Raspberry Pi Power Supply Check

This script is designed to assess the stability of your Raspberry Pi's power supply and cable connection.

Before running this script, make sure you have sysbench installed:

sudo apt-get install sysbench

Running the Script

wget https://raw.githubusercontent.com/senhan07/Raspberry-Pi-Power-Supply-Check/main/raspberrypi-power-supply-check.sh
sudo chmod +x raspberrypi-power-supply-check.sh
sudo ./raspberrypi-power-supply-check.sh

If you're pi is correctly powered (stable power supply and quality cable), after running the script, you should get something like:

 45.6'C 1400 / 600 MHz 1.3813V -
 55.3'C 1400 / 1400 MHz 1.3813V -
 58.0'C 1400 / 1400 MHz 1.3813V -
 60.2'C 1400 / 1400 MHz 1.3813V -
 60.2'C 1400 / 1400 MHz 1.3813V -
 61.1'C 1400 / 1400 MHz 1.3813V -
 61.1'C 1400 / 1400 MHz 1.3813V -
 60.8'C 1400 / 1400 MHz 1.3813V -

If your power supply cannot provide a stable 5V 2.5A or if the cable is insufficient, the script output may indicate throttling and under-voltage occurrences:

 39.7'C 1400 / 1400 MHz 1.3875V - Throttling has occurred, Under-voltage has occurred,
 48.3'C 1400 / 1400 MHz 1.3875V - Throttling has occurred, Under-voltage has occurred,
 52.1'C 1400 / 1400 MHz 1.3875V - Throttling has occurred, Under-voltage has occurred,
 54.8'C 1400 / 1400 MHz 1.3875V - Throttling has occurred, Under-voltage has occurred,
 55.8'C 1400 / 1400 MHz 1.3875V - Throttling has occurred, Under-voltage has occurred,
 56.4'C 1400 / 1400 MHz 1.3875V - Throttling has occurred, Under-voltage has occurred,
 57.5'C 1400 / 1400 MHz 1.3875V - Throttling has occurred, Under-voltage has occurred,
 58.0'C 1400 / 1400 MHz 1.3875V - Throttling has occurred, Under-voltage has occurred,
 59.6'C 1400 / 1400 MHz 1.3875V - Throttling has occurred, Under-voltage has occurred,

Throttle Code

Refer to the following table for code meanings:

Code	Meaning
0x80000	Soft temperature limit has occurred
0x40000	Throttling has occurred
0x20000	Arm frequency capping has occurred
0x10000	Under-voltage has occurred
0x8	Soft temperature limit active
0x4	Currently throttled
0x2	Arm frequency capped
0x1	Under-voltage detected
