possible soft brick or hard brick (PC+)

[Keno]

I was testing the orangepi PC+ armbian build 5.20 (Armbian_5.20_Orangepipcplus_Debian_jessie_3.4.112_desktop)

when messing with it it seemed to have random reboots. I thought initially it was because it was lacking a heatsink or fan. So I added both and the issue persisted. Thinking maybe if I flashed to emmc it might resolve the issue it froze in emmc install and is effectively softbricked from what I can tell sadly.  I also tested a second OPIPC+ but was unable to get it to boot. I tested with multiple new power cables as well.

What about using different PSU?

You are correct. seems my 2A supply was dying, and outputting less amperage. changed it to a new one. The OPIPC+ I attempted to install to emmc fails to boot completely though.
