Recapping Asus EN8600GT SILENT/HTDP/512M

[Mezanine]

Hello everyone.
I'm trying to find good replacement caps to this graphic card, but I need some help in choosing what to buy and where to buy, as I am rather limited here in Europe. Most stores only sell in bulk. I'll need 820uF 6.3V, which I found Rubycon 6.3ZLH820M8X11.5; 330uF 6.3V, which I found Panasonic EEUFM0J331 Low ESR; 100uF 16V, which I found Panasonic M Series and I'll also need the ones shown on the photo, that I can't just find anywhere. I suspect they are 270uF 16V polymer capacitors.

Is this right? Where Can I find replacements? Are my other choices any good?

Needless to say this cards runs at very hight temps because of the poor design heatsink without fan and I think it was heat that messed the caps. Not all are visibly damaged, but I just want to replace them all and buy an active cooler for the card. I'm having all this trouble because I need the SVideo-out and nowadays that's impossible to find on the newer cards. This is my secondary card that is used only for the Svideo and Physix.

Thank you in advance

Those are solid polymer caps on the picture and those rarely go bad, are you sure the capacitors are the problem? What symptoms does the card give you?

Re: Recapping Asus EN8600GT SILENT/HTDP/512M

There are 3 solid polymer caps on my card. None of them seem broken, or leaking. The ones that have problems are the 820uF 6.3V. Some of them are bloated and 2 are really popped.
I just thought it would be better to replace them all, but I guess I can only replace these. Regarding symptoms, there are some transparent squares appearing randomly and changing colors like pink, blue; but only when I enter windows. During boot up the screen appears ok. These symptoms appeared after those 2 caps popped.

What do you think of the replacement caps I found?

Thank you

You need to provide the original capacitors brand and series markings and clear focused pics so I can compare them with the replacements.

The red circles show where some of the damage caps were. These were Panasonic [M] FJS 6.3V 820UF. I already removed them. Yellow circle is a 100uF 16v 105º with the marking 79 III NV and the green circles are Rubycon 6.3v 330uF ZL series. The yellow and green don't seem damaged, at least visually. THe 3 polymer caps don't seem damaged either.

Looks like the polymers are fine. The bulged ones are electrolytic caps and look like they're Rubycon. Likely, high temps was the cause of failing.

Re: Recapping Asus EN8600GT SILENT/HTDP/512M

Those rubycon ZL's should be good enough but I would go for panasonic FM 820uf 6.3v. Slightly lower impedance and slightly higher ripple current. Both should work just fine.
The other caps on the card should be fine. I would mount some kind of fan on that heatsink, or buy a heatsink with fan... heat is probably the cause for those bad caps.

Re: Recapping Asus EN8600GT SILENT/HTDP/512M

First of all I'd like to thank both of you. Like I suspected it really must have been temp. If I'm able to fix the card by replacing the caps, I will the change the cooling solution for sure.

Just to make it clear for me the original caps are:
Red circles (damaged, already removed 11 pieces) Panasonic FJS 6.3V 820UF
Green circles: Rubycon 6.3v 330uF ZL series
Yellow circle: 100uF 16v 105º with the marking 79 III NV

As far as you see are the green and yellow circles bulged and also needed to replace, or it's just best to replace them no matter what?

To replace the red circles I just found Rubycon 6.3ZLH820M8X11.5. (ZLH series, not ZL). All the panasonic I find in Europe to buy are 820UF 10V FR series. Are these any better than the Rubycon ZLH?

If you want to keep that card running, change the cooler.
If I can bring it back to life I'm considering this:

Re: Recapping Asus EN8600GT SILENT/HTDP/512M

ZL and ZLH are almost the same specs so both should be fine. I can't really see if those caps are bulged from that picture but you could replace them too just to be sure. The polymer capacitors should not need replacement.
You can replace the 330uf 6.3 zl caps with 330uf 10v zlh caps.
I can't identify the 100uf but a zlh 100uf 16v or panasonic fr 100uf 10v will be fine for that.
Panasonic FR are more or less the same as rubycon zlh/zl so those are adequate too.

Re: Recapping Asus EN8600GT SILENT/HTDP/512M

Thank you very much. I'll buy the caps and post the results in a few days.

I'm glad I was able to help. Can't wait to hear how you did.

Farnell has a Portuguese version of their site so they should be able to ship to you.

They have Rubycon ZLH, Panasonic FM and FR series:

ZLH 820uF 6.3v 8x11.5 945mA 0.056 8000h@105c http://pt.farnell.com/rubycon/6-3zlh...-3v/dp/1712577
FM 820uF 6.3v 8x15 1240mA 0.041 3000h@105c http://pt.farnell.com/panasonic/eeuf...0uf/dp/1855210

FR 820uF 6.3v 8x11.5 950mA 0.056 6000h@105c http://pt.farnell.com/panasonic/eeuf...0uf/dp/1800604

Looks like ZLH are the winner... if you plan to change the heatsink later, you might as well get FM as they have better specs but make sure 15mm will fit there.

Re: Recapping Asus EN8600GT SILENT/HTDP/512M

Thank you mariushm, but since 2009 Farnell doesn't sell to private customers in Portugal. Just for companies. If Farnell shipped to private customers in Portugal, there weren't any problems in finding caps over here. Our local dealers that could buy from Farnell, don't do it.. they don't have any good caps. Just "standard" low quallity ones. I'm gonna have to order the ZLH from the UK. The FM I can't find online anywhere in Europe. From the US there's the postage problem... too expensive and could have to pay more if held in customs.

Re: Recapping Asus EN8600GT SILENT/HTDP/512M

That sucks... I use the .ro version a lot and they ship fast and cheap.

If you can't find something good or the shipping is too expensive and you can use Paypal to send a few dollars I'm willing to mail you some.

I have here some Nichicon HN 820uF 6.3v 8x11.5 1300mA 0.021ohm and I can give them to you for the price I paid for them, about 50 us cents each.
There's also some 820uF 35v Panasonic FR which would work but they're 10mm wide and 25 mm tall .. i bought these for 60 us cents each.
Add 2-3$ for shipping and stamps.... and it should reach you in about 4-6 days.

I helped other members on this forum including Koda so he can vouch for me, not trying to scam anyone.

Re: Recapping Asus EN8600GT SILENT/HTDP/512M

Would those Nichicon perform better than the ZLH or the FM? The maximum component height on that area, according to the new heatsink specs is 18mm.
Since I'm recaping all the 11 820uF 6.3V, I'm going to recap everything except the polymer ones. There are 2 330uF 6.3v Rubycon ZL which I'm replacing with Panasonic EEUFM0J331 Low ESR and 1 100uF 16v 105º with the marking 79 III NV that I still haven't found a proper replacement.
Do you have them too?

[mariushm]

Re: Recapping Asus EN8600GT SILENT/HTDP/512M

Based on the specs, yes.

The ripple value must be equal or higher than the old capacitor's value.
The impedance value must be equal or lower than the old capacitor's value.
You can put capacitors rated for higher voltage instead of lower rated ones

This HN series is "ultra low impedance/esr" designed for motherboards: https://cdn.badcaps-static.com/pdfs/...69df1e6a59.pdf
... so it's 100% perfect for video cards. Rubycon ZLH and Panasonic FM/FR are just "low impedance"... but really, for the purpose these capacitors are used on the video card, all the series mentioned would work great.

If you do want to get them from me, I have 330uF 35v Panasonic FM (10mm x 16mm) or 330uF 10v Nichicon HC (8mmx11.5mm) ... the later don't have the specs as good as the ZL but it's close enough I wouldn't worry about.
Both series were about 45 cents a piece when I got them a month or so ago.

The 100uF one.. I don't know the brand based on what you say... but I have 100uF 16v Panasonic FR ... so you won't have to order a few separately.

Re: Recapping Asus EN8600GT SILENT/HTDP/512M

How much for 11x Nichicon HN 820uF 6.3v, 2x 330uF 10v Nichicon HC, 1x 100uF 16v Panasonic FR with postage to Portugal included?

Just write him a private message for details about a deal, if he is not subscribed to this thread he might not read this last post you made and btw yes I can vouch for mariushm.
