Does a Line interactive UPS work if you exceed the maximum power draw while being powered by the wall?

Most designs will have an overload condition of roughly 125% for a few seconds. Line interactive means that there is a fraction of a second before it switches to battery power. There are some units when it drains the batteries, would shut off and won't turn on when AC comes back. It means you have to change the batteries beefier it works again.

I would typically recommend an online it double conversion type.

I can tell you that I have issues when I plug a laser printer into mine and try to print.

I am thinking of getting a line interactive one.

Will be pushing 200-500W most of the time, but may hit upwards of 1000W during stress tests or while running multiple games at once.
If I were to buy one of those Cyberpower UPS that go on sale for 110-120$, would it crash my system if I tried to draw 1000+W from it?

I don't expect them to work while on battery power.

What system specs are you running that will push 1000W while loaded?

The current build is 12 core Threadripper + GTX1080 and GTX1050.
I want to have room to add another GPU into the mix.

I run Proxmox on this machine, and have several VMs setup for gaming. Though unlikely, I would like to spec out a UPS that can handle all 3 gaming VMs to run at once.

However, based on the other comments, it looks like that would probably cost me a fortune....(I'd likely need a SmartAPC or something in that tier)

If you are consuming 1000 Watts sustained, you will need ~2000 VA UPS unit

I hope you have that computer running on a separate circuit (doubt it), because 15 Amps and 120 Volts = 1800 Watts per circuit. If you are constantly drawing 1000 Watts, that’s half the capacity of that circuit. You wouldn’t be able to run a second high draw computer on the same circuit

What size PSU are you using?
Do you have a killawatt meter or anything like that to see system draw?
Base the UPS off the max PSU power and monitor (and your modem)
