Narrow escape with Dell PSU
by Bruce Ure at 23:05 16/06/11 (Blogs::Bruce)
So I turned my 3 monitors off at the mains (all in a single 4-way), then about 30 seconds later remembered something else I had to do so I turned them back on.
After about 20 seconds I thought I smelt a sort of soldering type smell, then another 20 seconds and I was *sure* something was not right... I looked down and flames and smoke are shooting out of my Dell monitor's PSU and it starts to spit and pop.

I pulled out the mains cable and felt the PSU... it was red hot.

If I'd not been in, like if it had been on a timer switch or something, the house would probably have burned down.

No idea. Switch mode PSUs, of which this was one, all have so many potential modes of failure that some of them are bound to be catastrophic and dangerous. My money's on a capacitor shorting out and a safety cutout failing to cut out, something like that. BIt worrying though. Makes me think I need to revisit my policy of always keeping wall warts and other external PSUs on ceramic tiles to reduce the chances of them catching other stuff (floors, carpets, furniture:) alight. I used to do that but I stopped. Time to start again maybe.
