Re: Did I just bought a fakecap ?
Of course they're fake.
I have never seen Panasonic FL sold to the masses that were genuine, nor are they even manufactured any longer.Leave a comment:

Re: Did I just bought a fakecap ?
1500uf will be fine, but i suspect we wont find more than 1200uf.Leave a comment:

best i'v found in 8mm so-far is 1000uf, but i'm still looking

Re: Did I just bought a fakecap ?
So, after desoldering caps what I got is:
3 died panasonic(probably not) caps, each of them lost half 800 uF of their capacity(Finally got at least LCR-T4), and got high ESR
1 out of 4 Kemet caps died on desoldering, as one output lead desoldered(or what it has done) from the cap too. Other Kemet caps survived and still got good ESR in range from 0.07 to 0.11 and 360-380uF capacityLeave a comment:

Re: Did I just bought a fakecap ?
how wide are the 1800uf caps? 8mm or 10mmLeave a comment:

Re: Did I just bought a fakecap ?
Check the polarity of the capacitors: you installed them backwards.
Asus are crazy and uses the half circle on the PCB to designate the positive side.
See for example:

Re: Did I just bought a fakecap ?
*Update*
Those caps didn't survived, maybe they are still working but they are bulged(Screen attached)...
They didn't survived because they got overheated(common problem on this ASUS P5B-VM board, saw another one for sale with same bulged caps, screen attached by the way), even original factory Rubycons MCZ didn't survived this one, so those caps wouldn't get even a chance either
Also near are Kemet A758 caps which I bought from same seller, they are still good(0.67 BYN / 0.27 USD each btw), they replaced 3 bulged and one none bulged Evercon 330uF 6.3V which were installed from factory for some reason... So maybe you'll give me an advice which poly cap to use for this board, as I didn't found any 1800uF 6.3V poly cap on Ali.

i ordered a lot of caps from digikey to repair my xboxs. one thing i ordered was 50NXA10MEFC5X11-ND caps and i think they are not polarized. will this cause any kind of a problem? i really don't want to order new caps just because of this. -
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 an ASUS P5KPL-AM board with swollen and leaky capacitors. Amazingly, it still works, but I'm guessing it won't be long before it doesn't so I'm looking to replace the capacitors. All that electrolyte is probably not good for the traces too.
Anyway. Every cap on that board that is 820uf 6.3v is swollen, so that issue is isolated to those specific caps. They're TK AWTY caps. Never heard of them but I suppose they're bad quality.
To replace them, I bought Rubycon ZLH capacitors with the exact same 820uf 6.3v spec. But when I went to test... -
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...
