Eurocase Hec cap exploded

[trodas]

Guys, we all know that Eurocase PSUs aren't nowhere near good. On top of that, they use the inferior Hec caps. So, when the metal meet the meat, it could end like THIS:



(take note that the cap exploded AND broken the small PCB on the main's connector!)



(check out how the resistor was hot!)





(and the rests of the cap - well, it is not my quality macro, but you get the idea...)

Re: Eurocase Hec cap exploded

See the burnt resistor near KA7500B chip? Check the area between the two heatsinks - you'll see discolored brown PCB. That cap exploded because of too high voltage applied to it - as a consequence of auxiliary supply failure - a classic EuroCase problem - as seen here https://www.badcaps.net/forum/showthread.php?t=831
It needs some more work to fix it now - so if you have more of these PSUs, replace the cap mentioned in that thread.

Re: Eurocase Hec cap exploded

i'm very familiar with those heatsinks and those burnt components.

but in my country, usually those psus are without i/p filter and pfc. ye sthey use hec too. perhaps hec caps and hec (heroichi) psu is a different company (?)

That little bugger most've made a good bang... Hate to see what it did to the rest of the computer when it went.

Sometimes it just dies without damaging anything, sometimes it puts out a voltage spike that kills almost everything.

Monstrous! That PCB isn't fixed in a position where it would be very rigid, which means the cap in question must have struck it with a considerable amount of force.

Could you show us the other side of the PCB, where the impact took place?

willawake - he it little, tough he can do "great" things...

Rainbow - no-one is going to fix that crap Yet thanks for providing a solution, mate! And in this case, IIRC, nothing get damaged in the machine - hooray!

Shroomie - exactly my point. Maybe the cap could be used as shell in gun?

tiresias - I can't. This is pictures + short info that send me my friend of what happend to his friend. That is all

Re: Eurocase Hec cap exploded

Trodas, PCB is not good for this PSU. Be careful if want to recapp or repair this PSU.

Hehe, no way. I won't touch this one with ten foot pole
