PCIE X8 to 2x 10Gbps RJ45 Network Adapter - Dual 10GbE PCIe Card

In this review the FebSmart PCIE X8 to 2x 10Gbps RJ45 Network Adapter is evaluated for desktop and server use where high-throughput copper Ethernet is required. The bottom line: it is a practical, no-frills way to add two stable 10GbE RJ45 ports using the original Intel X540-AT2 controller, and it delivers consistent multi-gigabit links on supported Windows and Linux systems. Installers and small lab owners will appreciate the straightforward fit and driver support, while buyers must confirm an active PCIE X16 slot wired for X8 lanes to reach peak speeds.

Key Features

• Dual 10GbE ports: Two 10GBASE-T RJ45 interfaces provide copper 10Gbps connectivity for workstations, servers, and NAS without fiber transceivers.
• Intel controller: Built on the Intel X540-AT2 ethernet controller for proven firmware and driver compatibility across Windows Server and common Linux kernels.
• Flexible cabling: Supports Cat6 up to about 55 meters and Cat6A up to 100 meters so you can use existing structured cabling for short-to-medium runs.
• PCIe X8 interface: Uses a PCIe v2.1 X8 lane interface compatible with X8 or X16 slots, enabling high throughput when the slot provides the required lanes.
• Virtualization features: Hardware support for SR-IOV, VMDq and port partitioning helps offload networking tasks in virtual machine and soft router setups.

Who It's For

The adapter is aimed at power users, IT hobbyists, and small business servers that need inexpensive 10GbE copper on commodity hardware. It is a sensible upgrade for desktop PCs used as soft routers, small NAS systems, or development machines where 10GbE to the device reduces transfer times.

It is not intended for systems without an available PCIE X16/X8 slot wired for X8 lanes or for buyers who require SFP+ fiber optics. Users who cannot confirm lane availability or who need passive low-profile solutions may want to look at other form factors.

Pros & Cons

Pros

• Reliable Intel X540-AT2 chipset ensures wide OS driver support and stable operation.
• Two full 10GbE RJ45 ports provide flexible copper connectivity for many environments.
• Easy to install with both full-height and low-profile brackets included.

Cons

• Requires an active PCIE X16/X8 slot wired with X8 or X16 lanes to reach full 2x 10GbE performance, which can be limiting in some PCs.
• Connection speed feedback is mixed among users, so actual throughput depends on cabling and host lane configuration.

Specifications

Our Verdict

The FebSmart X540T2 adapter is a pragmatic way to add two 10GbE copper ports using a trusted Intel controller, delivering strong value for desktops, soft routers, and small servers when the host provides the required PCIE lanes. Confirm slot wiring and use appropriate Cat6A cabling for best results; for those constraints it offers reliable multi-gigabit networking at a reasonable cost.

Frequently Asked Questions

Will this card work in a standard PCIe X16 slot?
Yes, it works in a PCIE X16 slot but the slot must provide X8 or X16 lanes for full performance; otherwise the card cannot reach expected 2x 10GbE speeds.

Does it support Linux and virtualization?
Yes, it uses the Intel X540-AT2 controller with ixgbe drivers for many Linux kernels and supports SR-IOV and VMDq for virtualization.

What cable type is required for 10GbE?
Cat6 is acceptable for shorter runs up to about 55m; Cat6A is recommended for full 100m reach and reliable 10GbE links.
