The raspberry pi boards typically draw much lower amounts between 200 and 500ma.
Raspberry pi 3 power consumption per hour.
The recommended amount is between 700ma for a raspberry pi model a and up to 2 5a for a raspberry pi 3 model b see power supply requirements in the magpi issue 56 page 39.
The newer pi 3 a is slightly lower than the b but only if the on board wi fi is disabled.
On power up of the arm cores from idle.
Here are the same results presented as a chart.
The power requirements of the raspberry pi increase as you make use of the various interfaces on the raspberry pi.
Here are the results.
Pi state power consumption.
Please also have a look at the video.
Pi power consumption results.
The recommended psu is 5 1v 2 5a which is 0 5a higher than for previous pis.
Usage depends on what you re doing with the pi.
Pi hardware raspberry pi zero minimising power consumption disabling the hdmi port make sure you can get ssh access once this is done first so you have the ability to turn it back on again should you need to.

For raspberry pi 0 3 we recommend our 2 5a micro usb supply.
Raspberry pi 3 model b consumes about 260 ma of current at 5 0 v which is about 1 3 1 4 watt when no usb devices are connected to it and it s in idle state.
The pi zero w has the lowest power consumption whereas the pi 3 b 2018 has the highest.
Raspberry pi 3 model b consumes less power than raspberry pi 3 model b.
Conserve raspberry pis power consumption.
In this tutorial you will learn super easy way to monitor power consumption of raspberry pi and its official 7 touchscreen display using usb voltage and current detection module.
For raspberry pi 4 we recommend our 3a usb c supply.
Raspberry pi 4 b.
All figures in milliamps ma.
The uni t clamp meter reads to 3 decimal places of an amp but it won t give a true picture of peak instantaneous current e g.
This matters only when selecting a psu to run your pi you already have the official recommendations of a 3 0 amp psu for that.
The gpio pins can draw 50ma safely distributed across all the pins.
The raspberry pi 3 launched this week is more powerful than the pi2.
It also requires a bit more electrical power if you re going to be hammering those four a53 cpu cores.
Measuring raspberry pi power consumption.
See this post for more information and instructions how to do all of the above.
