To answer your question; all that test is the switching to prove the power supply turns on and can power a fan. It does not prove that it can power up everything else in the computer. You can buy a power supply tester which puts a simulated load on the power supply or most computer repair shops have one for testing power supplies.
Exactly, Its a quick and dirty test to see if its completely shot. If it won't turn on thats a very good sign that you need a new power supply. Even if it does turn on, it could still have issues. I do believe the OP has already done that. There are two threads on the go dealing with this problem.
