blown caps on 9600 gso

Re: blown caps on 9600 gso

I actually live in northern Minnesota about 10 miles from Canada. There is a place called Digikey that is about 50 miles from my location that has alot of different electrical components. I searched my bad caps on there website and came up with no results. I was wondering if you had the specifications of the caps that are on this board. I have the voltage and I know is that they are radial cans for through hole mounting. I just need capacitance, the width in diameter, and the lead spacing. Then I should be able to order these and replace them on my card. Thank you for your help

Re: blown caps on 9600 gso

Also would an overheated computer cause these caps to burst?

Re: blown caps on 9600 gso

If the capacitors were with FZ on them, no... these particular capacitors are simply of bad quality, poor substances inside them cause them to almost always fail after some time.

Generally, heat affects the life of capacitors but good capacitors will stay within specifications for years as long as they're subjected to average temperatures (30-60c).

Digikey is great store.

As you have the card in front, you should be able to measure the diameter of the capacitors with a ruler - you can put any diameter there as long as there's room for it. Look at the board, there should be a circle where the capacitor should be placed.

The lead spacing is the same... it's just the number of mm between the holes on the board - you can turn the card on the other side and just measure the distance between the solder points of the capacitor wires. Generally, the distance is standard for capacitors with the same diameter so whatever uF or voltage value the capacitors have, the lead spacing is the same for that diameter. For 8mm diameter, the spacing is usually 3.5mm while for 10mm diameter, the spacing is usually 5mm - the capacitors in the links below follow this "rule".

If you can't find capacitors with voltage identical to the one listed on your capacitors you can pick capacitors with higher voltage ... just the uF value should stay the same.

The post above says these are the caps:

3 x fz85 1500 6.3v
1 x fz83 1000 6.3v
4 x fz86 470 16v

You never said what capacitors are on YOUR video card - we can't guess or say they're 100% what the other guy had. Look at your video card and read what's written on them.

On digikey, these would be good replacements for the capacitors mentioned above , from best to less

(you can also find larger diameters, 12.5mm for example, but 8mm and 10mm are good diameter for video cards

Re: blown caps on 9600 gso

Thank you very much. My caps that burst are;

FZ87 1500 6.3v x 3
FZ83 1000 6.3v x 1
FZ86 470 16v x 2

Re: blown caps on 9600 gso

Ok, the 1000uF and 470uF capacitors are the same as the ones above. FZ87 is a different series than FZ85, but it shouldn't matter - all the capacitors I linked to should have better or equal characteristics.

Just determine the lead spacing and the diameter and pick whatever's is more convenient for you from the links I posted.
What I'm trying to say is all are good but the best that would work may cost 1$ per piece while the second best costs 0.5$ when bought in pack of 5 so as you have to buy 3 pieces, it may be a better and cheaper choice to get the second best.

Re: blown caps on 9600 gso

As long as this solves my issues with the computer crashing then price isnt really an issue. I just didnt have the budget to buy a new card. Im currently doing research on a new case and a very good cooling system. Thats why I asked if the temperature inside the case made these burst. Thank you for your help and responding quickly.

Re: blown caps on 9600 gso

Crashing could also be caused by poor quality electricity coming from the power supply.

For example, the capacitors inside the power supply could be turning bad due to the high heat inside it and because everything is crowded inside, so they no longer filter and regulate the power sent to the computer properly.

When this happens, the capacitors on the motherboard and the video card are forced to do extra work and may be subjected to higher ripple than what they're designed to support. If the ripple coming from the power supply exceeds what the capacitors tolerate, they may go bad prematurely.

So I would also check the power supply, inspect the capacitors, see what brands are inside and how they look - ideally, if the power supply has some age on top of less reliable brands of capacitors, I'd desolder a couple of capacitors and test them.

Crashes can be caused by ageing/dying capacitors near the cpu socket, which regulate the power the CPU receives, so check those capacitors as well.

Read what those capacitors have on label and type it here - there are some series of capacitors from some brands which had manufacturing flaws so those series have higher rate of failure. In this case, you should replace those as well.

So replace those capacitors anyway, you have to - but if you still have crashes, inspect the power supply and the motherboard.

Re: blown caps on 9600 gso

I checked everything that I could see without having to tear the system down. Now that I just have the one GPU running, the system runs fine with no crashes, besides the video isnt running as smooth without the extra memory that it was relying on from the other GPU. I might order my new case this week and when I move my components to the new case I will check everything thoroughly. My PSU is an Ultra LSP750 750-Watt which is SLI ready. I built this system December 2008 and it runs nearly everyday all day. When I get the new caps and install them I will let you know how it is running.

Re: blown caps on 9600 gso

more investigation suggests that the fz03 is actually a fz83.....

They are FZ series Sacons.

The numbers after the FZ are just the date code. [They aren't important.]

Re: blown caps on 9600 gso

I got my new caps yesterday and installed them. The card runs good now with no crashes. I ran a few different games and programs that usually would have caused the system to crash. Thank you again for your help

Congrats!

Re: blown caps on 9600 gso

almost 2 years on and my card is still working fine!
