I had a UPS fail last week, but I have two of them and my servers have dual PSUs plugged into each one. I don’t really need the uptime, but I’m mostly glad I was able to finally justify my unnecessarily high power bill to myself. :)


How does a UPS cause a high power bill? Doesn't it just charge up the batteries once and basically maintain after that?


The high power bill is due to using enterprise rack mount hardware with dual PSUs, instead of consumer hardware.


"Idle" is often measured in the hundreds of watts on enterprise/DC gear.

Newer stuff is sometimes a little better about ramping down at idle, but heck, some server fans will use more power than either of my desktop computers at idle.
