Four 2.5 Gbps Ports on PCIe

This Grwibeou network card adds four RJ45 ports to a desktop through a PCI-Express slot. Each port negotiates speeds of 10, 100, 1000 Mbps or 2.5 Gbps and supports Wake On LAN. A metal heatsink keeps the controller cool for stable long-term operation. The card targets users who need multiple high-speed wired links from a single expansion slot.

Suits Multi-Link Servers Not Single-Port Upgrades

The adapter fits builders running ESXi, diskless workstations or PXE boot environments that require several 2.5 Gbps connections. It also serves homes upgrading from 1 Gbps without rewiring to 10 Gbps cabling. Buyers who only need one extra Ethernet port or who lack a free PCIe slot should consider a simpler single-port card instead.

Check Slot Width And Driver Support

Verify the motherboard has an open PCIe x4 or wider slot; the card uses a thickened x4 gold finger for reliable contact. Confirm the operating system or hypervisor includes drivers for the 2.5G controller and that the PCIe generation meets the 2.1 specification. Ensure the chassis provides enough airflow for the passive heatsink to dissipate heat effectively.

Questions about this item

Does my motherboard need a PCIe x4 slot for the 4-port 2.5Gbps card to run at full speed?

Yes, the card uses a PCIe x4 gold-finger connector, so a physical x4 or wider slot is required to expose all four 2.5Gbps ports.

Will the card negotiate down to 1Gbps on my existing Cat5e patch panel?

Yes, each RJ45 port auto-negotiates at 10, 100, 1000 or 2.5Gbps, so Cat5e links will settle at 1Gbps without configuration.

How can I verify all four ports are active at 2.5Gbps after installation?

Check the OS network adapter list or switch port LEDs; each port should report a 2.5Gbps link speed when connected to a 2.5Gbps-capable switch.
