Green PCB network card with two RJ45 ports and low-profile bracket

Vszerda

Vszerda Dual Port 2.5Gbps PCIe x1 Network Card

SKU CH-KPR1-8DX9W

Adds two 2.5 Gbps RJ45 ports via a PCIe x1 slot, supporting VLAN tagging, flow control and low-profile brackets

  • Dimensions11 cm x 11 cm x 1 cm
  • Add two 2.5Gbps Ethernet ports via a single PCIe x1 slot
  • 5 times faster throughput than standard gigabit connections
  • Fits x1, x4, x8 and x16 PCI Express slots
  • Includes low-profile and full-height brackets for any case
  • Supports PXE boot, VLAN tagging and 802.3x flow control

Dual-Port 2.5Gbps PCIe x1 Adapter

The Vszerda network card adds two RJ45 ports to a desktop through a single PCI Express x1 slot. It supports 2.5GBASE-T speeds up to 2.5 times faster than standard gigabit Ethernet. The board fits x1, x4, x8 or x16 slots and includes both low-profile and full-height brackets.

Suits owners needing extra wired ports

This card suits owners who need additional wired ports or a replacement for a failed onboard interface. It works with standard desktop motherboards that have a free PCI Express slot. Builders who require fibre connectivity, 10GbE speeds or a PCI legacy slot should look at other solutions.

Handles 2.5Gbps links with VLAN and PXE

Each port delivers 2.5Gbps full-duplex throughput with IEEE 802.3x flow control and 802.1Q VLAN tagging. PXE boot and Auto MDIX are supported for diskless deployments and automatic crossover detection. The adapter tops out at 2.5Gbps, so aggregates beyond 5Gbps or 10GbE uplinks exceed its headroom.

Questions about this item

What slot must my motherboard have free to install this PCIe x1 dual-port 2.5Gbps card?

Any PCI Express slot — x1, x4, x8 or x16 — will accept the card; it does not fit legacy PCI slots.

Will my existing Cat 5e cables limit the 2500Mbps ports to 1000Mbps?

Cat 5e supports 2.5GBASE-T up to 100 m, so the 2500Mbps links will run at full speed with the cables you already own.

How can I confirm both RJ45 ports are negotiating 2.5Gbps after driver installation?

Check the adapter properties in Device Manager or run ethtool on Linux; each port should report 2500Mbps full duplex with IEEE 802.3bz active.
