    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.

    Cool, I was worried as my other half had bought this gadget that measures how much power things draw and when they put it inline with my dvr/am21 it looks like it eats 50w.

    Was trying to decide which to battery backup and which not since only have 4 that are. Would these be the best choice - dvr, swim, amp and tv? The other 2 rooms if the power flickers are going to reboot since not on a ups but if power drops from that power/swim deal the main unit wont be able to handel 2 signals on one wire, correct.

    Backup the DVR and the SWM, and put the TV and the amp on the protected outlets. The TV and the amp will crush that size UPS. No reason to put them on battery backup.

    Aye, Put the DVR and the SWM PI on the UPS. If you don't get both you'll probably still have problems. Don't put the TV or Amp on the ups tho as you are almost guaranteed to go beyond the max capacity for the UPS and it will just shut down when it tries to switch to battery and provide no back up run time at all.

    I use a APC Smart-UPS3000. It is a 3000 VA, 2700 W, UPS and powers a 50" LCD, AV Head, HD-DVR, Blu-Ray, IR Distribution and Subwoofer for well over an hour without issues. Overkill, but I don't worry about not watching TV if the power goes out.

    Hum, I had hopes it could handel things. Roommate put his killowatt meter toy on the regular surge which has everything amp tv dvr am21 and misc running and it said was only pulling approx 240w. Since was planning to remove the 21 till winter that should drop the load by about ~20w and the SWm and deca would add about 15-18w I thought would be safe.

    You could hook it up and try. Worst that is going to happen is the UPS shuts everything off like the power went out. Do keep in mind that the power draw from an AMP especially is going to depend on what it is doing at the time. On but nothing playing is going to use a lot less power than when you've got a bunch of surround sound stuff going and the volume cranked while watching a movie.

    Just as a loose guide, I have a 1500VA UPS, and with the 2 DVR's, 46" TV, Stereo, SWM, and video processor, plus router, cablemodem, 1gb switch, and two external eSATA drives, it powers the system (550W draw) for 9 minutes. Turning off the TV and stereo triples the time. The 9 minutes is an actual power failure test :) Pretty much was right on the money with the time displayed by the UPS.

    Id go with the suggestions and leave the TV and stereo off a 350W'er. It just wont have enough reserve to do a good job.

    Stereo/Amps should always be left off the battery unless you have a very good quality large unit.

    Their draw might not be much, but fluctuates a lot and can spike.

    Depending on your sound system I had to remove my Onkyo tx-sr876 from my cyberpower 1000. The receiver can draw 140 watts x 7 when cranked to 0 dB. All I have on the UPS battery now is HR24 DVR, SWM plug, TV LH-90, external esata hard drive. I tried it without the TV that draws 145 watts and still could not handle it. I really need a second 1300 UPS minimum for receiver and bass amp that draws 1200 watts combined when cranked to movie level 0 dB.
    Now I know why my hearing test keeps going down hill.
