Network card MicroConnect MC-PCIEX1-82574 PCIe x1 Intel Gigabit Ethernet

MicroConnect MC-PCIEX1-82574 PCIe x1 Intel Gigabit Ethernet is a single-port PCI Express network card designed to add a reliable wired Gigabit LAN interface to desktop PCs and workstations. Based on an Intel Gigabit Ethernet controller, this card supports 10/100/1000 Mbps Ethernet speeds and fits into a PCIe x1 slot to provide stable, low-latency wired connectivity for typical home, office, and light server environments.

Advantages

The card delivers wired Gigabit performance with broad operating system compatibility and proven Intel chipset reliability. Its PCIe x1 form factor allows installation in systems with limited expansion slots while maintaining full Gigabit throughput on a single port. The controller includes hardware-level features for efficient packet processing, reducing CPU overhead and improving network responsiveness for transfers, VoIP, and online collaboration.

Suitable for

• Adding a wired Gigabit LAN port to a desktop PC or workstation
• Replacing a faulty or outdated onboard Ethernet adapter
• Small office or home networking where stable wired connections are required
• Use cases requiring low latency and reliable throughput such as VoIP and file transfers

Key specifications

• Interface: PCI Express x1
• Network speed: 10/100/1000 Mbps (Gigabit Ethernet)
• Ports: 1 × RJ-45 Gigabit Ethernet
• Chipset: Intel Gigabit Ethernet controller
• Supported features: hardware offload for checksums and segmentation, full/half duplex, auto-negotiation
• Form factor: low-profile compatible bracket possible (depends on package contents)

How to use

Power off and unplug the PC before installing the card. Open the computer case, locate an available PCIe x1 slot, and insert the card firmly until it seats in the slot. Secure the bracket to the chassis and close the case. Connect an Ethernet cable to the RJ-45 port and restore power. Install drivers if the operating system does not automatically configure the adapter; obtain drivers from the system manufacturer or Intel if required. After installation, verify link status and network settings in the operating system network control panel.

Recommendations

Use a quality Cat5e or Cat6 cable for reliable Gigabit speeds and keep firmware/drivers up to date for optimal compatibility and performance. When installing in compact systems, check for physical clearance and use a low-profile bracket if available to ensure proper fit.
