Computers and computer components are regulated by the FCC.
They MUST NOT cause interferance to licenced radio services.
(like the radio stations you are trying to tune in.)
Make that clear to the vendor you got the power supply from!

I bought this antenna on a 30 day trial, and just got it about 12
hours ago. So far I'm not at all impressed. I live about 150 miles
from an AM station, at 810, in the SF/SJ Bay Area, which has a
marginal signal, but usually listenable. Putting a new PSU in a PC
about a month ago increased the noise in AM radios 70-100' from the
PC to an almost unacceptable level. I had hoped the antenna would
boost the signal enough to knock down the noise. There are times when
I can get a good signal from the station, but certainly less
frequently than before.



Any rf noise put out by the computer ps is going to be picked up
by your antenna as well as the radio station you are trying to hear.
So a better antenna (if your new one is indeed better) wil just pick
up stronger power supply noise. It's moslty a null situation.

What you need to do is get that power supply fixed or replaced

I think the only solutions to the PSU problem is to buy a much better
one. As I mention above, that's probably a losing proposition. I doubt
after 6 weeks they would take it back. It might be worth a try though.
Note my comment above to someone a few moments ago that this seems to be
a household circuit dependent problem. Another PC in the same room works
fine until I plug it into the socket that I first noticed the problem.
