Network card Zyxel XGN100C v3 10G RJ45 PCIe network card

The network card Zyxel XGN100C v3 10G RJ45 PCIe is an internal PCIe 10 Gigabit Ethernet card, aimed at more serious desktop and work machines – from enthusiasts to small servers and NAS. Its main idea is simple: to bring up to 10 000 Mbps wired connection through a standard RJ-45 port into systems with a PCIe slot. It works as a Multi-Gigabit solution – from 100 Mbps to 10G – and thus adapts to your current network, without locking you into a 10G scenario only. It uses the proven Marvell/Aquantia AQtion AQC107 chipset and passive heatsink for silent cooling.

What you get

With LAN port 1 x 10/5/2.5/1 Gbps/100 Mbps RJ-45, you can connect the card to a standard 10GBASE-T switch or router, without the need for optics or special connectors. Multi-Gig support (10G/5G/2.5G/1G/100M) means that if you currently have only 2.5G or 5G infrastructure, the card will simply drop to the corresponding speed and still fully utilize its capacity. Jumbo frame up to 16 KB and built-in QoS help with heavy file transfers, backups, and working with large projects over the network, reducing overhead and improving smoothness. VLAN tagging allows you to separate traffic – for example, separate networks for work, guests, or virtual machines – directly at the card level. Thanks to Wake-on-LAN (WoL), you can wake the machine remotely for night backups or remote access, and Energy Efficient Ethernet (802.3az) helps not to raise consumption unnecessarily in idle.

• Support for transfer speed up to 10 000 Mbps, suitable for 10G local networks, heavy backups, and fast access to NAS or server.
• PCI Express interface requiring PCIe Gen-3 (or 2) x4 slot, so there is enough bus for the full capacity of the 10G connection.
• Multi-Gig LAN architecture 10G/5G/2.5G/1G/100M Ethernet over twisted pair (10GBASE-T), allowing you to use standard copper cable and different speeds according to the switch.
• Chipset Marvell/Aquantia AQtion AQC107, well-known in desktop and small server environments for stable 10G RJ-45 connectivity.
• Network functions like Jumbo frame up to 16 KB, built-in QoS, VLAN tagging, and Wake-on-LAN (WoL), which help for better control and efficiency of traffic.
• Form factor internal PCIe add-in card with included full-height and low-profile brackets, so it fits both standard and compact cases.
• Compatibility with Windows 7/8.0/8.1/10, Windows Server 2012, and Linux kernels 3.10–4.4, covering a wide range of desktop and server distributions.
• Passive cooling heatsink and weight around 78–82 g, ensuring silent operation without additional moving parts.

Who it's suitable for

It's suitable if you want to upgrade your home or office network to 10G – for fast access to NAS, working on large media projects, virtual machines, or backup servers. It's also a good choice for a gaming/streaming machine if you have Multi-Gig internet or internal network and want minimal LAN limitations. It's not the most logical choice if you only use a 1G router and have no plan to move to higher speeds in the near future.

The most sensible thing here is the combination of 10GBASE-T through PCIe x4, Multi-Gig flexibility, and "server" extras like Jumbo frame, QoS, and VLAN in a convenient desktop form factor. You install it, plug in the cable, and you're ready for a fast wired network without exotic hardware.
