Interference even with external USB DAC

[lbrwnie]

Hi guys

I was just wondering if you would have any solutions to this.

I have recently purchased a Topping NX2 to solve a few audio issues I have been having with my devices. First of all is with my desktop and interference because I use a old Integrated amplifier to power speakers as well as my headphones (HD 598). It was working and sounded quite nice until my PSU died, I replaced the PSU with a EVGA 750 G2 and now I am getting a lot of interference especially when gaming/putting a lot of stress on the GPU. I have tried different USB ports and the same interference happens when the amp is just plugged in via analouge too. 

I'm stumped and I'm thinking it could maybe be a weird 5V problem? 

Any thoughts?

Thanks

it's most likely noise induced by the PSU

do you have possibility to connect the DAC via TOS Link?

 

if not, try a different PSU

I don't have a toslink DAC no, don't exactly have a spare PSU either.

sounds like PSU to me, had the same issue last year and swapping the psu fixed it  Is it too late to return yours?

Just RMA the PSU.
