==FAQ==

Q1: Why does the message "This power supply is not capable of supplying 5A" appear on '''RPi 5'''??

</div>

[[X728]]/[[X729]] UPS shield can provide '''enough 5A''' power supply capacity;

Please set as follows:

'''Step 1''': (Required)

Open the Teminal window based on '''Raspberry Pi OS''' and execute the following command:

sudo rpi-eeprom-config -e

Add <code>PSU_MAX_CURRENT=5000</code> at the end of the file that reads like this:

[[File:X1012-setting.png|700px]]

Press '''Ctrl-O''', then enter, to write the change to the file.

Press '''Ctrl-X''' to exit nano (the editor).

'''Step 2''': (Optional, if you use USB peripherals and require higher current)

Set <code>usb_max_current_enable=1</code> in '''/boot/firmware/config.txt'''

'''Reboot''' your Raspberry Pi 5 to make the change take effect.

'''Note:''' If you are using other OS like Ubuntu, please flash '''Raspberry Pi OS''' first, and then re-flash other OS such as Ubuntu etc after completing the above settings.
