HP Series HSTNS-PD05 model: DPS-800GB PN: 379123-001 how to start the power supp

Question

How to run the PSU outside the server? The power supply, after switching on, has + 5V and + 3.3V output, while + 12V probably requires appropriate connections of leads. I have corrected TONI_2003.

Hello.
Of course, each of us has just such a model as you only partially deign to provide. I wrote the rest of the topic myself, but is it like that? Where are the pictures of the connector and sticker of this power supply?

Nameplate:

PCB designations:

The bottom side of the connector (pins 1-32):

The upper side of the connector (pins 33-64):

Pins I was able to determine:
1-12; 53-64 -> + 12V
35 -> + 5V
36-37 -> + 3.3V
13-24; 26; 38-39; 41-52 -> GND
25; 27 -> NC
There is a voltage of about 5V on pins 29 and 31, which I "pulled" to ground through 470R. However, this did not affect the operating mode of the device.

I don't know, or rather I'm not sure, what this numbering should look like (you could have described it in the photo), but it looks like you did it correctly. It's just that I have a question whether this power supply was 100% efficient before your tests? You should do a good job of studying many posts on this Link whose solutions are somewhat about the same as you want to get, and it talks about many models from Compaq and HP (that's one).

The extreme pins are described and it is clearly visible in the attached photos. I have already studied the given link at the very beginning. Unfortunately, the most similar model described is: HP Power Supply DPS-600PB / 700CB. As it has a different pinout, the method described there cannot be used. The philosophy of downloading to the mass of signals also did not work. I am not sure if the power supply is 100% functional, so I am looking for a proven control method.

This was not what I meant, but it was not about it (I must be sure to suggest something to you in two ways), so I will only question the comparison you presented, and in the meantime I will suggest a different one ...
Let him be my type Delta model: DPS-750EB A rev 04F so check for yourself. You have these other options for measuring and confirming some yes or no theses, so I'm not going to work.

On another forum, I have already found info on how to start + 12V :arrow:

"short pin 30-31 bottom with pin 34 top, and the PSU starts"
HP Series HSTNS-PD05 model: DPS-800GB PN: 379123-001 how to start the power supp

Unfortunately, so far no one has said whether using this method has been able to squeeze the declared current out of the power supply.

I have two such power supplies at my disposal and in both cases, after exceeding about 16A, the voltage drops sharply to about 6V. It's hard to believe that both are damaged in the same way, but there is some risk. I would like to add that the + 3.3V and + 5V outputs work properly at full load.
Does anyone have such a power supply and is able to test it?

The correct way to connect is to short-circuit pin 31 to 34, and pin 30 to + 12V and the power supply works then with full power. The problem is solved and the topic is closed.
