Vszerda 2.5Gbps PCIe 1x network card

This Vszerda network card adds a 2.5Gbps Ethernet port to a desktop motherboard through a PCIe 1x slot. It fits x1, x4, x8 and x16 PCI Express slots but will not work in legacy PCI slots. Both a low-profile bracket and a standard bracket are included for flexible installation. The Realtek RTL8125B controller handles the connection.

PCIe 1x to RJ45 interface

The card connects through a single PCIe 1x lane and presents one RJ45 port. It supports auto-negotiation at 2.5Gbps, 1Gbps, 100M and 10M speeds. Standard Cat5e or better UTP cable runs up to 100 metres. Supported standards include IEEE 802.3bz, IEEE 802.3x flow control, IEEE 802.1Q VLAN tagging and IEEE 802.1P priority encoding. PXE boot and Auto MDIX are also available.

2.5Gbps throughput headroom

The adapter delivers up to 2.5Gbps bandwidth, roughly 2.5 times traditional gigabit rates. This headroom handles swift file transfers, HD video streaming and lag-free online gaming comfortably. Performance drops back to 1Gbps or lower when the switch or cabling cannot sustain 2.5Gbps. Driver support covers Windows 11, Windows 10 and Linux for PC, server, workstation or NAS use.

Questions about this item

What does the 2.5Gbps headline speed actually deliver inside a desktop PC?

The Realtek RTL8125B chip provides up to 2.5Gbps throughput over Cat5e or better UTP cable at distances up to 100m, with auto-negotiation down to 1Gbps, 100M or 10M.

Which PCIe standard and lane width does the card use, and what does that limit in practice?

It uses a PCIe 1x interface that fits x1, x4, x8 or x16 slots; the single lane caps theoretical bandwidth to the 2.5Gbps line rate.

What physical space and brackets are needed to mount the card?

The board measures 11cm x 11cm x 1cm and ships with both low-profile and standard brackets for flexible installation.
