Why can my uninterruptible power source handle an entire workstation and 4 monitors for half an hour, but dies on my toaster in less than 30 seconds?

Lost power today. My toddler wanted toast during the outage so I figured I could make her some via the UPS. It made it all of 10 seconds before it was completely dead.

Edit: I turned it off immediately after we lost power so it was at about 95% capacity. This also isn’t your average workstation, it’s got a threadripper and a 4080 in it. That being said it wasn’t doing anything intensive.
It’s also a monster UPS.

Edit2: its not a TI obviously. I’ve lost my mind attempting to reason with a 2 year old about why she got no toast for hours.

Is your threadripper and 4080 are going full bore? Meaning running benchmarks, rendering video or playing games at 4k 120fps?

Because a computer when iddle is very efficient, I would say you don’t consume more than 150-200W with the displays. Your toaster is what 1000-1500 W? and when on, it consumes that much.

A resistive heating element is a huge powe hog, like what you have in your toaster.
