Yeah, those were my thoughts when I last posted here. Did you try to disconnect the power supply from the outlet and then pressing the boot button? That's a trick generally used to discharge capacitors, since it would try to start the boot and then immediately consume whatever is left on the capacitors(or inductors, those are pretty widely used for voltage regulation).

I have a GTR 7 Pro with 96 GB ram upgrade running Proxmox.  This happened to me a few times when I first go the unit and then it seemed to not reoccur after I had it connected to a UPS for several weeks.  I just unplugged it and ran into the issue - cannot get it to post and hit the power button a second time and  waited 20 minutes for the memory training - still no post.  

Going to disconnect power for 5 minutes and then try to get this thing to post.

After several hours trying to get the system to post, I finally gave up and left it unplugged overnight.  Plugged the power in and went to lunch.  The system is back online now.   

Other than this one bug, the system is super awesome.  Hope this gets a bios fix soon!

I had the power cord connected to a UPS since my last post on September 14th.  GTR7 Pro is very stable and no issues.  I can reboot anytime and the system reboots fast (no DDR5 training).  Emailing with support to see if they have a newer BIOS.

Finally got around to installing the updated BIOS from GTRP01_P5C6V15 (06/14/2023) to GTRP01_P5C6V30 (9/07/2023) provided to me via email from support.  Did not have release notes with the bios files :( so not sure if this fixes any power related issues, but will see if this reoccurs.  I now keep my GTR7 Pro plugged into an UPS, so it rarely loses power.

Running the latest Proxmox 8.1.3
