Vista - SATA power to IDE power? Is it possible?

Hey everyone! I purchased a Dell Inspiron 537 a few days ago. I have an available PCI-Express slot. I went to put a Nvidia Geforce Verto 9600GT 1GB graphics card in today and I saw all the power connectors were SATA, or so I am told (a friend of mine looked at it.) So I looked online for a wire or connector to convert one of the available SATA power connectors back to an IDE power connector, as I need an IDE connector to plug into the 6-pin wire to power the graphics card.

So heres my question: Is there any website that anyone knows of to order the wire/connector convertor for it? Or does such a thing exist?!?! Also, do they make a 6-pin wire that is powered SATA and not IDE?

This is my first post and I am sort of a newbie at fixing computers, so any help or suggestions would be really appreciated! Thanks in advance everyone!
