This is the new 2016 revision of the
Gopher CPS-3205C. Gopher has addressed some of the issues I found in the
old revision and sent me their latest for review. You will see a tear down as well as various tests performed on this power supply.
Top performance cost ratio. High power density, smallest and compact.
Aluminum shell, lower EMI
