CyberPower 1350VA Simulated Sine Wave UPS Battery Backup System Expired

Nice find, guess I'll go to costco and refund the difference via manager. (Purchased within a month)

Sine wave wise, as far as i know with my research for a week, PC power supplies now days can handle either Pure and Simulated without any problems.
The claims about PC PSU need Pure are majorly talking about PSU 10yrs ago without standard like modern gold plat certificate. They only situation you need Pure is the electronics with sensitive wave requirements, which are medical equipment and laser printers etc, search what electronics need pure sine wave if you needed.

Also the premium Pure battery replacement after 3 year will cost a bit more than Simulated.

I am NOT against people purchasing the higher quality Pure, I'm just here to state that simulated UPS is better bang for the buck in terms of using it as PC UPS.

Not necessarily better, but clearly different. However, since simulated sine wave occupies the entire bottom end of the market (from small power strip style units to ones like this CyberPower), there is a correlation that some buyers might make between more premium UPSes and the availability of pure sine wave. Will you find pure sine wave in a cheapo UPS? Basically never. Is a pure sine wave necessarily better than an otherwise equivalent simulated sine wave UPS? No, but typically pure sine wave models exist in a price and quality tier just above "average".


Compatibility issues with simulated sine wave are indeed far from a widespread issue, though a careful test might be recommended after giving the UPS a day or two to charge up. There are some risks to this test, but if you get 5-10 minutes of solid run-time you might expect the same in future real-world scenarios. I'll put a separate comment about my own recommendations regarding this issue.

One warning I'd add for an OLED TV is to check the peak power draw rating. I've seen OLED TVs rated for over 600W. This UPS is rated for a peak draw of 810W, and while an OLED would rarely reach peak draw often or for very long (unless you just stare at full brightness white screens all day?) you do want to ensure you have a decent overhead between your TV's potential peak draw and your UPS' peak load capacity. This is in part because you might need more than a couple of minutes to actually shut things down gracefully in the case of a power outage (and near peak load retail UPS times are indeed measured in minutes).

The specifications sheets for the two models suggest that the CP1350AVRLCD has denser batteries (9Ah vs 7Ah), giving it twice the runtime at peak load (and 50% more run time at half load). Of course, you could make this change yourself the next time you rotate those batteries out!

Good luck!

I do IT support for a number of fast food locations and we use almost exclusively CyberPower UPSs. Each location might have 8+ and they do what they're supposed to.
