I'm an electronics engineer, I open faulty devices to research the cause of failure, learn from it and repair the device if it's worth the effort (not this one). People like me do this frequently. It's a dangerous practice to "relabel" a capacitor to 450V while it can only withstand maximum 400V, among other bad practices in this power supply. The failure cause was such bad soldering that the capacitor just fell off the PCB and was rattling in the enclosure. This also says a lot about the quality of the WELL brand products...
@cucuruzel holy cow. I've been trying to watch out for fake capacitors for over 10 years when I work on arcade monitor circuit boards. I didn't know they were doing this! I thought they were just manufacturing poor caps and having the fake labels printed from the start.
@@TortureBot This is a relatively newer technique: components are recovered from electronic waste and used to build "new" electronic devices. Experienced people can spot all sorts of recycled components in the cheapest electronic devices: from semiconductors (mainly power devices), passives (mainly expensive capacitors, power resistors) to radiators, connectors and even electrotechnical devices (like fans and relays). So the label should not be the only indicator of a good capacitor...
Wolf in peel of sheep
Nichicon capacitors always use an X vent, so if it has a vent and it's not an X vent, it's not Nichicon
That's fucked up
The original nichicon capacitors are color blue
No. I have many Nichicon black color original capacitors. Of the capacitors I have, only the Japanese ones are blue.
I've got tons of black Nichicon electrolytics. None are fakes. Purchased directly from Mouser/Digikey. It all comes down to the series in question.
Ok like what's the point, who opens their power supply just to see the capacitor brand.
