That one at Best Buy is better than nothing but minimal. If you have a desktop, you can look at the wattage of your power supply. Although that's a maximum rating, get a UPS as large or larger. My computer is nothing special and my UPS is 900 watts. Notice Mario said he paid almost $200. So did I. And I don't have the devices causing a voltage drop on my computer circuit that you do. I had the electrician install two separate circuits, one for music/computer equipment, and a different one for the air conditioner. You can go overboard with this stuff, but I ran an electronics store in the late 1970s and I have plenty of stories...
