Measure home server power before chasing upgrades
An old tower server, a NAS with six drives, a small switch, and a few can quietly raise the power bill when they run all day. After the bill rose noticeably over several months, each device was measured with s that track energy use. The old Dell tower used about 120 watts while idle, even though it was not doing anything .
The NAS was not extreme by itself, but the always-spinning drives added more than expected. Lighter were moved to a used Beelink mini PC, and the NAS drives were set to spin down on a schedule. The estimated savings came to about 18 to 22 dollars per month, depending on the month.
That is not life-changing, but over a year it becomes real money for more useful gear. A UPS with could also track longer-term power trends for a whole rack.
