According to cnet the average plasma is about 300 watts, and your 50" is a pretty average size. We can take the 450 watts peak of the sub to be conservative, around 300 watts for a typical home theatre PC (500 watts + for full size gaming rig), and about 750 watts for the 608 to be conservative (6.3 amps at 120 volts).
300 watts (plasma) + 450 watts (sub) + 300 watts (htpc) + 750 watts (608) = 1800 watts or 15 amps
The question is, is this dedicated circuit for your home theatre on a 20 amp circuit breaker (with #12 wire), or 15 amp circuit breaker (with #14 wire)?
By code, you can only load a circuit breaker to 80% of its rating, so a 20 amp circuit breaker can have up to 16 amps on it, and a 15 amp circuit breaker can have up to 12 amps on it.
From my experience, the numbers above are conservative, and you should be fine with just a 15 amp dedicated circuit!
Hope this helps!
