I just pulled a smoking Dark Knight Titanium (550W) power supply. It has 5 very bad caps which I think I could replace. However, looking at it closely, one of the circular copper-covered coils is heavily burnt at the point where it is soldered to the pcb. After pulling the pcb off the damage is local to the coil where the copper goes to the pcb, that area is definitely burnt but looks mostly superficial. Looking at the soldering quality from the underside is really scary. It looks like whoever did it had a giant squirt-gun of solder and just laid it on there. And then there's a jumper wire that got thrown on there for some reason. Any advice? Maybe I should just dump it? It got replaced with an Antec 430 which is barely better.

Re: Anyone familiar with Dark Knight?
Yes powmax. Throw it away. No use in recapping it is a terrible psu no matter what. The antec is a decent power supply. Might as well just recap that unit.

Re: Anyone familiar with Dark Knight?
Take us a picture first, I'd like to see the guts of one of 'em.
Also, there is a possibility you could save the case for another PSU's guts, swap out cables and connectors (even make a motherboard extension cable for bench testing), salvage the heatsinks, and definately scavenge the fans. Just pull the little sticker off the backs of them, put some sewing machine oil in there and they should be good as new.Comment

Re: Anyone familiar with Dark Knight?
Ya know, I got other pc power guts strewn all over, plus I'm working on a Dell USFF machine. This is just what I need to fiddle with. Does anyone make a decent kit for replacing the guts of one of these things? Here's some shots; on the pic with the obvious bad caps, there is a coil colored black. The problem area isn't very visible but its just at the base of the part. Anyhoo, you're right, I can salvage the 'sinks and the fans, the other stuff looks no good so I need something to stuff into there....BTW, check out the top notch soldering, I think my 7 year old kid could do a better job. Sorry about the mediocre pix, they came off my 'droid. If y'all want more pix, sing out before I hose this stinker away.Attached FilesComment

Re: Anyone familiar with Dark Knight?
Which model Antec did you replace it with? SmartPower, TruePower, Earthwatts, or Basiq 430w?Comment
-
Re: Anyone familiar with Dark Knight?
Basiq 430, it was inexpensive. I don't say cheap because I got it retail rather than online as there was a time requirement. It wasn't the cheapest unit but wasn't the most expensive in the class either.Comment

Powmax... Maximum Pow.
First time i see a burnt filtering toroid in the secondary. Canicon capacitors, small board, garbage soldering... lovely. Keep the fan, heatsinks, transformers and primary capacitors. Throw away everything else.

Re: Anyone familiar with Dark Knight?
That would be the second time I have seen a cooked filter on a secondary and those yellow caps on the primary look like Fuckyoos to me... those are the only primary caps I have ever seen to vent and blow.
Definately junk.Comment

@Evil Lurker: I've seen a Panasonic primary capacitor bulge in an Antec TruePower... (I replaced it with another one)Comment

Re: Anyone familiar with Dark Knight?
I have one similar in a box somewhere. Has a big 12cm fan and an 8cm fan battling to cool not much.Comment
