Achieving 11M IOPS and 66 GB/S IO on a Single ThreadRipper Workstation

Another downside is powerconsumption at rest. Supermicro board with 2x Xeon use 80watt at minimum. Add a 10Gbit switch and a few more peripherals and you’re looking at an additional $€80/month electricity bill. Year after year, that is $€10.000 in 10years.

Of course that is nothing compared to what you’d pay at Google/Azure/AWS for the AMD machine of this news item :-)

12V only PSUs like OEMs use or ATX12VO in combination with a motherboard without IPMI, similar to the German Fujitsu motherboards, have significant lower power consumption at rest. Somewhere around 8-10Watt without HDD. Much better for home use IHMO.

In the US, electricity rates are typically much cheaper than the EU. My rate is roughly .08 €/kWh, for example, and I don't get any subsidies to convert to solar, so I have no way to make it pay off for myself within 15 years (beyond the time most people expect to stay in a home here), while other states in the US subsidize so heavily or rates for electricity are so high most people have solar panels at least (see: Hawaii with among the highest costs for electricity in the US).

Regardless of electricity cost, all that electricity usage winds up with a lot of heat in a dwelling. To help offset the energy consumption in the future I plan to use a hybrid water heater that can act as a heat pump and dehumidifier and capture the excess heat as a way to reduce energy consumption for hot water.
