[QUOTE="Digerati, post: 686071, member: 59833"] I don't think you are looking at this correctly. Backup power during a full power outage is only the icing on the cake. The biggest advantage to using a "good" UPS is the AVR (automatic voltage regulation) it provides at all other times. A surge and spike protector is little more than a fancy and expensive extension cord. They do nothing (except kill power - if working properly) for [U]excessively [/U]high surges and spikes. And they do absolutely nothing at all for dips (opposite of spikes), sags (opposite of surges) or brownouts (long duration sags). Any of these anomalies can disrupt power to your computer resulting in data loss and even damage to your equipment. In terms of battery runtime, that is a function of (1) load - the demand the connected devices put on the UPS batteries and (2) the size of the UPS. As a minimum, the UPS must be large enough to support the load long enough to save any open documents, exit any running programs, "gracefully" shutdown Windows and power off the computer. So technically, 5 minutes runtime is enough. A 500VA (300W) UPS may easily be able to support your connected equipment but a 1500VA will provide longer runtimes. I note you said "[U]few[/U] monitors" but you failed to be specific about any of your hardware. Depending on monitor type and size, they can eat up some power.
