UPS power consumption
Recently I migrated my home server (a Linksys NSLU2 a.k.a. ‘Slug’) to a more powerful device (Mac Mini). The Mini has more capabilities and hence will run more services. Time to invest in a UPS that will keep the computer running when the electricity grid goes down.
Since the power consumption of my home server is a major concern to me, I’m also interested in the extra power consumption generated by the UPS.
I was able to measure the power consumption of a MGE Ellipse 750. Power was measured with a Voltcraft Energy Check 3000 and the test load was a normal PC (note: not the Mac Mini!).
The result was: the setup consumes 76 Watt without UPS and 80.5 Watt with the UPS. Note that the batteries of the UPS were fully loaded when the measurement was done.
