Futro-S740

That sounds wrong, efficient intel chips should be very comparable to pi's. Measurements for the futro s740 (j4105 CPU) were [0] around 2-4 W idle when properly configured [0]: https://github.com/R3NE07/Futro-S740/blob/main/power_consump...

The futro S740, popular with selfhosters in Germany, gets similar wattage for people [0]. On a slightly older CPU (J4105). I can't measure values below 10W myself, but with 2 SSDs and 8GB RAM it never goes above that value, even under full load. [0] https://github.com/R3NE07/Futro-S740/blob/main/power_consump...

Nice overview, another venue worth looking at is thin clients. Some models like the Fujitsu Futro s740 are passive cooled, draw only 3-4w idle, can encode hevc in hardware and support up to 16gb memory and a nvme drive. There is a nice overview here: https://github.com/R3NE07/Futro-S740/blob/main/README_EN.md Another very similar alternative with support for 32g memory and dual channel is the Dell wyse 5070 https://github.com/pflavio/Dell-Wyse-5070-Home-Server/wiki These can be brought used for around 60-80€ on eBay. For about 150€ you can buy new Intel n100 mini computers on Ali express with similar low idle power but vastly better top performance.

It became so popular amongst selfhoster in Germany, that the companies selling them used almost doubled the prices :D There is a github with information about the S740 [0] including power measurements [1]. It’s in German, but should be partially understandable because it’s just data.

A refurbished Fujitsu FUTRO S740 thin client, it has one SATA m.2 slot, and I replaced the Wi-Fi m.2 with an adapter for an extra NVMe. They are pretty big in Germany as small homeservers, because there are a lot of used ones around (I paid 44€ for the 8 GB version). There’s an overview [0] page for them, and a list of power measurements [1], both in German, though.

Intel J4105 (Futro S740), running off SSDs. Here are a few user measurements [0], technically in German, but it’s mostly names. Power consumption should be below a PI4 with the same SSDs according to the internet ;) But yeah, with 4 HDDs you will use a lot of power, that is to be expected, HDDs are power hungry. I’d guess they are responsible for most of the consumption. [0]: https://github.com/R3NE07/Futro-S740/blob/main/power_consump... edit: Also, your server is running AMD Opteron X3421 from 2015. That’s even older than the already old J4105. I doubt that’s currently considered the most energy efficient anywhere.
