leaky capacitors and testing the PSU

Hi
Supersparks posted this some time ago.

If you have, or can borrow, a voltmeter, then here is how to test the PSU:
Here's his link about Testing PSU voltages.

Also, while you've got the covers off the case, carefully check the capacitors for leaks or bulges - there has been a spate of capacitor problems in recent years (a bit of industrial espionage that went wrong ).
Leaking Capacitors:


Bulging Capacitors:



(SuperSpark's original post is over here.)

I've seen too many like those in the last few months.
And I understand that a "Poor" PSU will hasten the process.
Well, after I replaced the motherboard (Which looked worse than this.. I wish I took shots) in a machine and had my head behind the machine to make some USB connection the PSU just went "BANG".
I opened it up and The PSU had leaky capacitors as well.

I can just as well also recommend that you look at the voltage on the power outlet.
You see, I could compare exact twins (exact same configurations, same mobo, same PSU.. etc).
I had gotten curious and eyeballed the twin in another location. It showed nothing amiss.
This other family had no problems for many years, but they moved less than two years ago.
They now live next to the tranformators for the area and his power is way over 240 V.
This (to me) explained the series of malfunctioning devices and computers they are suffering.
