The card's single biggest selling point is its dual Intel X550AT 10GBASE-T ports that deliver up to 10Gb\/s per port while also supporting NBASE-T speeds for 5Gb\/s and 2.5Gb\/s where cabling or switches limit throughput. Installation is straightforward and the adapter includes both low-profile and full-height brackets, making it versatile for compact cases and standard towers alike.\u003c\/p\u003e\n\u003ch2\u003eKey Features\u003c\/h2\u003e\n\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eDual 10G RJ45 ports:\u003c\/strong\u003e Two independent Intel X550AT ports provide full 10Gb\/s copper connectivity for long-distance links to servers or workstations.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMulti-gig support:\u003c\/strong\u003e The card supports 10Gb\/s, 5Gb\/s, 2.5Gb\/s, 1Gb\/s and 100Mb\/s, allowing gradual network upgrades without replacing existing cabling or switches.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePCIe 3.0 x8 interface:\u003c\/strong\u003e Native PCIe v3.0 (8.0GT\/s) x8 connection ensures the card has sufficient bandwidth when used in x8 or x16 slots.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWide OS compatibility:\u003c\/strong\u003e Drivers and kernel support span Windows, multiple Linux distributions, FreeBSD, UEFI and VMware ESXi editions commonly used in labs and servers.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eIncludes mounting options:\u003c\/strong\u003e Both low-profile and full-height brackets are supplied so the adapter fits standard and slim computer or server chassis.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDriver availability and support:\u003c\/strong\u003e Driver CD included and drivers are available from the Intel site, with a 180 day warranty and customer support promise.\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch2\u003eWho It's For\u003c\/h2\u003e\n\u003cp\u003eEnthusiasts building TrueNAS, pfsense, or small virtualization hosts will appreciate the card's reliable Intel controller and multi-gig capability, which improved vMotion times and general throughput for several users.
