  1. i just got a new pc, a cyber power pc, and i got a 9800gt 512mb card to go with it.
    when i plug it in i get no display and the fan isn't working either. it says it needs 400+w for the card and my system has 420w is that not enough for the card? what could be the problem?

    usually what i read is that power systems don't run at its peak. if it is asking for a 400w power supply you might want to get something around 550w labeled on it.

    Make sure that the card is seated properly and check what you PSU's +12v rail amperage is. Even though you power supply is rated at 420w it may not be able to provide the card with sufficient power. The box that the 9800GT came in should specify the amperage required for it to operate. The 9800GTs I have seen require at least 26 amps on the +12v rail so I'd say you'd be safe with 30 or so. Also, double check that you have the power connected to the card properly. The fact that the fan isn't running is a little strange...
