipes287]

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?

[@Phillips942]

I purchased a second one and had no luck AGAIN so I purchased a different model that i knew would work. DPS-750RB-A works like a charm with my iCharger

[@robertdrinkall8947]

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

[@gustavinus]

But only 1000W when running in 220-240V I think. 110-127V is 850W and 100V is 800W. That is what is written in the label. Here in Brazil we have both 127V and 220V pretty much everywhere, but here in my region we use more 127V (220V only in some places). So mine will run in 127V / 850W.

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

[@mikebutlermedia4211]

In series would not give more amps, it would give twice the voltage. In parallel would be the way to get more amps.

[@SimRacer101]

I haven’t yet. I haven’t had any need for the higher voltage. Mike is right, in series will make it 24 volts. The bigger chargers require higher voltage to charge the bigger battery packs like the 8S packs Heli guys use. But but for drone chargers there really isn’t a need.
