There are supplies with very high switching noise and supplies with acceptably low noise. Several were tested by the ARRL a number of years ago and results were published in two issues of QST. If you are a member, the articles are available on the ARRL web site. QEX had an article recently about converting ATX power supplies from computers for ham use. I'd advise staying away from unknown supplies, however.
