Overview
Not a tower and not a gaming rig with a graphics card, the KAMRUI mini PC is a small box built on an AMD Ryzen mobile chip with integrated Radeon graphics. It stands on a desk or hangs on the back of a monitor with the included VESA bracket.
Running three displays from a box smaller than a hardback book is the reason to buy. Gaming relies on integrated graphics, so modern titles need low settings, and memory is soldered at its installed amount.
Who it's for
Spreadsheets, browsing, video calls and media playback across several screens suit this mini PC. Players chasing modern games at high detail need a dedicated graphics card.
Pros and cons
- Drives three monitors at once
- Mounts behind a monitor
- Two storage slots for upgrades
- Fast wired LAN port
- Memory capped at installed amount
- Integrated graphics only
- Operating system not stated in the specs
Performance notes
The Ryzen chip runs at a low default power, which favors quiet operation and efficiency over sustained peak speed. Graphics share system memory, so game frame rates depend on how much memory the GPU can borrow. The built in fan handles cooling under multitasking loads.
