SMUGDESK PCIe x1 5Gbps RJ45 Network Card

PCIe 5.0 5 Gbps wired NIC

This SMUGDESK network card upgrades desktop PCs, workstations and small servers with a 5.0 Gbps RJ45 connection. It plugs into any PCIe x1, x4, x8 or x16 slot on ATX, MATX or ITX motherboards without using a graphics-card lane. A built-in controller chip delivers stable throughput with low heat and low power draw. The full-height metal bracket provides EMC shielding for reliable long-term operation.

Practical limits of PCIe x1 at 5 Gbps

The card uses a single PCIe x1 lane, so total bandwidth cannot exceed the electrical limit of that link even though the controller supports 5.0 Gbps. Real-world throughput depends on cable quality, switch or router port speed and the host system's ability to sustain continuous transfers. Copper RJ45 cabling must meet the required category rating to achieve the advertised rate. Latency improvements assume the rest of the network path is not a bottleneck.

Replaces standard 1 Gbps adapters

This card replaces ordinary gigabit NICs when moving massive folders, RAW video files or disk-array backups that saturate a 1 Gbps link. The jump is worth it for users who regularly hit the ceiling of a standard gigabit connection and need consistently higher sustained speeds. It is not for builders who need multi-port aggregation, fibre connectivity or speeds beyond 5 Gbps.
