Four-port Gigabit PCIe adapter

This StarTech.com ST1000SPEX43 card adds four Gigabit Ethernet ports to a client, server or workstation through a single PCI Express x4 slot. It operates at 10, 100 or 1000 Mbps and complies with IEEE 802.3, 802.3u and 802.3ab standards. The half-height form factor measures 0.70 by 4.70 by 5.40 inches and weighs 0.22 lb.

Suits systems needing multiple wired links

Builders who need four copper Gigabit connections from one expansion slot will find this adapter a direct fit. It supports twisted-pair cabling up to 100 metres and functions in temperatures from 0 to 55 degrees Celsius. Systems without a free PCIe x4 slot or that require fibre connectors cannot use this card.

PCI Express x4 interface required

The card connects through a PCIe x4 male edge connector and delivers 2000 MB/s of bus bandwidth. A compatible x4 slot is the single specification that determines whether the adapter will install and operate at full throughput.

Questions about this item

Does the card come with cables or brackets, or do I need to buy them separately?

The package contains only the 4-port PCIe Gigabit network card itself. Ethernet cables and any mounting brackets are not included and must be purchased separately.

My motherboard has PCIe x4 and x8 slots — which one should I use for this ST1000SPEX43?

The adapter uses a PCI Express x4 male connector and is designed for a PCIe x4 slot. It will also work in a larger x8 or x16 slot running at x4 electrical width.

What real-world throughput can I expect from the 2000 MB/s PCIe x4 interface on this card?

The PCIe x4 link provides 2000 MB/s of bus bandwidth, while each of the four ports delivers up to 1000 Mbps Ethernet throughput over twisted-pair cable up to 100 metres.
