Description: video of a plug in power meter, showing the wattage increase from circa 65 watts to circa 80 watts when the sound of a space key on a keyboard is violently pressed

It cut the video short because of file size limitations, but the power draw is quite consistent between multiple ons and offs.

I am streaming music from Tidal on my desktop, sending it to a Tascam sound card Description: picture of a https://tascam.com/us/product/us-1x2hr/ in an active state

And into a mixer, which in turn sends it to active Adam speakers Description: picture of a https://www.soundcraft.com/en/products/notepad-8fx and a https://www.adam-audio.com/en/ax-series/a5x/

Is the increased power draw what it costs the CPU to stream and decode, or what it costs the Tascam to do it’s work, or both, or something else?

Edit: I have no idea why the sound was removes from the upload…

    Both plus the waste power in the amp, the power that actually gets turned into sound, and the wasted power in the speakers that’s slightly heating them up.

    Still, a 15W difference isn’t that expensive. If you listened to music 8 hours a day every single day, with my electricity prices, it’s $0.43 a month.

      Sweet. Thanks for your input! And if one listens to or streams music on a smartphone with headphones, the power draw is even smaller, I suppose? Would be interesting to measure with one of those USB power meters.
