subject: Testing ATX power supply

JH> when that short between those pins is released.  I doubt at that stage
 JH> that there is a way to do much of any meaningful voltage readings on
 JH> the other pins, since there is no load attached to the PS, and its
 JH> voltages will not likely be stabilized to near what they might be if PS
 JH> were connected to a MB.

With the AT power supplies I used an old MFM FH hard drive as a dummy
load so it would regulate.

 JH> What I'd like to have for ATX PS testing is a box with
 JH> multi-lightbulbs, and pin points for reading voltages, which would test
 JH> all of the various voltages at one time, during reasonable power
 JH> loadings.  But - I've never seen such a tester offered for sale.

If I get a dead board some day I'll torch the connector off it.  With
that in hand something could be cobbled up.  I like your light bulb
idea.  Auto parts should work.
