PCIe x1 Combo Expansion Card, 3-Port USB3.0 + Gigabit RJ45 LAN Adapter with 4Pin Power Connector for Desktop PC

This all-in-one PCIe x1 combo card integrates three USB 3.0 interfaces and one gigabit RJ45 network port, realizing USB peripheral expansion and wired network upgrade with only one PCIe slot occupied. Equipped with a 4Pin power supply port, it solves insufficient power issues that lead to unrecognized external hard drives, high-power USB hubs and other devices. The gigabit Ethernet port automatically switches 10M, 100M and 1000Mbps network speeds to support smooth internet access and large file transmission. USB 3.0 ports deliver 5Gbps high-speed data transfer for flash disks, cameras, external SSDs and other peripherals.

Independent circuit layout effectively avoids signal crosstalk between USB and Ethernet channels to ensure stable long-hour operation. Standard full-height bracket fits most ATX desktop chassis, plug-and-play under Windows and Linux systems. It is an ideal upgrade accessory for old desktops lacking enough USB ports and stable gigabit wired network.
