CyberPower Mini-Tower UPS PC Battery Backups

If you have a newer computer, these may not work because they provide a simulated sine wave. The same manufacturer sells a pure sine wave version for more money. I always go for the pure sine wave version.

Good call. And one little detail people seem to over look. Make sure it’s generator compliant if you run your home on a back up generator during power outages. Most of Cyber power boxes can be adjusted for power thresholds and this is very important unless you want to fry the UPS and possible that active PFC power supply in your PC. Needless to say, with it jumping back and forth will run you crazy too.
