RTL8127 10Gbps PCIe Ethernet Network Card RJ45 Port LAN NIC Desktop Adapter NASProduct Description
Tired of 1Gbps network bottlenecks, laggy connections and slow file transfers between your PC and NAS?
Upgrade your desktop, gaming PC, media workstation or private NAS server to blazing-fast 10G wired networking with this PCIe x4 Ethernet Card. Built around the reliable Realtek RTL8127 chip, this single RJ45 LAN adapter delivers exceptional throughput, reduces packet loss and drastically speeds up transfers for large RAW video files, game libraries and bulk backups. Featuring a full aluminum heatsink and an included low-profile bracket, it fits standard ATX towers as well as compact Mini-ITX small form-factor cases.
Product Features
1. 10Gbps Ultra-Fast Auto-Negotiation
This card automatically negotiates speeds: 10G / 5G / 2.5G / 1G / 100Mbps to match your network hardware.
It delivers far faster transfer performance than regular 5G Ethernet adapters, saving tons of time on NAS backups and 4K/8K media file transfers. At full 10Gbps load, it only draws 1.79W power, balancing top-tier
speed and low power consumption.
2. Stable Connection, Low Latency & Minimal Packet Loss
Refined hardware circuitry cuts down packet loss and reduces network latency.
Enjoy a steady wired link free from stutters or random drops. Perfect for competitive gaming, real-time server sync and long-running 24/7 NAS storage tasks.
3. Full Aluminum Heatsink for Effective Heat Dissipation
The stacked aluminum alloy heatsink fully covers the main chip, quickly drawing away heat generated during heavy data transmission. It prevents thermal throttling under continuous full-load operation to maintain consistent, reliable network performance.
4. Easy Installation & Great Windows Compatibility
Comes with driver support, fully optimized for Windows 10 / Windows 11 64-bit.
Quick setup: power off your PC, insert the card into an available PCIe slot, install the proper driver, and you’re ready. Most motherboards require no complex BIOS tweaks.

1 × 10G PCIe RJ45 Ethernet Network Card
1 × Low-Profile Short Bracket
Notes
1. Cat6a / Cat7 shielded Ethernet cable and a 10G-capable switch/router are required to reach full 10Gbps speed. Cat5e cable only supports up to 2.5G.
2. Install this card into PCIe X4, X8 or X16 motherboard slots. PCIe X1 slots cannot sustain full 10G bandwidth.
3. Install the official driver after hardware installation to unlock complete 10G functionality.
