I recently acquired one of these workstations that I'm trying to get up and running. Here are the symptoms in case anyone has ideas, but I currently have it narrowed down to either the Power Supply, or the board.
# Turns on when you connect power. You do not need to press the power button. It just turns on.
# CPU, GPU, and PSU fans all spin. PSU will start to spin aggressively if left on for a while. (I don't remember if the memory fans spin; I took that assembly out so I could see).
# No video output. Can't try onboard graphics because it has a Xeon CPU. So no iGPU.
# No beep codes, blink codes, or other errors.
I would specifically like to know if the PSU is at fault (it's my current theory). Problem being. it's a proprietary power supply.
So. How do I test it? I am probably going to take the housing off and just look. But NOT TOUCH anything because I don't have a death wish. But I'm invested. And this is taking up residence in my brain.
PSU in Question. Specs/model number and weirdo connectors.

I'll probably cave and buy a new one, but I would rather be sure before I invest $$.
Stuff I have already tried. In case someone has other ideas that aren't Power Supply.
* Parsing down to minimum config (Only CPU, one stick of RAM)
* BIOS recovery
* Installing a known good GPU
* Remounting the CPU
* Swapping RAM sticks around (It has 8 slots. 3 were populated. I verified they were in the correct layout and tried various sticks in the Number 1 slot.

***UPDATE 04.20.2024*** - Somehow this thread keeps finding people and I have still not fixed this or found a definitive answer to my question, but hopefully these voltages will help someone, or at least contribute to this discussion.

***UPDATE 04.20.2024*** - Somehow this thread keeps finding people and I have still not fixed this or found a definitive answer to my question, but hopefully these voltages will help someone, or at least contribute to this discussion. I should add, I do not believe these voltages are correct.
Measured voltages on my connector when both connectors are attached to the board and power on is attempted.
[image|3293254]
Colors are constent with typical markings
* Orange = 3.3V
* Red = 5V
* Yellow = 12V
* Black = Ground or Voltage measured
* Purple = 1V (I am not convinced this is normal, but nevertheless have nothing specific to compare to).
Even though my device powers on almost immediately after the PSU is connected to power, I can power off. Voltages with the power off.

Anything not marked has no voltage and all previously 12V lines have very nominal voltage (~.08V).
I am again starting to think the PSU is to blame. I have checked the board pretty thoroughly previously for shorts, but since it is a rather large board, this is somewhat difficult.
