I have purchased a few Cyber Power UPS systems and have had no complaints yet. I have not invested in a sine wave option just yet, but this model is basically the same as one I use for a similar case to your setup, just with sine wave as well. CyberPower Systems PFC Sinewave Series UPS (CP1500PFCLCD); 1500 VA, 1000 W, 120 V; 12 Outlets & 2 USB Charging Ports; Coax - Micro Center
PC Gamer also released their yearly update for battery backups just 2 weeks ago and ranked this model specifically at the top of their list for most PC gamers. The best UPS battery backup for PC gaming in 2023 | PC Gamer
+1 to Cyberpower UPS, never personally had an issue with one that I have and have rarely heard of issues with them in general.
https://networkupstools.org/stable-hcl.html is my go-to, and anything that meets at least a 4 star rating here, usually 5 though. I have an Eaton 5SC and it works nonstop. I need to replace the fan in it with something quieter eventually.
Also, some UPS devices require a NEMA 5-20R so keep that in mind if you look for anything more on the industrial side.
Micro Center unfortunately, does not sell Eaton products, but maybe our Home Office will look at their products as SMB/ Enterprise solutions.
