TP-Link SG105PP-M2 vs Ubiquiti USW-FLEX-MINI-3: Specification Comparison
Both products are 5-port desktop PoE switches intended for small-site and edge deployments, making them genuine cross-shop candidates for installers choosing between unmanaged multi-gigabit PoE++ density and managed gigabit simplicity. The TP-Link TL-SG105PP-M2 leads with 2.5G per-port speeds and 65 W PoE++ (802.3bt) on four ports, while the Ubiquiti USW-FLEX-MINI-3 delivers managed UniFi integration with PoE+ across all five gigabit ports. The comparison centers on port speed and PoE standard, management capability, and physical/power footprint.

Which switch delivers more PoE power and higher per-port bandwidth?
The TL-SG105PP-M2 provides four 2.5 Gbps PoE++ (802.3bt) ports and one 2.5 Gbps non-PoE uplink port, with a stated PoE budget of 65 W and a total power consumption of 123 W. The 802.3bt standard supports up to 90 W per port, making it compatible with high-draw devices such as pan-tilt-zoom cameras, Wi-Fi 6/6E access points, and powered workstations. The switching capacity is listed at 19 Gbps with a forwarding rate of 29.8 Mpps at the 2.5G tier.
The USW-FLEX-MINI-3 provides five 10/100/1000 Mbps gigabit ports with PoE+ (802.3at, up to 30 W per port) across all five ports. Its switching capacity is 10 Gbps and its forwarding rate is 7.44 Mpps. No per-port PoE budget or total PoE wattage is specified in the provided data; only the power supply rating of 5 V, 1 A is listed, which implies a very constrained total power envelope. The TP-Link unit therefore offers substantially higher per-port bandwidth (2.5 Gbps vs. 1 Gbps) and a higher PoE standard (802.3bt vs. 802.3at), though the Ubiquiti covers all five ports with PoE+ versus four on the TP-Link.
Which switch offers the richer management and platform integration story?
The TL-SG105PP-M2 is unmanaged. Its only intelligent behaviors noted in the specs are auto-negotiation and PoE Auto Recovery, which automatically cycles power to a port when a connected device stops responding. There is no VLAN, QoS, IGMP snooping, port mirroring, or remote management capability listed. Configuration is zero-touch by design, which minimizes setup time but eliminates network segmentation and visibility.
The USW-FLEX-MINI-3 is fully managed via UniFi Network and a web GUI. The provided specs cite VLAN, QoS, port mirroring, and IGMP snooping as supported features. For sites already running Ubiquiti's UniFi controller—whether cloud-hosted or on a local console—the FLEX-MINI-3 integrates directly into that management plane, enabling per-port traffic policies, topology visibility, and centralized firmware updates. Buyers without an existing UniFi deployment must factor in the controller dependency as an additional setup requirement.
How do the two switches compare in size, mounting, operating environment, and power requirements?
The TL-SG105PP-M2 measures 294 × 180 × 44 mm (11.6 × 7.1 × 1.7 in) and supports wall or rack mounting. It requires a 100–240 VAC, 50/60 Hz DC power adapter and draws up to 123 W at full PoE load. Its operating temperature range is 0–50 °C (32–122 °F).
The USW-FLEX-MINI-3 is substantially more compact. The spec sheet lists dimensions of 107.16 × 70.15 × 21.17 mm (noting that the provided raw value of 107.16" × 70.15" × 21.17" appears to be a unit-labeling error in the source data and likely refers to millimeters based on physical plausibility and the stated weight of 0.330 lb) and weighs 0.330 lb. It mounts as a desktop or wall unit and is powered by a 5 V, 1 A adapter. Its operating temperature range is −5 to 45 °C (23 to 113 °F), giving it a slight low-end cold-weather advantage over the TP-Link's 0 °C floor. Certifications CE, FCC, and IC are listed for the Ubiquiti; no equivalent certifications are listed in the TP-Link spec data provided.
Which should you choose: the SG105PP-M2 or the USW-FLEX-MINI-3?
Our take: The TL-SG105PP-M2 is the stronger choice when PoE power delivery and port bandwidth are the primary constraints—its four 2.5 Gbps PoE++ (802.3bt) ports and 65 W budget can drive high-draw devices such as Wi-Fi 6E APs or PTZ cameras that exceed the 802.3at ceiling. Its 19 Gbps switching capacity and 29.8 Mpps forwarding rate are both roughly double the USW-FLEX-MINI-3's figures. However, it is entirely unmanaged: no VLAN, no QoS, no remote visibility. The USW-FLEX-MINI-3 is the right pick for sites already invested in the UniFi ecosystem that need centralized management, traffic segmentation, and IGMP snooping at the edge—provided connected devices stay within gigabit and 802.3at power limits. Its smaller form factor and −5 °C cold-start rating also favor space-constrained or mildly harsh installs. Choose the TP-Link for raw multi-gig PoE++ density; choose the Ubiquiti for managed, platform-integrated simplicity.

Frequently Asked Questions
Which should you choose: the SG105PP-M2 or the USW-FLEX-MINI-3?
The TL-SG105PP-M2 is the stronger choice when PoE power delivery and port bandwidth are the primary constraints—its four 2.5 Gbps PoE++ (802.3bt) ports and 65 W budget can drive high-draw devices such as Wi-Fi 6E APs or PTZ cameras that exceed the 802.3at ceiling. Its 19 Gbps switching capacity and 29.8 Mpps forwarding rate are both roughly double the USW-FLEX-MINI-3's figures. However, it is entirely unmanaged: no VLAN, no QoS, no remote visibility. The USW-FLEX-MINI-3 is the right pick for sites already invested in the UniFi ecosystem that need centralized management, traffic segmentation, and IGMP snooping at the edge—provided connected devices stay within gigabit and 802.3at power limits. Its smaller form factor and −5 °C cold-start rating also favor space-constrained or mildly harsh installs. Choose the TP-Link for raw multi-gig PoE++ density; choose the Ubiquiti for managed, platform-integrated simplicity.
Can the USW-FLEX-MINI-3 power a Wi-Fi 6E access point or a PTZ camera that requires more than 30 W?
Based on the provided specs, the USW-FLEX-MINI-3 is listed with PoE+ (802.3at), which is capped at 30 W per port. No total PoE budget is specified in the data provided. Devices requiring more than 30 W—such as certain Wi-Fi 6E APs or high-draw PTZ cameras—would need the TL-SG105PP-M2, which supports PoE++ (802.3bt) up to the standard's 90 W per-port ceiling within the switch's 65 W total budget.
Do I need a separate controller or subscription to manage the USW-FLEX-MINI-3?
The provided specs indicate the USW-FLEX-MINI-3 integrates with UniFi Network and a web GUI. The specs do not specify whether a paid subscription or dedicated hardware controller is required; buyers should verify with Ubiquiti's current documentation whether a UniFi Network application (self-hosted or cloud) is a prerequisite. No such management dependency exists for the TL-SG105PP-M2, which is fully unmanaged.
Is the TL-SG105PP-M2 or the USW-FLEX-MINI-3 better suited for a deployment that already uses a single-vendor managed network platform?
If the existing platform is UniFi, the USW-FLEX-MINI-3 is the appropriate choice—its specs explicitly list UniFi Network integration along with VLAN, QoS, port mirroring, and IGMP snooping. The TL-SG105PP-M2 is unmanaged per its spec data and cannot participate in any centralized management plane. If the priority is maximizing PoE++ wattage and 2.5 Gbps throughput rather than platform integration, the TP-Link is the stronger fit regardless of the existing network brand.
