asus p5ld2 w/ kzg

[iamspuzzum]

ok, little confused on suitible replacement for chemi-con 820uf 6.3v kzg (1.14 ripple, 0.36 impedance, "?" esr)

reading here that kzg's are lame, and there are betters.. but the esr, ripple, and impedance must be equivelant.

I have no idea which to replace with.

I'm sorry, but think I need spoonfeeding with this one :p


any help greatly appreciated

Don't just replace the bulging cap/s. replace ALL Chemi-Con KZG on the motherboard.

Re: asus p5ld2 w/ kzg

there are a lot of different types that you can use to replace them. for example, if using rubycon brands, you could use mbz or mcz serieses, and the same would go with other brands. Those are just the most common 2 types for rubycon's but for each brand, there are multiple types that would work. mainly try to stay with low esr or ultra low esr caps. as long as they are low esr and a good name brand and type, then you should be fine.

Not necessarily. Panny FC for example are considered to be low ESR, but their ESR is not quite low enough to replace KZG.

Re: asus p5ld2 w/ kzg

Sorry to revive such an old thread, but I haven't found anything else on the web about bad caps on an ASUS P5LD2 board. I also have this board, and have a few bulging caps. I am guessing that this is why my board fails to give post or any audible errors. After some testing, it appears that all my other hardware is working properly. The caps that I see with convex surfaces are labeled KZG 6.3V 1500UF. They are different from the ones that user iamspuzzum is referring to, but are the same brand and I see that you guys have seen problems with these KZG's before. I have NO PROBLEM in replacing all these potential trouble makers, I just need some assistance in choosing the correct ones to purchase.

Here are a few pictures so you guys can identify my possibly bad caps.. Sorry for my lack of knowledge on this subject. :/

I already see that you suggest I replace the little ones with these:

But I still need to replace the two different larger ones (1000uf, and 1500uf). Suggestions?

Re: asus p5ld2 w/ kzg

The ones in your first picture do not look like KZG

Possibly they are Panasonic FJ - to confirm, look for FJ or CFJ on their sides, together with a stylised M for Matsushita (= Panasonic)

If they are Panasonic, replacement probably unnecessary

and
https://www.badcaps.net/store/produc...products_id=38 (Yes, 16V in this case as the original KZG is taller than the standard for that size. Voltage is a limit, so you are fine replacing 6.3V with 16V).

The proposed replacement will be fine for the small 820uF capacitors. However, those do look like Panasonic, and it would be unusual for those to fail. Could you possibly get another photo from a different angle, or see what other markings you can see on them? Panasonic's logo is an "M" in a square-ish box. (Matsushita is the parent company of Panasonic.) If they are indeed Panasonic, and they have failed, you may want to check your power supply and case ventilation.

Re: asus p5ld2 w/ kzg

For KZG use Nichicon HM, Rubycon MBZ, or Samxon GD.

Re: asus p5ld2 w/ kzg

watch out for ost(blue) lytics under the hsf.
replace with sanyo sepc 560@4 from the badcaps store.
if it comes back to life after replacing the kzg's its a good upgrade.

Re: asus p5ld2 w/ kzg

or Sanyo/Suncon WG
or Panasonic FJ, FL

They won't fit. The KZGs are 8mm, the 16v Rubies are 10mm diameter. Use https://www.badcaps.net/store/produc...products_id=39

I recommend the user with the bad caps double check the sizes. They do look like 8mm today, both the 1000uF and the 1500uF. They really looked like 10mm last night. Maybe I should be more careful what I post on very little sleep.

Re: asus p5ld2 w/ kzg

pfrcom: Yes, the little ones are in fact Panasonic FJ. I see the little FJ on the side and the stylish "M". Since they are not bulging, and are Panasonic's, I suppose I wont replace them. I do want to replace the 1500uf KZG's though since they are bubbly on the top.

kc8adu: I don't have any blue caps near the HS/F area.

c_hegge: Thanks for clarifying. I will be purchasing the following item to replace my 1500 KZG's once you guys verify the diameter...
https://www.badcaps.net/store/produc...products_id=39

I hope this new photo helps in determining the size. Unfortunately, I don't have a micrometer to be certain. I used a .45 round in one picture, and a dime in the other. I sure hope that helps. The angle's are a little off because I was trying to get as much light in there as possible.

Since I'm already going to spend $5 on shipping, should I just order something to replace the 1000uf KZG's as well? Since you fellas say that KZG's are bad, I might as well, right?

Re: asus p5ld2 w/ kzg

The 45 is .45 inches or 11.4mm... So, the 1500s definitely look like 8mm, making this the correct replacement:
https://www.badcaps.net/store/produc...products_id=39

The 1000uF capacitors look to be the same diameter. If they are, then use these as replacements:
https://www.badcaps.net/store/produc...products_id=45

It looks like you have more Panasonic caps near the CPU socket where the blue OSTs usually are. That's a good thing.

Sorry for the erroneous advice last night. I've been sick with the flu, so I'm not on top of things as much as usual.

Re: asus p5ld2 w/ kzg

Dude, ABSOLUTELY NO need to apologize! I had a nasty flu for almost a month so I know what it's like.

If everyone else seems to agree, I will be ordering the caps that yyonline has mentioned. I value everyone's opinion very much and I really appreciate the help. I just want your blessings before I pull the trigger.

Re: asus p5ld2 w/ kzg

A big thanks to everyone who helped me out. I'll drop a comment if these new caps fix my board. Thanks!

Re: asus p5ld2 w/ kzg

Hello all, I hope it's ok that I jump in this old thread because this has my exact motherboard with pics already and I don't have a camera.
My question is about the 1500uF caps, I don't know which ones to get to replace them with. Looking in the store here I found the 1000uF and 470uF that I need but nothing match's the 1500's. The 1500's are 8x20, 6.3v, KZG's just like the one's shown above in the 5th post and the 3rd picture.
Any help would be greatly appreciated and I plan on ordering here when I find the correct one's, Thanks!!

Re: asus p5ld2 w/ kzg

These will work:

Nichicon HZ 1500uF 6.3v 8x20
http://search.digikey.com/us/en/prod...PM6-ND/2428107

Nichicon HM 1500uF 6.3v 8x20
http://search.digikey.com/us/en/prod...PD6-ND/2428126

Panasonic FR 1500uF 6.3v or 10v 8x20 (same capacitor, same ratings, same size)
http://search.digikey.com/us/en/prod...363-ND/2433497
http://search.digikey.com/us/en/prod...379-ND/2433513

HZ > HM > FR
FR is technically a bit worse than KZG but it's so close it's within the margin error... we're talking 0.026 ohm on KZG versus 0.030 on FR, so imho it's insignifiant. If the caps are swollen their impedance is surely way outside the value yet the board worked for a long time like this, so a few thousands of an ohm won't matter.
On the other hand, the FR's are rated for 9000 hours at 105c, compared to much less on the HZ and HM (about 2000 hours) so they would be great ones if the design of the case is bad and the system is known for heat.

Re: asus p5ld2 w/ kzg

Thank you very much for your help. Now that I know what I need i'll put my order in and hopefully be back up and running soon. Thanks again!!
