This article covers ASUS XG-C100C PCI-Eネットワークインターフェースカード.

Overview

ASUS XG-C100C is a PCI Express 3.0 x4 network card that delivers 10Gbps wired LAN connectivity. With up to 10GbE bandwidth, it dramatically accelerates large file transfers, NAS access, and creative workflows. Supporting 10GBASE-T as well as 5G/2.5G/1G/100M multi-gigabit standards, it works seamlessly with existing network equipment. Powered by the Aquantia AQC107 controller, the XG-C100C is compatible with Windows, Linux, and macOS. It features a single RJ-45 port and requires Cat6A or better cabling to achieve full 10GbE performance. If you have a spare PCIe 3.0 x4 (or larger) slot, this card is an excellent upgrade for your desktop PC or workstation.

Connectivity & Compatibility

The card uses a PCI Express 3.0 x4 interface and can be physically installed in x8 or x16 slots. Auto-negotiation allows it to fall back to 1000BASE-T or slower speeds when connected to legacy switches and routers. To achieve 10Gbps, both the card and network partner (switch or PC) must support 10GBASE-T. Compatible operating systems include Windows 10/11, Linux kernel 5.0+, and macOS High Sierra and newer. Drivers are available from the ASUS support website. In some motherboard BIOS configurations, setting the PCIe link speed to Gen3 manually may improve stability. The card ships with a low-profile bracket included.

Product Info

ASUS XG-C100C has been on the market since around 2020 and remains widely available. Priced around ¥19,000 (approx. $130 USD) on , it sits in the mid-range tier for 10GbE adapters. The package includes a low-profile bracket (standard bracket pre-installed), quick-start guide, and driver disc. The warranty period is three years from the manufacturer. It occupies a sweet spot as an entry-level 10GbE solution for home and SOHO users. Unlike SFP+ based alternatives, the XG-C100C uses standard RJ-45 copper cabling, making it easy to integrate into existing structured wiring.

Best Use Cases

Creative professionals transferring large files (RAW photos, 4K video) between NAS and workstation: 10Gbps cuts transfer times from minutes to seconds. Home users with a 10GbE switch who want high-speed connectivity between multiple PCs: ideal for media servers and backup targets. * Gamers looking to reduce game download and update times: useful, though the impact on in-game latency is minimal compared to upgrading the internet connection.
