according to the article on the Inq it looks like Nvidia is asking for another 75w for their next gen pci-e graphics cards. . .
We also heard that Nvidia asked PCI-Sig to let it use two power connectors for the card, each providing 75W of power. If the Sig agrees, it seems that Nvidia next generation card might end up drying 225W of power. It's simple maths, 75 W from PCIe motherboard connector, and two times 75 from a six pin power connector.
