Thinking of getting a better GFX card, what PSU do I need?

    Ok, I have had my eyes on this "Zotac 580GTX" card for some time, since no one else is buying it they have lowered the price from around 470$ to just 400$.

    Problem is if you look at my systems specifications, my powersupply is rather weak (well.. very weak).
    These are the brands they currently have:
    Antec
    Cooler Master
    Corsair
    Fractal design
    FSP
    OCZ
    Zalman

    I'm asking you, because they just want to "sell" whatever they can to earn money, and I do not know if what I get is overkill or good or what..

    They do however only have 1 Zalman PSU in store, and it's a 750w.

    I'm running a 750w OCZ and it hasn't given me any problems.
    SaiZo says thanks.

    i would go for FSP or Corsair, Check this link out http://www.techpowerup.com/forums/showthread.php?t=39758

    EDIT: Go for some thing around 750w and when you find a PSU check for reviews on the net see what others say ( [H] and Jonny Guru come to mind ).

    Remember that links old now but should still give some insight.

    Thanks for the replies. How many watts should the PSU have?

    AT least 750w for a system like yours + a GTX 580.

    +1

    Yeah 750w-800w, i like to double what the system will use. O yeah check if you can get the manufacture warranty and not just the shops as the Corsair one might have a 7 year warranty with it.

    Minimum spec is a 600W, max power draw of the card is around 324 watts, thats not overclocked of course, I would also be inclined to go for a Corsair, FSP or one of the better OCZ models and probably at least 700W to give you some headroom.

    Yeah I would go with a corsair personally got a tx650 and its never gave me a hiccup once, its about 2 year old i think now good quality PSU's can be quite steep in price someplaces but if you shop around am sure you will find something, also i agree with the rest 750+ is good sounding for that system :)
