Raspberry Pi 3+ Power Supply (Official) (CE00278)

This is a placeholder topic for “Raspberry Pi 3+ Power Supply (Official)” comments.

The Raspberry Pi 3 Model B is the most power hungry platform released to-date and requires a 5.1V 2.5A power source. This is the official power supply by the Raspberry Pi Foundation and is suitable for use with all Raspberry Pi Models, including the latest Pi 3.

Looking for power supply for Raspberry-Pi 3B+ which run Octoprint and a Logitech C270 camera to drive FDM 3D printer. The official 2.5A wall-wart looks OK, but I like the idea of the extra wiggle-room in the R-Pi4 unit (3Ah). However, I will need a USB-C socket to micro-USB plug adapter. What options do I have?

Hi Peter,

The official power supply would be best as it is 5.1V as required by RPi SBC boards (to avoid undervoltage issues). There is plenty of elbow room for peripherals, so a webcam should be totally fine.


Thanks, James.

My workflow is based on separate power for printers and Pis. I know I could change it, but the existing workflow works well and I’d rather not change. The way I power the Pis at the moment is not adequate, and I want to replace the USB power supply.

Looks like the 2.5A units are best - at least I don’t have to buy separate USB plug converters.
