Re: Dell OptiPlex GX270 - multiple bad cap failures

Hi again, PCBONEZ.

Yeah, as this is mostly way over my head, I'm just going to stick with the voltage - and capacitance for that matter - of the caps I'm getting replaced: 6.3v and 1500uF. I think if I tried to get clever with these values it'd just end in tears. So, the replacement Nichicons I'm going for are [URL=http://uk.farnell.com/nichicon/plg0j152mdo1/capacitor-1500uf-6-3v/dp/1580599]these[/URL]. I presume these won't be affected by the date code threshold of 2005?!

Whoa there!

Toasty, I think you've misread my last post because there's no hostility to you or anyone else on my part. Maybe I've been unclear in what I've written and if so, I apologise for what seems like a misunderstanding.

From reading it, I'm just not sure which bit could be misconstrued as a dig at you.


If it's to do with the above line, the second sentence goes on to comment on the reliability of the price gap, not your advice. Advice that I appreciate greatly....

Re: Dell OptiPlex GX270 - multiple bad cap failures

They've got HN(M) printed on the side of them so what that means I'm not quite sure; hedging their bets and not admitting they're either, I dunno.

From your advice and the choices others have made I think I'll go with Nichicons. Though it's probably not a wise thing to rely on, the Nichicons are three times the price of the Panasonics; I wonder if the difference is indicative of superior performance on the part of Nichicons?

I'd originally been looking for the Rubycons but I can't find a supplier...

Hi, PCBONEZ

Just back to this after a few weeks of being away and then preoccupied with another crisis...

What you've posted up there really is way beyond my meagre understanding. Not for your want of trying but I still really haven't a notion; am I still miles off with the conclusion that first, find the best series and then go for the biggest can size.... Ah! mwah! bwaaah! gaaaaaaaaah!... my brain has just dribbled out through both my ears. *runs for mop and bucket*

Could you...

Re: Dell OptiPlex GX270 - multiple bad cap failures

This might be the classic newb seeing something complicated where it's obviously simple to those that know, but is [i]can size[/i] an electronics term or does it literally just mean the size of the coke can shaped body of a cap?

But if I've understood you right does that mean this [URL=http://uk.farnell.com/nichicon/plg0j152mdo1/capacitor-1500uf-6-3v/dp/1580599]Nichicon[/URL] cap that seems to fit the specs wouldn't be as good as one of the Panasonics as its can size is 10x13 - just like the Nichicons on my board...

Re: Dell OptiPlex GX270 - multiple bad cap failures

Not great to be replying to myself but I've come across Panasonic's [URL=http://uk.rs-online.com/web/search/searchBrowseAction.html?method=getProduct&R=4490851]FC[/URL] and [URL=http://uk.rs-online.com/web/search/searchBrowseAction.html?method=getProduct&R=5260976#header]FM[/URL] capacitors - mentioned in FAQ - at RS Components. Apparently, FM are the better of the two.

How does the Panasonic range stack up against Rubycon's MBZ and MCZ caps that I've heard so much about?Re: Dell OptiPlex GX270 - multiple

Re: Dell OptiPlex GX270 - multiple bad cap failures

PCBONEZ, have you heard of any firms that supply the Rubycon MBZ or MCZ caps in the UK or Ireland? It's just that I'm over here and it'd probably be cheaper and quicker to source these at home rather than from the US.

Re: Dell OptiPlex GX270 - multiple bad cap failures

Hi, I've been reading through this thread and it's been really enlightening as I'm trying to get my GX270 motherboard recapped.

Going by what I've learnt in this thread there appear to be just 5 Nichicon capacitors on my board and they're the ones that have swollen.

[As a bit of background, my Optiplex developed a problem over a year ago. One day it just didn't boot up so I switched it off and on again and it worked. In a strange way it was probably a bad thing that I got it to work this way as I...
