Ubiquiti USW-FLEX-XG | UniFi Switch Flex XG | 41 Gbps Switch
A compact 5-port switch that brings four 10 GbE ports to a desk or wall, powered by whatever PoE+ or USB-C source is already at hand.
Why this one
- Four 10 GbE RJ45 ports in a 135 × 185 mm footprint means you can drop 10G to four devices — NAS, workstation, NVR, uplink — without a full rack switch taking up space.
- 41 Gbps non-blocking throughput means those four 10G ports can all run at line rate simultaneously, so a busy NAS transfer won't choke the workstation sitting next to it.
- Powers from 802.3at PoE+ or a 5V USB-C adapter, so you can tuck it behind a monitor or mount it under a desk without running a separate power cable to the wall.
- Supports up to 1,000 VLANs and a 16,000-entry MAC table, which is more headroom than most compact switches offer and lets it sit inside a segmented network without becoming the bottleneck.
Good fit if you have a desk, editing suite, or server nook where two or more devices need genuine 10G connectivity and you're not ready to justify a full 24-port switch for the job.
Worth considering something else if you need PoE output ports rather than just a PoE input — the Flex XG receives PoE to power itself but does not pass PoE to connected devices, so anything that needs to be powered over the cable will need its own supply.
What you'll also need
A PoE+ source (802.3at) or a 5V/5A USB-C adapter to power the unit, Cat6A cabling to each 10G device to reliably reach 10 GbE speeds, and a UniFi controller running Network version 6.1.67 or later — a UniFi gateway or Cloud Gateway handles that if you don't already have one.
