Recapping an MSI M5-7125

[Deft]

Hi guys. I have a Socket 939 MSI-MS-7125 that a relative gave me because his PC would randomly lockup/shutdown. He started to replace the caps but stopped because he didn't have all the ones he needed. Luckily for me he just upgraded to a new board before he found this site


Since this is going to be my first board recap so I want to make sure that I'm getting the right caps..

I'm not exactly sure what was originally on the board when he had it but this is what I found on the board:



100uF 25v: (4 KZE) - TOTAL (4)
470uF 6.3v: (2 KMG) - TOTAL (2)
470uF 10v: (9 KZE) + (1 KMG) - TOTAL (10)
470uF 16v: (1 KZG) - TOTAL (1)
680uF 10v: (2 Nichicon HM(M)) - TOTAL (2)
1000uF 6.3v: (9 Rubycon MBZ) - TOTAL (9)
100uF 16v: (1 KMG) - TOTAL (1)
1500uF 16v: (4 KZG) - TOTAL (4)
1800uF 6.3v: (1 KZJ -burst) - TOTAL (1)
3300uF 6.3v: (4 Rubycon MBZ (these are new caps I think)) + (1 KZG -burst) - TOTAL (5)

I Want to Replace
1 x 470uF 16v KZG
2 x 680uF 10v Nichicon HM
4 x 1500uF 16v KZG
1 x 1800uF 6.3v KZJ
1 x 3300uF 6.3v KZG

This is what I ordered:
1 x 470uF 16v 8mm MBZ Series
2 x 680uF 16v 8mm ZL Series
4 x 1500uF 16v 10mm MCZ Series
1 x 1800uF 6.3v 10mm MCZ Series
1 x 3300uF 6.3v 10mm MBZ Series

What do you guys think? If I replace those caps do you think I can get that board working properly again?

P.S. Thanks Topcat for creating badcaps.net which has now given me a new hobby for this upcoming winter

btw can a mod edit my topic so it says MS-7125 and not M5-7125. Thank you.

Those should be fine, although you may not need to replace the Nichicons if the date code is newer than 2005. The date code is usually something like H0328 (Year 2003, Week 28)

Thanks for your help. I think the date on the Nichicons was 0423 but I'd have to walk to the garage to be sure.

Hopefully after I get this board working again I can fix a 19" WS LCD monitor I had that just stopped working all of a sudden after about 8 months of use (got it cheap at Walmart). I'll have to start a thread on that project when I get around to it.

0423 = Year 2004 = Defective

Actually not all of them are defective
It's of course easiest to assume them bad but infact it was said by someone that it was probably only one production line that used the faulty electrolytic formula (overfilling)
Unfortunately there is no way to see any difference on these caps

Re: Recapping an MSI M5-7125

Assuming they are all bad seems like the safest bet unless we know which batch/production line each cap came from and which batch/production line the known bad caps are from :/

Sadly, that saying about one bad apple ruining the entire bunch seems to apply for bad capacitors too.

That's true. Because if one cap fails the others have to take higher ripple current, so it's only a matter of time till they all go bad.
