Where are you measuring the power consumption? I've recently started measuring the wattage of all the various electronics in my collection, and I haven't found any computer that's not underpowered and draws under 25W from the wall when idle, and that's with no HDDs and minimal RAM.
Turns out I actually have power supplies that alone draw over 30W with zero load; when trying for the lowest idle power consumption I've found that the choice of power supply matters a lot,
- sandreas 1y agoI use a cheap power meter for initial testing and a tasmota plug for having a monitoring solution as well as a second measure and a possibility ro remote hard reset in case of a freeze or something. Turns out that power supply and motherboard are the most important to save power - besides low C-states (powertop). I had best results with Fujitsu D3x17 / d3644 and Gigabyte C246 wu2. Today these are unicorns not worth hunting for. Like I said: No modern server grade board is that good while being cheap. You could take a look at Kontron K3851-R ATX If i remember correctly. Kontron bought Fujitsus Mainboard segment a while ago.
