To what extent does a UPS *protect* the hardware?
Maintaining up-time during brief brown-outs is one thing I expect of a
UPS,
Orderly shutdown is another thing I expect of a UPS.
*protection* of the PC from irregularity in the AC Mains by a UPS,
however, I question.
Rather, it seems, any power irregularity that would kill a PC by
propagating through the PSU will also propagate through the UPS.
NO UPS MADE TODAY (according to my reading of the stats on
advertisements) eats lightning strikes and asks for more.
So per your experiences and greater technical savvy: What PSU/PC kill
power irregularities will be stopped by which UPS?
