Do you have and use an oscilloscope? Good, now you are ready to
start learning this stuff. Take lessons on transistors, pulse width
modulation, diodes, filters, .... You will not believe how many
functions are required in a power supply if you did not read its full
page of numeric specs. To fix a power supply means you understand
what those specs say. Implied - how many self proclaimed computer
'experts' do not even know what a power supply does. They think it
only provided voltage. Learn how complex a power supply really is and
the many functions it performs.

Of course, learn of the power supply controller – another component
that many do not even know exists.
