Force3D HD4670

[robertvan1]

I have two blown caps on this graphics card. One labelled 'FZ77 1000 16v' and another labelled 'FZ77 10000 16v'. I assume the former is a 1000uf cap, but can the latter be a 10,000uf? All replacement 10,000uf caps I have seen are larger than the 10mm diameter of both the blown ones on the board.

Strange, I think they both are 1000uF.

The 'F' suggests Sacon FZ series, which is VERY widely know to blowup on graphics cards!.

agreed

There's no such thing as a 10,000uF cap on a graphics card. It must be a 1000uF 16V. Do you have a picture of the cap(s) in question?

depending on where you'd like to order from

It is.

All of the Fz's need to go. They are like little grenades when they blow... the most "explosive" bad cap ever made.

Even more so when they lack vent stamps

Awesome!

robertvan1:
If there are any more sacon FZs on that graphics card, replace them too!

Re: Force3D HD4670

is there any way to tell if these are polys post-explosion?

Xtra low esr? Thats the only one I know.

Or, just look up the series from the codes stamped on it.

Re: Force3D HD4670

Turns out they both did say 1000, I was just reading it wrong on one. Have ordered some replacement caps, wish me luck for when they arrive!

Re: Force3D HD4670

I successfully recapped the card today and it's working great! Thanks for the advice guys.
