 RC>>> Your off the store shelf UPS isnt a substitute for
 RC>>> lack of power, it allows you to gracefully shut the
 RC>>> system down and thats it. It also helps during
 RC>>> power fluctuations and such..

 SH>> Actually, when properly installed it allows for
 SH>> several minutes of runtime.

 RC> So you assume that _ALL_ power failures will never
 RC> exceed the duration of your UPS's rated runtime?

not to mention that those li'l backups office units aren't rated for much more 
than several minutes...

FWIW: i've an APC 1000VA unit here that's feeding five (5) machines... all with 
monitors, speakers, etc... by itself, it gives about 10 to 15 minutes of power 
when commercial power disappears... however, this unit has been "slightly" 
modified and has several additional batteries attached to in on the outside... 
the unit has been tested to several hours without commercial power... only 
needs more batteries to provide longer uptime... just have to watch the 
charging... some of the batteries are removed from time to time for cycling and 
refreshing...
