UPS - uninterruptible power supply - when does one need an Online supply and when can one use just a Line-Interractive supply? There is such a difference in price.
I can imagine it has to do with the speed of the Switch to battery power (when there is a problem) as well as the superior quality of Constant battery power.
With a 12 core 33.3Ghz MacPro can the switch ever be fast enough?
