Can (defective) PSU affect quality of sound card output?

Hello, 

the sound of my Asus Xonar Essence STX, connected to an Edifier 2.1 Box Set, 
has once been brilliant. Recently, the sound has increasingly lost dynamics 
and turned more and more "flat" and lifeless. 

Is it possible, that this caused by an unstable power supply unit (since other things, 
that may point to this, such as temporarily irresponsive or "disappearing" HDs, 
happened in the same time)? 

Or could power supply problems only lead to the card not working at all? 

Thanks

 

How is the internal Asus soundcard connected to it,(Coax SPDIF for example)  and what is used to power the Edifier 2.1 ? 

 This Asus soundcard should already have good internal PSU regulation, so it seems unlikely to be due to the PSU of the P.C.

 

How a Digital Audio file sounds, or a Digital Video file looks, is governed to a large extent by the Power Supply area. All that Identical Checksums gives is the possibility of REGENERATING the file to close to that of the original file.

Another thing to do is to MAKE SURE the Windows mixer isn’t screwing you over; make sure your players are set to exclusively control audio. You may have set that up in the past and something changed it back.

 

Yes, some Windows 10 Updates can do that ! :$

If you suspect your PSU is broken, you should get that fixed before doing anything else. If it gets worse, it might end up damaging something or causing you to lose data.

In many cases, the +12V and +5V for all HDDs get their power from the same place in the PSU , using separate feeds , so you would expect a general failure , not just one HDD disappearing.

 A faulty, or high resistance  Molex plug/socket on  one feed could cause this to happen ?
