So a consumer drive, on a 22x80mm card that barely has enough physical space for 8TB of NAND (+controller and DRAM) and doesn't come anywhere close to having enough space for the capacitors needed to provide enterprise-level full power loss protection.

The drive still shouldn't fail entirely from a power outage, and should at most suffer data loss, but at the end of the day it's designed to be cheap rather than reliable.

Lesson learned.

I needed it for an experiment where I had about 6TB of small files to process and wanted to have them on a single drive. It did the job and then I repurposed it for backup / dump drive for stuff I didn't want to delete, but also didn't now where else to put it.

The drive shows up in the system but with 0TB capacity, I recall once or twice it reported 8TB but I was unable to read anything.

I'll have a look one day maybe that was something simple like dead cap that I could replace (I have microscope, rework station).

Are you using the drive in an external USB enclosure? Those sometimes have power delivery that cannot keep up with the demands of high capacity or high performance drives.
No, it is mounted on the motherboard (Gigabyte with X570 chipset) also has a thick heatsink.
Samsung and others (including WD IIRC) do internal journaling, so even though they don't have capacitors the drive shouldn't get bricked by a power outage.
