Default Matsonic MS8308EP Bad Caps

Got 9 bad caps on this Matsonic socket A mobo before she decided not to post.

All caps are made by G-Luxon

gonna recap it?

not recommended to leave it until she fails to post, better to recap as soon as you see some bulging/leaking.

Looks like it's the same board as PC Chips M810LMR and ECS K7SEM. You're lucky that the mosfets are not burnt (or at least they look OK).

The FET's have been getting hot, look at the discoloration on the PCB. I hope that they are still ok. Hopefully it will be worth a recap. Good luck!

Yeh, the back is really discolored. If it worked, it will be worth $20 or w/e in caps!

based on my experience the m810lmr boards are not really worth recapping. socket A, int. everything, picky about video cards, unstable b/c of chipset heat issues. use the $20 to buy yourself an 8rda off ebay.

hmm Ill calculate the cost in caps and see if I cant just replace them with some used ones I have laying around. I will just be using the mobo for a folding rig anyway. Nothing workstation or anything of such.

okay, but make sure the used ones are of good brand and low ESR. btw I meant 8rda3 in my last post.

Yeh it was actually a customers that they brought to me after she wouldnt post.

The board is now mine and its just a crapper that as I mentioned Ill just be using it for folding. So, obviously I dont want to put much if any money into the damned thing. My question is, it had those shitty G-Luxon caps. They were rated at 2200uf 6.3v and there were 12 of those and 4 chokes. Thats honestly the most caps and chokes Ive ever seen for a cpu supply curcuit ever and this is a low end board! Would it be alright if I replaced them with 1500uf caps (low-esr of course) that I took off another board? This board will be at my house so I can watch it and it honestly doesnt even need to be 100% stable.

WOuld that be fine?

Inductors. They form a filter network with the lytic caps.

PCB layout is almost identical to PCCHIPS M810LR v8.0. / ECS K7SEM v3.0a / Amptron K7- 810LM Motherboard.

Sure! Just kind of an update too, Ive been running this mobo with the 1200mhz duron everyday 24/7 folding (100% cpu load), and it still is running rock solid!

As for the brand of caps, they were kinda mixed , just used what I had around since its just a folder mobo. They were samsung, choyo, and that other brown colored one (cant remember name) that comes with DFI mobos.....

I agree with willawake, the choyo caps are shit. They have been seen to fail many times here.

At least you know what to replace in case of unstability

HaHa,

I just found this thread and I have the same Matsonic (it is a 266) and was wondering if I could replace just the single 2200/6.3 that is swollen. There is no discoloration of the board @ the FET's which is a good sign I guess!

To see that this mobo works w/a vast assortment including 1500 is great news.

Due to the low value of this board (are all EP's 266's? is the 266 really worth much more?) I'm going to use parts removed from other mobos.

I have an Abit KT7E that has a few slightly bulged caps and I'm going to get new stuff for that one. However, I don't think I'm going to replace all the caps. Since the 2200's all look perfect. (All caps are Jackcons and there are 6 types: green w/gold "LOW E.S.R.", black w/gold "LOW E.S.R.", and black w/white.

Don't replace just the one - the other will go bad soon so you'll have to replace them later anyway. And there's a risk of the MOSFETs shorting on these boards with bad enough caps...
