GMKtec K12 Mini Desktop Computer 13 × 13 × 5.4 cm AMD Ryzen 7 H 255 Processor No Memory No Disk No Operating System
This compact desktop computer is designed for users who demand high computing performance in a small form factor and wish to customise the final configuration to their needs. The device is supplied without pre-installed RAM, internal storage, and operating system, allowing full control over the selection of components used.
The heart of the device is the powerful AMD Ryzen 7 H 255 processor, which features eight computing cores and sixteen threads. The maximum operating frequency of the processor reaches up to 4.9 gigahertz, ensuring very responsive system performance even during demanding tasks. The processor operates across a wide range of power consumption and automatically adjusts performance to current load.
Graphics performance is provided by the integrated AMD Radeon 780M graphics processor with twelve compute units. This graphics chip allows for smooth image display in high resolution and supports simultaneous connection of up to four display devices. The maximum supported image resolution can reach up to 8K with the appropriate type of connection.
The computer supports modern DDR5 RAM, which is the latest generation of high-speed memory. Memory can be installed in a dual-channel configuration with a maximum total capacity of up to 128 gigabytes. This makes the device suitable for very demanding work scenarios.
For data storage, there are three internal slots for M.2 format solid-state drives of length 2280. These slots utilise the fourth generation PCI Express interface, which ensures very high transfer speeds. The total maximum supported capacity of internal storage can reach up to 24 terabytes, depending on the drives used.
The device is equipped with two network connectors for wired internet connection, each supporting a transfer speed of up to 2.5 gigabits per second. For wireless connectivity, there is a sixth generation wireless network available, which allows stable connections even in modern networks, and Bluetooth version 5.2 technology for connecting wireless peripherals.
Video outputs include an HDMI version 2.1 connector, a DisplayPort version 1.4 connector, a universal USB-C connector supporting video, data, and power transfer, and a high-speed USB fourth generation connector. This combination allows for the simultaneous connection of multiple monitors and achieving very high image resolution.
On the back of the device, there is an Oculink expansion connector that allows for direct connection of a high-speed external graphics card. This type of connection is intended for fixed installation when the device is powered off and is not designed for hot-plugging.
The computer is equipped with an advanced cooling system featuring a pair of heat pipes and separate fans for the processor and storage. The airflow is designed to evenly dissipate heat from all key components. The fans are complemented by adjustable RGB lighting with several display modes.
Powering the device is managed by an external power adapter with an operating voltage of 19 volts. The computer is designed for operation in standard indoor environments within a temperature range of minus ten to forty-five degrees Celsius at standard humidity levels.
Thanks to its very compact dimensions, the computer can be placed directly on a desk or mounted on the back of a monitor or on a wall using the included bracket. The design of the device is focused on long-term stability and effective heat dissipation.
