This UPS's 1500VA (about 700 watt max output) is powerful enough to protect a computer, its monitors, and a switch or router from power surges and fluctuations.
A UPS can increase the longevity of sensitive equipment, especially a computer or DVR with a hard drive.
In our experience, hard drive failures are less likely to occur when inside devices protected by a good UPS, because hard drives need clean power to operate well.
So, if you run a fileserver, DVR, or computer vital to your business, we recommend protecting it with a good UPS.
