Sorry to hear that it failed on you. Given that they (pine64 support) are talking about the 3A and 5A 12v power supplies, I take it you weren't using a stock PSU?
I'm using a solar setup, so have a adjustable DC-DC module that takes the 12 - 14.4 from the 12v battery, and outputs a steady 12v... and it has been running 24x7 on that for about 12 months now with a NVMe drive + 2 external USB3 hard drives as a NAS box + other bits and pieces... before that I was using the board on and off for about 6 months testing different bits and pieces as the OS images were being brought up.
The fact that it didn't fail within the first few hours / days of use does suggest if it were a manufacturing defect that whatever failed hung on for a while.
