Help with identifing Caps from a 8800GTS Video card.

[eclypse]

Hello,

I just bought a damaged EVGA 8800GTS 360MB 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.

I think they're Sanyo Oscon SVP series, 180uF, 16V, possibly manufactured in the 48th week of 2006.

Hey thanks!

So i could use any other brand Alumium Cap rated 180uF, 16v?

Can you tell what the size of the cap is? heh i dont want to order caps of the same rating and they come in too large to fit.

I got a reply from another forum.

repair with those.
these caps are of better quality.

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

Would these work? Is there anywhere else to buy this type of cap in the states?

Yes, they are ok, but Oscon SVP series is probably the most reliable polymer cap.
SVP series isn`t just an aluminum electrolyte capacitor, they are solid polymer too.

I hope your have realized, that the broken black component is not an capacitor.

Thanks for the info.. Just wish i could find somewhere in the states to buy some.

Yes i know that the black speaker isint a cap.. I was refering to the base of the caps.. Theres supposed to be a base on them as the original owner broke them off to reattach the caps.

Boy the previous owner certainly made a mess of that board.

Why is there a speakker on a graphics card? It seems unsual to me.

You can buy Vishay/Sprague replacement 180uF 16V from Mouser

Thanks alot!

About the speaker.. Its just used as a warning, as it will go off if you forget to plug in the power cable on the video card when you power up.

Surface mount products can be harmed using a soldering iron. They are intended for use with a specialised solder paste that does not create as much heat stress. It is a case of having the right equipment.

Ok thanks for that bit of info.. I'll go with what you suggested then.

Don`t get me wrong, you can use this UCC caps, they are used on many components recently.
Mauser does carry the Oscon caps too. Just click on line pdf cataloge, same page.

Ok.. What tools do i need IF i wanted to get the same surface caps and do it right? What kinda cost does the right stuff go for?

Heres anohter area of interest.. if anyone has any advice on how to repair a tear in the pcb i'm all ears!

The original owner sold it to someone overseas and it was damaged in shipping.

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.

Re: Help with identifing Caps from a 8800GTS Video card.

The circled item is an inductor, it is destroyed, important magnetic material is missing. I also see a disturbed chip at bottom middle of photo. All very suspect. I suspect the board is not worth fixing. Certainly you will need to find out if you can obtain a replacement inductor.

So real problem is inductor, next may be chip and if the PCB is damaged it may be very difficult to fix in that the connection to the in board multilayers may be a broken.

We shall see once i remove that broken chip. I do have a 7900GTX card that is damaged that i can use spare parts from. Theres a few of those 1R0 chips on there that i could use. Also the seller did have that little tiny C33 resistor.

I do hope to hunt down somewhere to buy a few of those 1R0 chips.. That other card i have is a some what working spare as it works for 2D but the picture scrambles durring 3D.. It was a new card and i slightly chipped the GPU core putting on a 3rd party heatsink. I see no other damage and it worked perfectly before i chipped it so it must be that. Though i could take that 1R0 chip off it and find a replacement for it later on.

From the pic it looks like just the top layer of the PCB thats tore.. Prob a broken trace atleast as thats what the owner said.

Re: Help with identifing Caps from a 8800GTS Video card.

Wow.. Thanks for the info. Though i have some questions for those who know.. is it possable to solder on a surface mount cap with just a low wattage iron? Say 12 WATT? Do i have to use a heatgun and the right tip?
