Product Details
- RYZEN 7 H 255 CPU - The Ryzen 7 H 255 is a chip from the Hawk Point family and is an upgraded version of the older Ryzen 7 8745H and has 8 cores (16 threads thanks to SMT support) that run at up to 4.9 GHz, together with the powerful Radeon 780M iGPU. Unlike Zen 3, Zen 4 offers AVX512 support along with other improvements such as larger caches/registers/buffers across the board.
- GAMING PC - The Radeon 780M (12 CUs / 768 shaders, up to 2,600 MHz) can drive multiple displays simultaneously with a resolution of up to 8K. Hardware encoding and hardware decoding of the most common video codecs (AV1, AVC, HEVC) is also no problem; playing the latest games on FSR settings without issues.
- 32GB DDR5 RAM + 512GB SSD - The K12 mini computer is equipped with Dual 16GB (Total 32GB) SO-DIMM DDR5 5600MHz memory sticks. 512GB PCIE 4.0 SSD Drive with 3x M.2 2280 Expansion slots. Each slot capable of reading up to 8TB. (24TB MAX)
- QUAD SCREEN 4K DISPLAY SUPPORT - K12 Mini PC support 4-screen 4K/8K output via HDMI 2.1 (8K@60Hz), DisplayPort 1.4 (4K@60Hz), and USB Type-C Transfer speed (supporting PD3.0/DP1.4/DATA). Ideal for gaming, video editing, and multitasking, it provides expansive and crisp multi-display support.
- OCULINK PORT - The Oculink port on the rear interface enables higher bandwidth capabilities, better frame rates and lower lag. The standard also operates at PCIe x4 speeds, compared to Thunderbolt's x3. Gamers and content creators can benefit from Oculink's higher bandwidth, resulting in better performance and lower lag for eGPU setups
- DUAL NIC FAST 2.5GBE + WIFI 6E + BT 5.2 - Dual Ethernet 2.5GbE LAN port design provides more applications, such as firewall, multichannel aggregation, soft routing, file storage server. Built-in WIFI 6E / Bluetooth 5.2 is more stable and efficient to connect multiple wireless devices such as projector, printer, monitor, speakers and etc.
- DUAL COOLING FANS WITH LIGHTING - Turbo CPU fan + a massive DDR5/SSD cooling fan deliver silent, ultra-efficient cooling (just 35dB in Quiet Mode!), while the advanced heatpipes and 360° airflow keeps your Ryzen Mini PC frosty under heavy loads. Plus, 13 dazzling RGB lighting modes let you personalize your rig’s vibe.
