Problems with using car stereo amp in a house.

[phofman]

Second-hand server PSUs from ebay for a few tens of dollars fetch up to 100A @ 12V, used e.g. for fast battery charging by model makers. I have/use a few of these. But they typically have rather noisy fans.. :-(

Even fanless "silent" PC PSUs may be too RF-noisy

depending on the load devices involved, or just nearby.

But if cheap enough, can just try and see!

I have never noticed problems with PC soundcards, most probably average PSU is good enough.
