Unleash Next-Gen Gaming and Productivity

At the heart of the K12 lies the AMD Ryzen 7 H 255 CPU, an 8-core, 16-thread beast with a turbo boost up to 4.9 GHz. Built on the advanced Zen 4 architecture, it supports AVX512 instructions, larger caches, and superior multitasking capabilities. Whether you’re gaming, streaming, or rendering high-resolution videos, this processor handles it all effortlessly.

The integrated Radeon 780M GPU (12 CUs, 768 shaders, up to 2,600 MHz) delivers stunning visuals and smooth gameplay, even in modern AAA titles. With AMD FidelityFX Super Resolution (FSR), gamers can enjoy higher frame rates without sacrificing image quality. The GPU also supports AV1, AVC, and HEVC hardware encoding/decoding, making it perfect for video editors and streamers.

Massive Expandable Storage and Blazing-Fast Memory

The K12 comes equipped with 32GB of dual-channel DDR5 RAM (5600MHz), ensuring ultra-responsive performance for memory-intensive applications. Storage is equally impressive, featuring a 512GB PCIe 4.0 SSD and three M.2 2280 expansion slots, each supporting up to 8TB for a potential 24TB total storage capacity. Whether you’re storing vast game libraries or 4K video projects, the K12 has you covered.

Quad 4K/8K Display Support for Immersive Multi-Screen Setups

Experience breathtaking visuals across multiple displays with the K12’s quad-screen output capabilities:

  • HDMI 2.1 (8K@60Hz)
  • DisplayPort 1.4 (4K@60Hz)
  • USB4 (supporting Power Delivery 3.0, DisplayPort 1.4, and high-speed data transfer)

This makes the K12 ideal for multi-monitor gaming, stock trading, video editing, and professional design work, offering crisp, lag-free visuals on every screen.

Oculink Port for eGPU Enthusiasts

The Oculink port sets the K12 apart from competitors, offering PCIe x4 bandwidth for ultra-low-latency connections to external GPUs. Compared to Thunderbolt, Oculink provides higher transfer speeds and reduced input lag, making it the perfect choice for gamers and creators who want to push performance boundaries with an eGPU setup.

Stay connected at lightning speeds with:

  • Dual 2.5GbE LAN ports for network aggregation, firewalls, or NAS setups
  • Wi-Fi 6E for blazing-fast wireless speeds and reduced latency
  • Bluetooth 5.2 for seamless pairing with peripherals like controllers, headsets, and speakers

Advanced Cooling with RGB Lighting

The K12 features a dual-fan cooling system—a turbo CPU fan and a dedicated DDR5/SSD cooling fan—ensuring whisper-quiet operation (just 35dB in Quiet Mode!) even under heavy loads. The 360° airflow design and heat pipes keep temperatures in check, while 13 customizable RGB lighting modes let you personalize your setup for a dazzling gaming aesthetic.
