2-in-1 PCI-E Gigabit Ethernet and USB 3.0 Hub

This SMUGDESK expansion card adds a wired RJ45 network connection and three USB 3.0 ports through a single PCI-E X1 slot. It targets desktop PC owners who need both a stable Gigabit LAN link and extra high-speed peripheral ports without using multiple expansion slots. The integrated design suits gaming, 4K streaming, large file transfers and general office connectivity.

Plug-and-play PCI-E X1 installation

Insert the card directly into a standard PCI-E X1 slot on the desktop motherboard; mainstream Windows systems typically recognise the hardware automatically for driver-free setup. The board uses an industrial-grade controller chip and reinforced PCB for low heat generation and long service life. Ensure the bracket aligns with the case opening and the card seats fully to avoid intermittent network or USB detection issues.

Check for a free PCI-E X1 slot and OS support

Verify your motherboard has an available PCI-E X1 slot and that your operating system is compatible with automatic driver recognition. The RJ45 port follows IEEE 802.3 standards with 10/100/1000Mbps auto-negotiation, while the three USB 3.0 ports deliver up to 5Gbps and remain backward compatible with USB 2.0 and USB 1.1 devices. Buyers needing fibre connectivity or additional Ethernet ports should look elsewhere.

Questions about this item

How can I confirm the Ethernet link is running at 1000 Mbps after installing the card?

Open the network adapter status in Windows; the Speed field will show 1000 Mbps when the link has negotiated the top rate defined by IEEE 802.3.

What comes in the box and do I need any extra cables or brackets?

The box contains the PCI-E expansion card with its integrated RJ45 port and three USB 3.0 ports; you only need a standard Ethernet cable to connect the network and a free PCI-E X1 slot on the motherboard.

Should I choose a different version if I only need USB ports or only need Ethernet?

This single model combines both functions; there is no separate Ethernet-only or USB-only variant listed.
