sumtingwong Posted May 12, 2019 Share Posted May 12, 2019 (edited) Ordered Orange Pi Win Plus from official Orange Pi store, it came with bundled PSU. I always get different errors when latest (by post date) linux Armbian starts and sometimes it starts correctly. I read this forum carefully and found out this is shitty PSU symptoms, so I took 20 Amps ampermeter and short-circuit PSU through it for 2 seconds, display stopped counting at 1.42 Amps. It is below specs where literally 2 Amps is required! Besides this I measured voltage and current near board PSU outlet, I got max current it eats through boot process is 0.54 Amps and voltage falls max to 5.32 Volts. Seems like PSU must fit this board but I still get that low power issues. Physics laws are wrong or what?) Someone maybe can tell me voltage should not be lower than X so board will work good. X = ? My multimeter looks like this: https://i.ibb.co/h8JJ5j6/Digital-Multimeter-VC9808-with-Frequency-Capacitance-Temperature.jpg Board: Orange Pi Win Edited May 12, 2019 by sumtingwong Link to comment Share on other sites More sharing options...

sumtingwong Posted May 22, 2019 Author Share Posted May 22, 2019 Problem solved. Ordered 8A/5V PSU from Ali-Express (revealed to be 6A) and all works fine. Oh that Chinese tech people. They can forge single-plate computer but can not forge adequate PSU. Link to comment Share on other sites More sharing options...

After 2 successful boots of my board with new PSU random boot errors started occurring again. Seems like I hit that successful boots and assumed new PSU was the source of success. Wrote latest server version of Armbian to my SD card and run the armbianmonitor -U after first successful boot without errors occurred.
