My quarter rack Home lab in my basement is pulling 133 Watts right now with a low power 1U Supermicro SOC, an older Supermicro mini tower used as a NAS, and my networking gear and Internet modems. I don't have any intense workloads running at home. I was really power conscious when buying my two home servers as I know it is very easy to buy a beefy server off of Ebay that sounds like a jet engine 24/7 and pay out the nose on my home power bill.
