Hoping someone can help me out.....I had a sheet with these values listed, but cant find it.

I removed some bad caps from my Ti4400 and am now (several months later) going to replace them, however I cant find the sheet that had the values on it.

Does anyone know the following capacitor uF / Temp / Voltage / etc for the following locations

C1286 - Top Right of Card about a third of the way in
C1287/1288 - Both are listed around this cap area. Its to the right of C1286
C1298/1299 - Both are listed around this cap area. Upper Right Corner. Would be the Upper Right most Capacitor
C1366/1258 - Both are listed around this cap area. Far Right side of card, a little past half way down. Would be the 5th Capacitor down if you count from the top

Thanks if anyone can help me out here!!

do you have any photos of what everything looked like before you removed the caps?

Install the card in your motherboard and turn on the PC. Go into the BIOS so that the PC doesn't boot into the operating system.

Take a multimeter and probe the voltage of each capacitor position you want to install a capacitor into. It should be either 3.3V, 5V, or 12V.

For the 12V positions you need to use a 16V rated polymer capacitor. 330uF or 470uF (or higher is adequate). For the 3.3V or 5V positions use 6.3V polymers at 680uF or higher.

Polymers are important, because the VRMs on these cards for this generation started to require ultra-low ESR series. You can't really get ultra-low ESR electrolytic caps anymore, so polymers are necessary. Just filter your search on any of the websites to the 'aluminum polymer' type, and you're looking for the radial leaded variety.
