UPSs also have other benefits in power outages as well, once you've shut the computer down. You can use it to keep LED lighting on at night. Charge phones and tablets. Moreover, if your power is out, you might still have 5V on your cable line -- so if you can deliver the 8-9W the modem wants (and likely similar to your router) you can still have your normal internet service. If you have a beefy enough one (we're talking $200+ UPSs here), you can use it to power a modest refrigerator for a bit, getting temps back down to proper levels to prevent food spoilage if you end up with a long term outage that spans 48-72 hours. Most fridges only pull 120-180W when they run, and depending on the temp and time of year, only run the compressor for 15 to 20 minutes at a time. Plugging the fridge into it once or twice on the 2nd and 3rd day of an outage can save you a TON of grief and food spoilage.
