The UPS Units I Tested

The [CyberPower CP1500PFCLCD Pure Sine Wave UPS](https://www.amazon.com/s?k=CyberPower+CP1500PFCLCD+Pure Sine+Wave+UPS&tag=thetestedhub-20) was my top pick because the pure sine output ran my active PFC PC for fifteen minutes and the LCD showed exactly what was happening.

The UPS Units I Tested

I compared five UPS units in my home office and home server rack across a stormy month to find which ones cut over cleanly and last.

Quick answers

How long should a UPS run my PC during a power cut?

Most home UPS units give five to ten minutes at typical desktop load. That is plenty to save work and shut down cleanly. For longer runtime you need a bigger unit.

Pure sine wave or simulated sine wave?

Pure sine is required for active PFC power supplies common in modern PCs. Simulated sine works for older builds but can cause buzzing and shutdowns on PFC units.
