Okay all I want to do is prevent my dvr from rebooting if our power blips for a second. Around here in the summer we get a lot of blips and even though the tv flickers for a sec it doesn't go off but my dvr would reboot. Anyway I have an apc unit that is 350w 550va. Just for blips do you think it will be enough for dvr, SWM and deca Inet bridge? Like I said its only for the quick blips, so the unit doesn't just keep rebooting. Anything longer and I'm not watching tv anyway.
