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

Gosh, talk about over thinking things.
