USB Cable with No Power


I have an externally powered QuteHD DAC and so I was thinking why would I need the power from my pc to the DAC?

Would it be a good thing to get a USB cable with the power leg disabled?

Is this even possible and would it still be USB 2 capable?

Elijah audio make one that's really nice. They also make one that has a separate battery supply for the USB 5v
If the receiving device does not use the power then it will not be sucking power via the cable.
Just like your household outlets are wired to provide power.. if they are not in use then they just do not have power flowing through them.
So no need for a special cable.
hmmm...okay, that makes sense. Thanks.

Gosh, talk about over thinking things.
