Because you've tried different PSU's my guess is that the USB-C PD connection in the miner is messed up and is not reporting the PSU capability correctly.
yes, I believe that is probably the issue, I might try to see if I can desolder the current USBC connector and solder a new one. Nothing to lose I guess.
While the connector *may* be the problem, I'd 1st look at the soldering on the PD interface chip next to it because it is alive enough to at least report the status. That chip is what does the negotiating with the PSU
and cable to determine their power capability. If negotiation fails it defaults to 5V @ 1A vs the PD3.1 ability to deliver 24-48V @ up to 5A.
