Usefullness of a external quality power (linear PSU or Battery) for USB Pci card (SOTM, PPA,...) for use with an Asynchronous, completely 5V decoupled DAC ?

Hopefully I am not missing anything, but if your DAC doesn't need 5v why feed it any? The Elijah Audio Isolate CU USB cable carries just the Data and Ground.

My bad. I am not that familiar with internal cards. I use a battery on my external convertor, but am using upgraded clocks and a low noise voltage regulator.
