Re: High Ripple Current and Low ESR

Thanks You guys, I have learned a lot in 3 days. Since damaging one of my capacitors and looking for a correct replacement, I had no clue how important they are in a computer. Or how they work, but it's great fun learning something useful, that can save you money or improve your stability while overclocking or building a rig using a old used motherboard.
Thanks for all the help!!..

Re: High Ripple Current and Low ESR



OK, I think I'm starting to catch on.
Lower ESR = Good
High Ripple is prefered,... and Series is Chip type or Lead type....

Hello, I have a question about Polymer Capacitors used in motherboards.
When comparing polymer capacitors datasheets, And all items listed are the same, except for the Ripple Current and Equivalent Series Resistance.
Are the capacitors with higher ripple current and lower ESR, better grade?
Example: Ripple Current 6A and ESR 5 mOhm
VS: Ripple Current 5A and ESR 8 mOhm
Which of the two polymer capacitors would be considered higher quality, or better grade?... And what does the (Series) refer to, does this need to match also or are there better series then...

Wow! this is a great site, You are all vary nice to noobs who are trying to learn or ask silly questions.
I will order the 6.3V ones on Monday, And Thanks for all the help.
as I was worried that finding the correct cap was not going to happen, and spent days scrolling through pages of caps not even knowing what I was looking for. Found it in short time here, and learned something.

Even though it seems they're 6.3v capacitors on the board, it really shouldn't see more than 2-3v.. so you could use 4v rated capacitors around the cpu area.
In this case, you could go for these:

Re: Asus P5E64 WS Evolution

Thanks Guys,
The markings on top of cap are: 8F.11, 560, 6.3V
The Digi-Key part number : 493-4043-1-ND, Nichicon, Looks like it will work.
I was asking about replacing all 11 caps, because they are all looped togather on that 8-phase power design around the socket, and I thought mixing one from a differant mfg. may cause issues?, and the motherboard is 4 years old and I do overclock it, so if I'm pulling board to replace one, may as well replace all 11 I guess it's only $20.00.
And yes I donot know why it did not short, or...

Re: Asus P5E64 WS Evolution

Hello everyone, I tried to edit my first post, but was not allowed? After reading all rules let me start over, Will I need to replace a dented or slightly crushed cap on my motherboard. The system seems to run just fine with dented cap. And if it needs to be replaced how do I order the correct cap?
the exact match is not on your listings, So do I replace all 11 on the 8-phase design around CPU socket or just the dented one?
The board is Asus P5E64 WS Evolution, I bought new in 2008, with Q9550 EO @ 3.4 GHZ, memory is 4X1GB Corsair Dominator...

Hello, I need all 11 capacitors, for the 8-phase power design around the CPU socket. they are Polymer, 560uf, 8f.11, 6.3V capacitors.
I damaged one in the top row trying to install a waterblock that was too large. And crushed the one on the left end top row. But system is working fine, the cap is creased were it's crushed but is not leaking. So I thought just replace all instead of just the one. any suggestions would be great, Thanks in advance.
