This article covers YuanLey 10G PCIe SFP ネットワークカード 10Gb イーサネットカード Realtek RTL8127AT Conrtoller PCIe 10Gb SFP ポート イーサネットアダプター NIC PCI Express X1.

Overview

The YuanLey 10G PCIe SFP network card is an affordable way to add 10 Gigabit Ethernet connectivity to your desktop PC, NAS, or workstation. Powered by the Realtek RTL8127AT controller, it utilizes a PCI Express 4.0 x1 interface while maintaining backward compatibility with PCIe 3.0/2.0 x4/x8/x16 slots. With a data transfer rate of 10 Gbps, it significantly accelerates large file transfers, backups, and low-latency gaming scenarios. The card features an SFP port that works with existing Cat5e/Cat6/Cat6A/Cat7 copper cables via an appropriate SFP+ module.
The package includes both full-height and low-profile brackets, making it suitable for standard tower cases as well as compact or rackmount systems. Additionally, Wake-on-LAN (WOL) support allows remote power-on, which is useful for home lab and server management.

Connectivity & Compatibility

The interface is PCI Express 4.0 x1, but the card can be installed in any PCIe x4, x8, or x16 slot, giving you flexibility regardless of the slot size. For network connectivity, the SFP port supports 10GBASE-SR/LR optical modules, and 10GBASE-T copper connectivity when using an SFP+ to RJ45 transceiver. The card auto-negotiates between 10 Gbps and 1 Gbps. It is compatible with Cat5e or higher Ethernet cables for distances up to 100 meters. On the software side, drivers are available for Windows 11 and Linux (kernel up to 6.12), with official Realtek driver support. macOS compatibility is not officially stated.

Product Info

Positioned as an entry-level to mid-range 10GbE NIC, the YuanLey card uses a Realtek controller to keep costs low compared to Intel or Broadcom alternatives. The warranty is described as "lifetime technical support", but you should check with the seller for precise terms. Included in the box are only the full-height and low-profile brackets; you will need to purchase the SFP+ module and an Ethernet cable separately. The card is primarily sold through online retailers like with a reference price of ¥11,278 (tax included).

Best Use Cases

  • Home lab and NAS users: If your internal network routinely moves large datasets (e.g., 4K video edits, virtual machine images), upgrading to 10GbE with this card eliminates the gigabit bottleneck without breaking the bank.
  • Gamers and streamers: For those who host game servers or need ultra-low latency for local multiplayer/cloud gaming, the 10 Gbps link reduces network jitter and speeds up data transfers.
  • Compact system builders: The included low-profile bracket makes this a viable option for HTPCs, SFF workstations, or rackmount servers where space is at a premium.
  • Who should skip: If your network infrastructure (switch, NAS) doesn't support 10GbE, or if you only need standard 1 Gbps internet, this card is overkill. Also, if you rely on advanced enterprise features like SR-IOV or DPDK, the Realtek chipset may fall short compared to Intel's X710 series.
