Blackouts are happening now.
Your PC is connected to a CyberPower CP1500PFCLCD UPS and the NZXT C1200 PSU is off. During a storm it went out several times before coming back. It’s possible the surge caused minor issues, but lasting damage is less likely unless you see visible signs. Wait for the storm to pass before checking.
It should work unless your UPS is broken or nonfunctional, in which case I'd be concerned.
I've experienced this several times during storms or electrical work without using a UPS. No issues or damage occurred. It seems safe to say you're good.
You seem very cautious. It's highly improbable your device was harmed by the power disruptions since you disabled the PSU and connected to a reliable UPS. The UPS is designed to supply power during outages, so you should be safe using your computer without concern.
In addition to any switch functionality, it indicates that a significant voltage surge (such as 600V or higher) could cause an arc through the switch. This situation suggests a more serious issue than just a computer malfunction. By that time, most household electrical devices would be damaged. Unless your wiring is extremely poor, a UPS typically protects the computer from further harm. Switching off the power supply can be beneficial for your peace of mind. Have a great day!
