Orange Pi Win Plus supplied with 1.42Amps PSU.

(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:

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.

Dear Igor, I am so sorry for my noobism.

 

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.

 

Please see attachment for log.
