Detailed in an October 16, 2026 hardware review and side-profile inspection by Ryan Smith and Patrick Kennedy at ServeTheHome, the right-side port cluster of the Surface Laptop Ultra—labeled "Side 2" in the publication's hardware tour—illustrates how Microsoft is rethinking workstation connectivity as it targets Apple's MacBook Pro audience. Rather than choosing between a dedicated magnetic charging connector and a high-speed data port, Microsoft fused the two concepts together while surrounding the connector with legacy-friendly and creator-focused I/O.
Inside the Right-Side Port Layout ("Side 2")
When evaluating a developer- or creator-grade laptop, port placement matters almost as much as port count. According to ServeTheHome's examination of the Surface Laptop Ultra's right edge, Microsoft populated this side of the aluminum chassis with three distinct connectors:
- Magnetic Connect Port (40Gbps USB-C): A specialized USB Type-C receptacle flanked by magnets and built with an enlarged outer housing to secure the included magnetic charging cable while maintaining full USB-C data capabilities.
- USB Type-A Port (10Gbps): A standard rectangular USB-A receptacle for legacy peripherals, hardware security keys, flash drives, and debugging equipment without requiring a dongle.
- Full-Size SD Card Reader: A media slot aimed at photographers, videographers, and field engineers moving data off removable flash cards.
While both Microsoft's May 31, 2026 Surface Devices Blog announcement by Corporate Vice President Brett Ostrum and ServeTheHome's review confirm the presence of the full-size SD card slot, neither Microsoft's published specifications nor ServeTheHome's initial hardware breakdown specify the exact SD card generation, UHS bus speed, or maximum transfer rate supported by the reader. Even so, keeping a full-size SD slot alongside a 10Gbps USB-A port on the right flank ensures that quick-access media and thumb drives stay accessible without crowding display cables on the left edge.
Complete Surface Laptop Ultra I/O Breakdown
To understand how the right-side ports fit into a daily desk setup, it helps to look at the entire machine. ServeTheHome's review documents the full left- and right-side connectivity of the 15-inch chassis:
| Chassis Side | Port / Connector | Reported Capability & Notes |
|---|---|---|
| Right Side (Side 2) | 1x USB-C (Magnetic Connect) | 40Gbps data and charging; flanked by magnets with an enlarged outer port body |
| Right Side (Side 2) | 1x USB-A | 10Gbps data transfer |
| Right Side (Side 2) | 1x SD Card Reader | Full-size SD slot (specific card standard/speed unspecified) |
| Left Side (Side 1) | 2x USB-C | 40Gbps data, DisplayPort Alternate Mode, up to 140W charging (non-Thunderbolt 4 certified) |
| Left Side (Side 1) | 1x HDMI | Dedicated HDMI 2.1b display output |
| Left Side (Side 1) | 1x Audio Jack | 3.5mm combo headphone/microphone jack |
Section Summary: The Surface Laptop Ultra splits its connectivity across both edges, placing fixed display and standard USB-C expansion on the left while reserving the right side for removable media, a 10Gbps USB-A accessory port, and the new 40Gbps Magnetic Connect port.
How Microsoft's Magnetic Connect Actually Works
If you have ever inspected the delicate 24-pin tongue inside a standard USB Type-C receptacle, you know why yanking a laptop cord at an awkward angle makes hardware technicians wince. Standard USB-C relies on friction fit; if a cable gets snagged, that mechanical leverage transfers straight into the port wall and the motherboard solder joints.
As ServeTheHome explains in its analysis of the right-side ports, Microsoft's Magnetic Connect replaces the retired Surface Connect port with a design that directly counters Apple's MagSafe—with one major functional twist. On modern MacBooks, MagSafe 3 is strictly a power delivery interface. Microsoft's Magnetic Connect, by contrast, is a standard 24-pin, 40Gbps USB-C connector at its core, meaning it handles both power delivery and high-speed USB-C data.
How did Microsoft make a standard USB-C interface magnetic and trip-resistant? According to ServeTheHome's inspection, the engineering comes down to two physical modifications:
- Flanking Magnets: The USB-C pin assembly itself is not magnetic; instead, Microsoft embedded magnets on either side of the receptacle to pull and hold the matching Magnetic Connect USB-C charging cable firmly against the chassis.
- Enlarged Outer Housing: Looking closely at the right side of the laptop, the outer cavity of the Magnetic Connect port is noticeably wider and taller than a conventional USB-C cutout. ServeTheHome notes that Microsoft enlarged this outer body so the specialized plug can pivot and break away cleanly under lateral strain without snapping the delicate 24-pin USB-C connector inside.
Because the underlying electrical interface is still standard USB-C, power delivery is not locked to one side of the machine. ServeTheHome points out that the Surface Laptop Ultra can charge through any of its three USB-C ports at up to 140W. However, there is an important cable caveat for IT buyers and road warriors: while the right-side Magnetic Connect port accepts the bundled magnetic cable, the two standard-sized 40Gbps USB-C ports on the left side require a regular USB-C cable.
The 40Gbps Controller Question and Missing Thunderbolt Badge
There is another intriguing technical detail beneath the surface of these ports. While all three USB-C ports on the Surface Laptop Ultra are rated for 40Gbps speeds and support DisplayPort Alternate Mode along with 140W power delivery, ServeTheHome observes that Microsoft did not secure Thunderbolt 4 certification for the laptop. Furthermore, because the laptop is powered by NVIDIA's Arm-based RTX Spark N1X system-on-chip—which, according to ServeTheHome, does not natively provide 40Gbps USB lanes on the SoC itself—reviewers noted they were still investigating which third-party controller Microsoft used on the motherboard to drive the 40Gbps ports.
Section Summary: Magnetic Connect is not a proprietary pinout; it is a 40Gbps USB-C port housed in a wider mechanical shell with magnets on either side to allow safer breakaway charging while preserving full USB-C data functionality.
Why This Port Strategy Matters for the Surface Laptop Ultra
To appreciate why Microsoft invested mechanical engineering effort into a reinforced magnetic USB-C port, consider the broader machine wrapped around it. Announced on May 31, 2026, and reviewed in October 2026, the Surface Laptop Ultra is Microsoft's flagship Windows 11 Pro workstation built in partnership with NVIDIA. Measuring 19.16 mm (0.75 inches) thick and weighing 2.0 kg (4.41 pounds), the single-size 15-inch aluminum laptop is built for AI developers, creators, and software engineers who run heavy local workloads.
In ServeTheHome's tested configuration, the system pairs an 18-core or 20-core NVIDIA RTX Spark N1X processor (the laptop sibling to NVIDIA's GB10 chip) and an integrated Blackwell RTX GPU with up to 128GB of unified LPDDR5X memory, a 1TB PCIe Gen5 M.2 2280 SSD, Wi-Fi 7, Bluetooth 5.4 with Bluetooth LE Audio support, a 92Wh battery, and a 3270×2180 120Hz mini-LED PixelSense touchscreen rated up to 2,000 nits of peak HDR brightness. In its product announcement, Microsoft and NVIDIA state that the unified memory architecture can dynamically allocate up to 128GB of RAM across CPU and GPU tasks, claiming up to 1 petaflop of theoretical FP4 AI compute (using sparsity) to run up to 120-billion-parameter AI models locally.
A machine pulling up to 140W under heavy compilation or local model inference is going to spend plenty of time tethered to a wall outlet. By placing the Magnetic Connect port on the right side and two standard 40Gbps USB-C ports plus HDMI 2.1b on the left, Microsoft gives users practical cable management flexibility:
- Desk Docking vs. Couch Coding: You can leave a dual-cable or single-cable USB-C workstation setup connected on the left side alongside an HDMI 2.1b monitor, while using the right-side Magnetic Connect port for quick magnetic charging in high-traffic environments like labs, classrooms, or coffee shops.
- No Port Tax for Safety: On laptops with charging-only magnetic ports, the power receptacle is dead space whenever the machine is running on battery. Because Magnetic Connect is a 40Gbps USB-C port, users still have three high-speed USB-C ports available when they need to plug in external NVMe drives or capture devices.
- Practical Trade-Offs to Keep in Mind: Neither Microsoft nor ServeTheHome has published quantitative pull-force or durability test metrics for the wider Magnetic Connect housing, so buyers should treat the breakaway shell as a smart preventative design rather than an indestructible shield. Additionally, IT departments deploying Thunderbolt-only accessories that strictly check for Intel Thunderbolt certification should test compatibility beforehand, given that the 40Gbps ports are non-Thunderbolt certified.
For Windows hardware watchers, the right side of the Surface Laptop Ultra is a welcome sign that premium laptop design does not have to mean stripping away practical ports. Keeping a 10Gbps USB-A port and a full-size SD card reader right next to an innovative magnetic 40Gbps USB-C connector shows that Microsoft is listening to developers and power users who actually plug things into their PCs.
