I did exactly what Gary suggests to clean up the power supply on my
homebuilt octo-core machine (back when it was a dual core Pentium hi).
Corcom is one of several brands - even the best costs only ~$10. I had
to do a little surgery on the IEC connector hole in my cheapo supply,
but it was worth it!.

Hi Clay,
One thing you might want to check.
See if you can get inside the power supply...disconnect it first. Take
a look on the PCB near the power connector. There may be a space on
the PCB where you can install a power line filter....something like a
CorCom or similar. Sometimes they leave them out on some models to
save money.
If you Google CorCom you find info on the different models...just be
sure to get the correct ratings. They also sell filters with built-in
IEC connectors. An IEC connector is what the power cord plugs into.
you may be able to get one that works.

Hello to the group.I recently built an AMD quadcore machine I intend
to eventually replace my trusty XP Pro machines.
Foolishly got in a hurry to complete the build and purchased a PS
from a local shop.It supplies the power required without issue, I
have discovered why the price was so good.Jim Brown will love this
one, virtually no RFC filtering, you get what you pay for and I know
betterjust didn't realize the noise from 40m and down would be SO
intense particularly on a Delta pennantthat points back toward the
shack's general direction. The XP machines are very quiet.Live and
learn.
Question: Looking at another "good deal" how do the COOLER MASTER
PS's rate for RFC filteringor are there others brand I should be
looking at?

Will likely not waste time trying to make a Cadillac out of the Yugo
I purchased.
