5-Port Gigabit Desktop Switch

The No Sew GS105U adds five 10/100/1000 Mbps RJ45 ports to a single uplink from your router or modem. It is an unmanaged, plug-and-play device designed for home offices, dorm rooms or media setups that need more wired connections for PCs, consoles or printers. The fanless plastic chassis measures 3.46" × 2.07" × 0.94" and weighs 53 g.

Check Uplink And Power Source

Verify that your router or modem has a spare RJ45 port for the uplink connection. The switch draws 5 V power through a USB-C jack; ensure you have a compatible USB-A port or 5 V USB-C charger available, as the included USB-A to USB-C cable requires a host port or adapter to operate.

Sustained Load Behaviour

The switch forwards traffic at up to 1000 megabytes_per_second with support for 9216-byte jumbo frames. Its fanless design relies on passive cooling through the plastic case, so continuous full-duplex throughput across all five ports will raise the chassis temperature without active airflow. The unmanaged firmware maintains wire-speed switching without software intervention.

Questions about this item

What comes in the box and what must I buy separately?

The box contains the GS105U switch, an installation guide, and a USB-A to USB-C power cable. You will need to supply your own Ethernet cables and a 5 V USB power source such as a wall adapter or powered hub.

Which version should I choose for a desktop with five wired devices?

The GS105U is a single 5-port model with 10/100/1000 Mbps RJ45 ports and a USB-C power jack; there are no other capacity or port-count variants to select from.

What does the 1000 Mbps rating mean when the switch is connected to my router and PC?

Each of the five RJ45 ports negotiates up to 1000 Mbps full duplex, so a PC, console, or printer linked to any port can transfer data at gigabit speed provided the uplink and cabling also support 1000 Mbps.
