Chemicon KZG in good condition

[coreAngel]

Bought a brand new cheap PCI VGA video card when Tigerdirect.com closed almost all of its retail stores.

It's intentioned for an old pentium 4 pc, its a EVGA GeForce 6200 , was happy until i saw Chemicon KZG's near the heatsink of the processor, which were all perfectly ok Manufacturing date of the card was mid 2004 so after 10-11 years sitting im worried about using it since kzg don't have the best reputation.

I decided to recap it using polymers, like these 2

any thought's, is this a good preventative recap, or have i lost my mind

e-VGA GeForce 6200? Please post a picture of your video card, if possible. e-VGA often liked to use other cheap, bad capacitor brands on their low-end video cards. In particular, beware of Sacon FZ! (see link below.) Those are by far the worst capacitors on the planet.

Anyways, those polymers you posted would likely work fine if all you have on your video card is 16V 470 uF Chemicon KZG. However, I still encourage you to post a picture so we can see if there are any other bad cap brands. Also, it may be possible to use 6.3 V or even 4 V polymers in some spots, since the RAM and GPU typically use less than 2.5V and ~1.2V respectively (but if this is your first time doing a recap like this, then probably best to replace all caps with same voltage and capacitance values... otherwise you can try something like this: http://www.mouser.com/ProductDetail/...EuNZf6ESVMc%3d)

Finally, once you get the video card fixed, use GPU-Z to see what GPU chip it uses. If it is a NV43 revision A or B, you will likely be able to soft-mod it to a 6600. Basically, that will give you 4 extra pixel shaders. If you use that video card for older games, you will notice a slight improvement in performance. If you don't game, then no need to bother with this mod.

No, not at all. There is nothing wrong with fixing some older hardware if you are going to use it. By getting rid of the bad cap brands, you know you can trust your video card to work.

However, I personally wouldn't invest polymer capacitors in that 6200, unless it has good cooling. The GeForce 6, 7, and 8 series all have the bumpgate problem, where the GPU die starts to separates from the GPU package when the GPU temperature goes over 60C. This usually happens with multiple ON-OFF cycles. So if you want that 6200 to last, make sure it runs cool (preferably under 55C). If it has a passive heatsink, put a fan on it or point one towards it. You can use GPU-Z or SpeedFan to check temperatures (though there is other software for that as well).

more pics i hope they are adequate

Yup, more than fine.

You have a e-VGA 512-P1-N402-LR. From what I gathered on the net, that is a NV44 GPU, so you cannot do the softmod. But that's not that important anyways.

As for the caps, I see some more options here. See the picture I uploaded.
https://www.badcaps.net/forum/attach...1&d=1443151972

The caps circled in red are likely for the GPU Vcore voltage. Are they 16V 470 uF KZG or something else? Reason I ask is because the caps circled in yellow below that (I will talk about them in a bit too) appear to be 1000 uF. So I wouldn't be surprised if these are 1000 uF caps as well.

If the caps circled in red are 1000 uF indeed, you can use these caps then:
http://www.mouser.com/ProductDetail/...wibyu1oIukI%3d
(and even if they are not 1000 uF, you can still use those caps).

As for the caps circled in yellow - those are likely for the RAM Vdd voltage. One of them has "1000 uF" written on it, so I assume both are (they appear to be connected on the other side of the board). In that case, you can use either these:
http://www.mouser.com/ProductDetail/...ZtbhzWMVL5A%3d
or these again (same as the ones for the GPU Vcore)
http://www.mouser.com/ProductDetail/...wibyu1oIukI%3d

Finally, there are the two 16V 470 uF caps I didn't circle with anything. Those likely filter either the 12V rail or 5V rail coming from the motherboard. Since I can't know for sure, it it is probably best to keep the capacitance and voltage specs the same here. You can use the caps you found... i.e. these:
http://www.mouser.com/Search/Product...47-RNE1C471MDN

And that should be it. If you put a fan on (or near) that heatsink, that video card will be bullet proof .

thanks for your help ( im still surprised the kzg's didn't blow up being a long time sealed)

To answer you questions all 4 caps GPU/Ram are all 6.3v 1000uf parts which im going to replace with those nichi polymers

then the lone ranger's 2 caps on the top are 16v 470uf parts, (even though i am cooling this card with a fan im still worried about using electrolytics so im going full polymer)
