Honestly, I’m not 100% sure. I don’t have a way to monitor just the stuff in the rack as the UPS also powers a lot of other stuff in the house. Either way, I’ve worked to make everything fairly low power, or at least as low power as feasible. The things that use the most power is the disks

I can tell you its less than 800w though, as that’s the lowest the UPS goes at night. But that also does include both me and my wifes desktops which stay on 24/7, and an Apple TV, and standby power for all devices etc
