Welcome to a laptop battery specialist of the dell laptop battery
So, my inclination is to go with the Molex instead of messing with the 6 pin? Or would the 6 pin be the preferred for the 6 pin port on the new card? Guess I would need to confirm that with a Nvidia tech maybe? Although looking at the six pin on the adapter, the yellow (2) wires from the 2 Molex male connectors are on the top side of the six pin and the brown and black wires go to the bottom of the six pin. ( I am assuming that the brown wire is a ground, although I don't see it listed for voltage wire color coding on computers) Given that configuration, either of the computer 6 pins would work, but not sure about the middle 12v wire if it is needed on the card or might cause a problem. The port on the card has six pins, but the Molex to 6 pin adapter does not have a pin in the top middle, just the 2 outside which have the 2 yellow wires going to them.
One other thing, the card for the S-video, TV, audio ect. that is directly with battery such as dell Inspiron 1521 battery, Dell Inspiron 1720 battery, dell Inspiron 1525 battery, dell Inspiron 1526 battery, Dell JWPHF battery, Dell XPS L501X battery, dell Inspiron 1420 battery, dell WW116 battery, dell Vostro 1500 battery, dell Inspiron 1545 battery, dell J399N battery， dell Inspiron 1440 battery above the graphics card, will be in the way of the new card (due to fans on top) if I put it in the same slot as the existing card. Can I put it in the vacant slot below where the existing card is? If not, can I just remove the S-video, TV, audio card, as I am not using it for anything?
Well, firstly, turn off your system, unplug the PSU cord, and yes, turn off the PSU as well. (there should be a off-on switch at the back of your PSU. [don't get this confused with a little red switch, that red one is for PFC [power factor correction], don't mess with the red one.)
Fiddle with the little white hinge on the PCIe slot (try lifting it or sliding it) until it goes loose, then pull out your card. This may take a little force so don't be scared, but be careful too.

grab your new card, and whilst taking appropriate ESD precautions, insert the card into one of the longer PCI slots, preferably the one closest to where the CPU is. This will probably take a little bit of force, and you may hear a click when you push it in. Then, screw in the card's bracket to the case, to fasten it.
