10Gbps PCIe 3.0 x2 Network Adapter

The STARTECH ST10GSPEXNB2 is a single-port 10Gbps Ethernet card that plugs into a PCI Express 3.0 x2 slot. It uses the Marvell AQC113CS chipset to deliver multi-gigabit connectivity over standard twisted-pair cabling. The card includes both full-height and low-profile brackets for flexible installation in desktops or servers.

Suited for workstations needing 2.5G.

This adapter suits builders upgrading a PC or server to multi-gigabit LAN speeds using existing Cat5e, Cat6 or Cat6a infrastructure. It is not for systems lacking a free PCIe x2 or larger slot, nor for users who require multiple RJ45 ports, fibre connectivity, or wireless networking.

PCIe 3.0 x2 host interface determines throughput

The card operates at PCI Express 3.0 x2, providing up to 10Gbps line rate when the slot matches that generation. In a PCIe 2.0 slot the maximum speed drops to 5Gbps, so the host interface generation directly decides the achievable network performance.

Highlights

  • 10 Gbps throughput on Cat6 or Cat6a cabling
  • 5 Gbps and 2.5 Gbps speeds over existing Cat5e runs
  • PCIe 3.0 x2 interface with Marvell AQC113CS chipset
  • 16K jumbo frames plus VLAN tagging and PTP support
  • Low-profile bracket included for compact chassis installs

Questions about this item

Will the StarTech ST10GSPEXNB2 fit in a low-profile chassis with the included bracket?

Yes, the box includes a low-profile bracket that swaps onto the card for slim cases; the board itself is .8 inches tall and 4.2 inches wide.

What is the common mistake when installing this PCIe 3.0 x2 adapter?

Inserting it into a PCIe 2.0 slot caps the link at 5 Gbps instead of the full 10 Gbps, so use a 3.0 x2 or wider slot.

Does the Marvell AQC113CS chipset require any firmware updates or replaceable parts over time?

No user-serviceable parts or firmware modules are exposed; the card is a passive plug-in NIC with no batteries or fans to maintain.
