PC Expansion & Connectivity

PCIe Wi-Fi, audio, capture and other expansion options for desktop PCs.

Quick buying guide

A practical starting point for pc expansion & connectivity

Typical UK price range: About £25–£250+ depending on Wi-Fi, audio, capture or high-speed I/O requirementsIndicative market guide reviewed August 2026. International pricing, tax, availability and subscriptions vary by region.

Only add an expansion card when the motherboard does not already provide the required feature. Check physical slot size, electrical lane availability, motherboard headers, BIOS requirements, driver support and whether installing the card disables or shares bandwidth with M.2 or other PCIe devices. For business and lab systems, also plan network speed, switch/NAS capability and redundancy rather than buying a faster NIC in isolation.
