The LinksTek X520-DA2 is a dual-port 10GbE SFP+ fiber network interface card powered by the Intel 82599ES controller. It connects via PCI Express 2.0 x8 and brings 10-gigabit bandwidth to servers and desktop PCs. This NIC is designed for data center SAN connectivity, high-speed NAS access, 4K video streaming, and gaming LAN performance. It supports both 10GbE and 1GbE when using SFP+ transceivers, and 10GbE only with direct-attach copper (DAC) cables.
Host interface: PCI Express 2.0 x8 (works in x8 or x16 slots)  Network ports: 2x SFP+ cages (fiber transceiver or DAC cable)  Supported data rates: 10GbE / 1GbE (with SFP+ transceiver), 10GbE (with DAC cable)  OS support: Windows Server 2022/2019/2016/2012R2/2012, Windows 11/10/8. x/7 (32/64-bit), Linux (ixgbe driver: RHEL 8.0-8.8/9.0-9.2/9.3-9.4, SLES 15 SP4 and earlier/12 SP5/12 SP4 and earlier, Ubuntu 22.04/20.04, Debian 11), FreeBSD 13.1-13.2/12.0-12.3/14.0-13.3 * Brackets: Full-height (pre-installed), low-profile (included)

## Product Info
The LinksTek X520-DA2 is a mid-range 10GbE NIC built around the proven Intel 82599ES chipset. Check the retailer's page for the latest price.
Home lab enthusiasts: If you run a NAS or virtualization server at home and want 10GbE on a budget, this card delivers stable Intel-chipset performance. It pairs well with common SFP+ switches. Content creators / video editors: Editing 4K or 8K footage directly from a NAS becomes much faster with 10GbE. Just remember you'll also need a compatible switch and transceivers. * Gamers with local servers: For LAN parties or transferring game installs across a home server, 10GbE speeds up local transfers significantly. However, typical internet connections won't benefit from 10GbE for online gaming.
You need a free PCIe x8 or x16 slot. A x4 slot will bottleneck the card and prevent full 10GbE throughput. SFP+ transceivers or DAC cables are sold separately. Make sure to buy the correct type (e. g. , 10GBASE-SR for multimode fiber). Driver installation is required. Windows may not auto-install the correct driver; download the latest ixgbe driver from Intel's website. Heat management matters. 10GbE NICs run hot during operation. Install in a case with good airflow or consider a model with a larger heatsink.
Q: Can this card connect to a 1GbE switch? A: Yes, if you use a 1GbE-compatible SFP+ transceiver. DAC cables are 10GbE-only, so for 1GbE you'll need an optical module. Q: Does it work with Windows 11? A: Yes, Windows 11 (32/64-bit) is supported. We recommend downloading the latest ixgbe driver from Intel's official site for best compatibility. Q: Will this card improve online gaming latency? A: Not directly — your internet connection speed is the bottleneck for online play. However, if you have a 10GbE local network (NAS, game server), it can speed up game installs and map transfers within your home.
