External DAC mouse noise?

[PebblesInAus]

Hi guys, I started a thread a while back about the noise coming through my headphone from the sound card.

I took the educated advice and bought a Fiio E10k external dac.

 

Why would I still be getting mouse buzz through this system? its got me baffled.

Is the usb port directly attached to the mobo? Maybe that could help

 

I once had an amp (not a dac) that was powered via usb. When the power was supplied by the mobo usb port it sounded terrible, but when powered with a phone charger it sounded perfect, but the amp was too tiny for what I wanted. I got a dac and amp now that each get their power from the wall, and its been great ever since.

 

I could be wrong, but see if you can buy a usb cable that splits power and data, and plug the power side into a decent separate usb power supply separate from he computer.

Thanks mate, thats a terrific suggestion I have a couple of USB outlets on my power board, I will try that!!!

Im unsure though how I can tell it which one (Of the spliter) to use as data......
