Repurpose HPE HSTNS-PL41-1 PSU

[johnysmrz]

Hello,
i recently got (for free) bunch of HP HSTNS-PL41-1 server PSU and i would like to repurpose them for a high current lab power source since they can deliver 66A.
The main problem is i am unable to find any pinout description so i tried logical thing which was to connect shortest pins (PSU should start after other pins are connected) and PSU seems to turn on and voltage apperas on two big pins but it is only 6.6V which is not correct. I even tried to put some load on output (1k resistor) but still 6.6V.

Is there any other thing that i should try before full disassamble?

There is a general method to determine which pin to enable the PS to startup in the following thread. Worth a try, good luck.

check rc group forums, they uses server psus as battery chargers


EDIt   try this ??  with ggogle translate

You are my savior! I can confirm that connecting all 3 left most pins will start PSU fully and i am getting 12V on main pins

A lot of crypto miners use this style of HP server psu. There are tons of breakout boards for pcie power: https://www.ebay.com/itm/403634041698

You might be able to use these or reverse engineer and get the right connectors to design your own boards.

Need info how to increase voltage on these supplys

[coromonadalix]

ask on RCgroup ... better chances there
