Learn about Network Interface Cards (NICs)
Faster, More Reliable Wired Connectivity
A Network Interface Card gives your PC or server a fast, stable link to your network. From budget 1GbE to multi-gig (2.5GbE/5GbE) and 10GbE+, you’ll find PCI Express cards, USB adapters, and multi-port models in Newegg’s Network Interface Cards catalog. Pair your NIC with the right switch, optics, and cabling to unlock consistent throughput for gaming, low-latency streaming, content creation, virtualization, iSCSI backups, and more.
Popular NIC Categories
PCIe Ethernet Cards
The go-to choice for desktops and workstations. Options range from 1GbE and 2.5GbE to 10GbE/25GbE, with features like VLAN tagging, link aggregation (LACP), checksum/TSO/LRO offload, SR-IOV/RDMA, and PXE/Wake-on-LAN. Browse performance picks here: 10GbE network cards.
USB & USB-C Ethernet Adapters
Ideal for ultrabooks and mini PCs—plug-and-play wired networking without opening the case. Choose USB 3.0/USB-C for Gigabit and above. Find compact options in Network Adapters & Ethernet Connectors.
Fiber & SFP/SFP+ NICs
Use SFP/SFP+ for long-distance or electrically isolated runs and ultra-low latency. Pair your card with compatible optics from SFP/SFP+ transceivers and OM3/OM4 fiber for 10GbE and higher.
Key Decisions Before You Buy
Match the NIC to your target speed (1G, 2.5G, 5G, 10G, 25G), PCIe slot type (x1/x4/x8, Gen3/Gen4), and connector (RJ45 vs. SFP/SFP+). For fiber or long-run links, compare SFP+ fiber NICs. For copper installs, use the right cabling—see Ethernet cables (Cat6/Cat6a). If you’re wiring racks or tight spaces, confirm low-profile/half-height brackets and plan mounting with server racks & cabinets.
Performance tip: For 2.5GbE/5GbE over copper, Cat6/Cat6a reduces errors and heat. For 10GbE+ fiber, verify SR/LR optics and OM3/OM4 cable type. Power users should also check driver support for Windows, Linux, or VMware ESXi.
Typical Use Cases
Home & Gaming: Upgrade to a 2.5GbE PCIe card for faster downloads and smoother game/stream concurrency; pair with a 2.5G switch.
Creative & NAS: Move large media quickly with 10GbE PCIe NICs; use SFP+ for fiber runs to a rack or studio bay.
Virtualization & Labs: Choose dual-port/quad-port server NICs for VLANs, LACP, SR-IOV, and traffic isolation across hosts and services.
Why Add a Dedicated NIC?
Boosts wired speed and stability beyond onboard LAN, enables VLAN isolation and link aggregation, reduces CPU usage via hardware offloads, and adds flexibility for SFP/SFP+ fiber runs or multi-port redundancy and failover.
Frequently Asked Questions
Do I need 2.5GbE or is 1GbE enough?
1GbE is fine for basic browsing and streaming. If you copy large files, use fast NAS, or share bandwidth among many devices, 2.5GbE offers a noticeable speed boost—pair it with a compatible 2.5G switch.
RJ45 vs. SFP/SFP+ — which should I choose?
RJ45 over copper is convenient for short runs and existing cabling. SFP/SFP+ with fiber is better for long distances, lower latency, or electrical isolation. If you go fiber, match your card with the right optics from SFP/SFP+ transceivers.
Will a USB Ethernet adapter bottleneck my laptop?
Use USB 3.0 or USB-C models for Gigabit or faster speeds. They’re great for travel and thin-and-light PCs—browse options in Network Adapters & Ethernet Connectors.
