The XG Station connects to any notebook’s ExpressCard slot and provides a PCI Express x16 slot for graphics cards. Since ASUS has opted to equip the XG Station with a standard PCI Express x16 slot, the station can be equipped with any PCI Express based graphics card: AMD, NVIDIA or even Matrox. ASUS launched the default XG Station with an NVIDIA 7900GS powered graphics card.

The XG Station is powered externally.  A separate power brick plugs directly into the adaptor."
