I have a number of workstations in one location, do I need to buy multiple UPS’s?
In most cases, it is more cost efficient to simply buy one, larger UPS to back up your critical load (see FAQ answer #11). As UPS systems get larger, the per kVA purchase and maintenance costs go down significantly.

Additionally, larger “data center” systems will typically provide a higher level of protection against power anomalies, as well as support more sophisticated monitoring capabilities.
