Specification: Model: PCIE 1 to 4 PCIE USB Bus interface: PCI-E x 1 (compatible with 4x / 8x / 16x / graphics card interface) Interface: PCI-E USB interface * 4 Dimensions: 120 x 55 x 75 mm. Compatible system: DOS / Linux / WinXP / Win7 / Win8 / Win10 / Win11. NOTE: ● The 4 USB ports on this adapter card are PCI-E signals, not USB signals, so they cannot be connected to USB devices. ●Turn off your computer and any other connected peripherals before use. Unplug the power cord from the computer. ●. Since low-end motherboard chipsets do not support multiple graphics cards, it is recommended to use motherboards with B250 or higher chipsets. Before use, please calculate whether the power supply has enough power and whether the graphics card has enough cooling space. ● The number of graphics cards supported by the motherboard and the motherboard are different. Therefore, you must test it yourself. ● Because WINDOWS limits the number of graphics cards, only 8 cards can be recognized under WIN10, and only 6 cards can be recognized under WIN7, so the revised graphics card driver must be used. It is recommended to use the same type of graphics card on the same motherboard. ● 8 or more cards must use the LINUX system. Package: 1*PCIE 1 to 4 PCIE USB Riser Card
