Review & Unboxing: MERCUSYS MS105G – The Cheapest 1GbE Switch Available


Searching for a cost-effective and efficient solution to enhance my network connectivity, I stumbled upon the MERCUSYS MS105G, marketed as the cheapest 1Gbit switch available. Naturally, I had to explore it further and provide a detailed review for anyone else on a similar quest.

Specifications and Price

The MERCUSYS MS105G is a compact network switch, packed with 5 Gigabit Ethernet ports. This unmanaged switch offers a combined fabric speed of 10 Gbps, ensuring a stable switching bandwidth. The data rates on offer are impressive, with 10/100/1000 Mbps at Half Duplex and 20/200/2000 Mbps at Full Duplex. A key feature is its support for Jumbo Frame sizes up to 9KB, enhancing data transfer performance over the network.

But the biggest attraction? This powerful piece of tech is available for a mere £7.99, making it a true budget-friendly pick. Moreover, it comes with a 3-year warranty, adding to its value proposition.

Unboxing: What’s Inside?

Inside the simple yet well-packaged box, you’ll find the MERCUSYS MS105G itself. The switch has a sleek design, with a compact, durable build. It’s aesthetically pleasing and would seamlessly fit in any workspace or home.

The front of the switch houses the Ethernet ports, each accompanied by LED indicators. These LEDs are color-coded – green for Gigabit connections and amber for Fast Ethernet connections, which is helpful for quick connection status checks.

Setting Up and Performance

Setting up the MS105G is straightforward. Simply connect your devices to the Ethernet ports using RJ-45 cables, plug in the power supply, and you’re good to go. No software installation or configuration is needed.

One important aspect that caught my eye is the power efficiency. The switch consumes around 5V/0.6A power, but that’s not all. The MERCUSYS MS105G automatically adjusts power consumption based on the link status and cable length, saving up to 82% of power. In an era of energy consciousness, this feature is a definite plus.

Frequently Asked Questions

Backward Compatibility: The MS105G is backward compatible, supporting slower Ethernet speeds (10/100 Mbps) if required.

Managed vs Unmanaged Switches: Managed switches provide more control over your network with features like VLANs and Quality of Service (QoS). Unmanaged switches like the MS105G are plug-and-play, with no additional configuration – perfect for simple, efficient networking needs.

Compatibility and Protocols: The MS105G abides by the IEEE 802.3, IEEE 802.3u, and IEEE 802.3x CSMA/CD protocols, enabling stable and efficient network connectivity. It also has built-in crossover cable detection and collision detection.

Streaming and CCTV: Thanks to its 1Gbit capacity, the MS105G handles 4K movie streaming and 8MP 4K CCTV camera feeds smoothly.


The MERCUSYS MS105G is a budget-friendly, power-efficient, and robust 1GbE switch. It’s easy to set up, offers stable and efficient connectivity, and caters to various needs, from high-quality streaming to surveillance. In my experience, it delivers excellent value for money. If you’re looking for a reliable yet affordable network switch, the MS105G is certainly worth considering.
