I got an old AM2 board with 3300uf 6.3v badcaps(all). So I want to change them with poly ones. Can you give me advice which capacity should I use ? I saw on one russian forum(rom.by) that capacity of poly should be around third of current leaky caps, but I'm not sure.

no, as close as you can get - which is probably 2000uf at the moment. -
Re: 3300uf 6.3V Poly recpaing
well, i got Foxconn WinFast MCP61SM2MA-RS2HV board, it's using 5x3300uf 6.3v caps atm, but board has space for 3 more caps. Also on rom.by forum I saw reference to this forum where it's said that there was a thread which shown that some gpu vendor changed 1000uf caps to 330uf poly ones. I think high capacity used for higher ripple current and lower ESR, so as poly caps arrived, all vendors started cutting unneeded capacity.Comment

There is 3300uf 6.3v are changed with 1500uf 2.5v caps
I think about using these caps from ali https://aliexpress.ru/item/4000998191222.htmlComment

Re: 3300uf 6.3V Poly recpaing
so what makes you think the caps have under 2v running through them?
can you find or take a high res pcb foto?Comment

Re: 3300uf 6.3V Poly recpaing
...because typically 3300uF caps were on the vcore output, and on an AM2 that will be under 2v...but yea, some pics would be good.
As a rule when polymodding, half the capacitance of the lytic to be replaced is a good standard to go by, been doing it for ages. I have never had a problem with it in well over 10 years. As a matter of fact, this post was created from a dual Socket-A that had all it's 3300uF caps replaced with 1800uF 6.3v Nichicon LG polymers. Its 100% solid.<--- Badcaps.net Founder

Re: 3300uf 6.3V Poly recpaing
little bit sad info but still, I'm thinking about using 3300uf 6.3v EPCOS B41851 caps instead of poly caps, as EPCOS are currently available in my local store... Poly are will arrive to me only in august. Also little off-topic, what is your opinion on EPCOS B41851 caps ? will be they good use here ?Comment

Re: 3300uf 6.3V Poly recpaing
run a mile - not made for 8 years!!!!
they arent low esr anyway - so wont work.Comment

Re: 3300uf 6.3V Poly recpaing
If those are your only choices, the CapXon LZ is equivalent to the original caps, but considering CapXon's past reliability, I wouldn't expect them to last longer than a few years.

Re: 3300uf 6.3V Poly recpaing
So, I found out that with needed capacitors is closed... My only choices are JB JRC and EPCOS right now... Damn... Shops in my region have little amount of good caps... Many of them are closed... Maybe I will start importing and selling good caps by my self...Comment

I've got a bunch of Poly VVX-250 VOIP phones that work fine as kind as long as they are plugged into the wall wart. Recently I got around to install a couple of TP-Link 5 port POE switches that are added to the existing plain Jane 24 port unmanaged switch. Great!!! Finally I am able to ditch the wall warts from these phones making more space on the desk, plus I am gaining some badly needed power outlets. So I thought.
Plugged in the first VVX-250 into the POE switch, booted up no problem. Plugged in the other Poly phones and they start to boot anywhere from 5 to 15 seconds,...11-25-2023, 10:46 AM -
I found these, i would only like to try them on a board to see if it post. It don't post at the moment, i guess there are 9 6.3v 3300uf that can be broken. Is these low or high esr? I did not find info on the web.

Hey guys, I have a question. I need to replace the caps on my og Xbox motherboard, but I can't buy quality capacitors in my country with this specification (everything is either out of stock, with a minimum order of 1000 or just plain too big to fit in the Xbox). Can I replace the 5 3300uF caps with 5 Panasonic 2700uF caps? Thanks -
Hello everyone,
I have a few busted Rubycons MBZ 3300uf 6.3v that are used for VRM purposes on a socket A motherboard. According to spec 12 mOhm with 2800 ripple.
I have used the search engine and it appears the Panasonics are the ones to get, but those are topics already years old and these electronic ultra low ESR caps aren't availably anymore
.
I can't seem to find any available caps on the known sites that are in spec of these Rubycons. Also i can't find Polymers with 3300uf or even close to that. Closest ones i found where 2000/2200uf ones but... -
Hi all,
For polymodding an original Xbox i'm looking for polymer replacements of the following capacitor:
2x 10v 3300uf Nichicon PW
One is on the left side of the board, the other one on the right as you can see the picture i linked below (the two big brown caps).
Could i just use 2200uf polymers to replace them or do i really need the capacitance?
I have searched the forum already but could not find an answer for it.
Thanks....
