Raspberry Pi Power Consumption Comparison

I use the powerjive usb power meter for older pis with micro usb power inputs or the satechi usb c power meter for the pi 4 and newer to measure power consumption with the dramble and individual raspberry pis in all cases with nothing plugged into usb unless otherwise noted.

Raspberry pi power consumption comparison.

Raspberry pi 3a the raspberry pi 3 model a is the latest product in the raspberry pi a format weighing in at just 29g and boasting the same specs as a raspberry pi 3b. On november 26 the raspberry pi foundation announced the raspberry pi zero a 5 usd computer that shares the same architecture as the original raspberry pi and a b models with a slightly faster processor clock 1 ghz 512 mb of ram and sans many of. Where as raspberry pi 3 needs a 5 5v power supply to maintain stable 5v rails during cpuburn a53 aml s905x cc will work without issue even with 4 1v power supply. I will be adding power consumption statistics to this page as time goes on.

Raspberry pi 4 b version with 8gb memory and layout of power supply components updated. Power the two systems have very different power requirements. We cut the power consumption of our boards in half as compared to the raspberry pi 3. Same as raspberry pi zero w with header already soldered.

The raspberry pi zero uses about the same amount of power as the a and at least 50 less power than any other pi b 2 b 3 b. For starters the raspberry pi 3 model b board uses 1 5 watts when idle and up to 6 7 watts when a monitor.
