New PC- Video card has no power- HELP

  1. Hi,

    I have been following this forum for a long time and now I finally have something to post about.

    I just ordered a new system:

    Asus a8n sli
    amd 3,0 venice
    1g corsair
    geforce 6800
    300 gig maxtor

    My problem is after assembling everything the computer powers up, but the video card has no power although power is blugged in. The fan wont start spinning and I have no picture on the monitor. Everything else is working including roms, hardrive, fans lights and I have no error light or beeps.

    So why does the card get no power????

    Just went and picked up a 6600gt, because I thought the card was DOA but this one does not start either.

    I really need help with that, Thank you

    Tom

    I dont think it would be two vid cards with the same problem, You are connecting up the power supply on the vid card arn't you, i ask because many dont know that you have to connect them to get power, also what wattage is your power supply it maybe that there isn't enough power to run the card, no less than 450 watt is needed.

    Yes, I plugged in the video card and triple checked if the plug has power. The power supply is a 350W Turbolink that came with the case.

    So you think I need a different power supply and that is the problem. I used an online calculator and it said I would need ~300W for the system.

    Update:

    I changed the motherboard with a a8n sli deluxe and changed the power supply to a 500W - still no power on the video card.

    Is there a cable I missed - a connection I didnt plug in ? something? help me pls.

    Update: I am now getting one long beep and two short beeps indicating that there is a video card problem - since I exchanged it with a 6600gt what are the odds of two bad video cards?
