I use a 270 or 330 ohm, 1/4W, 5% and all have turned on so that concurs with Oz's findings.

Looking at the guts to the DPS-1200FB (here https://github.com/raplin/DPS-1200FB) vs the DPS-1200FB-1, they are quite a bit different inside. (sorry for the blurry picture)

The Watt display on the Breakout board doesn't show anything;
The LED on the brekaout board blink green,red,bleu......
The fan on the PSU turn a little bit
The GPU connected to it doesn't turn on ;(

I have tried 3 different PSU with 2 different breakout board = same result.

Thank you in advance for your help
Look for the turn on resistor (its connecting pins 36 and 33), measure it, if its above ~500Ω, I would lower it or short it. Post a good res picture of that part of the breakout board, good luck.

I followed the following threads :

Any help will be much appreciated.

Thanks in advance,

I am just getting into using these for lipo charging.
Is this particular Power supply being discussed here a better and more reliable PSU than the HP HSTNS-PL12 750W ??
