I’m looking to buy ups as I have few power outage (last between 1 to 5 seconds max) where I live but I have never used one so don’t know what specs should I check for

Ideally I will plug my 3d printer (about 100-160w when printing), a pi 4 with nvme drive (no idea of wattage) and a mini pc with n100 processor (around 10-20W)

Thanks for your advices

    Actually I could even run Klipper on mini pc but would need a very long usb to reach printer and thought it wasn’t ideal. As for the mini pc, I’m running proxmox but I’m far from being an expert so not sure if I can manage CPU scaling.

      USB has some serious length restrictions, but you can either add a repeater (which in this context, is probably a hub) or use an optical cable with transceivers at each end, something like this.

      The hub is probably cheaper if you just need one extra hop.

      I am too, and it is really easy to do so. Look up “Linux cpu governor”. NUT (which is the most common UPS management software for Linux) can execute commands, start timers at different events from UPS.
