PowerMac G5 Video Card

I have a G5 2ghz Dual Core (late 05) that doesn't have a video card. If I buy a nVidia 6600, will I also need to buy a PCI-e power cable such as this: eBay - New & used electronics, cars, apparel, collectibles, sporting goods & more at low prices

the 6600 I'm looking at says it doesn't include any kind of cord with it, I've looked all over the internet and can't find a definite answer.

thanks!

no the 6600 card doesn't use or need a power cable
its just plug & play

thats the power cable for the nvidea 7800GT or Quadro fx4500 cards

Thanks so much!
