Re: The Hall of Shame - Badcaps Photo Montage
I don't think it had FETs there; not only do the pads look like nothing was soldered there, but he said the board still works great, he just put in the spare pile when he noticed the caps. (knowing it might not work great for much longer. heh.)
I'll ask him about photo permission next time I see him.

Re: The Hall of Shame - Badcaps Photo Montage
Mentioned bad caps on irc to someone, and he got this photo...
http://www.rifraf.info/images/hp_caps.jpg
More "TMS" caps, this time out of a HP system. he can't find any other brand on them either.
Willawake, want to add TMS to the photo montage?

Re: Buying brand new boards?
because heat sinks should NOT, under any circumstances, get that hot.
More likely the caps burst, the VRM fets shorted, 5/12v got dumped to the chip, THEN the chip got so hot as to melt the solder.

Re: Leave on, Turn off
I have everything except the laser printers and the ceiling lights on the UPS... and I mean EVERYTHING. the battery chargers for my cordless tools, my bedside clock, electronics workbench (not about to plug my digital LCD 'scope into plain power!), my stereo system (which draws more than any of my computers... heh), everything.
6-8 hours runtime based on what's turned on... plenty to keep everything running through most outages, or give me time to lug the generator out of the garage if it's going to be out for a while.

Re: Deer DR-250ATX Power Supply
I posted some pics of a burnt deer supply a while ago... exact same thing, slightly bulging rulycons, 2" black spot on the board of obliterated components...

Re: Help Identify burned cap
It's unlikely the mov is the cause of it not functioning, unless the only symptom is blowing the line fuse.
More likely there was a lightening strike / other power surge which toasted both the mov and something else...

Re: Soltek
That would explain why I've noticed most supplies don't have -5v.

Re: Soltek
Actually, I've noticed a LOT of supplies don't seem to provide one or both negative voltages, or they float at totally random things.
...and haven't noticed anything miss them. heh. systems seem to still work perfectly.

You'd like IQ and Choyo caps. they also just squirt out the bottom. I have some photos of them on this board somewhere...

That's a reasonably good sign; the fets aren't a dead short.

They're bad, but no brand...
Got this board in the recap pile yesterday... Any guess what these are? (other than crap, I know that much!) Checked the brand-sorted photo collection, and didn't see them...

Of most interest is the two in the middle, that have lifted the cans clear off the plugs, making them look taller than the others.
