• Operating environment: Compatible with common desktop operating systems (driver support may be required)

How to use

Power down the computer and disconnect it from the mains. Open the PC case, locate an available PCI Express slot and remove the corresponding expansion slot cover. Insert the adapter into the slot firmly until it seats in place and secure it using the case's retention screw. Close the case, reconnect power and boot the system. Install any necessary drivers supplied by the operating system or the manufacturer to ensure the adapter is recognized and configured.
