    Hi,
    gotta a couple of questions about a macpro, thanks very much in advance!!
    1. If I am turning it on and off 3-4 times a day, is it better to shut it down and turn it on each time or sleep it and wake it up?
    2. Ive been checking the volts variation on my ups, it has gone from 118v to 106v and up again, is this bad for the computer? whats the minimum and maximum it whould be at?

    1. It doesn't really matter, as both sleep and a total shutdown will hit the PSU with a high power draw for a very short period of time (startup currents). That said, it might be better to put it to sleep, as some of the functions can activate the computer from sleep. Updates, automatic backups, and the like. At least this way, it gets done with less manual interference. ;)

    Shut down if you'll be away for an extended period of time, such as a vacation.

    2. Fluctuations on the AC mains is normal, so no need to panic. :D The UPS also offers protection during instances of a low mains voltage condition (brown out). :) A surge suppressor doesn't. ;) Otherwise, the nominal AC conditions are listed in the manual (90 - 130 should be about right for its design limits on US mains).
