Two years ago someone offered to sell me these for $10 a pair. They were so cheap that I bought several right-away even though there were no pin-outs diagrams or instructions to get them to work. Having ruined two of them with the wrong jumpers, I just dumped the lot into the junk box for useful parts. Your excellent explanation has now helped me to get the good ones going. Thank you very much.
I pulled a similar power supply out of e-waste a couple of years ago. Thank you for the great explanation of the hack. I was starting to worry that it was broken, but after following your instructions I am successfully using it to power my welding station exhaust fan. Nice video!
fantastic video with excellent explanation of how its done. very happy with how you explained everything. well done. using your guide i was able to get a dell cs570a-s0 to work perfectly.
Brilliant! I am just getting one of these. Thank you so much for your excellent explanation of the method to use. I already ruined a good one because i didn't know what i was doing. Thanks!

Hi. Did you found what's the pin to ground to have the fan to slow down? Mine turn on ok grounding the 2 pins you showed, but on similar tutorials for other similar fans, there is a pin to ground to slow down the very noisy fan.
Well done. Very nice job. So what we need to do is do find which pins have voltage, then connect all of them to GND via 500 ohm resistors, then find out which are used to power on the PSU by removing all other pins, one by one. Finally connect them to GND and finish the job? I am just wondering if your tutorial works with other Dell PSU models. I have some C570A-S0 PSUs and I want to power them on.
You have to try to see if it will power on or not. My advice is: 1. Measure all pins resistance while the PSU is powered on ignore those that have below 1k ohms and above 10k ohms. 2. Ignore all the pins that have 0 ohm resistance relative to the ground (the metal box of the PSU) 3. Measure all the pins voltage that left over from point 1 and 2 and ignore those that does not have any voltage or have 12 volts in your case. 4. What's leftover connect with 0.5k ohms resistor to the ground If the PSU turns on then start removing one by one until you have only those need for the PSU to turn on. If not then sorry - bad luck. Be sure to check the PSU that is operational. I hope that this will help and you will turn it on.
I would like to raise the voltage of this PSU to 14v to use in a sound project I have already lost one trying to find out the correct way to increase the voltage if you can help us
It depends of the power supply you have. Usually there is a potentiometer somewhere when you open the power supply where you can adjust the voltage +/- 0.5 volts. You will most probably not be able to go all the way to 13.8 volts. To go there you will need DC-DC boost controller. There are plenty of them on aliexpress.
When you measure 12 volts, are you getting 38 amps... I am following your setup to do battery charging and it looks like your setup makes 2.92 amps.... If you look at the psu it says 2.92 and 38 amps....

I used this method for a Dell C570-SO PSU from an R710 server, and found that those two pins (B6 and D6) were used as well. Thanks for this!
Wow, that actually works!
It also works for the 717W version too.
fantastic video with excellent explanation of how its done. very happy with how you explained everything. well done. using your guide i was able to get a dell cs570a-s0 to work perfectly.
Thanks man. I got this exact model for the same purpose and with your video I got it to work.

thanks!!! I did it work an DELL D717p-50 of 717W using your method!!!!!
thank you Sir. well done. i have some different dell supplies that i cannot find the pin outs for. I look forward to trying your method. Cheers
With this way , we can apply for many other PSUs
Thx for the Help worked for my dell a870p-00
Hi. I m trying to switch on the same model like yours , can you tell me please what are the pins ? Thank you !
Sir
For DELL POWER SUPPLY
870 Watt
Which pins i should use for switching
Wondering if a 5V (3A) output would also be possible?
eu tenho o modelo A670P-00 funciona tambem? works?

No I haven’t look for that yet.
Does this powersupply has a pwm contoller chip inside ? De numbers usualy start with UC..... ever tried adjusting to 13,8volts?
it has UCC3895 inside

Hi, did you find out how to raise the voltage to 14V?
Very nice tutorial! Do you know of a way to increase the output voltage of these supplies? I would like to get up to 13.8V if possible.

Master
I tried the solution at 10:15 but my 502W power supply didn't turn on 12v :/
Hmmm this is the first time I hear that this is not working. Are you sure that the power supply is working?
@@tedonash2681 Yes, it works when plugged into my Dell r610 server.
@@theSquashSH I don't know what the reason may be. All of the people that have tested this confirm that is working
This video is amazing, bratan
It is possible to increase the voltage
In some power supplies yes. I didn't find the potentiometer on this one
hello? How many kilowatt hours?
This PSU is 500 Wh
@@tedonash2681 supports SSD
So, connect pins X Y Z to negative. Just tell us the pins. Thank you.
This is very usefull video for me
