This Antec Neo HE550 is a lot worse off than i thought

[Pentium4]

This is the same PSU I recently posted in the PSU build quality thread. I got it for free and the computer shop cut off all the wires. I originally only saw one bad cap but when I took the PCB out, it looks like there are some other things wrong with it.

Looks like something here started to burn



This was the piece of plastic that was in between the secondary coils and heatsink from the picture above.....that thing got HOT!

Here's the modular plugin board, doesn't look too good

Soldering is meh but doesn't look like anything got too hot under here

What do you guys think happened? You'd think this thing would shut itself down before it got that hot, considering it has SCP, UVP, OPP, OCP, and OVP

With no OTP, though, it won't shut off from overheating.

That coil behind the bad cap looks like it is really roasted.

Think it's a goner?

You could probably save it, since the PCB doesn't look damaged. You'd have to replace the coil and caps, and remove any glue.

I think it could be saved too, sometimes when a cap goes it will overstress the filter coils.

EDIT: Oh, and remove all that yucky Evil Brown Glue

So do you think in that top picture, nothing is fried, the glue was just going conductive? And when I get home I'll check to see if the coil is damaged. I've seen coils painted black before Surprisingly, the rectifiers on the secondary aren't burned. But then again, those things can handle insane heat.

What about the modular board? Should I just clean that gunk off it?

Thats just leftover flux.

From it getting hot?

No, the residual flux is from the soldering process.

What should I use to clean it off?

I usually just scrape it off. The darker parts a more brittle from heat. They wil break easily
