Then why does everyone suggest a UPS? Is it just misinformation or am I misunderstanding what they are saying
View its spec numbers. Hundreds of joules. How does that hundreds of joules absorb surges that are hundreds of thousands of joules? It doesn't. But with near zero joules, the UPS manufacturer can hype Surge Protection in capital letters. Most anything can be claimed in sales brochures. Then those who would "know without first learning" hype that surge protection to friends. Near zero surge protection becomes 100% surge protection. Myth exist when people do not demand numbers with each answer. No numbers is the first indication he is probably lying.
pez said, "protects against surges, brown outs, and spikes much better than a regular surge protector". No numbers. UPS manufacturer specs do not say that. In fact the protector circuit inside a UPS is a near zero version of same found in a power strip. So why does he say the UPS is better? Why does he not know this? Most are educated by hearsay - never demand numbers. Eyes glaze over with each number. He promotes the myth. A perfect example of why that UPS myth is so popular.
He does not post numbers. A first indication of a lie.
Second, most people always see solutions mostly in terms of what they see. See that lightning rod on a building? It provides no protection. Protection is provided by the earth ground it connects to. But most only see a lightning rod - not earth ground. Then assume the lightning rod is protection. More junk science reasoning so common. So many use observation alone; fail to first learn the underlying facts. Even after taught in 2nd grade what a lightning rod does, it is amazing how many forget about the only thing that makes a lightning rod effective - earth ground. Forgotten because they do not observe it.
Your computer is not 100% protected. All electronics are at risk - including less robust items such as dimmer switches and bathroom GFCIs. How often are those destroyed by a surge? Even those appliances contain serious surge protection. Your only concern is the rare transient that occurs typically once every seven years. That may overwhelm protection in appliances. And that would pass right through a typical UPS.
How often do you have destructive transients? Neighborhood history over the past ten years is relevant. How often do you replace clock radios, smoke detectors, and the dishwasher? Myths claim surges occur hourly. Notice long lines in hardware stores to replace timer switches and door bells. All appliances contain serious protection. Your concern is a surge that might happen once every seven year. Notice – numbers provided.
