My M system had an intermittent "click" sound since Dec 2011. Suspecting that a bad PSU should be the cause, I decided to modify my G68 with an external linear PSU. Thanks to the valuable information from Nick, Condor CP498-A will be a good choice with over-engineered specification.

A few days ago my CP498A arrived exactly when my G68 started to generate a loud "click" sound when switching on. I cannot use it now and have to speed up my modification work.

Today I have just verified that my CP498A works fine. When the 5V open circuit voltage was set to 5.13V, its output voltage at 2.7A output was 5.09V. I have configured my CP498A to replace the SMPS. Next I will verify that whether my CP498A can solve the problem of "click" sound.
