GMKtec K1

Updated on January 26, 2026

The GMKtec K1 (also sold as the NucBox K1) is a compact AMD mini PC built on the Ryzen 7 6800H (8 cores, up to 4.7GHz) with integrated Radeon 680M graphics. It takes DDR5 to 64GB and an M.2 NVMe SSD to 2TB, and the top pops off without tools so the RAM and SSD are easy to reach. Connectivity covers Wi-Fi 6, Bluetooth 5.2, 2.5GbE, USB4, and dual HDMI plus USB-C DisplayPort for up to three displays. It runs Windows 11 Pro and suits everyday work, media, and light gaming on the integrated GPU.

A Gen 4 slot filled with a PCIe 3.0 drive

The bundled Lexar NVMe SSD is a PCIe 3.0 part, so a Gen 4 replacement drive is the first upgrade worth making, though you can fit a Gen 4 drive yourself. Memory ships as DDR5-4800 in a single SO-DIMM with room to 64GB, and the Radeon 680M covers light gaming and productivity.

ETA Prime measured a low 16 watts at idle and up to 78 watts under full load, so it is efficient for a 6800H box. Heat gathers near the RAM and M.2 area under sustained load, which Team Pandory noticed. The 4.5 by 4.8 inch footprint, the 1.8 inch height, and the included VESA mount let it sit behind a monitor instead of on the desk.

Reviewer Insights

Team Pandory: limited GPU headroom without super-resolution

Team Pandory reviewed the K1 as a value play and came away positive, running games like Elite Dangerous and Tekken 7 at playable frame rates and noting the unit gets warm around the RAM and M.2. At around $380 he called it “ideal if you’re looking for a decent mini PC and don’t want to break the bank,” with the caveats being limited GPU headroom without super-resolution and the HDMI’s 4K-60Hz cap. On capability, he said: “it can play the latest PC games, and it doesn’t compromise when it comes to emulation.”

ETA Prime: three displays, and a BIOS with no TDP control

Hardware and upgradability were the focus for ETA Prime. He showed the top popping off without tools for easy access to the ADATA DDR5 and the Lexar PCIe 3.0 SSD (with headroom to 64GB and 2TB), and ran three displays off the unit. His main gripe was the locked BIOS, with no way to adjust TDP or RAM speed. On gaming he found reasonable frame rates across settings, and rated it well among GMKtec’s mini PCs for the balance of power and efficiency.

The 680M and the missing Thunderbolt set the ceilings

The 6800H and Radeon 680M cover productivity, media, light gaming, and emulation, and the tool-less access plus the DDR5 and M.2 upgrades make it easy to live with day to day. Two builds shipped, a 16GB/512GB machine at $479.99 and a 32GB/1TB machine at $529.99, and either one takes more memory and a bigger drive later.

Thunderbolt peripherals will not work here, and the bundled SSD is only PCIe 3.0 until you replace it. GMKtec has replaced this model with the GMKtec K12. To line it up against other models, use Starry Hope’s Mini PC Comparison Chart.

Frequently Asked Questions

Can I upgrade the RAM and storage on the GMKtec K1? Yes. The top comes off without tools, and inside sit a DDR5 SO-DIMM slot that takes up to 64GB and an M.2 slot for an NVMe SSD up to 2TB.

What type of processor does the GMKtec K1 use? An AMD Ryzen 7 6800H, with eight cores and 16 threads, a base clock of 3.2 GHz and a boost up to 4.7 GHz.

Does the K1 support multiple displays? Two HDMI ports and DisplayPort over USB-C drive up to three screens at once. The HDMI outputs top out at 4K 60Hz.

What are the connectivity options available on the K1? Wi-Fi 6, Bluetooth 5.2, and 2.5G Ethernet cover the network side. The ports are USB 2.0, USB 3.2, and a USB4 port with eGPU support.

Is the K1 suitable for gaming? The integrated Radeon 680M is not a dedicated graphics card, but it handles light gaming, esports, and emulation well, and Team Pandory found it could play some recent titles with FSR super-resolution enabled. For heavier games you will need to lower the resolution or detail settings.

Does the K1 come with an operating system? Windows 11 Pro comes pre-installed. The drive is reachable without tools, so you can fit your own SSD and put another operating system on it.

Can I use the K1 for professional workloads? The 8-core Ryzen 7 6800H and the support for up to three displays cover office and productivity work. At 4.5 by 4.8 inches it also fits a home-office desk without taking the room a tower would.

Is the K1 fanless? No. It has a cooling fan for the heat the 6800H puts out in a case this small, and it stays quiet in normal use.

What comes included in the box with the K1? The mini PC itself, a power adapter, a VESA mount with screws, an HDMI cable, and a user manual.
