ASUS NUC 15 Pro+

Published on May 24, 2026

The ASUS NUC 15 Pro+ is the flagship of ASUS’s 2025 NUC lineup, taking the compact 0.7-liter chassis that defined the NUC line and pairing it with Intel’s Arrow Lake Core Ultra processors (Series 2). Built around the Core Ultra 9 285H at the top end, with Core Ultra 7 255H and Core Ultra 5 225H options below it, this is a machine aimed squarely at users who want serious multi-core performance without a tower on their desk. The “Plus” designation matters here: this is the slim, premium model with PCIe 5.0 storage, WiFi 7, and dual Thunderbolt 4, sitting a tier above the standard ASUS NUC 15 Pro. Whether you are building a home lab, running a development workstation, or shopping for a Windows alternative to the Mac mini, the NUC 15 Pro+ delivers desktop-class throughput in a footprint that disappears behind a monitor. It carries forward the toolless design philosophy that made the ASUS NUC 14 Pro so easy to live with.

Detailed Insights into the ASUS NUC 15 Pro+

The NUC 15 Pro+ measures 5.67 by 4.41 by 1.65 inches and weighs roughly 1.3 pounds, keeping the slim, low-profile silhouette that distinguishes the Plus model from the taller standard NUC 15 Pro. The chassis is a toolless silver aluminum design: a latch releases the bottom panel so you can reach the two DDR5 SO-DIMM slots and dual M.2 slots without a screwdriver, and several owners single out the blue NVMe locking ring as a genuinely clever touch that makes drive installs take under a minute. The front panel carries a 20Gbps USB-C port (USB 3.2 Gen2x2) flanked by two 10Gbps USB-A ports and the power button, while the rear hosts the dual Thunderbolt 4 ports, an additional USB-A, a USB 2.0 port, two HDMI outputs, and the 2.5-gigabit Ethernet jack. One notable omission is the lack of a 3.5mm audio jack, so headphone and speaker connections rely on USB, HDMI, or Bluetooth.

At the heart of the flagship configuration is the Intel Core Ultra 9 285H, a 16-core, 22-thread Arrow Lake processor that boosts to 5.1GHz and scores roughly 34,500 on the PassMark CPU benchmark. That puts it well ahead of the previous-generation NUC 14 Pro and into territory where 4K video timeline scrubbing, heavy multitasking, and software development with dozens of browser tabs feel effortless. The integrated Intel Arc 140T graphics handle media playback, hardware-accelerated encoding, and light creative work, and the processor’s NPU enables on-device AI features, though as with most integrated solutions this is not a gaming GPU. Owners running Ubuntu for programming and home automation describe it as a versatile, performant box, with one noting it comfortably drove a large RAM disk after installing 96GB of memory.

Connectivity is current across the board. The machine ships with WiFi 7 (802.11be) and Bluetooth 5.4, while the wired side uses Intel’s I226-V controller for 2.5-gigabit Ethernet. The dual Thunderbolt 4 ports support DisplayPort 2.1 alt mode, and combined with the two HDMI outputs the NUC 15 Pro+ can drive up to four displays, with owners reporting 8K at 60Hz over Thunderbolt. Storage expansion is generous for the size: the primary M.2 2280 slot runs at PCIe 5.0 x4 for the fastest current drives, and a second M.2 2242 slot at PCIe 4.0 x4 adds capacity. Memory tops out at 96GB across the two SO-DIMM slots, enough headroom for virtualization or large in-memory workloads.

Reviewer Insights on the ASUS NUC 15 Pro+

Video coverage of the NUC 15 Pro+ has been enthusiastic about its raw speed. Robtech framed the launch around performance, billing it as the fastest Intel mini PC available at the time of release and walking through the chassis, upgrade process, and thermals. The Geeky Ricky reaches a similar conclusion, describing the system as a compact powerhouse, while Gearvlog with Mike puts the Arrow Lake silicon through a dedicated benchmark run. The embedded video reviews above are the best place to see the hardware in motion and hear each reviewer’s hands-on impressions.

Across this video coverage the consensus is consistent: the NUC 15 Pro+ is a standout performer for its size, and the main reservations are about price positioning and the usual integrated-graphics gaming ceiling rather than the core hardware.

Customer Reviews of the ASUS NUC 15 Pro+

Amazon customers have rated the NUC 15 Pro+ around 4.2 out of 5 stars across more than 40 reviews on the flagship listing. The most consistent praise is for how quiet it runs: multiple buyers describe the fans turning off entirely during light tasks, and one reviewer called it the best ultra-small-form-factor unit on the market after installing 64GB of DDR5 and a Gen5 NVMe drive and finding it stayed cool under load. The toolless servicing comes up repeatedly as a highlight, as does the expansion headroom, with owners confirming support for large memory configurations and 8K output over Thunderbolt 4.

The criticism is just as specific. The most pointed negative review documents firmware and hardware frustrations, including the system failing to sleep or wake reliably, intermittent USB connectivity drops, and audio interference attributed to grounding, with that owner concluding the support experience did not match the hardware’s price. A separate reviewer who was otherwise very pleased flagged that the Bluetooth radio became unreliable beyond about five feet, pushing them toward 2.4GHz peripherals instead. These reports are worth weighing against the many positive ones, since they point to platform and firmware maturity rather than a fundamental design flaw.

On balance, customer sentiment is positive, with the NUC 15 Pro+ landing as a fast, well-built, easily serviced machine whose rough edges are mostly in firmware polish. Buyers who value a quiet, compact, upgradeable workstation tend to be very happy with it, while those who lean heavily on Bluetooth peripherals or expect flawless sleep behavior out of the box should go in with realistic expectations.

Conclusion

The ASUS NUC 15 Pro+ is the most capable mini PC ASUS has shipped under the NUC banner so far, and it earns the “Plus” name through genuine hardware advantages: the Core Ultra 9 285H, a PCIe 5.0 storage slot, WiFi 7, and dual Thunderbolt 4 in a chassis small enough to hide behind a monitor. For professionals who need a quiet desktop replacement, developers running local workloads, or home lab builders who want plenty of memory and fast storage in a tiny package, it is an easy machine to recommend. The toolless design and broad CPU range, from the Core Ultra 5 225H up to the Core Ultra 9 285H, mean you can match the configuration to your budget and workload.

That said, this is a premium product and it expects you to treat it like one. If you rely on a wired headset jack, want dual high-speed Ethernet, or plan to game on integrated graphics, look elsewhere or budget for a Thunderbolt eGPU. The firmware quirks a minority of owners report are worth researching against your intended operating system before buying. Shoppers cross-shopping the Mac mini for a Windows or Linux workstation should also weigh the Mac mini M4 on price and platform fit.
