That one that read only 27pF was bad. It might still make a good replacement for a ceramic cap, though

Re: ocz 420 u12 swollen caps
Seen worse, especially the small ones. Recordman is some with aprox. 150 ohm ESR. Or the next one which did not have any capacitance, any ESR, it was probably burned inside

Re: ocz 420 u12 swollen caps
Hello,
I have news i just replaceded the bad big caps in my PSU (470uf,1000uf,2200uf,3300uf,4700uf,2200uf) and B4 that my comp was pretty slow and now he is dam fast again
here some pics of the dead dam caps!Attached FilesLeave a comment:

Re: ocz 420 u12 swollen caps
Hello,
I got an idea that the small caps i will get from other PCBs includ the 0.47uf that hard to get, so what do u think about it?Leave a comment:

Re: ocz 420 u12 swollen caps
@predator
when you list caps, you should include the diameter.
some come in more than one diameter and if you get the wrong one it wont fit.
Behemot showed how to list caps.

Re: ocz 420 u12 swollen caps
There are RS 3300 uF/16 V, 10 pcs for replacing those 2200uF, I just forgot to write they are 16 V.
I'll have a look for those 4,7mF, I am not in the shop ATM, but I don't think there will be any significant difference. First, even 3300uF KZE have very high RC/low ESR, probably much higher/lower than original caps. Than, they are on +3,3 and +5 V which are almost not used today. Due to low loads on these rails the ripple will be practicaly the same.Leave a comment:

Re: ocz 420 u12 swollen caps
Thanks. I can offer these:
5x NCC LXZ 470 uF/16 V D8x15 mm
5x NCC KY 1200 uF/6,3 V D8x20 mm
10x Samxon RS 3300 uF D10x30 mm
5x NCC KYA 3300 uF/6,3 V D10x25 mm
5x NCC KZM 47 uF/35 V D5x11 mm
3x Nichicon PW 4,7 uF/50 V D5x12 mm
2x Nichicon VZ 0,47 uF/50 V D5x12 mm
2x NCC KMG 1 uF/100 V D5x11 mm
5x KZE 3300/4700 uF 6,3 V D12,5
The bold ones are general purpose, the italic I am not sure how many of each (4,7/3,3) I have but I surely have 5 pcs alltogether.
Complete price for these incl. priority airmail shipping to Israel is 471 CZK or aprox. 23,3 USD.Leave a comment:

I know I've been a little scarce lately (like the last 2-3 years), but I'm still here and still doing my thing with fixing PSUs.
For today's considerations, I have a Seasonic B12 BC-550 [A551bcafh] 550 Watt ATX power supply for you (click on links for full size images).

It's a modern ATX unit with fixed (non-modular) cables and an 80-plus bronze certificate. Here's the label:

Hello,
First, I am a complete noob with high voltage stuff. I'm learning, but I need help by someone looking over my shoulder.
I recently came into posession of a Heathkit IO-4205 5MHz Dual Trace Oscilloscope. The documentation is copyright 1978. I'm told it works.
I opened it up to check the caps before I applied power, and found the following black caps and wanted to know what they were. They are on the power supply board. I was able to read the name and model and came up with, "Nytronics 162J-1, 0.1uF, 20% tolerance, 2000VDC."

Hello!
I have two projects on my work bench. One is a friends dead JBL Xtreme speaker with a blown voltage regulator and corresponding bulged and shorted cap. That cap has clear markings so I know what replacement I need for it.
The other project however is a whole different deal. It's a Zoom 9000 guitar effect from the 90th that has developed a devil hound howl when there is no input from the guitar. I'm guessing caps problem. So, since I don't really use this effect anymore I thought it would be a perfect project to learn on.
I have studied the board and... -
Normally, I never post repairs this quick after I do them, because… I am usually very slow. But today, I’m making an exception here. Why? No idea. Perhaps only because the repair details are still “fresh” in my head… which is ironic, given this is a 16 year old monitor that hardly anyone will care about today. It is new to me, though.
I picked it up last November from someone on my local Craigslist. It wasn’t very close to where I live, but was close to a family friend that I had to go visit anyways. So after watching the posting on Craigslist for a few weeks and seeing it getting...

Good evening
I recently aquired a rev 1.1 Gigabyte 60XT, and was suprised of the amount of leaking caps for a motherboard of the P3 era. Especially the way the 330µf caps seems like the housing discolored even.
Now, there are some 3300µF 6.3V KZG series around the CPU. Would it be OK to replace them with something like EEUFR1A332 ? (Panasonic FR 3300µF 10V). Or was this board designed around very low ESR caps?
But I was also suprised about the bigger boys, which are 330µF 25V.
Could it be they used 25V caps because they were cheaper / available at that time?...
