Looking to purchase UPS

Hi All,

Apologies if this is in the wrong community.

I'm looking to get a UPS for my home server. It runs Homeassistant, Plex, and a few other things. I mainly need something to protect from power flickers/blips, and for it to allow a proper shutdown for prolonged power outages.

Here is the power useage on all my devices:

• Server: 350w
• NAS: 90w
• Router: 42w

Any info on what to look for or which model to buy would be greatly appreciated.
