GeForce 6800GT recap, need help identifying caps and finding replacements

[fl0w]

Hi,

I just noticed that my Asus V9999GT (GeForce 6800 GT) had some swelling capacitors. I managed to identify the brown ones, which are Nippon Chemi-Con KZG series, 6.3V 820µF, which I plan to replace with this.
But for the yellow ones, I guess these are Fujitsu caps, without being able to identify which series... A picture of the video card is attached to the topic.

I need to replace:

• 2x 2.5V 1500µF => I plan to use this
• 2x 16V 330µF=> I plan to use this
• 1x 6.3V 680µF=> I plan to use this

Am I correct with the cap choices?

Thanks for your help.

polymers are a good choice - make sure the diameters are the same or the lead pitch wont match

Hi, thanks for your reply. Diameters are identical, I'm just worried about differences in ESR values, and I'm unable to find the ESR values on the caps. I only found that the KZG are low ESR, without any additional information.

on gpu's low esr is essential because of the frequencies they run the psu section at.

So the caps I mentioned should be correct?

They look fine but there is probably no point in replacing those Fujitsu caps: they are good quality...
And when replacing the UCC KZG caps I would go for a same-same replacement (same capacitance).

Alright, I will order this reference then. Thank you Per Hansson. The Fujitsu are not swelling so I won't replace these ones.
