Syba 4-Port 2.5G Ethernet PCIe 2.0 x4 Expansion Card with Low Profile Bracket

SKU CH-V3Z8-0BHA0

Adds four 2.5 GbE RJ45 ports via PCIe 2.0 x4 using Intel i225, supports VLAN tagging and Wake-on-LAN, includes low-profile bracket

  • TypePCI Express Controller Card
  • Adds four 2.5 GbE ports via a single PCIe 2.0 x4 slot
  • Intel i225 controller drives 10/100/1000/25000 Mbps speeds
  • Low-profile 8 cm bracket fits compact HTPC or server cases
  • Wake-on-LAN and 802.1Q VLAN tagging supported out of the box
  • Broad OS support from Windows 98 SE through Windows 10 and Linux

Four-Port 2.5 Gigabit Ethernet Adapter

This PCI Express 2.0 x4 card adds four RJ45 ports, each capable of 10, 100, 1000 or 25000 Mbps speeds, to a desktop or server. It uses the Intel i225 chipset and fits any x4, x8 or x16 slot. A standard 12 cm bracket and an extra 8 cm low-profile bracket are included for small-form-factor cases.

Suited For Multi-Port 2.5G Networking

Builders who need several 2.5 Gigabit links for NAS access, virtualisation or isolated VLANs will find the quad-port layout useful. The card supports Wake-On-LAN and 802.1Q VLAN tagging. It is not suitable for systems that lack a free PCIe x4 or larger slot, or for users who only require a single 1 Gigabit connection.

PCIe 2.0 x4 Interface Determines Compatibility

The card requires an available PCI Express 2.0 x4, x8 or x16 slot and negotiates at up to 2.5 Gigabit per port. Driver support covers Windows 10, 8.1, 7, Vista, XP, 2000, ME, 98SE and Linux. Verify that the motherboard provides the required slot before purchase.

Questions about this item

Will the Intel i225 chipset on this quad-port card need firmware updates or active cooling replacement over time?

The Intel i225 chipset is a solid-state controller with no moving parts; it does not require firmware updates or cooling-fan replacement during normal operation.

What bandwidth ceiling appears first when all four 2.5 GbE ports run at full load through the PCIe 2.0 x4 interface?

The PCIe 2.0 x4 link provides roughly 20 Gbps of throughput, which exceeds the combined 10 Gbps maximum of the four 2.5 GbE ports, so the Ethernet ports themselves are the limiting factor.

How much heat and noise does the card produce when all four ports sustain 2.5 Gbps traffic continuously?

The passively cooled Intel i225 controller draws modest power and runs silently; no fan noise is generated and case airflow is sufficient to manage the heat.
