Came across this thread about graphic card power consumption:

Seems the Nvidia 7300LE or GS is the way to go if you have to use PCI-Express.
Ends up being around $50 from newegg.
Just goes to show that my friend was right when he said expect to pay far more than you originally planned for this project. Everytime I turn around, it's another $50 here, $50 there.
If anyone has a different opinion on a PCI-Express card let me know, but 16w-24w seems pretty low (if accurate).
Edit:
Double posted =(
