The UPS emits a short beep during startup for one computer while it does not for another.

it didn’t turn on and the UPS:
a Forza SL-1011UL-D of 600W
connected to continuously beeping until i turned it off, then back on, and finally the PC started without pressing the power button. This situation might indicate an issue and should raise concerns.
In the past, similar problems have happened where the UPS would briefly beep before resuming normal operation.
I also have a second PC using the same UPS, but it doesn’t experience these issues, and it’s older with no GPU. Should this be a cause for worry?
When a PSU is left unplugged for some time, the primary capacitors need a big surge of current to start up. This, together with the real workload, might push the UPS beyond its 1000VA/600w limits and cause overload alerts. The UPS might still function adequately if it has been connected for a while, though occasional beeps may appear. Be cautious if power interrupts during GPU use, as the system could shut down quickly.
Could you clarify if you're asking about safety assumptions for a 1000W UPS or something else?
Certainly, with sufficient UPS capacity it can manage even the substantial inrush current from large transformer-driven lighting or electric motors. I connected a 685-watt laser printer and my home furnace—electric motors drawing up to two and a half times their rated current during startup against a load like the fan attached—to a 3000VA/2250W UPS, and it functions properly.
