TL-SG105S-M2 vs TL-SX105: Choose by Link Speed and Setup

Choose by the fastest wired endpoint you actually plan to connect, then check the published body dimensions and adapter output against the installation spot. The TL-SG105S-M2 is the 2.5Gbps ceiling option; the TL-SX105 adds 5Gbps and 10Gbps negotiation. Those are link-rate specifications, not a promise of file-transfer or internet speed.

The buying question

Do your endpoints need links above 2.5Gbps, and which listed switch size and external power profile fits the planned location?

The TL-SG105S-M2 stops at 2.5Gbps per port and has a smaller listed body; the TL-SX105 adds 5Gbps and 10Gbps negotiation options but has a larger listed body and a different external power specification.

Quick verdict

Choose TP-Link TL-SG105S-M2 5-Port 2.5G Multi-Gigabit Desktop Switch if

  • All intended links are 2.5Gbps or slower and the smaller listed TL-SG105S-M2 dimensions suit your surface or wall location.
  • You want its published 9V/0.6A external-adapter output and do not need a 5Gbps or 10Gbps switch port.

Choose TP-Link TL-SX105 5-Port 10G Desktop Switch if

  • At least one planned NAS, NIC, workstation, or access point can negotiate at 5Gbps or 10Gbps, subject to the rest of that link supporting the rate.
  • The larger listed TL-SX105 body and its 12V/2.0A external-adapter output work for your installation.

When to skip: You expect either switch alone to make an internet connection or an endpoint faster; the negotiated link is constrained by the connected devices and the rest of the network path.
When the recommendation changes
  • If all connected endpoints negotiate at 2.5Gbps or below, the TL-SX105's higher port-rate options may not answer a current endpoint need.
  • If a 5Gbps or 10Gbps endpoint is part of the local network, the TL-SG105S-M2's 2.5Gbps port ceiling becomes the limiting switch choice.
  • Check the hardware-version marking and matching TP-Link support page for the exact retail unit before relying on revision-specific specifications; the selected offers' revisions were not established.

The differences that matter

Endpoint Link Speed And Negotiation

TP-Link TL-SG105S-M2 5-Port 2.5G Multi-Gigabit Desktop Switch

Five ports auto-negotiate at 100Mbps, 1Gbps, or 2.5Gbps.[1, 3]

TP-Link TL-SX105 5-Port 10G Desktop Switch

Five ports auto-negotiate at 100Mbps, 1Gbps, 2.5Gbps, 5Gbps, or 10Gbps.[4, 6, 7, 8, 9]

What this changes: Match the negotiated port-rate range to the wired endpoints you actually plan to connect; the switch alone does not make an end-to-end link or internet service reach its headline rate.[1, 4, 6, 7, 8, 9]

The better fit depends on your priorities

Placement And Power Layout

TP-Link TL-SG105S-M2 5-Port 2.5G Multi-Gigabit Desktop Switch

TP-Link lists dimensions of 3.9×3.9×1.0in W×D×H and a 9V DC / 0.6A external-adapter output; it describes the switch as fanless and suitable for desktop or wall mounting.[1, 3]

TP-Link TL-SX105 5-Port 10G Desktop Switch

TP-Link lists dimensions of 8.9×5.2×1.4in W×D×H and a 12V DC / 2.0A external-adapter output; it describes the switch as fanless and suitable for desktop or wall mounting.[4, 6, 7, 8, 9]

What this changes: Compare the listed width, depth, height, and external-adapter output with the actual installation space and power arrangement; do not infer adapter size or physical fit from the output rating.[1, 3, 4, 6, 7, 8, 9]

The better fit depends on your priorities

Best for your routine

A five-port switch for a network whose planned endpoints top out at 2.5Gbps, where the listed body size also fits the installation spot

Best fit: TP-Link TL-SG105S-M2 5-Port 2.5G Multi-Gigabit Desktop Switch

Based on listed features, not comparative testing.

The TL-SG105S-M2 covers the listed 100Mbps/1Gbps/2.5Gbps negotiation range and has smaller manufacturer-listed W×D×H dimensions. It is not suitable for a link that needs the switch port itself to negotiate at 5Gbps or 10Gbps.

A five-port switch for a planned wired endpoint that needs 5Gbps or 10Gbps negotiation

Best fit: TP-Link TL-SX105 5-Port 10G Desktop Switch

Based on listed features, not comparative testing.

The TL-SX105's published port range includes 5Gbps and 10Gbps. The connected endpoint, cable, and other network links must also support the intended rate; this is not a measured-throughput recommendation.

Value and trade-offs

One or both observed offers have eligibility conditions, so no unrestricted price difference is shown.

If current offers show a price premium for the TL-SX105, its 5Gbps and 10Gbps port options are relevant only when the planned wired endpoints and network path can use them.

There is not enough price history to recommend buying now or waiting; compare current offers and terms at purchase time.

Limitations

  • TP-Link's U.S. support pages list multiple hardware revisions for both models and warn that version availability varies by region. The exact hardware revisions associated with the selected retail offers were not established here. The comparison uses the model-level specifications shown on the U.S. product pages and cross-checks TL-SX105's shared port, dimension, mounting, and adapter-output specifications in the reviewed revision datasheets; check the hardware-version marking and matching support page for the unit you receive.
  • Negotiated Ethernet link rates are not observed file-transfer speeds. Results depend on the endpoint ports, cable, traffic and all intervening network links; an internet connection is separately limited by the service and router path.
  • The published adapter output ratings are not power-consumption measurements and do not specify the physical size of either adapter brick. Measure the intended installation before deciding that either unit will fit.
  • No hands-on testing or independent controlled throughput testing was conducted, so no speed, latency, reliability, or noise-performance winner is claimed.

Questions shoppers ask

Will the TL-SX105 make a 1Gbps computer or internet plan run at 10Gbps?

No. The switch lists a port that can negotiate up to 10Gbps, but the computer's network port, cable, other network links, and traffic path also matter. An internet connection additionally depends on the router and service. The switch's rated port ceiling is not a measured transfer rate.

Which dimensions and power number should I check before mounting one?

Use TP-Link's listed W×D×H dimensions and external-adapter output for the model, then confirm the hardware revision on the actual unit and compare its matching support information. The output rating is not the adapter's physical size, so measure the space and check the real cable reach before installing it.

Methodology and sources

Compared the manufacturer-listed port negotiation ranges, W×D×H dimensions, mounting descriptions, and external power-adapter outputs. Cross-checked TL-SX105 shared specifications against its U.S. V1, V2, V3.6, and V4 datasheets. No measured throughput or hands-on installation test was performed.
