Our take on the Kamrui AM21 Mini PC

The Kamrui AM21 is a small desktop built around AMD's Ryzen 7 8745HS, an 8-core laptop-class chip with Radeon 780M integrated graphics. It runs Windows 11 Home from an SSD and outputs over HDMI, so it fits behind a monitor or under a TV. It suits office work, browsing and light gaming, where its integrated graphics beat the Intel UHD graphics in cheap mini PCs but trail dedicated-GPU machines. Buyers should check the RAM and SSD size and the port list, since Kamrui sells several AM21 configurations.

Questions and answers

Is the Kamrui AM21 good for gaming?
It handles older, indie and esports titles at modest settings thanks to the Radeon 780M. Demanding modern games will need lowered settings or won't run smoothly.
How does it compare with an Intel N100 mini PC?
The Ryzen 7 8745HS is much faster for multitasking and light gaming than the N100. The N100 is cheaper and lower power, but far weaker for anything beyond basic office work.
Can I upgrade the RAM and storage?
Most Kamrui mini PCs use replaceable SO-DIMM memory and an M.2 SSD, but check the specific AM21 configuration before buying. Open the case only if you are comfortable doing so.
Does it come with Windows 11?
Yes, it ships with Windows 11 Home preinstalled on the SSD. You set it up on first boot.
How many monitors can it drive?
The listed connectivity is HDMI, so plan on one HDMI display unless the specific unit adds more ports. Check the port list of the exact configuration.
Is it quiet enough for a living room?
At light loads it stays quiet, but the fan can become audible under sustained load. That matters if it sits next to a TV in a quiet room.
Where is the Kamrui AM21 Mini PC cheapest?
At Best Buy, for $339.00, as of our latest check.
Where can I buy the Kamrui AM21 Mini PC?
