    Voltage question

    My 8600 GT video card went out a few days ago. 3 FZ caps blew on it, two 1500 6.3V and a 1000 6.3V (I plan on replacing all 10 FZ caps). I have some soldering experience but I never replaced any electronics on anything computer related before.

    In the recap tut overview it says you can use caps rated for voltage over the ones you are going to replace (16V for a 6.3V and such).

    My question is; Is having higher voltage rating better?

    I'm thinking that it would do better in the case of a power surge and perhaps give better electric flow. I really don't know, perhaps it doesn't effect anything.


    I'm sorry if this has been over before in a different post, I did a search and I didn't see anything like it.

    Re: Voltage question

    In general, you will not gain anything by using higher voltage caps. However, since the higher voltage caps often have a bigger physical size, they will have lower ESR and higher ripple tolerance, as long as they are from the same series. If the circuitry benefits from this, increasing voltage will help.

      Thanks for clearing that up for me.
