Overview
The ASUS XG-C100C is a PCI Express network adapter designed to add high-speed wired Ethernet connectivity to compatible desktop computers and workstations. It supports data rates up to 10Gbps over a standard RJ45 copper Ethernet connection, making it suitable for high-speed file transfers, network-attached storage (NAS), workstation networking, and bandwidth-intensive workloads.
The adapter supports five Ethernet speeds: 10Gbps, 5Gbps, 2.5Gbps, 1Gbps, and 100Mbps. This multigigabit compatibility allows integration with supported network switches and routers operating at different link speeds. Built-in Quality of Service (QoS) and IEEE 802.1p traffic prioritization help prioritize supported network traffic.
The XG-C100C uses a PCIe interface and supports Windows and Linux configurations subject to hardware revision and driver availability. Its RJ45 port allows use of compatible copper Ethernet cabling without requiring a fiber-optic connection.

Product Note
The XG-C100C is a wired network adapter, not a router or switch. Achieving 10Gbps requires compatible networking equipment, a suitable PCIe slot, appropriate drivers, and cabling that supports the required speed and distance. ASUS reports 10Gbps operation over Cat5e cable within 30 metres under its test conditions; Cat6a is a practical choice for many 10GbE installations.
Hardware revisions differ in PCIe lane requirements and operating-system support. Confirm whether the supplied card is V1, V2, or V3 and check the corresponding ASUS specifications before deployment. Actual throughput depends on the host system, network configuration, and connected equipment.
Frequently Asked Questions
What is the maximum speed of the ASUS XG-C100C?
