Hmm that's really really surprising if thats the case. According to the spec sheet [1], its TDP is 95W. RAM itself is 3W each, the cooling fans is easily 5W, the CPU cooling fan should be another 10W-20W. Would love to learn the configuration that gives you 20W power usage total. To put into perspective, my mac M1 uses 20Wish normally for regular usage.

> its TDP is 95W So AMD and Intel measure TDP differently because obviously they do. Intel's TDP is based on the max the CPU can generate while AMD is based on what an average user would encounter.

  Intel's TDP is more based on the max the CPU would draw, when all the various Turbo modes are disabled. Which reflects approximately zero real-world deployments except for the very low-end parts where Intel disables the Turbo modes for product segmentation.

  You've got it the wrong way around there. AMD is much more conservative. https://www.extremetech.com/computing/319402-intels-desktop-tdps-no-longer-useful-to-predict-cpu-power-consumption https://www.extremetech.com/computing/319402-intels-desktop-... "It’s easy to see why Intel hasn’t changed the way it defines or communicates TDP to its customers: It would make the company’s high end look vastly worse compared with AMD. A Core i9-10850K will draw up to 265W. If you want an AMD CPU with that kind of power budget you have to buy a Threadripper."

[1] TDP is worst case sustained heat output for selecting heatsinks, not representative of typical consumption at all. Typical CPU fans are also like 12V/0.25A max with power variable between 50 to 100% or so. 20W idle is thus very believable for a build by a sane person[2]. 1: https://www.gamersnexus.net/images/media/2017/CPUs/tr-1950x/pwr/amd-tr-pwr-idle.png https://www.gamersnexus.net/images/media/2017/CPUs/tr-1950x/... 2: Personally I often end up with more substantial configurations like 12V/1.5A 80mm with couple 12V/1A as sides but my suspicion is my lack of sanity is a huge contributor to that

I run ThrottleStop on windows with everything set to minimum, so the CPU is pretty much running locked to 800mhz - absolutely enough for a NAS.

I just got a "1 Liter Form Factor" HP DeskPro 405 G6 Mini that measures about 175x175x35mm (7x7x1.4 inches). AMD Ryzen 7 4750GE PRO (Zen 2) that has a base 3.1GHz clock for eight cores (4.3GHz all boost) which is an APU with eight Radeon GPU cores, in which I DIY added in 64GB of memory, and a 1TB Samsung 980 Pro. With the Intel AX200 WiFi 6 and BT 5.0 disabled, it idles at barely 12W. Running a bunch of virtualized loads (nothing crazy) in XCP-NG, it's consistently under 20W despite no matter what's running on it. If I had it going flat out (with a 5GbE NIC plugged in via USB Type-C) under something like heavy video rendering (CPU+GPU+storage) loads it peaks at about 48-50W. We're entering an era of pretty fantastic power consumption, especially if you shy further away from Intel SKUs at the moment. The Intel SKUs are pretty frugal, but the AMD ones genuinely sip power and are only getting better.
