Minis Forum X1-255 AMD Ryzen 7 H255 miniPC, barebone
Minis Forum X1-255 is a high-performance PC that is suitable for both office work and more demanding tasks. Equipped with a powerful AMD Ryzen™ 7 processor and a variety of connectors, it allows you to freely customize your configuration. Thanks to its compact dimensions (128 x 126.5 x 52.5 mm), it will fit virtually anywhere - on a desk, behind a monitor or in a workspace with limited space.
Powerful AMD Zen 4-series processor
At the heart of the device is an 8-core and 16-thread AMD Ryzen™ 7 255 processor, based on the Zen 4 architecture. A base clock speed of 3.8 GHz with the ability to accelerate to 4.9 GHz ensures smooth operation in office applications, browsers, and even lighter 3D modeling or video editing.
Built-in AMD Radeon™ 780M graphics
The integrated AMD Radeon™ 780M graphics chip allows for smooth high-definition multimedia and even simple graphics processing. It's a reasonable choice for users who don't need a dedicated graphics card, but still expect smooth image handling.
Flexible memory and disk configuration
The X1-255 supports up to 64 GB of DDR5 memory clocked at 5600 MT/s for fast application loading and seamless multitasking. Two M.2 NVMe SSD (PCIe 4.0) slots support the installation of drives up to 4TB each, allowing you to build ultra-fast and high-capacity storage without external solutions.
Efficient cooling and quiet operation
A turbo fan with a speed of up to 4,000 rpm and a variable-phase material is responsible for cooling. This system effectively maintains a low temperature even under full load, while remaining quiet - in Silent mode it generates just 38 dB.
Reliable connectivity
The MiniPC offers a wide selection of ports, including USB4, HDMI 2.1 FRL, DisplayPort, OCuLink, as well as a 2.5G LAN connector. This makes it easy to connect a 4K/8K monitor, high-speed external drive or other accessories. The computer also supports Wi-Fi 7 and Bluetooth 5.4 for stable wireless connectivity.
With convenience and installation in mind
The unit comes with a standard VESA mounting hole for easy installation on the back of a monitor, for example. You'll also find a power button, a Kensington Lock slot for theft protection and a dedicated reset hole.
