IOCrest 6 Port 2.5 Gigabit PCI-e x4 Ethernet Network Card Realtek RTL 8125B

SKU CH-TMZG-BATSX

Adds six 2.5 Gbps Ethernet ports through a single PCIe x4 slot using Realtek RTL 8125B controllers

  • Class2.5G Ethernet Port
  • Six ports deliver 2.5 Gbps each for high-density throughput
  • Realtek RTL 8125B chipset provides stable 2.5 Gigabit connectivity
  • PCIe x4 host interface supplies bandwidth for six concurrent ports
  • Supports Windows and Linux for broad operating-system coverage
  • Multi-port design simplifies cabling in servers or workstations

Six-port 2.5 Gigabit adapter

This PCI Express x4 network card adds six 2.5 Gigabit Ethernet ports to a desktop or server. The Realtek RTL 8125B chipset drives each port at 2.5 Gbps for faster file transfers and lower latency. It targets users who need multiple high-speed wired links in a single slot.

Suits multi-port aggregation.

Builders aggregating several 2.5 Gbps connections for NAS, virtualisation or camera networks will use all six ports. Buyers who only need one 2.5 Gbps link or who lack a free x4 slot should look at a single-port alternative.

PCI Express x4 host interface

The card requires an open PCIe x4 slot (or a larger slot wired for x4) to deliver full bandwidth across all six ports. Without that slot width the adapter cannot operate at its rated 2.5 Gbps per port.

Highlights

  • Six ports deliver 2.5 Gbps each for high-density throughput
  • Realtek RTL 8125B chipset provides stable 2.5 Gigabit connectivity
  • PCIe x4 host interface supplies bandwidth for six concurrent ports
  • Supports Windows and Linux for broad operating-system coverage
  • Multi-port design simplifies cabling in servers or workstations

Questions about this item

What maintenance or replacement does the Realtek RTL 8125B controller need over its service life?

The controller has no moving parts and requires no scheduled maintenance; replacement is only necessary if the card itself fails.

What limit appears first when all six 2.5 Gbps ports run at full load?

The PCIe x4 host interface caps combined throughput at the lane bandwidth, so the bus becomes the bottleneck before the individual ports saturate.

How much heat and fan noise does the card produce when running all day?

The card is passively cooled with no fan, so it generates no fan noise; heat output is limited to the Realtek RTL 8125B chipset and PCB under sustained load.
