Help sourcing capacitors

[happytechie]

Hi all,

I'm looking for some capacitors (in the UK) to replace the following on an Epox 8RDA+

2200uF 10v
1500uF 6.3v
1000uF 6.3 volt

I even have some pictures:




thanks in advance

if the place is maplins or farnells please can you let me know what product codes I need

cheers

Any that are bulging or leaking should be replaced. bulging ones can explode! leaky ones can leak all over the mobo and possibly damage it by adding capacitance between traces which shouldnt have any..

I have a few. How many of each do you need?
Note that for the ones that leaked, it would be good to use a higher voltage rating, as this might be why they leaked in the first place.
the ones I have are from dead mobos, but the caps are perfect.

I think rapidelectronics.co.uk would also sell the right ones, maplin might but they probably more expensive.

I have:
24x 1500uF 6.3v (8 x luxon, 16 x teapot)
2x 1000uf 10v (luxon) 3x 1000uF 10v (rubycon)
I have some 2200uF but the voltage rating is too low.

http://www.rapidelectronics.co.uk/rk...2556&XPAGENO=1
for 1000uf and 2200uf. Get 16v versions.

Incase you dont know, you need to make sure you solder them the right way round or they will explode/leak etc... they have a line to indicate negative pin on them..

RS Components are another good source.

I'm a little worried that Epox still have this problem though

[SilentDeath]

With higher rated capacitors there should not be this problem. Its possible that all of that board version have this problem, or it might have just been a bad batch... asus and abit have also had this before with some of there boards

Ive been asked for 14 x 1500 6.3v caps from someone else. Tell me if you want them, if not ill give them to the other persoon with same problem.

Hi Silent Death,

thanks for all the replies

I will take any of the above mentioned caps off your hands, let me know how much you want and we can sort delivery / paying etc out. paul<underscore> taylor12345<AT>msn<dot>com if you want to go that way.

In total I need:

4* 220010v
5* 1500 6.3v
9* 1000 6.3v

I guess higher voltages don't matter

It is the 2200 and 1500 pico farad caps that have the worst bulges / leakage so those are the most pressing. I was shocked to find then at nearly 50p each in maplins, at that price it will be cheaper to get a new motherboard.

Epox are being silly and trying to tell me that there in no known fault with the capacitors on the motherboard and I must have had a faulty PSU and overly hot case! This will be my (and the company I work fors) last adventure with Epox products!

not sure if they sell them for that voltage, i remember a mate picking up some from maplins shop - for 1p each

www.maplin.co.uk look for your nearest

I cant find anywhere with 1500uF at any voltage, but the rest are resonably cheap. You should be able to replace the 1500uF's with 2200's or 1200's as they are not used for timing, only storage.

If your board is within the warrenty then I would just send it back. To make the caps leak they need to be either REALLY hot (105c for most or 85c for some) or over-volted.
Capacitors themselves dont make much heat atall, so if they are hot that is due to bad board design. Usually from them using the mobo is a heatsink for the mosfets which can get very hot.

I think its probably best to buy new capacitors unless your good at soldering?
these ones are from old mobos and so the leads are very short, it might be difficult to get them soldered on esp if the capacitors are not the same diameter.

You can have them for £3 to cover the cost of postage

Wow... you mean to tell me that people actualy would rather replace them, instead of buying a new mobo! Thats too much work... And how did you damage them? I never had that problem...

[Big RICHARD]

IIRC there were a bunch of dodgy capacitors going round a while ago that found their way on to some motherboards. Someone had stolen the 'recipe' for the electrolyte, but only got part of it and tried to make the rest of it up, meaning that some very poor quality capacitors were produced that exploded and leaked!

Thanks for that sah,

If they are reclaimed then I will pick up some new ones, thanks for the offer.

myth, I am more than competent with an iron and can't see any dificuty with a new cap on a mobo. The legs are actually spaced out quite well due to the phisical size of the caps.
A new mobo would be £4oish for a good nforce 2 board? versus perhaps £10 for all the new caps and a few hours of my time no contest tbh, anyway if I was buying a new mobo it would be a nforce 3 one and then I'd need a new CPU and some new memory as well

Big Richard, I think you are right but I'm not sure if that is an urban myth or a genuine fact. For info all the dead caps are branded ECS and all the good caps are branded sanyo.

Thanks for your help all,

What I posted actually happened. Whether it is the case here or not is a different matter
