Graphic Cards HELP: Replacing Blown Capacitors on XFX 8600GT 256DDR3 and Mercury 945GCM

Thank you guys. Allrounder, thanks for the link however I still can't find what the "A" stands for.

Great! I can now post photos! You can see the lower two 6.3V caps have blown and I have troubles in interpreting what the black ones' voltages are. The number in the middle should be uF.

Yes you are right about the black ones. "A" is just some sort of representation.

Top one is some model/part number.

Middle one is the value in micro farads.

Bottom one is the voltage.

Same is true about the blue ones.
 
Thank you very much ontherocks, I can finally have some peace of mind and start looking for caps on the web. So the black ones are all 16V, with 100 and 470uF? Great!

Just one more newbie question: I always have to match the exact voltage right? However, if I want them last longer I should buy larger farads caps, is that correct?
Everyone's, thank you for your kind help and have a great afternoon, it's 17C(63F) cloudy in Vancouver today. :)

No, it's the other way around.

The value of capacitor (farads) has to be identical, never fiddle with that!

The voltage could be different, but it has to be always greater than or equal to the original. If you want the capacitors to withstand longer, its better to purchase larger voltage ones (of course at a higher cost and size). Why is size a matter of concern? Because you may not have enough space in your current PCB to put in a larger sized capacitor.
 
Thank you so much ontherocks(and everyone too) :D, you save my day. I was totally confused with how to repair the caps.

Thank you and have a fresh morning.
