- You guys have asked for it for a while. I filmed all of this over a year ago and struggled with putting it on YT because you are dealing with electricity and high current potential. Please please watch this video all the way through to make sure you feel comfortable doing this mod.
** I am not responsible if something happens during your modification.**
Good Luck!
*****VIDEO UPDATE*****
In the last few months I learned that you CAN use the 1200w labeled power supplies. Everything else is the same so watch this video and then watch this one: • UPDATE!! How To: Conv...
Here are the links to what I used(mostly) but you can use whatever you might already have.

It works. Thank you !
I have seen where they just isolate the front 2 points of the board from the case. Something about the rear needs it for the high voltage side at the capacitors?
really cool
Why can the supply with blue plug connector not be used? More of them available out there, was curious. Thanks. Nice video!
It can. This video was done before I figured out the solution. They don't turn on with a resistor bridging the contacts so you have to short them out instead. Then they turn on. There is an update video linked in the description of this video.
What size solder gun did you use on the larger jumper wire between the power supplies?
I didn’t use anything crazy. I’ve used a 30-40 watt Weller soldering iron from Hole Depot. The key is to tin the jumper wire and pool solder on the contacts.
So what is the deal with the 1200 W sticker model… would it work? Because I'm having trouble locating the ones with "ultraflo" sticker
The issue has been that when I soldered the resistor across the two pins, it wouldn't turn on the power supply. I have since had luck with them and just shorting the pins out with a piece of wire and it turns on.
Thanks for sharing your knowledge. What's the difference from the power supply that doesn't say "ultrafan", it's just the fan or something else different, tnks in advance.
sorry I just saw the other comments where you explain it, my mistake
Do you have to do the floating process to run them in series for 24v. Or can you just make sure they don’t touch while on?
That is what this video is all about. Converting them so they can safely run in series.
I need to be able to adjust the voltage to 13.8-14.0 volts.
Unfortunately these supplies aren’t capable of going that high.
I left a link, but you deleted it!@@JoshMoenheli
@@petefender7519 As of 2023 (I don't know exactly when), UA-cam allows links to other UA-cam videos but not to links away from UA-cam. However, the poster of the video can include offsite links in the description below the video. I've had so many comments not post because of some reference that UA-cam does not like that I now copy any comment I make to a text file so that I can try variants until I find something that will post. After I post, I refresh the screen to make sure that the post will stay posted. I have not been able to find UA-cam's rules for what it does not allow in terms of references elsewhere. Even editing a post too many times will kill it.
Here are 13.8V mods for two models of the HP DPS-1200FB server power supply: ua-cam.com/video/F0QWQntPkO4/v-deo.html
Why and what's the difference in the ultraflow and the 1200 fan if I may ask
I’ve had issues tricking them into turning on. I’ve since found that instead of using a resistor you can just short out the pads with a small piece of wire.
@@JoshMoenheli is that the only difference? I already have 2 power supplies with the blue connector?
@@htx_rc4256 I believe so. Shorting out the pins has been working.
@@JoshMoenheli when you say shorting. you mean just use the wire soldered between the pins instead of the resistor right?
@@anothersummer2782 that is correct.
Why do you say to not use the power supplies with a blue socket?
The issue has been that when I soldered the resistor across the two pins, it wouldn't turn on the power supply. I have since had luck with them and just shorting the pins out with a piece of wire and it turns on.
I have a few of these power supplies (and variants of) and with a "1200FB A" power supply you can use a 1K resistor with success. If you use a 1k resistor with a "1200FB-1 A" power supply (blue socket) it won't turn on. You need a 330 ohm resistor and your good to go.
@@rcadtechnologies1573 so I would be good with the “blue plug” model and a 330 resister? Theses are half the price of the others
@@robaxelsson530 IMO yes. The 1200FB-1 A power supplies are a great value and are slightly more efficient than their counterpart 1200-FB A. I don't know what would happen if you mix two different power supplies to get your 24V output. 🤔 I prefer using two of the same to avoid possible issues. (probably wouldn't be any but I'm OCD 😅)
where do you get a plastic screws and nuts?
Ace Hardware, Home Depot, Lowe’s, any home improvement store should have them.
@@JoshMoenheli do you know the size?
I think I mentioned it in the video but I’m pretty sure they are around 6/32.
do you know how to get one of these to 14.5v?
Without adding something external, it won't do it. the max I have ever been able to get out of any of these supplies that I have modded over the yeas is 12.3-12.5vdc.
@Josh Moen ahhh I've modded a few others and with a resistor I was able to get 16v but these ones are a little different...thanks!
