Topband: Desktop Power Supply Brand/Noise Question

[Gary K9GS]

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.

The XP machines are very quiet.Live and learn.
