"Ian Malcolm"


Its *NOT* a cap, its a varistor and is supposed to clip any spikes on the
AC in.

** Nonsense.

Large electros kill spikes just like sledgehammers kill flies.

A bridge rectifier followed by a filter electro is the best spike suppressor
you will ever see.


Replace it with one rated for continuous operation at your local
supply voltage or the next time there's a surge the PSU will puke its
guts and is quite likely to take out the motherboard and/or hard drive.
There may be one across the other big cap as well and if so they should
be replaced as a pair.

** All they do is make the fuse blow if the electros are overvoltaged by
connection to a too high AC supply.
