Mini PC GMKtec K12 Ryzen 7 H 225 32GB RAM + 1TB SSD WIN 11 Pro

MINI PC GMKtec K12 Ryzen 7 H255 32GB RAM + 1TB SSD WIN 11 Pro

The GMKtec K12 Mini PC is powered by a custom AMD Ryzen 7 H255 processor, which surpasses the performance of the Ryzen 7 8745HS model. The octa-core and sixteen-threaded unit, clocked at up to 4.9 GHz and with a 16 MB cache, easily handles multitasking and compute-intensive workloads. With a TDP range of 35–54 W, it achieves the perfect balance between performance and energy efficiency. The device comes with Windows 11 Pro installed. It is also compatible with Linux.

Impressive performance with Ryzen 7 H255
High computing power is provided by the AMD Ryzen 7 H255 processor, whose performance surpasses the Ryzen 7 8745HS, 7840HS, and 6800H models. Eight cores and sixteen threads, clocked at up to 4.9 GHz and 16 MB of cache memory guarantee smooth operation of demanding applications and multitasking without performance drops. The chip is made using TSMC's 4 nm lithography, and with a TDP of 54 W, the PC offers stable operation even under heavy load.

Integrated graphics with the power of an independent card
The powerful AMD Radeon 780M chip provides smooth operation of games and graphics programs, offering performance comparable to dedicated GPU cards. The GPU clock frequency is 2600 MHz, and the RDNA 3 architecture used guarantees high frame rates – in popular titles up to 182 FPS in e-sports games and 127 FPS in productions with more advanced graphics. The integrated chip also copes admirably with video editing, 3D design, and high-definition multimedia, making the K12 a versatile computer for work and entertainment.

8K image on four screens
The device supports up to four simultaneous monitors at resolutions up to 8K, offering an exceptional visual experience and a large workspace. It features ports such as USB 4.0, USB-C, DisplayPort 1.4, and HDMI 2.1, allowing you to connect a variety of devices – from monitors and graphics tablets to TVs and projectors. It's ideal for creatives, analysts, and professionals who need a powerful mini PC for multi-screen work and top-quality image processing.

Everything you need for work and entertainment
Create a fully functional workstation for work, gaming, and multimedia. At your disposal are 2 USB-C ports, 5 USB-A ports, HDMI 2.1, DisplayPort, 2×2.5G LAN ports, a CTIA 3.5 mm audio jack, and an OCuLink (PCIe Gen4 x4) port for connecting an external graphics card. Such equipment ensures full compatibility with modern devices and guarantees comfortable use in the office, home, or studio.

Support for external graphics cards
The OCuLink port allows you to connect an external graphics card, significantly increasing the computer's capabilities in gaming, rendering, and graphics work. Such a solution allows you to achieve performance comparable to full-size PCs while maintaining the compact size of the device. Note that the OCuLink port does not support hot-plug functionality, so connecting or disconnecting the card should be done with the computer turned off.

Stable connection in any situation
GMKtec K12 is equipped with two 2.5G Ethernet ports, which provide fast and stable data transfer – up to 2500 MB/s. This ensures reliability in bandwidth-intensive applications – from office work, transferring large files, to media servers or monitoring systems. The computer maintains a constant transmission speed and high responsiveness. Using Wi-Fi 6E and Bluetooth 5.2 technology, the GMKtec K12 offers fast and stable connections in all conditions.

Easy memory and disk expansion
The design of the GMKtec K12 has been developed for simplicity of upgrades and maximum flexibility. With easy access to components, you can expand your computer's capabilities by mounting up to three M.2 2280 PCIe 4.0 SSDs, each up to 8 TB (total max 24 TB). In addition, two DDR5 5600 MHz SO-DIMM slots support up to 128 GB of RAM (max 64 GB per slot), allowing you to customize your configuration for the most demanding applications.

Advanced cooling
The heat dissipation system combines two fans with a copper base to ensure stable operation for up to 72 hours at 70 W TDP load. The convection airflow design increases cooling efficiency by up to 200% compared to classic Tower PCs while maintaining a compact chassis. Intelligent system fans and thoughtful airflow distribution maintain optimal component temperatures, while RGB backlighting adds a modern, striking touch. The GMKtec K12 allows seamless switching between three operating modes – Quiet (35–40 W), Balanced (54–60 W), and Performance (65–70 W).
