Cost to run a Supermicro Xeon D-1541 build
A Supermicro Xeon D-1541 build (Tower/custom server) draws roughly 30 W at idle and up to 80 W under load. Run 24/7 at a typical ~45 W and the US average of $0.17/kWh, it uses about 394 kWh a year and costs roughly $67.01/year ($5.58/month). In higher-priced regions such as Germany (€0.40/kWh) the same device costs about €157.68/year. Adjust the calculator for your own draw and electricity price.
