My ECS P965T-A has spent nearly the whole time since I bought it new over 6 years ago running OS/2. It's installed multiboot, so there is some running time in Linux and DOS. Quite some time ago already, maybe around 3 years, I replaced a very large number of 8mm caps on it, but not its 3 purple 10mmX25mm OST RLX 1500uf 16v. I no longer recall details, but suspect I had some bulgers and replaced everything of same specs with suitable low ESR replacements I had on hand at the time. As I use it constantly, I wanted it back in service without waiting on ordering what I didn't have. Doing what I did got it going.
Since then I acquired some Rubycon MCZ 1500uF 16v 10mmX20mm from Topcat, so when it started fritzing today, and based on the OST reputation here, I decided to install them without even thinking about what other than dust accumulation and overheating could be wrong. On removal I checked and found all 3 OSTs measured above 1500uF, with highest ESR of the three .01. The Rubys I put in measured ESR as high as .02, and uF as low as 1472. The board still has some smaller OSTs (100uV 6.3v) and G-Luxons (470uF 16v & 100uF 16v). I put it back together with just the 3 new, but the corrupt video output was at least as bad, maybe worse. Turns out a near twin "new" PCIe X600 Radeon fixed it.
These 3 OSTs seem to be far better than their reputation here. Should I commit them to the trash anyway? Save them for use in power supplies? Other?
