I just got my hands on a 5090 and while I was setting it up and benchmarking the system, I realized that my CyberPower UPS is only rated for 1000W. Even though I have a 1600W power supply, the UPS alarm goes off, indicating an overload. Currently, I have my computer and a 4K OLED monitor connected to it, and I want to keep both devices protected. While gaming, I might be okay, but I'm looking for a UPS that can handle around 1500W to avoid future issues. Does anyone have recommendations or similar experiences?

There don't seem to be many consumer-grade UPS options that are around 1500W in a similar form factor to your 1000W one. The commercial/server rack-mounted ones are definitely larger.
You might want to check if the UPS is strictly rated at 1000W for all components. Try plugging in your monitor into a surge protector instead and see if it still triggers the alarm.
A 1500W UPS is only going to offer about a minute more runtime than a 1000W one in most scenarios, so your options may vary depending on the brand and build.
That really depends on the specific model. For example, my 900W consumer-grade UPS runs for about 2 minutes with a 400W load, but my commercial-grade UPS lasts around 5 minutes even with the same load since it has more batteries and is meant for higher capacity.
I also figured it's probably fine during normal use, but benchmark tests really push limits on the power draw.
That makes sense. I’m hoping my regular use won’t hit that 100% draw often, but it's something to keep in mind for the future.
