Raspberry Pi PSU Test
Type
Device(s) Raspberry Pi
Difficulty

"Easy" is not in the list (1. Easy, 2. Medium, 3. Hard, 4. Specialist) of allowed values for the "Repair Guide difficulty" property.


To test if a Raspberry Pi is receiving enough power, the stress package can be installed:

sudo apt update && sudo apt install stress

Let the following command run for a minute, then quit it with ctrl+C:

watch timeout 1s stress -m 4 --vm-bytes 50

Finally, check if the Pi has received enough power:

vcgencmd get_throttled

If the above command returns anything other than throttled=0x0, the Pi is not receiving enough power. This can be caused by a weak power supply, a bad cable (too long, to thin...), or a faulty Pi.
