Power consumption in electronics

[apac]

So I'm in a disagreement with my roommate about my HT system. My Onkyo receiver is speced to output 70W/ch maximum continuous to each channel, who knows how accurate that is. Anyway, when running that hooked up in stereo to 2 floor standing speakers, playing music from my xbox, and navigating the music on my TV, about how much power does that consume? Say...compared to a PC, or X number of 60W lightbulbs on at the same time.

450watts

edit: what size tv?

here we go....

I would say constant ~ 250w peak 450w

 

[ElFenix]

constant? i would say you're probably outputting less than 1 watt per channel.

So...where do these estimates come from?
