Replacing FZ78 with a solid capacitor

[blazer249]

Can someone tell me what capacitors can I use for replacing the FZ78 (1000uF 6.3V) on my video card (Forsa Nvidia Geforce 9600GT)?
Can I replace them with solid capacitors? If yes what models would you recommend?

Thanks!

usually these

but tc's out right now

You should have no problem using lytics though

these should be fine

though i'm not sure what height/radius those on your card are. I bet they're under 14mm though

Hey,
Thank you for reply but I've said FZ78 (1000uF 6.3V) :p
Anyway I will wait for others tips.

Re: Replacing FZ78 with a solid capacitor

When you replace solid capacitors (polymers) with electrolytic capacitors, it's often recommended to go up a bit in capacity.
Also, for the purpose that capacitor was used, going up in capacity a bit won't cause problems. The capacity needs to be just over a minimum value.

So the 1500uF Rubycon capacitor that he recommended is a very good choice to replace that Sacon FZ.

If you have to get 1000uF 6.3 here's what will work...
...but since you had to be a jerk and didn't enter the country you're in, i can only recommend alternatives for US

You kinda seem to forget that Sacon FZs are lytics.. :P
No need for increased capacitance.

I've attached the datasheet of those junk caps for specs comparison..

Re: Replacing FZ78 with a solid capacitor

No, I knew it's electrolytic. I clarified that through private messages, he contacted me privately.

When this series was made, the specs were more or less in the polymer/solid capacitors range... nowadays those specs are achievable by some electrolytics, though kinda hard at that height...

If you're gonna use fleabay, only ever use sellers egekecu/PCMCS or Audjade. Many others sell fakes.

As for your original question, use http://www.ebay.com.au/itm/4-Nichico...item45fdff1b5c to replace the FZs. The slight capacitance drop shouldn't be a problem.

If you were going there then they also have 6.3 v1000uF

Re: Replacing FZ78 with a solid capacitor

how about measuring the voltage at the caps you wish to replace?then i can suggest something based on my experience.something you can buy at the badcaps store and skip the ebay minefield.

Re: Replacing FZ78 with a solid capacitor

you can go up or down in cap within reason with polys. Actually i've seen people who replace 1500 with 330 or 560 16v caps on input vrms before with no problem

lytics are another story. Usually same or higher, but within reason

Re: Replacing FZ78 with a solid capacitor

I've replaced the bad capacitors with original Panasonic 1000uf 16V.
The big thanks goes to Mariushm.
Anyway thanks for the answers people
