Reatan Alloy 9

The Reatan Alloy 9 is a compact AMD mini PC from the small brand Reatan, built around the Ryzen 9 7940HS (8 cores, Radeon 780M graphics) with 32GB of DDR5 and a 1TB NVMe SSD. It runs Windows 11 Pro and is aimed at productivity, creative work, and 1080p gaming on the integrated GPU, with the option to attach an external GPU over its USB4 ports, though Robtech saw an RTX 3070 eGPU bottlenecked, which he put down to limited USB4 bandwidth. Robtech found it one of the quietest high-end mini PCs he had tested in the default balanced mode; performance mode adds fan noise.

A small metal box with two USB4 ports and room to upgrade

At 4.61 x 4.14 x 1.85 inches and about 1.25 pounds, the case is small enough to sit beside a monitor and solid enough that it does not flex. Ports run to dual HDMI (4K at 60Hz), a Realtek 2.5GbE LAN port, four 10Gbps USB-A ports, and two USB4 ports that double as display outputs (up to 8K at 60Hz, per Robtech) and as power inputs. Wireless is Wi-Fi 6E (Team Pandory’s unit had an Intel AX210) and Bluetooth 5.3, though Team Pandory found the signal weak through the metal case; the Realtek 2.5GbE port covers wired networking.

Cooling comes from a larger fan and a heatsink with thermal pads, including a pad over the NVMe drive, and the BIOS exposes balanced and performance modes so you can trade fan speed for sustained clocks. Memory is DDR5 SO-DIMM and goes to 64GB, and there are two PCIe 4.0 M.2 slots for storage. The bundled drive is a slower Gen 3 NVMe, which leaves the faster of the two slots underused until you swap it, so budget for a Gen 4 drive if you care about load times.

Reviewer Insights

Robtech

Robtech titled his review “The BEST Mini PC I’ve Tested” and praised the Apple-like metal design and the 7940HS performance. He rated the CPU and graphics benchmarks highly and ran demanding games at workable frame rates. He found the bottom lid tricky to pry off without the suction cup Reatan supplied; after that, four screws release the heatsink to reach the two DDR5 SO-DIMMs and both M.2 slots. He listed the USB4 ports as rated for 8K at 60Hz and powered the PC from one of them. The BIOS has balanced and performance modes, and he recommended balanced, which made it one of the quietest high-end minis he had tested. His criticisms were the Gen 3 bundled NVMe, no barebones option, and no VESA mount; he also saw an RTX 3070 eGPU over USB4 reach only about 30 FPS at 1080p high with DLSS on, and said the bottleneck was likely the limited USB4 bandwidth.

Team Pandory

Team Pandory saw the CPU sit around 81C under load in the default mode while the system pulled around 95W from the wall. Switching the BIOS to performance mode raised the TDP to 65W and made the fan work harder, for lower temperatures and a bit more noise. In a Cyberpunk 2077 session the system stayed cool with no slowdown. He was impressed by the heatsink, which has thermal pads over the NVMe and direct fan airflow over the memory, and said the tall feet and wedge-shaped case should help keep it cool. He rated it strong for office work, creative tasks, and 1080p gaming, and compared it favorably to the Geekom A7, noting the A7’s metal feels a bit plasticky next to the Alloy 9. His main complaint was wireless signal: Wi-Fi measured only 50% strength through the metal case and Bluetooth controller connections were unreliable, so he used Ethernet and suggests a USB dongle for controllers. He also found the BIOS clunky and wished one of the four rear USB-A ports were on the front.

Verify any listing before you buy one

The Amazon listing that carried the Alloy 9 is currently unavailable, with no date for its return.

Search for the Reatan Alloy 9 (Ryzen 9 7940HS) by name, then read the title, the chip, and the memory on whatever listing comes back and confirm it is a new-condition unit before ordering. Reatan is a small white-label brand, so a listing that matches on brand alone is not enough.

A good box for someone comfortable with an obscure brand

Anyone buying for the silicon gets what they paid for. The 7940HS runs cool in a metal case you can open for more memory or a faster Gen 4 drive, and both reviewers praised the build and the cooling.

Reatan is a small white-label outfit with little support history, and its Amazon listing is currently unavailable. If you can find one in new condition, the machine behind it is good for the money. If you want assured support and a stable buy path, a 7940HS machine from a more established brand such as Beelink, GEEKOM, or Minisforum is the safer call.
