Note: When one or two 75-watt PCI-Express* graphics cards are installed, the system will supply power for that slot during the power-on sequence or hot-add process. Then, on finding the violation of the configuration restriction, the system halts the power supply to the slot. In the case of a hot-add, since the operating system cannot identify the hot-added card as 75 watt, the 75-watt card cannot be hot added in restricted cases.
