Gainward GeForce FX5200

Two bulged caps

Bulged and leaking

Oh, looks like a new crap cap brand!

Double MOSFET is also fried

Replaced 5 crap caps (the two bigger ones were not replaced as they're TAICONs)

Double MOSFET replaced too

Heatsink attached (removed a piece of it so it does not heat up the cap in the top right corner anymore)

Re: Gainward GeForce FX5200

I was curious on how you determined the correct MOSFET to use. I googled the number on the old one and came up with a data sheet. Is this the correct one?
APM7313

Just trying to hone my skills in case I ever have to replace one.

Re: Gainward GeForce FX5200

Yes, that's the original one. The replacement is from dead Radeon 9500 card and it's SI4804DY or something like that. The parameters are not the same but very close.

Thanks Rainbow nice post.... lots of pics too

nice big heat sink to cook everything, but thats the way it goes I suppose.

I guess there is a reason (as in a standard that was started) as to why all video cards in tower end up with the heat sink face down
(ok yes there are fans in the case that stir the heat around)

Here a link to the other Dual mosfet SI4804DY

I'm surprised they bothered soldering the fan power connector on a passively cooled card. Most manufacturers will cut every corner possible to save money.

Re: Gainward GeForce FX5200

It's probably cheaper to put the connetor on all cards and just install different heatsinks than to make two different cards.
The heatsink is really, really hot. No wonder that the caps failed.

Maybe the manufacturer decided that the end-user who bought the card could want to replace the passive-cooling solution with an active-cooling solution.
