Hi everyone,
I still hope I can fix the first, older power supply, because the new
power
supply
stated on the box that there was protection against short circuits.


In my experience, any fuse(s) located inside the SMPS RARELY if EVER
protect
the circuit from a short condition... there's pretty much always something
else fried in the unit. Switch-mode power supplies are amazingly cheap
for
what they provide, which is very well regulated, efficient DC power. They
are also very very time consuming to diagnose and repair. As such, the
general concensus in the repair industry is to throw it out and buy
another
one. I believe you made the right choice. As another poster has
suggested,
try replacing the fuse, if there is one, then throw it in the bin.

Hi Dave, and thanks.

I must say, thinking of what could go wrong now, I fear - knowing nothing
about power supplies or their electronics - that if I replace the fuze and
something else in de unit is also damaged, it may well be that the actual
voltage produced by the damaged power supply would maybe exceed what the
motherboard of my pc could cope with. I would maybe be happy replacing just
the fuze, but the unit could cause more damage. I think I will stay with the
new power supply unit.

Thanks again to all,

Peter
