PCI/PCI-E Add in Cards

These cards slot into various ports on a motherboard or laptop. Their purpose is to offer features that are not present otherwise, such as networking, USB, Thunderbolt, and WiFi support. These cards typically fit into a spare PCI or PCIe slot on a desktop motherboard or to a dedicated I/O port on a laptop, and they provide an easy way to upgrade the system without having to switch out the motherboard and CPU.

RJ45 Network Cards

Network cards are added to desktop PCs, workstations or servers to enable connectivity to other users, devices and the outside world. RJ45 is the common wired interface used to connect via Ethernet to network switches and routers.


SFP+ Network Cards

Network cards are added to servers to enable connectivity to other users and devices in a high performance environment. SFP+ is a small form factor pluggable interface allows fibre optic cabling to be used as opposed to Ethernet offering greater speeds, distance and low latency when connecting to network switches.


Wireless Adapters - PCI / PCI-E / M.2

These wireless network cards fit inside a computer (PC / notebook / Laptop) and connect using either the PCI, PCIe, M.2, Mini-PCIe interface. These Wireless Adaptors allow the computer to connect to a wireless network without having to run a network cable to the system. Advanced features such as high bandwidth and encryption ensure both a fast and secure connection to a WiFi network. Always check your motherboards interface for PCI or PCIe to ensure you select the correct wireless network card adaptor for your requirements.
