Vary voltage on input while monitoring output. It should remain constant across specified voltages.

thanks for ur help sir,but i need it in a experimental way.(i.e) i must specify all the apparatus required to test it and and also i must give a digramatic explanation of procedure and draw a sketch of the output waveform.if u could help me out it would be fine

Computer technicians do not test power supplies at that level. They check output voltages or replace the power supply with a known good unit. Interpreting waveforms requires training in electronics and practical experience. The knowledge to do this cannot be obtained by asking questions on a forum.

It depends on the kind of power supply. Power factor correcting
will have a different input waveform. The load also affects the
waveforms. For operating characteristics see the data sheets of
the various chips.

There are no easy answers to the testing and troubleshooting of a SMPS. This requires knowledge of electronics and practical experience. It is not simply a matter of comparing waveforms. These will vary with input voltage, load, and the make and model of the power supply. Interpreting waveforms is a skill and often requires making intelligent guesses.
