A couple of pointers from someone who has long used UPS's on all of his electronic equipment (I currently have six in use): 1) APC and CyberPower are two trusted brands. I personally prefer CyberPower for value, functionality and reliability. 2) One factor to bear in mind (as with printers) is the cost of replacement batteries, which can easily exceed the purchase price of the UPS over its lifetime. If the UPS requires OEM batteries (or, especially, if there is more than one or if the battery is not replaceable), this can represent an exorbitant expense once the original battery gives out (usually in three or four years depending on usage conditions). For this reason, I always do my research to ensure that I can find inexpensive non-OEM replacement batteries (i.e., less than $30 net) for whatever model UPS I purchase. 3) Your TV, like any display (but most especially a plasma), will quickly draw down the power on any UPS you are likely to purchase. Unless you plan to turn the display off within a few minutes of any power outage, it is recommended that you connect it, and any other heavy load, to the surge-only (non-battery backup) outlets on the UPS. They will be protected from power surges but will not operate once the AC power goes out. Your AVR, on the other hand, will typically not draw more than about 40W when in operation and so can stay on battery-backup; that 460W you cite is the maximum draw and does not represent real-world conditions. 4) I recommend you either get two smaller UPS's or one larger-capacity unit with at 10 or 12 outlets (5/6 battery-backup and 5/6 surge-only). One of the larger models you could consider is the CyberPower AVRG900U. It has 12 outlets, supplies 480W of battery power, and has available non-OEM replacement batteries, such as this one (about $25 shipped). There are plenty of other candidates, of course; you just need to do the research. Good luck!
