asus p5wd2
intel D950 3.2 ghz

But will my powersuply be enough ?
If not ,whats the best gr.card i should get that will run with my powersuply?

ps. I'll only change my power suply in a year or so when i do a huge upgrade (Vista and DX10)

  1. Heres your answer

    Minimum System Requirements

    * Intel Pentium IV (and above), AMD K8 (and above) or compatible with PCI Express slot
    * Minimum 128MB of system memory
    * Installation software requires CD-ROM drive
    * Interactive Program guide requires Internet connection for listing updates
    * Power supply of 400 watt(550W is recommended for SLI mode) is highly recommended for system stability

    Yes your supply meets what is needed.
  2. You might need to change that, what brand is it and how many amps on the 12v rail ? You know you could just google "7900GTX power requirements" ;)
  3. Yea ,my bad .But i just want to hear what the pro's say about this :wink:


    Edit : how do i get the info about the amps on the 12v rail
  4. Consider replacing it. Heres something that'll work:

  5. To find amperage the easy way, just look at the info posted on the side of the unit.

    Or you can just google your model number. Either way, unless its a high quality unit (highly doubt that) I wouldnt recommend using it with a 7900GTX
  6. Oh and a 7900GTx might no be the best buy you can do, they practically been replaced by the 8800GTS, you wont get any price drop and you can probably have a more future proof card easily.

    There's a label on the side of the PSU that'll tell you how much amps you have on each rail.

    Or just give us the model...
  7. thx ,i'll just open my case. But if the 7900gtx is to strong...should i go for the 7900GT or maybe 7950GT ?
    Im planning on a big upgrade next year or so .
    Thx for the input :!:

    Ok,i've opened my case and here's the info i've found :

    Model :LPK12-420w
    Voltage :230v
    Current : 5A
    Frequency : 50Hz

    Now plz bear in mind that i just need a good GR.card to get me throu the next year untill i build a new pc (new mobo,powersupply,etc)

    I was talkin' about the 7900GTX ,coz i think i could do a good deal on e-bay.
    But if i dont have enough power...well i would consider getting 7900GT,7950GT or a 7900GTO.
    All i need is a good card that will let me play the latest games untill i do a big upgrade.

    ps: dont mind the spelling mistakes,english is not my native language. :wink:
  9. Nope...that PSU wont do it, its linkworld and its crap.

    Gotta grab something else I"m afraid.
  10. But a 7900GT will work fine , won't it ? :(
  11. I wouldnt chance it....but there's always a way to find out :lol:
  12. So whats the best card i could get to work ? :? (without probs )
  13. I think investing in a PSU would be wise. cheap PSU can cause instability and crashes. Even if you go for a lesser card, you could see some instability just because you will be addind some load on the PSU.

    Thats my .02 but good ~400-500 psu can be found for under 100$. I think it would a good investment!

    Sure,but mine is a 420w psu and i always thought that it would be enough.
    And its only 6 months old. :cry:

    So anyways ,is it hard to put in a new psu ? If not i might consider getting a new one. What brand should i look for ?
    Cheers.
  15. thats the thing. if it was a qaulity 420 watt unit, you might be able to get away with it. however (no disrespect) you don't. Its not necessarily about wattage, but amperage off the 3.3v 5v and most importantly 12v rails.

    As said above, it can only benefit you to invest into a decent PSU.
  16. K; thx for your time. :)
