KAMRUI is an integrated high-tech enterprise committed to the research and development, production and sales of smart products such as Mini PCs and PC sticks. Every KAMRUI Mini PC blends a stylish design with high-performance professional features, creating an incredible end-user experience for office and home use, gaming, business and home entertainment alike.

Since its inception, KAMRUI has focused relentlessly on technology research and development in order to provide professional Mini PCs and portable PC sticks to customers worldwide at affordable prices.

The AM21 is the clearest expression of that mission yet. At its heart sits the AMD Ryzen 7 8745HS, an 8-core, 16-thread Zen 4 processor boosting up to 4.9GHz. Performance enthusiasts will appreciate the numbers: its multi-core performance outperforms the Intel Ultra 7 155H by 18 percent, the Ryzen 7 PRO 6850H by 24 percent and the Ryzen 7 7735HS by 27 percent. That translates directly into real-world speed — instant application launches, fluid multitasking, rapid renders, responsive virtual machines and consistently smooth frame delivery in games. It is an ideal foundation for gaming, content creation and heavy multitasking, and it delivers all of that in a system that stays cool, quiet and composed.

Mini PC for office

The AM21 is built to be your daily workhorse. 16GB of DDR5 memory keeps dozens of browser tabs, spreadsheets, messaging apps and background services running without hesitation, while a 512GB high-speed PCIe 4.0 NVMe SSD delivers snappy boot times and near-instant file access. When your ambitions grow, so does the AM21: memory expands up to 96GB and dual M.2 slots let you expand storage up to 4TB, perfectly suited for virtual machines, large media collections and ultra-fast system booting.

Connectivity is where this mini PC truly shines. The versatile full-featured port array includes 1 × DC port, 2 × USB 3.2 Gen2 Type-A (10Gbps), 1 × USB4 Type-C (40Gbps data, DP1.4 8K@60Hz / 4K@120Hz, 100W PD input), 1 × full-function USB 3.2 Gen2 Type-C (10Gbps data, DP1.4 4K@60Hz, 100W PD input), 2 × 1Gbps RJ45 Ethernet ports, 2 × HDMI 2.1 (4K@60Hz) and 1 × audio in/out jack. Multiple screen display support lets you drive several monitors at once for expansive spreadsheets, editing timelines and live dashboards. Dual Gigabit Ethernet makes the AM21 a natural fit for office workstations, servers and surveillance applications, while 100W PD input allows you to power the system over USB-C for a cleaner, simpler desk setup. Monitors, projectors and other multimedia and commercial equipment connect seamlessly, making this an exceptionally flexible hub for productivity.

Keeping all of that running at full tilt is the KAMRUI all-copper cooling system. The assembly combines heat pipes, copper fins and a high-speed silent fan, with three D8 heat pipes and dual air intakes working together to achieve effective heat dissipation and maintain steady performance during prolonged heavy loads. The system runs cool with a maximum noise level of only 41.0dB under full load, making it ideal for 24/7 office server and studio operation.
