I use one of my computers to play music. I have it connected to a high end stereo system ( Harmon Kardon Citation series amps) I was using a desktop style case that is designed to look nice in a stereo stand, but have had tremendous problems with the system in that case. I just changed the case for a mini-tower with a Codegen 450W power supply. Now I am getting a hum from the Sound Blaster card and from the on-board sound card. These are the same I/F cards that were in the system to begin with. The only different parts are the case and power supply. The P/S must be the responsible item. I am looking for a low electrical noise P/S for this system. Does anyone know of such a beast? I am not concerned with Ambient noise (i.e. what you hear) it's more of an issue of whta interference noise it generates.
Thanks

That sounds more like an open input than a power supply problem.
Computer power supplies are switching types and would not produce the 'hum' that you mention.
If you had no hum before you changed cases, then look for a bad cable, open input, missing ground.

You might have a problem with the motherboard grounding - if you swapped the mobo to the new case, doublecheck all the connections - make sure there aren't any extra studs sticking up off the case under the mobo. Reseat your power connections - otherwise it sounds like the power supply is a P.O.S.
None of them should give you hum through your soundcard unless they are dying.

in case you have any cables exhibiting indicators of being burnt, you maximum easily have some style of short-circuit undertaking that could reason a fire. that's terrific to be sure all aspects VERY heavily. in case you have yet another workstation, attempt putting the foremost aspects (hdd, dvd force, and so on..) on the different workstation. If those products are functioning acceptable, then save checking element by skill of element till you come across the defective one. With what you're describing, curiously like the flexibility grant is the 1st place i could verify.

You have a grounding issue somewhere. The hum you are getting is probably the 60 Hz line frquency seeping through somewhere.
