The 15 amp rating doesn't tell us much. However, the outlaw 7125, has the potential to draw 875 watts which is significant. Klipsh speakers are very efficient, so unless you plan on blowing out your eardrums, you'll likely never push the amp to max pwr output. The xbox 360 and hd dvr have a negligible draw I'm sure. I suspect the hdtv doesn't draw a terribly large load of current either. If you're wondering if you'll exceed the 15 amp capacity of the conditioner with the equipment listed, the answer I believe is no. You should be safe.

It would be helpful if these marketing goofs would provide useable information in the specifications for their products. I tried to find a max. power rating for any of the internal circuits of the Monster (online), but found nothing. Ito wouldn't hurt to contact Monster and check out their customer service. I have an old Adcom ACE-515 AC Enhancer that has a max. pwr rating for the high current outlets(2) of 500 watts. But this is an old 80's vintage conditioner. I strongly suspect the Monster is a more robust unit.
