I live in Tampa, FL and my mobo recently had the leaky caps problem and I can replace them myself because my uncle has had experience in electronics industry for a while. BTW, where do I buy the caps at? Some people are saying radioshack doesn't carry high quality caps?

EDIT:
HAHA. OK. I'm cheap. BTW, mouser.com has so many different type of 2200 microfarad 10v capacitors. High-temp, low-leakage, low impedance, etc. Which type do I get, can somebody please guide me?? I need 4 2200 microfarad, 10V. Need 5 1000 microfarad, 6.3V. I need 4 1500 microfarad, 6.3V.

So, you can solder because your uncle has experience in the electronics industry? :laugh:

You'll probably have to get them online.

..the bigger the blob..the better the job. I've heard of people changing cap's but it's tricky stuff. MOB's are multi layered and easily damaged. None of my bioStar boards caps have failed..so Ive never had to fiddle wit it. I've heard of people changing caps on video cards to improve certain performance aspects..luck good you to...:)

If I'm not mistaken, you don't need anything special. Low impedance, maybe, but doubtful. Get the cheap ones.

Physical damage, they generally won't function properly, either, to the point of detectability with a multimeter.

Well, first of all, your mobo becomes unstable and stuff. Then when you look at mobo, there is generally brown crusty stuff on top of the cap or around it that has leaked out. In my case it's both! Even if you see the smallest brown dot on top of your cap, it means it has leaked. It should be pure silver or whatever aluminum on top.

It's been a while, but from what I remember, most important thing is to match capacitance values (farads) and type (electrolytic, low ESR) Voltage you just need to make sure it's atleast the same or higher. However it's better to keep the rated voltage close since the higher the rating, the bigger the cap is physically.

I think panasonic was recommended for replacing mobo caps.

I heard some good things about Nichicon caps too, so I'm just going to order low impedance Nichicon caps off of mouser.com. Thanks for your help guys.

cant you just use some angle cutters and then solder the new ones to the posts where the old ones were soldered?

Look at the caps on a mobo. They're pretty much flush with the surface of the PCB.

You want good connections, so it really is best to de-solder the old ones and re-solder the new ones directly to the pads.

I suppose you could tug on them and see if the leads come out, then solder to the old "legs", but you risk cracking or breaking something pulling on the caps.

Anyone else remember the huge Abit/MSI cap fiasco? And the reason for all the leaky caps?

Hey, all I ment was that there are some half-assed computer "geeks" out there and in these forums. Some POSERS! You know? This kid in my assembley class the other day: prof asked him about his computer. The kid didn't even know the MHz! *smacks head* Seems like geeks nowadays don't even know what an IRQ is.

I was impressed to see that you're the real deal, back to basics, soldering some caps on some pcbs....



Soldering iron to your mf'kin mobo?!! *leans back, deep sigh of pride* You sir, are keeping it real.

put some duct-tape and super-glue on those bad boys and you'llb e up to speed in no time.

And if people these days can't identify IRQ 0... wow, they don't deserve to have one.
