two UPS questions
1. is getting a UPS for a home theatre system a good idea ? i have two setups id like to put on a UPS, a 53inch widescreen rear projector (with associated receiver, dvd player, 2 sat receivers, 1 cable receiver, computer), would a large UPS like the APC 1500va (800watts i think?) be enough to handle this? similarly i have a 32 inch CRT tv with a bunch of attached devices (receiver, game consoles, sat/cable, computer) that i would like to put on a backup too. im just not familiar with how demanding televsion are, i imagine they are quite demanding
2. a good UPS seems to incorporate three functions in one... battery backup as a main function and as secondary functions: surge protection, clean power (voltage regulation). my question is how do the secondary functions on a UPS compare to dedicated surge protectors, or dedicated clean power systems (in the same price range of course)? for example, i paid something like $150 for my APC 1000va 600watt UPS, but it only claims a rating of 420 joules protection against surges. my $30 surge protector claims something like 3000 joules. similarly, i have like a $150 monster power for my home theatre (yes we all know monster is way overpriced), and i wonder how that compares to the voltage regulation in my APC, not to mention the monster also has about 3000 joules protection. so basically my question is: UPS's are obviously great in their battery backup role and in the role of making up for undercurrent, but how great are they really at protecting from overcurrent (surges) and at providing clean power? is it a good idea to set up equipment with a good surge protector/clean power unit daisy chained with a UPS, or is that overkill?
