UPS Battery Backup for Element Console

Hi, I'm looking for advice on something that will serve as a 'protector' for power blips and surges we occasionally get here.  I'd like to use a UPS style backup/surge protector to give me enough time to shut down the console in case of power loss and/or surges.  Does anyone have a suggestion on what to get? What "size" wattage protection?

Thanks in advance for all suggestions!
