Power Supply Pi3

Former Member
Former Member over 9 years ago

Hi:

I'm getting that much closer to buying my Pi3. Never used one before. An absolute novice. My question is the power supply. The Officila Pi3 power adapter from raspberry.org says power supply sould be the official  5.1v 2.5A

MCM in the U.S. is selling one that is a 5V 2.4A. I live in the U.S.....which power supply it the correct one for me to buy? Kindly hel and Many Thanks.

    2.4 A is plenty. The recommendation is based on a lot of USB stuff drawing off the current.

    The one from MCM should be more than adequate.

    The 5.1V is to allow for a bit of loss in the cables and this will occure in situations where cheap USB wires are used. The official Adapter has a fixed cable that is excelent for the job. As clem57 has said, 2.4A covers added USB or Shields being added to the PI. If you are not doing this or using a powered USB Hub then a lower amperage adapter will still work. The cost of the official one is very good though so if you need to buy one, may as well go for the right one.

     

    The one I have (The official one in White), comes with adapters to suite most countries, the adapter itself will work for most countries based on 110V or 220/240V mains
