Default Testing ATX power supplies

My PS smoked & blew up. I replaced it with one said to be good. Everything
is still dead, no fans, lights, nada. Since its an ATX, is there a way to
test it on the work bench to see if the voltage outputs are present? Someone
told me the only way to test it is to hook it up to a known good Mobo.
Surely there is another way?

Thanks

Did you change the fuse in the plug?

Although it does not test much, you can determine if the PSU is alive by using an
ATX tester such as this:

or you can even try this:

This unit is a little more functional:

Good point....I've seen folks scratch their heads over a 'no power' problem, not
realising there is a rocker switch on some PSUs. Also have seen the voltage switch
set wrong (the red 115/230 switch) cause the 'no power' problem.
