There's an easy way to know when your PSU needs replacing, as I found out on
Sunday. It's when an internal capacitor that used to look like this:

Makes a *very* loud bang that got the neigbours wondering if I *do* belong
in this nieghbourhood after all, and ends up looking like this:

Those caps are 35mm high and 20mm in diameter and made of quite thick
aluminium. It reminded me of a 12-gauge shotgun.
Luckily I was just plugging it in at the time (with the covers off) so was
able to unplag it straight away. As in a nano-second. <g> Nothing else was
hurt.
That was a 250W PSU that's in the machine I use as a test-bed, I'd been
wondering if it had enough grunt in the last week as things didn't seem
quite right. (In fact I think that's what triggered it.

) I'd just
fitted a SCSI card (no attached devices, just the card at that stage) and
was hoping to let Windows find it and install drivers.
Fortunaetly I'd thrown out a non-working Enermax PSU the week before and,
just before I did, I decided to look inside. I saw a pair of big capacitors
with the word "Rubycon" on the side and know that they're top-quality (and
expensive) caps. I unsoldered them and hadn't got as far as putting them
away, they were still by my soldering station.
On examining them I saw that they were the same value as the one that blew.
I replaced the pair in the PSU with the Rubycons and the PSU and PC started
right back up as if nothing had gone wrong.
Hehee! I guess that doesn't help you much though. Unless you fit a SCSI card
and see if it blows?
