Help with identifing Caps from a 8800GTS Video card.

[eclypse]

Hello,

I just bought a damaged EVGA 8800GTS 320MB Super Clocked card from someone online. All the silver caps were broken off apon other things that were damaged in shipping in the past.

Anyways i need to know what these aluminum caps with a plastic base are called and were i could buy some replacements?

The guy told me the numbers off the top of the caps.

From top to bottom:

648
SVP
180
16

Ofcourse i have no idea what any of the numbers mean..

Please help me out.. i'm hoping i can repair the card and give it to my Godson for Christmas.

repair with those.
these caps are of better quality.

These are 16 volts, 270uf and great low esr rating

Ok thanks.. So it dont matter that these dont have the black plastic base as the originals did?

So whats the other markings on the caps? Specifically the 648?

So 180 is the uf rating and 16 is the voltage.

Is there anywhere in the states to get these caps?

[Boogerlad]

sorry, correction, you need surface mount capacitors. i can't help you there. More uf is okay, but you need to find the surface mount version, or you could mod it and put some holes through to accepts standard non surfactmount capacitors. i'm not sure if you can get it in the states though, i'm in canada

I could just bend the leads and solder it on..

You could talk to the site owner of www.badcaps.net

Topcat, I think he can sell you Solid polymer caps, (brand Rubycon or Samxon)

If he can't I'm pretty sure a guy on the forums there can, Samxon has a new series of solid polymer caps released, I think those would work good...
His forum name is Big Pope

Thank you very much! I'll try getting ahold of him soon.

mouser.com sells surface mount, they might have what you need. But before I'd spend any money on caps I'd do a full inspection of the card and then solder the broken caps back on with short wires -- to run a test only, that card looks pretty abused.

The black plastic thingy is the buzzer that screams if the 6pin power plug is not plugged in, you don't need to replace it.

Thanks, i'll have a look. Though i was already told to not try getting the same surface caps as you need special tools to reattach them.. A regular solder iron will damage them. I was told to use regular caps.

The card was trashed in shipping when the original owner sold it to someone overseas.

Heres where the real trouble lies in the tear in the PCB where this chip was tore up. I hope to figure out how to fix this. I should check this area out first before i order the caps.

Cant wait to get the card in the mail to desolder that part and have a closer look at that tear.. If anyone has any info on how to fix a tear in the PCB i'm all ears heh.

Topcat said he dont have any :( havent heard back from Big Pope, though he's overseas.. dont want to wait that long.

Might have to go with mouser.. scared to though.. Cause the 1 and only time i ordered something from them a year ago it was lost in the mail for a week till luckly they found it. And yes it was around this time of the year with that awesome rookie holiday help. Good old USPS!

You catch me!:D i am in Hong Kong.

Holy cow batman, the card is coming in today as it hit my local post office today! God i cant wait to see it.

Sucks that today the family is headin out to the Circus :( Damnit man..

What tools do i need to solder on a surface mount cap? A good heatgun? ALl the heatguns i see come with a 10x10mm 4 sided tip.. It would fit but theres only 2 solder spots on the cap.. Does that matter or do i need a tip that has 2 sides? I also have seen a pair of hot tweezers. Would that work ok as well?

So if i go with a heatgun i'll need solder paste as well right? Which kind? 200c Heatgun be fine?

Or do i just go with a regular cap and try to make it look as clean as possable using a regular soldering iron?

Looks like i was sold a card that is not possable to fix.. i asked for pics of the memory chpis and that northbridge looking chip and if they had any damage cause they were all covered up with thermo paste and pads.

The seller (sabregen) uploaded 4 pics showing the chips.. ofcourse the pic with the northbridge looking chip was blurry and had some thermo residue on it so i really could'nt tell.. So since he didnt comment on the damage i figured he ment they were all good.

So i get the card today around 2PM.. All excited i open it up and pull the card out and look right at the chips and see some more chips that are nicked up that was'nt mentioned.. Ok so there may be a chance there still funtional.. Check the broken chip with the torn PCB under it and who knows if thats fixable.. I'll have to ask. Though once i look at that northbridge looking chip i see a chipped edge! Looks pretty major and toast to me! No chance for repair not reason to keep on debating about what caps to get and tools to buy to attempt a repair as that chipped chip kills the deal.

Check the pics.. Clear pics..

Let me know what you think.

Sorry to say it but that card looks so bad i would be worried about hooking it up to the psu & running it in a motherboard. That damage is serious - looks like it was dropped onto concrete or trodden on. Shader chip is chipped, IC's are bent, memory chip is chipped, caps broken off etc. I hope you paid very little for it. I would just get a new card if i were you.

[eclypse]

All good now.. I've used the card for a resistor that i needed to fix my 8800GTX card that i damaged trying to volt mod.

Also theres a guy that needs the card for a memory chip replacement. So in the end 2 cards were fixed cause i bought this dead card hehe.

[Timbosan]

nice, always good to recycle ;)

And i thought you bought the card to give to your grandson :lol:
