Bad news, it looks like my Soyo SY-K7VTA-B finally has a bad cap!

It looks like the Wendell 1500 uF cap next to the ATX power connector clip is bulging!

But, they were doing fine for at least 6 years.


Most of the cap brands that made it on the bad cap list wouldn't last this long.

But, my Soyo SY-K7VTA-B has been through unstable power, because where I used to be, blackouts and brownouts were common, because of the diesel generator they had.

Also, it used to be hooked to a power supply that wasn't doing very good.

Until sometime in 2002, it used to be hooked to a Deer 250W power supply and the PCB of the Deer 250W power supply under some resistors was darkened.

It looked like only one cap was bulging. That was in a spot that's most likely to have a failing cap.

I will post a picture tomorrow or shortly after.

Yes it will be good to see a photo. However the age of your board places it right in the worst period for bad caps. 6 years would be good if it is a server working 24/7. Remember cap life is dependent on operating hours and hastened by high temperature.

An intermittent AC power source is unlikely to have any affect on this part. If one cap has gone replace all similar caps and any that are known bad cap branded.

If the power supply is the same age check this out too and replace the caps. Usually the large input caps of a PSU are less likely to need replacing.

From June, 2001 to July, 2002, the motherboard was powered by a Deer 250W, which developed darkened areas where there appear to be resistors.

In July, 2002, I replaced the Deer 250W PSU with a Powmax 300W PSU, which I stopped using in 2003, because it kept on squealing. LOL.

It was by accident that I noticed spots that looked darkened in the Deer 250W.
