NucBox K15 mini PC offers Intel Ultra CPU and GPU expansion docks at the lowest price ever seen
- NucBox K15 supports up to 24TB SSD with three M.2 slots
- Intel Core Ultra 5 processor efficiently provides twelve cores and fourteen threads
- Integrated GPU handles basic graphics workloads, but not extreme gaming demands
In recent years, more powerful mini-PCs with desktop-like performance have come onto the market, although their price often remains a disadvantage.
The GMKtec NucBox K15 mini PC, with OCuLink support, appears to challenge this model with a starting price of $360.
This device uses the Intel Core Ultra 5 125U processor, which offers twelve cores and fourteen threads.
Hybrid CPU architecture and AI acceleration
It uses a hybrid design with 2 performance cores, 8 efficiency cores and 2 low-power efficiency cores, with a maximum turbo frequency of up to 4.3 GHz and 12 MB Intel Smart Cache.
The integrated Intel Graphics GPU reaches a maximum dynamic frequency of 1.85 GHz and supports up to 7TOPS for AI workloads.
With the Intel AI Boost NPU, the system delivers up to 21TOPS of AI performance and supports ray tracing and multi-format hardware encoding and decoding.
Memory options include 16GB or 32GB DDR5 RAM, expandable to 96GB, while storage comes pre-installed with 1TB or 2TB M.2 PCIe 3.0 SSD.
The system also offers three internal M.2 PCIe 4.0 × 4 slots, allowing up to 24 TB of total storage.
The NucBox K15 Mini PC supports four simultaneous quad display outputs via HDMI 2.1, DP 1.4, USB4 and Type-C ports.
It also supports WiFi 6E and Bluetooth 5.2, as well as two 2.5G LAN ports for wired connections.
Front and rear I/O include multiple USB-A and USB-C ports, an OCuLink PCIe Gen4x4 slot, an audio jack, and a DC input.
The rear-mounted OCuLink interface allows connection to external GPU expansion stations supporting NVIDIA RTX 40 and 50 series graphics cards.
This setup effectively turns the mini PC into a high-performance gaming and graphics workstation.
The mini PC comes with Windows 11 Pro preinstalled and also supports Linux distributions such as Ubuntu.
A dual-fan cooling system with copper heat pipes helps maintain thermal performance under heavy load.
The CPU fan and system fan work together to reduce noise while maintaining efficiency.
The fans use intelligent control and the design includes dust protection to extend component life.
The NucBox K15 is available on GMKTec’s website, with the barebones model starting at $360, while the variant with 32GB of RAM retails for $480.
Top configurations with 16GB RAM and 1TB SSD cost $579.99, while the 32GB RAM and 1TB SSD version is priced at $699.99.
Comparable mini PCs such as the Asus NUC 14 Pro+ with a similar Intel chip cost over $500 for the barebones model.
Likewise, the barebones version of the Beelink SER9 Pro with a Ryzen 7 H 255 processor costs around $500.
The K15’s lower price makes it attractive, although power users might find its GPU performance limited for demanding graphics workloads.
