The question asks if PC restarts when powered back on after being shut down during UPS operation.
The default configuration is "Always Off". I just turned the BIOS on and off.
There isn't any looping. The PC is connected to a power strip, which connects to the UPS, and the UPS is plugged into the wall socket.
Actually, I'm not sure. I'm not very familiar with computers. I don't know what normal settings look like or how to verify them.
What it describes is essentially the setup where the monitor is connected to a power strip and also to the PC via video cable and USB. The USB is used for RGB lighting, while speakers are also plugged into the same power strip and PC. A secondary monitor is included as well. However, the explanation of why the PC starts on its own isn't mentioned in the manual.

(It should be noted that your UPS is probably quite similar to other brands, differing mainly in appearance, design, and quality.)

It’s worth noting that the PC might be misunderstanding a shutdown signal as a restart request, or there could be some voltage present that mimics this behavior.
Many modern devices feature an "instant on" capability—meaning they appear off but power is ready instantly, often shown by an LED.
The main goal here is to enable quicker restarts.
The trade-off is that some energy may be wasted, which some people consider unnecessary.
Given the setup you described and the uncertainty around BIOS power settings, it makes sense that the PC interprets a shutdown as needing to restart.
This could cause it to turn on automatically when you wish it to stay off.
I don’t have a clear idea of how the PC determines it needs to restart.

What should I do?
My suggestion is to disconnect all connected devices—wall outlet, UPS, PC, and monitor.
Nothing else needed.
You can mimic power cuts by unplugging the UPS or switching off the circuit breaker for the wall outlet.
Then adjust the power settings in BIOS/Windows to ensure the PC powers down when expected and restarts as intended.
Once this is set up (and you confirm BIOS/Windows is properly configured), gradually reintroduce each component one at a time, testing shutdowns and restarts continuously.
Be cautious of any loops forming. Keep these links handy.
It may require further investigation to understand the underlying cause.
The reasoning behind it might be complex, or another person could point out an oversight in my part.
That’s not a concern.
