The highest quality PC power supplies I am familiar with are made by PC Power and Computing. Will they improve the sound of your PC audio? Dont know.
Best powersupply for PC audio?
This is a question that I would like to find an answer on. My PC seems supplied with a standard mass market powersupply. I think that a replacement is definitely neccesary for better quality audio. But so far I have found nothing on the topic. Could anybody give some useful information on this?
