Possible loss of electrical power
Due to possible power outage during the storm 2 weeks ago, I needed to make sure my CPAP therapy machine did not shutdown.

quality UPS for a good price. Perfect way to protect expensive home electronics like a desktop PC.
I bought this UPS after troubleshooting intermittent WHEA hardware errors on a high-end PC. After ruling out the CPU, GPU, RAM, and PSU, the issue was traced back to a failing surge protector that was feeding unstable/dirty voltage to the system.
I chose the APC Back-UPS 450VA because it offers more than just a joule rating:
Proper surge protection

silent by default
Power went out recently. Unit did not make the audible "beep" by default like they typically do which I actually prefer.

So far so good
I needed reliable surger protection for my computer. We have electrical power interuptions in our area so I believe that the protection offered by this device will do the job.

Works as needed
I bought this quite a while ago. I work at home and the power going out or flickering (occasionally)immediately kicks me off the WiFi. Usually my laptop battery doesn’t cut out right away. So I have my WiFi router plugged into this battery backup.It has been a blessing. If the power goes out and comes back on quickly I don’t get kicked off the WiFi. If it goes off and s...

What I expected
These backup are pretty good. I always buy the cheapest one because if I lose power I only need enough time to shut down the computer the right way. The only problem with these units is that when they get older the batterys don't work. I had a power outage and of all the UPS's I have only 1 beeped at me and this was the one I just bought. I have a battery store near me...
