Yxk Mini S15 Ultra

Updated on June 20, 2026

The Yxk Mini S15 Ultra is a thin, fanless mini PC built on the Intel N100 (a quad-core Alder Lake-N chip, up to 3.4GHz) with 16GB of DDR4. The fanless design makes it silent, which suits a home office, a classroom, or a shared desk, and at 6.54 x 5.12 x 1.18 inches it is easy to tuck away. It runs Windows 11 and covers everyday tasks: web browsing, video streaming, office work, and light coding or emulation. It is entry-level hardware, not a machine for demanding workloads.

On connectivity it drives dual 4K displays over HDMI and DisplayPort, has a USB-C port that supports video output, and includes Wi-Fi 6, Bluetooth 5.2, and Gigabit Ethernet. Note that YXK is an obscure brand, so support and long-term availability are uncertain.

Detailed Look at the Yxk Mini S15 Ultra

The Yxk Mini S15 Ultra is powered by the Intel Processor N100, a quad-core CPU with a maximum clock speed of 3.40 GHz. While this processor is not designed for heavy computing tasks, it delivers reliable performance for everyday activities such as web browsing, video streaming, and productivity applications. Paired with 16GB of DDR4 RAM, the Mini S15 Ultra ensures smooth multitasking, making it a practical choice for users who need a responsive system for light to moderate workloads. Its Intel UHD Graphics further support casual gaming, game emulation, and dual 4K display setups, enhancing its versatility for productivity and entertainment.

For connectivity, the USB-C port supports video output (useful with USB-C monitors or AR glasses), and the HDMI and DisplayPort outputs each handle 4K, so you can run a dual-monitor setup. Wi-Fi 6 and Bluetooth 5.2 cover wireless, and a Gigabit Ethernet port handles wired networking.

The fanless design of the Mini S15 Ultra is another highlight, offering silent operation and minimal heat generation. This makes it ideal for quiet environments such as shared workspaces, classrooms, or home offices. The compact form factor (6.54 x 5.12 x 1.18 inches) allows it to fit discreetly on crowded desks or even be tucked away from sight. While it lacks VESA mount compatibility, its lightweight and portable design makes it easy to reposition as needed. With a 512GB M.2 SATA SSD, the Mini S15 Ultra also offers fast storage and quick boot times, with the option to upgrade to a 1TB SSD for users who need additional capacity.

Reviewer Insights on the YXK Mini S15

YXK is a white-label brand, and the S15 Ultra has not drawn the kind of hands-on lab coverage that established mini PCs from Beelink, GEEKOM, or MINISFORUM receive. As of mid-2026 we could not find a single independent reviewer who put this exact unit on a wattmeter or ran their own benchmark suite on it, so the measured numbers a buyer would normally lean on (idle and load wattage, fan-off skin temperatures, sustained all-core clocks) do not exist in the public record for this model. The section below reflects that: it reports what the one trade outlet that covered the machine actually said, and fills the rest with chip facts you can verify yourself.

The most substantial coverage came from CNX Software, where Debashis Das wrote it up on June 27, 2025 as a $119.99 fanless N100 deal rather than a tested review. Das was explicit that the performance figures came from the vendor, not from his own bench: the Cinebench R20 score of 998 points and the 3DMark 11 combined score of 978 are YXK’s own published claims, which CNX relayed without independent verification. Das added the caveat that matters most for a chassis like this, noting that “cooling in such a thin fanless mini PC may not always be optimal, so users should not expect the same level of performance as on actively cooled systems, especially for multi-core workloads.” He placed the device outside demanding work, calling it unsuitable for “video editing or compiling large codebases.”

Treat the vendor’s Cinebench figure as a ceiling, not a promise. The Intel N100 inside is a four-core, four-thread Alder Lake-N part rated at a 6W base power and a 3.4 GHz burst, and it carries a PassMark CPU Mark of roughly 5,643 in our processor database. That was a sensible budget chip when it launched in early 2023; by 2026 it is a known, three-year-old quantity that handles a browser, 1080p and 4K video playback, and office work without complaint and stalls on anything heavier. The fanless design that keeps the S15 Ultra silent is also the reason its sustained multi-core output is likely to sit below an actively cooled N100 once the chassis heat-soaks, exactly the trade-off Das flagged. For durability signals on this specific unit, the owner reports in the Customer Reviews section below are currently more informative than any published review.

Customer Reviews of the Yxk Mini S15 Ultra

Across 64 ratings on Amazon, the Yxk Mini S15 Ultra averages 3.1 stars, and that number hides a sharply split crowd: 37 percent leave five stars while 34 percent leave one. Buyers who are happy tend to praise the value and the basics. GMo, a verified buyer, called it “A nice little unit. Quick & easy to set up,” and James Welhan (also verified) liked the layout, writing that it is “the ONLY N100-Based MiniPC on the market that has ALL THE PORTS AT THE BACK.” Several owners agree it handles web browsing, video, and office work fine for the low price, with the understanding that the N100 chip is not built for gaming.

The one-star reviews point at a consistent problem: reliability over time. Verified buyer Bob Evans reported that it “Worked great for about 3 months,” then the “Wifi started going out intermittently, then Bluetooth died.” Another verified owner, anthony, said it “Did Not Even Last 1 year” before it shut off and would not power back on, and a third buyer reported it bricking after roughly six months. If you are considering this Mini PC, weigh the low cost against the real chance of hardware failure inside the first year that these owners describe.

Conclusion: Who Should Consider the Yxk Mini S15 Ultra?

The Yxk Mini S15 Ultra suits someone who wants a silent, low-cost mini PC for everyday computing: web browsing, video, office work, and light coding or emulation, with dual 4K output and a fanless design that fits a quiet home office or classroom. Windows 11 comes pre-installed, and the small footprint tucks away easily.

The limits are the brand and the chassis. The N100 is fine for daily work but not for gaming or heavy workloads, the RAM caps at 16GB single-channel, and there is no VESA mount. More to the point, the owner reviews flag real reliability complaints (Wi-Fi and Bluetooth failures, units dying inside the first year), and YXK is an obscure brand with uncertain support, so a comparable N100 box from a more established brand (a Beelink, GMKtec, or similar) is the safer buy.
