PNY Geforce Ti4200 card... Are these considered "solid" caps? You can see we lost a FET, too.

nope they are not -
Re: NICE -- are these considered "Solid" capacitors?
They have vents, solid polymer usually not. But probably there should be some solid polymer caps. On my old GF4280 there were only Oscon polymers. And it is runing fine so far.Comment

The vents are pretty much a tip-off. Polymers don't have the liquid electrolyte to generate hydrogen gas, hence no need for vents.PeteS in CA
Power Supplies should be boring: No loud noises, no bright flashes, and no bad smells.

Re: NICE -- are these considered "Solid" capacitors?
There are exceptions to the rule. I have seen for myself some Fujitsu solid polymers that have a K vent on the top. Polymers can bulge too, though usually not as violently as electrolytic caps - it's caused by the seal on the cap being imperfect and moisture in the air getting in.
Here's a pic from my own board. (The yellow ones are Fujitsu, the black ones are Rubycon). The Fujitsus seem to be bulging ever so slightly...
You know there's something wrong when you open your PC and it has vented Rubycons...Comment

i have seen those fujitsu polymers bulging badly and high esr on lots of asus a7 boards.Comment

Hi, I have a question regarding a motherboard with SS capacitors that I'm having trouble with. Every now and again it would give overclock failed at boot even when not overclocking.
Recently more often, and the last few weeks at every single boot. It seems like the typical capacitors needing to warm up, then everything is fine.
Weird thing is the capacitors are all solid state. Do SS capacitors degrade the same way as normal caps? Is it worth trying to recap the board?
I have already replaced the PSU.
The board is a gigabyte x79 ud3.... -
Hi, I have some 32 bits computer motherboards that need repair, as they fail to
power on.
Here are some examples :
(N.B. "capacitors" indicated here are electrolytic capacitors located in the onboard
switching supply area).
(N.B. #2 : I could not find a 3300 microF aluminum-polymer with a higher voltage
than 6.3 V.)
1 - Motherboard #1 : this is an Asrock K7VT2 (socket A) that still works well. To put it on test
I replaced capacitors with aluminum-polymer.
3300 microF/6.3 V. x 4 replaced by 3300 microF/6.3 V. (KYOCERA... -
hey all, iv got my favourite battery charger here which iv had for many years probably 15 years now or maybe even more. it still works good but thought id open it up to clean the dust out of it, lots of dust inside but now its clean and noticed 4 capacitors inside it and wondered if i should replace them.
it has inside:
2 x 47uf 16v caps 105c branded as Su'scon (lol sounds sus to me)
2 x 470uf 16v LZ105c branded as G.Luxon
not heard of these brands are they any good?
iv attached photos of the charger and the board inside for an idea on the type of... -
I did not have any 27uf @ 50 volt capacitors but one nice thing is that it has enough room for two capacitors in parallel a 22uf and a 4.7uf @ 50 volts 22 plus 4.7 equals 26.7uf which so very close to 27uf I will show some pictures of it sometime tomorrow
This is one of the shit est boards I seen in a very long time and it was the daughter board the traces just lifting off the board I had to use the capacitor leads to repair the the traces and the main board is not any better because I had to repair several traces for the daughter board to the main board
After all of... -
I have a 2007-era Panasonic VHS combo that is full of of Elna RJG capacitors. I am trying to test the capacitors to diagnose the machine and then select replacement capacitors but I can not find any datasheets for them. I did find a Elna catalogue from 2007-2008 but there is no mention of this capacitor series. Where these specially made for Panasonic and so not made available to the public? Any ideas what to find out what the ESR values should be without the datasheets? They are all between 10V and 50V and 47uF and 1800uF. None are leaking or bulged but I know that they need to be tested to be...
