This article covers Intel EXPI9404PTLBLK-1PK PRO.

Overview

The Intel EXPI9404PTLBLK-1PK is a quad-port Gigabit Ethernet NIC built around the Intel PRO/1000 PT (82571EB) controller. It connects via PCIe Gen 1.0 x4 and ships with both low-profile and full-height brackets, allowing installation in everything from 1U rackmount servers to standard tower cases. Each of the four RJ45 ports supports 10/100/1000 Mbps auto-negotiation and jumbo frames. While it's an older design, its proven Intel chipset and low power consumption (around 5W) make it a reliable choice for multi-port networking in servers, NAS appliances, and routers. It remains available new and used on online retailers, offering excellent value for Gigabit networking.

Connectivity & Compatibility

This NIC uses a PCIe Gen 1.0 x4 interface and fits into any PCIe x4, x8, or x16 slot. The included brackets enable use in both standard ATX cases and low-profile 1U/2U enclosures. It is compatible with a wide range of operating systems including Windows Server (2003 through 2019), Linux (kernel 2.6+), FreeBSD, and VMware ESXi. All four ports support 10/100/1000 Mbps auto-negotiation and jumbo frames up to 9000 bytes. Intel PROSet utility enables teaming (link aggregation) and VLAN configuration.

Product Info

The Intel EXPI9404PTLBLK-1PK is an OEM quad-port NIC featuring the Intel PRO/1000 PT controller. It was originally released in the late 2000s but remains available through retailers like online retailers. Pricing is around ¥27,000 (~$180 USD). The package includes low-profile and full-height brackets plus a quick-start guide. Warranty is handled by the seller since it's an OEM product. This card sits in the entry-to-mid-range segment, offering stable multi-port Gigabit connectivity at a reasonable cost. For environments where 1GbE is sufficient, it's a cost-effective alternative to newer 10GbE adapters.

Best Use Cases

  • Home server and NAS builders who need to separate LAN, WAN, and iSCSI traffic. Four ports allow flexible network segmentation without buying a managed switch. The Intel chipset's stability is ideal for 24/7 operation.
  • Virtualization enthusiasts running VMware ESXi, Hyper-V, or Proxmox. Intel NICs are well-supported and offer reliable SR-IOV and VLAN capabilities. However, note the PCIe Gen 1.0 x4 bandwidth limit (~1 GB/s total) when saturating all ports simultaneously.
  • Budget-conscious users who require multiple Gigabit ports but don't need 10GbE speeds. This card provides four ports for a fraction of the cost of newer 10GbE adapters. Its low power draw also reduces cooling requirements in dense server environments. Not suitable for those needing 2.5GbE or faster.
