Old psu has some weird substance in it. Throw it out? (works fine)

[reniat]

I've had the same Corsair TX750 since I first built my PC 5 years ago. It's treated me well, and i've had 0 problems with it in that entire span of time. 2 days ago I bought a Seasonic Prime Titanium 850W, since I wanted a modular PSU (I realize titanium is overkill, but I had my reasons. None of them practical, but that's beside the point) to try and get a handle on cable management. 

The Seasonic is great, I absolutely LOVE that PSU. This post is about the old corsair PSU i am replacing. I PLANNED on using it for a second build (a cheaper PC to try things like custom watercooling before trying on my main machine), but when looking inside of it I see tons of gunk-looking stuff. It's on the capacitors, it's on the PFC coils, it's on the board, etc. My current theory is that it is dust that has been melted (if thats possible) and melded into these clumps. I did have the PSU facing down, and on carpet, so there is naturally going to be a lot of dust. 

 

The questions I have are: 

1) is this dust, or something else?

2) is this safe to continue using in another PC?

 

Keep in mind it was working flawlessly from when I installed it 5 years ago to when I took it out to replace it. I have no doubt it would work if I put it in again too, but I don't know if that's safe until I know what this stuff is. 

 

Here's a picture:

at first glance it looks like it's coming from the capacitor, but that doesn't explain the extra chunk of it that is on the PFC coil to the left of the chunk bridging the cap and the coil. Also, if a capacitor was leaking that badly, wouldn't the PSU stop working? 

 

Also potentially related, one of the capacitors is bent quite a bit:

That image was taken directly on top of the psu, so the angle is from the capacitor's bendedness. I don't see any leaking at the base though, and there is that cable touching it so perhaps the cable just pushed it over the course of 5 years? haven't looked inside this PSU since i installed it, so anything's possible. 

 

First time posting so if I screwed up the format, lemme know.

Thanks for any and all tips. 

 

EDIT: I just realized that the "goop" couldnt have leaks from the capacitors down, because this orientation is opposite the way it was in my case. If the cap was leaking, it would have leaked onto the fan. Is it possible this happened as I was removing it and didn't notice? I have used PSU tester on it after seeing this stuff, and it does still function fine.

That comes from the factory and used to keep parts from falling off. Its glue.

 

That other cap is fine.

i'm pretty sure thats just what they do to keep the parts from moving while vibrating

My guess would be that it is supposed to look like that, an old psu ive got lying around has got that white substance inside it too and i think the capacitor is moved aside like that to make place for the wire beside it

Well I learned something new today. Thanks guys!

also if some did leak from a cap the top would be popped out since thiere meant to leak out of the top where that Y cut is 

 

this is if it actually vented

 

 

and this is when it has puffed out but hasn't actually vented yet

(the bottoms can also leak as well but its rarer but as long as its working fine the caps are fine)

that's glue.

 

And why did you remove the fan grill???

I just removed the grill to get a clearer picture.
