      @zupi said in Under voltage on the Pi3:

      According to this...
      https://shop.pimoroni.com/products/raspberry-pi-universal-power-supply

      White should be 2.0 amp and black should be 2.5 amp.

      Blast! I have the white one! Need to make another purchase :(

        I am not sure if this needed. I have the white as well, resellers put them as compatible to flush stocks I guess, and don't have any warnings unless I connect a usb powered 2.5 inch external hard, and only for a second.
        I usually have 1 usb wireless keyboard and 1 or 2 usb sticks without problem. Definitely in dark about your situation. :/

          @zupi Thanks for the info. Looking at The Pi Hut it does list my power unit as 2.5v. Will have a play with Wifi and Bluetooth settings. Have a feeling my Wireless keyboard dongle could be the cause but would struggle to replace it as it does a good job.

              Well, this is my final solution. I am enclosing my Pi in a Gamecube console and am using the original Gamecube power supply which is rated at 12v 3.2 amps. I am lowering the voltage with an adjustable voltage regulator and set the output voltage to 5.25v, so far so good.

                Power supply is very important. The current 2,5A is not only one parameter you need to guarantee. You need also this two parameters:

                • linear adjustment +/-2%,
                • load regulation +/- 5%,
                  Unfortunately I had to research this detailed information because it wasn't attached to my raspberry pi 3.
