I had big problems with the Zalman 400W PSU unit. Not really a problem with the power supply itself, but more a matter of it not sucking enough heat out of my case. Having a few high heat devices (Athlon XP 3000+, Radeon 9800) and not the greatest case for airflow to start, the system was running at extremely high temperatures, causing crashes at regular intervals. You'd probably want to augment the cooling in your case if you go for this supply; I'm not sure if I'd really consider it a "silent" PSU for this reason. :P later, Steve John Anderson wrote: > On Wed, 2004-03-24 at 08:20, Mark Williams (MWP) wrote: > >>Really the only thing you can do is invest in a good quality external DAC and >>run a SPDIF (optical preferably for ground isolation) signal to it. >> >>It seems a lot of high quality soundcards now are quoting the S/N and other >>stats of those of the DACs used on the card, not by measurment of what actually >>comes out of the back of the card. >> >>The main problem is the power supply in the PC. >>Its just far too noisy to be able to produce good quality audio. > > > Would using a good-quality power supply make a difference?
