Why won't my CyberPower OP650 UPS turn on?
- BBrandon GardnerAug 10, 2025
If your CyberPower UPS doesn't turn on, first ensure it's connected to a working 110/120v 60Hz outlet. The on/off switch is designed to prevent damage from rapid cycling, so if you've recently turned it off, wait 10 seconds before turning it back on.
