[AndreiRO]

I just saw this cap and i thing is a bit bulged ~1mm, is it failing?

My pc works ok

Dell GX260

Re: Is this a Failing CAP?

Yes, it's failing.

If you have others around, especially with datecodes from 2003-2004 you'll have to replace those also.

If you want some good capacitors and you don't usually fix electronics, since you're from Romania like me, I could mail you some at reasonable prices.

Re: Is this a Failing CAP?

Yes its bulging and will fail - luckily you have spotted it before it goes
causing more damage. Replace others of same make/series age.

Marius how much i would pay if go to eta2u or CITGROUP? To replace my cap

Re: Is this a Failing CAP?

I don't know.

They'll probably charge you even for opening it up, and most service companies don't use quality capacitors so the repair will only last a short while.

If you have a soldering iron, it's relatively easy to replace capacitors.

Again, you say only one capacitor, but I see especially in the last picture 2 other Nichicon HM capacitors which aren't bulging but may very well be weak.

Nichicon had some problems with this series of capacitors around 2003-2004 so if those capacitors have the datecode starting with 04 (it's a 4 digit code on them), it would be safer to replace those as well.

If you'd be willing to mail me the motherboard along with money for capacitors and shipping back to you, I'd do it for free, it doesn't take a lot of time and I don't mind soldering and the post office is 100m away from my apartment.

But we're talking here about around 15-20 RON for shipping back (if you don't come to visit me, because I'm in Cluj) and each replacement capacitor is about 1.5-3 RON)

It's basically the same prices as you'd find on http://ro.farnell.com but they'd charge you 20 ron to mail them to you, i'd send them for the same price + stamp costs, about 2-3 ron.

Re: Is this a Failing CAP?

Here are the rest of my CAPS.




AND THE REST of the CAP are with a "K" on top

Re: Is this a Failing CAP?

The blue and gold caps with a "K" are Rubycon. Rubycon is a real good cap manufacturer.

The green one with a "K" is Sanyo.

Please edit your post and remove the pictures, they load very slowly and they're very large

Here they are attached to the forum, so they load faster straight from the site .. click to view them large







Anyway, the ones with K are MBZ on them are Rubycon MBZ, shouldn't have to replace them, they're high quality.
The one with a sort of K but green, near the ram, is a Sanyo capacitor, again very good, shouldn't be a problem with those.

The ones with the top that looks like a T are Panasonic. They're also good brand.

A minor issue is the two blue ones with a T on top are only rated for 85c, so that makes me wonder if the board was already serviced and someone used those to repair the board. They may not be critical so they could be ok, but it just doesn't sound like Dell would use 85c rated capacitors on their boards.

The other capacitor with T on top is Panasonic FJ series, that one is a good series, nothing to say about it.

So yeah, you're good with everything except those Nichicon HM capacitors, you should replace the 3 by the cpu, the one by the ram and the one by the video card slot. Only the one by the video card slot is obviously bad or going bad, but the rest may also be bad only you don't see visual signs.

It's actually any date code from 2001 to 2004 (H01** to H04**) - that's for Nichicon HM and HN only. Their other series were not affected.

The Dell OptiPlex GX260 motherboards are quite old. I have one with bad Nichicon HM caps as well. The date code on those is 2001. All are bulging. So there are high chances that yours will fail too.

A minor issue is the two blue ones with a T on top are only rated for 85c, so that makes me wonder if the board was already serviced and someone used those to repair the board. They may not be critical so they could be ok, but it just doesn't sound like Dell would use 85c rated capacitors on their boards.

Mine has 85C Teapo and it has never been serviced so I think it's normal. Even my Dell GX270 motherboard has some 85C Nichicon caps. I'm not sure what Foxconn was thinking when they made these motherboards.

Re: Is this a Failing CAP?

Looks like a very old board, whether or not it's worth repairing is another story (there's probably a Celeron or an early Pentium 4 under that heat sink). Unfortunately we can't see the full date code as nearly every photo has the negative stripe closest to the camera, and the date code is closer to the positive side. I am going to say that going by the partial date code shown on the tops of those caps is either H0225 or H025_ (either June or December 2002).

I'm not sure what Foxconn was thinking when they made these motherboards.

They were thinking it would remain in a 22°C air conditioned office for 8 months and then be replaced.

My parents' Dimension 4550 is full of Nichicon VRs.

So is my lawnmower! (Yes, really. It has one on the "interlock module")

Anyway...

Erm...

Uhh...

Yeah, you'll want to replace that cap.
