Mini PC GMKtec K15 with Intel Core Ultra 5 125U, 16GB RAM, 1TB SSD, Windows 11 Pro

GMKtec K15 mini PC with Intel Core Ultra 5 125U, 16GB RAM and 1TB SSD is a compact desktop solution designed for everyday computing, office workflows, multimedia playback and light productivity tasks. The system runs Windows 11 Pro and integrates DDR5 memory and a PCIe 4.0 SSD to provide responsive performance in a small form factor. Connectivity options include dual 2.5 Gb/s Ethernet, Wi‑Fi 6E and multiple display outputs, while an intelligent cooling system and configurable power modes allow balancing noise, temperature and processing power.

Advantages

The K15 combines a hybrid Intel Core Ultra 5 125U processor with integrated Intel Xe graphics and a dedicated NPU for on‑device AI acceleration, enabling faster AI inference and smoother multimedia processing without overloading the CPU. Fast PCIe 4.0 storage and DDR5 memory improve application responsiveness and multitasking. A rich set of I/O, including USB4.0, HDMI 2.1, DisplayPort 1.4 and an OCuLink PCIe 4.0 x4 connector, expands connectivity and allows external expansion. The compact chassis includes an effective dual‑fan cooling system and adjustable RGB backlighting while Windows 11 Pro comes preinstalled for immediate use.

Suitable for

• Office productivity and remote work environments

How to use

Connect the included power supply and video cable, attach peripherals (keyboard, mouse, network) and power on the mini PC. Use Windows 11 Pro setup to configure user accounts, network settings and system updates. Select an operating mode (Silent, Balance, Performance) in the system control utility to match noise and performance requirements. For multi‑monitor setups, connect displays to HDMI 2.1, DisplayPort 1.4 or USB4.0/USB‑C outputs and arrange screens in Windows display settings. Install additional M.2 SSDs or RAM only after powering off and following anti‑static precautions.

Usage recommendations

For consistent thermal performance and reduced noise, place the mini PC with unobstructed airflow around top and side vents and avoid enclosed spaces. Use Balance mode for general office tasks and switch to Performance mode for heavier workloads. When connecting expansion devices via OCuLink, power down the system before installation, as hot‑plug is not supported.
