In case your only security is aged surge protectors with fried MOVs, you may not have any security.

The computer component failures Do not audio like a normal surge trouble, as I described previously, but your whole circumstance is unusual, so It is really difficult to rule just about anything out.
Your eyes aren't deceiving you: the on-battery AC output from this individual UPS is cleaner than my wall energy! This UPS will run any electronic system inside of its load boundaries, simply because its on-battery output is as near to ideal wall electric power as tends to make no realistic variation.
The CyberPower CP900AVR is the greatest UPS for those who wish to back up several small electronics—for instance a modem, router, Personal computer, external harddrive, or recreation server—for the duration of a blackout Long lasting as much as 4 hours.
Taking a look at our gaming Laptop Create, these components merged ought to in no way take in over 250W. Having an 80+ Gold Performance PSU, which is about 300W of most electric power use. This leaves around 120W of electrical power free of charge for peripherals and also a watch, which can be a
This is essentially the actual-world version in the idealized waveform proven in fixer1234's response. The answer to my concern higher than, then, is "Indeed, they genuinely do make UPSes with output high-quality that bad."
I’m a senior staff members author at Wirecutter masking batteries, chargers, and charging technological know-how. I’ve been a science journalist for more than ten years, covering lots of subjects from particle physics to satellite remote sensing.
