Noob PSU question
  • coffeecoffee December 2007
    Thinking of picking up a 7600GT to replace my exploding 6600GT; system requirements are "400W Power Supply, 26 Amps, 12 Volt Rail". I'm not too sure about what the 12V rail means. The sticker on my psu shows +3.3V @ 26.0A, +5.0V @ 32.0A, and +12.0V @ 13.0A.

    Will i be able to play games again?

    ok disregard that question, heres a different one. If connect two 12 volt @ 18A rails to a graphics card with a 4-pin Y adapter, will the total available amperage be 36?

    It should, but you might want to consider upgrading your power supply. You don't want to push your PSU too hard.

    i am planning to get an OCZ 600W power supply. it has four 12V rails @18A. my video card states a 12V rail @ 18A minimum req. my concern is that one 12V rail will provide insufficient power to the card while running moderately stressful games like FEAR on higher settings.

    You're absolutely right, and I don't need to go into details why. Do yourself a favor and upgrade to the 600W.
