I'm considering purchasing a UPS to protect my setup, specifically the CyberPower LX1500GAVR, which has a rating of 1500 VA and 900 W. My primary concern is that I want to connect my desktop PC, which has a Ryzen 5 7600, an RX 9070, a few fans, SSDs, and a hard drive, all powered by an 850W 80+ Gold PSU, as well as my main 27-inch monitor. Would this unit be suitable for handling any brownouts or power flickers? My goal is to have enough time to save my work and shut everything down during a power outage. Also, I've heard that good surge protectors cut off power completely when they fail; does a UPS function similarly, or does its surge protection work differently?

I would actually advise against that model because it doesn’t use a pure sine wave output, which can be an issue for setups like yours. It's best to look for one that offers a pure sine wave, especially since your PSU has Active PFC.
I also use this UPS with a Threadripper rig that draws about 1000W at peak and it works great. The moment the battery kicks in, I've set my system to automatically reduce power consumption by 50%. This gives me around 8 to 10 minutes to safely shut things down. Plus, my system will handle the shutdown automatically within 3 minutes if I'm not around.
Absolutely! The CyberPower unit is a solid choice. It outputs a perfect sine wave which is important for your devices. In the event of a power failure, you typically have about 2 to 10 minutes to save your work and safely shut everything down, depending on how much load you're pulling from the UPS. If your area's power supply is generally stable, you might get by with just a surge protector, but having a UPS is definitely the wiser choice for work-related setups.
Good pick! The built-in AVR will manage minor surges and brownouts well, and with the capacity it has, you'll have ample time to perform a clean shutdown.
