Notice:
◆ The slot with bus bandwidth of PCIe x16 is backward compatible with PCIe cards of
PCIe x8, PCIe x4 and PCIe x1. Up is incompatible, that is, the bandwidth of the PCIe slot
cannot be smaller than the bandwidth of the inserted PCIe card.
◆ Full-height and full-length PCIe slots are backward compatible with full-height and
half-length and half-height and half-length PCIe cards; slots with full-height and
half-length PCIe slots are backward compatible with half-height and half-length PCIe
cards.
◆ The power supply capacity of all slots can support a PCIe card with a maximum of 75W,
and the power of the PCIe card depends on the model of the PCIe card.
