This article covers Euqvos PCIe 3.0 x4 サーバーアダプター Intel X550-T2 ELX550AT 10G 2*RJ45 NIC用.

Overview

The Euqvos PCIe 3.0 x4 Server Adapter featuring the Intel X550-T2 ELX550AT controller is a dual-port 10GbE network interface card designed for servers, workstations, and power users who need high-bandwidth connectivity. Each RJ45 port supports speeds up to 10Gbps, making it an excellent choice for upgrading from legacy 1GbE networks. This adapter uses a PCIe 3.0 x4 interface (compatible with x8 and x16 slots) and comes with both low-profile and full-height brackets, ensuring it fits into a wide range of chassis. An alloy heatsink provides passive cooling, keeping the card stable under sustained loads without requiring a fan.

Connectivity & Compatibility

The card is built around the Intel X550-T2 controller, which supports advanced server features including SR-IOV, VMDq, FCoE, PXE, iSCSI, and jumbo frames. It is compatible with a broad range of operating systems: Windows 7/8/10/11, Windows Server 2008 R2 through 2022 Linux (stable kernel 3.x, 2.6.x), Red Hat Enterprise Linux 5/6, SUSE Linux Enterprise Server 10/11 * FreeBSD 9, VMware ESX/ESXi Per-port data rates: 1Gbps, 2.5Gbps, 5Gbps, and 10Gbps. Note that 1Gbps and 10Gbps use auto-negotiation, while 2.5Gbps and 5Gbps require manual speed configuration in Windows or Linux. The card includes both low-profile and full-height brackets in the box.

Product Info

Released around 2022, the Euqvos X550-T2 adapter occupies the mid-to-high-end segment of the 10GbE NIC market. It offers essentially the same feature set as Intel's own X550-T2 but at a more accessible price point. The warranty period varies by seller; purchases through typically include a 1-year manufacturer warranty. Accessories include the NIC itself, low-profile bracket, full-height bracket, and a driver guide.

Best Use Cases

NAS and file server owners: Upgrading to 10GbE dramatically speeds up large file transfers. This card is ideal for anyone running a Synology, QNAP, or custom-built NAS who wants to eliminate network bottlenecks. IT administrators managing virtualized environments: With SR-IOV and VMware ESXi support, you can assign virtual functions directly to VMs, improving performance in hyper-converged or clustered setups. * Creative professionals handling large media files: Video editors and 3D artists working with 4K/8K footage will benefit from the high throughput when accessing network storage. Just remember you'll also need a 10GbE switch or direct connection and Cat6a cabling.

Things to Consider

While the PCIe 3.0 x4 interface provides ample bandwidth (roughly 3.94 GB/s) for dual 10GbE ports, make sure your motherboard has a free PCIe slot that is at least x4 electrically. The card is passively cooled, so adequate case airflow is important — in poorly ventilated server cases, the heatsink may struggle to dissipate heat under continuous full load. Also note that 2.5Gbps and 5Gbps modes require manual configuration; they are not auto-negotiated. If you plan to use those intermediate speeds, be prepared to set them in the driver or OS settings. Finally, this is a server-grade NIC, so driver installation on consumer Windows versions may require manual steps rather than plug-and-play. ## FAQ
Q: Can I use this card in a regular desktop PC? A: Yes, as long as you have a free PCIe x4 or larger slot. You will need to manually install Intel's drivers from their website — Windows Update may not automatically detect it. Q: Do I need a special switch or cable? A: Yes. To achieve 10Gbps speeds, you need a 10GbE-capable switch (or a direct crossover connection) and Cat6a or higher Ethernet cables. Q: How does this compare to other 10GbE cards? A: The key advantage is the Intel X550 controller with full server feature support at a lower price than Intel's own branded cards. The trade-off is passive cooling, which requires good airflow, and the need for manual driver installation on some systems.
