Fuses can explode in this case (I have seen it in real life). The extreme
heat they produce during the short time is so intense that you actually
blow up the glass around the fuse. heat+gas == expansion
Good seconds are the capacitors, better not inhale those fumes.
If you have a power supply with a popped fuse _DO_NOT_ replace it. Doing so
might cause spectacular but not so nice side effects besides the explosion
hazards. The fuses are there to prevent fire not overloading.
When switched power supply's go there is no use in replacing parts, if one
part goes it takes the rest with it. I studies electronics 8 years and have
a fair idea of what this is about.
Every program has two purposes one for which
it was written and another for which it wasn't
I use the last kind.
