APC rules.
If it has the capacity you need and the number of outputs for the actual number of things you must keep active (tower ,modem, router, one monitor, phone modem , phone, etc) you're exactly where you need to be with.
I run two on my desk to keep my VOIP active as well as giving me time to shut down my machine.
I highly suggest all LCD's and low voltage rechargeable items such as your mouse be on the surge protection as well.
A power up from outage often kills mouse chargers and LCD screens (TV's included).
The normal surge protectors you find in homes are only good for a few months , they have a "lifetime capacity" rating , not consistent protection rating since they absorb the overage not dissipate it.
A good UPS has the ability to use excess energy to charge batteries and has a load bank to dissipate it as well.
