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 ?

PPA USB needs external power to deliver the best quality. I tried to power it from MOBO (even powered by linear supply) but the sound didn't differ much from the ordinary USB port.

 

Cheers

I've got a PPA USB card and a TeraDak power supply to use with it, but I'm lacking a power cable to connect the two. Can anyone point me toward a USB to Molex power cable?

 

Thanks.
