PCIe power connector???

Hi, I got really lame question, but I thought its better to ask.

Anyways, new video cards usually have ~6-pin pcie connectors to connect them to psu.

But what I don't understand is what difference does it make if its connected or not?

I built 2 systems and I never connected those video cards and they work fine.



Sorry, for such a lame question.

    Some cards perform better with more voltage, the mobo generally regulates the pci voltage to a certain range (which you can alter slightly), but with it hooked to the psu the card can draw more power.

    Or atleast this is what the crystal ball told me.

    Anyone knows if 7600gt would benefit?

    I always thought I was good in computers, until this day.

    Don't 100% trust my info.

    I'd actually divide my awnser by pi or what not.

    If it has the a place to plug the power in direct, you are ment to use it. That is why it is there.

    Also if you use a mighty big card make sure your PSU has enough juice to run it. If your card needs more than 300 Watts, it will say so in the minmum specifications on the box.

     

    I am led to believe that while your card may function without the correct power supply, each time you turn on your computer you are degrading it.

    It was either a 5900 or 6800 that was the first Nvidia card I ran into that required extra power. I did the samething when I first saw the plug, I didn't even connect it.

    If you don't plugin the power to the video card the drivers used to say something like "WARNING: Power cable not connected. Currently running in low power mode." It would run real slow. You definetly need to connect it to your power supply. If your power supply doens't have the right cables you need to use the (2) 4 pin to 6 pin converter, which probably came with the card.

    Yes, plug it in, its not just for looks. Very few of the 7600 series cards have those, I know none of the 7600GS's do, and I know that the EVGA 7600GT @ 560mhz dosent either, so im guessing you have the XFX one thats OCed to close to 600mhz?

    Thank you all for your answers, now I'm more educated.

    I will connect it and will see how its going to work.
