White paste in my psu?

I got a new psu, and I looked inside and it looks like there's some, errr, white paste in there in some places. :eek: It looks a bit suspicous, is it a sign of leaking capacitors is it perfectly normal? I don't recall seeing this on other PSUs. Everything else looks fine though. :confused: It's retail and has never been used, atleast I hope so. :rolleyes:
 
Can't get any pics as I don't have a digital camera and no scanner. It looks pure white though, not the glue-ish transparent kind of white that I've seen on some pics of leaking capacitors.
 
could be thermal paste from the heatsinks inside. I ripped apart a Compaq modular 600w power supply from a server once (it was dead already...so no...I didn't do it for the hell of it) and there was white paste everywhere inside. Like a blind man was trying to apply it to the heatsinks. Horrible it was. shit gets on everything too once you touch it. Even if you wipe your hands,...somehow...that shit gets elsewhere.
 
It could be glue.

Large parts, like capacitors, are top heavy and this can put a lot of stress on their leg wires during transportation.

The manufacturers are aware of this - and they will often put big blobs of glue (usually a white plasticy stuff) on these big components. This reduces vibration and makes the whole thing stronger and more reliable.
 
Thanks ChumpusRex. :D The stuff is indeed mostly on the large parts in there. I guess I don't have to worry about it then... I'll find out when the rest of the parts arrrive here.
 
this sounds perverse...but can you poke it with a small rod? (see...hehehe...told ya so :p )
if it's hard, it's glue, if it's soft and smears it's paste.

god this post is wrong on so many levels...heheh....amusing though :p
 
This is just thermal paste dude, no leaky capacitors. Theirs alot of shady stuff going on in power supplys and i would personally prefer a much cleaner look inside. Obviously the manufacturers think they can get away with this type of stuff.

On that note my antec is fairly clean inside so go figure. Ive seen some horror storys from micro power supplys from shuttle cases that would make you stab yourself in the heart with a hot soldering iron though.
 
It's not thermal paste. It's a glue used to reduce vibrations. Most of the times, from what I see, they use a thermal pad between the mosfets and the heatsinks, and capacitor leaks are brownish and nasty and the capacitor is bulged.
 
i saw the same crap at Antex. They were selling some 600w psu's and all of them had this glob of white paste in the same location. My guess, it's some sort of thermal paste as suggested already. It cant be glue...its texture looks just like TP.
 
normally people don't just put huge globs of thermal paste on a component. They do with glue though, and sometimes the glue looks like certain thermal paste.
