Cost to run a QNAP TS-464 (4-bay NAS)
A QNAP TS-464 (4-bay NAS) (NAS) draws roughly 12 W at idle and up to 38 W under load. Run 24/7 at a typical ~20 W and the US average of $0.17/kWh, it uses about 175 kWh a year and costs roughly $29.78/year ($2.48/month). In higher-priced regions such as Germany (€0.40/kWh) the same device costs about €70.08/year. Adjust the calculator for your own draw and electricity price.
