I need something for back up power for my Computer and for my TV+PS3. I dont need to just have power just enough to safely shut down my computer, i need backup power for atleast 20-30 minutes. Reason is, if im in the middle of a game online on my PS3 then if light goes or i quit the game, i am awarded a 3-0 defeat which is very frustrating plus my DNF%(Did not finish) also rises. So help me out here guys.
Which device can do this for me (UPS?) and how much will it cost? Ill be buying 2 of these devices, one for my computer and the other for my TV and PS3.
