Choosing UPS units when buying computers

In places where power interruptions are common, a desktop computer without backup power loses unsaved work and can be damaged by sudden shutdowns and surges.

What a small UPS does

It keeps the computer and monitor running for a few minutes during an outage — long enough to save work and shut down properly — and protects against surges and short dips.

Size by load

Add up the power of the computer and monitor and choose a UPS rated comfortably above it, in both watts and VA.

Line-interactive for most offices

Line-interactive units also correct moderate voltage variations without using the battery, which suits most office environments.

Protect the network too

The router, fibre terminal and network switch should be on a UPS, otherwise laptops lose connectivity during outages even though their own batteries keep running.

Plan battery replacement

UPS batteries typically need replacing every few years. Record purchase dates and budget for replacements.

Consider central protection

For larger offices, a central UPS for network cabinets and critical desks may be more efficient than many small units.
