  • Pls, provide some proof for those numbers. The ‘under 5W mark’ gets often claimed but i still have not seen a valid proof (a simple measurement with a wattmeter) of it other than some spec sheet.

    The overhead does not matter really. USB 5V power supplies are cheap and efficient these days, yes you need to look out for an efficient one but even one with only 50% efficiency (which is really really bad) would only add 1W to the (lower than) 2W power in idle. That would still result in lower power in idle.


  • Thanks for providing those numbers. Pretty much what i expected

    My guess is, that those 5-6W on idle that gets thrown around in so many blog posts is probably just the CPU in idle state and not the whole board with io and other stuff.

    As i said. The RPi (and other SBC) remains king for low power and low load applications like for example smart home. Especially in counties like germany with high energy prices. But honestly i am always surprised what can be run off a RPi.

    And i just looked. The price for a RPi is actually not.that bad anymore, just saw a ebay listing for 3 * 3B+ for 100€.

    For other low power usage where arm is not feasible those intel embedded based thin clients are an excellent choice.



  • Just as a rule of thumb: 1W of constant power costs is at most 25cents (40cent/kwh, which is even high for Germany).

    The cost for a year is 1W24h365=8.76kWh which are at 0.4€/kWh 3.504€.

    So with a difference of 3-4W you pay in a year between 10.5-14€ more than for the pi.

    And i often heard the claim of thin clients idling around 5-6W, but i never got proof. Most things i saw are around 10W. Can you provide a picture? I would be really interested, honestly.
