Identities Of Capacitors

[shovenose]

That's the same card I have!
But I'm not going to take it out of my computer now lol.
I don't know what the cap brands are but maybe c_hegge can help you.

@Duckula, the caps on that motherboard are Fujitsu polys. They are fine.


@Goober, I think the red one is a Fujitsu polymer and the blue one is a Chemi-con polymer, although it could also be a nichicon, all of which are reliable. I'd need a better picture to identify the electrolytic, though

EDIT: I found a somewhat bigger picture of that card in the internet. That cap I couldn't identify looks like it might be a chemi-con KZG (which are unreliable and often fail without any visible signs), but I still can't say for sure unless I can see the markings

Thanks c_hegge.

[Goober]

Hmm, that helps c_hegge. TY. But I still do not know which cap that corner one is.

[duckula]

Any idea about what brand are those caps with black marking on the zotec z68 motherboard?

[c_hegge]

I can't quite make out the markings, but they look a bit like elna (a japanese brand).

[duckula]

Thank's c_hegge.

BTW, I don't think this mobo has a 24-phase VRM as they advertise. There're only 14 Driver-Mosfets on the board. (I don't know if there're extra mosfets on the reverse side of the pcb.) I'd say it's a 12+1+1-phase VRM. 12 phases for the core, 1 phase for the memory controller and 1 phase for the integrated GPU.

Mm, i believe the whole phase thing has been turned into a marketing scheme. Each synchronous buck converter will be composed of two mosfets. If the power supply has more "phases", that means several converters that are switched in succession, each of which requires two mosfets. Hence, the number of phases is number of mosfets divided by two.

[duckula]

Thanks for the explanation.

emm... does LG actually make capacitors?
