Ready-to-run mini PC for multitasking

The GMKtec M5 Ultra Black arrives with Windows 11 Pro, 32GB of DDR4 memory and a 512GB NVMe drive. An 8-core Ryzen 7 7730U processor reaches 4.5GHz boost clocks, while integrated Radeon graphics drive up to three 4K displays. Dual 2.5GbE ports, WiFi 6E and Bluetooth 5.2 handle wired and wireless networking.

Step up from entry-level boxes

The 35% performance lift over prior M5 models makes the jump worthwhile when you need simultaneous 4K output, virtualisation headroom or a compact PfSense/Unraid node. Builders who want discrete GPU power or more than 64GB of RAM should look elsewhere.

Verify your monitor inputs

Video outputs are HDMI 2.0, DisplayPort and USB-C with DP alt-mode — check that your screens match. The 19V 3.42A adapter is included, so confirm your mains voltage falls within the 100-240V AC range. DDR4 upgrades must be 3200MT/s modules; other DDR generations will not fit.

Questions about this item

What are the physical dimensions and mounting options for the M5 Ultra mini PC?

The unit includes a VESA mount with screws for attachment to the back of a monitor or wall. It uses a 19 V 3.42 A DC power adapter with a 100-240 V AC input.

How do I install additional storage in the dual M.2 2280 slots, and what is the common mistake?

Open the case, insert the PCIe 3.0 x4 NVMe SSD into either M.2 2280 slot at an angle, then secure it with the screw. The common mistake is forgetting to enable the new drive in the BIOS before use.

When will the 32 GB DDR4 3200 MT/s memory need replacement, and what is the upgrade limit?

The installed 32 GB DDR4 dual-channel memory (2 x 16 GB) can be expanded to a maximum of 64 GB. Replacement is only needed if you require more capacity or a module fails.
