  1. I just got a new video card and power supply to support the video card, but i don't know how many watts my motherboard can take. Could anyone help me figure that out because i couldn't find it on my bios.

    The M/b will only take how much watts it needs, even if you had a thousand watt PowerSupply.
    It came with a 305 W Power Supply
    Anything better than that will do

    As long as the Power Supply is the correct voltage for your country (most likely yes) 115 or 230 V
    Then you can a 2000Watt power supply

    There are many many other issues
    20 or 24 Pin Main Power Connector
    Sata Power Required
    Weight (yes the heavier they are the better they are)
    Internal Fan Size
    Dual 12V Rails

    The list goes on and on

    Now I might get other support members, stating the total power should not exceed twice the power required
    And lots of other info

    But anyway, haven't you bought one already?

    kimsland, multiple 12V rails really aren't as good as a single, if I'm not mistaken.

    No, as kimsland said, you could theoretically have a 2000 Watt PSU, and not have to worry about anything, and as kimsland said, the computer will only take power that is needed.

    There is no reason to worry about multiple rails vs single rails in a Dell. Ever. The golden rule is to not pay extra for multiple rails, as it is mostly marketing. But a unit like that is usually solid and dependable for other reasons. The Dell power supply will handle most video cards just fine, but for a high end card, you need to go up to 450 or 500 Watts... Quality is significantly more important than Watts. So get a solid name brand such as PC Power and Cooling, FSP Group, Corsair, OCZ, or about 87 others. There is a list published on this forum that is close to excellent.

    Just wondering, why did you buy a new PSU? Unless your new card is not from the GeForce 8600 series or an HD 3850, your current PSU would have been fine.

    Rage, are you saying the 8600 will run on a decent 305watt psu? Thanks, I never knew that!

    I don't know about others, but that PSU has 22A on the +12V rails, beefy enough for an HD 3850 or an 8600GTS.
