GEEKOM A9 Mega vs MINISFORUM MS-A2

The exact US retail configuration ships with Windows 11 Pro. GEEKOM also describes the system as Linux-ready, but the manufacturer does not specify a supported distribution on the product page.

Robtech found Windows 11 Pro free of detected malware on its configured sample and reported that Ubuntu recognized every network interface. A barebones retail unit includes neither operating system nor storage.

Takashi Yoshinaga says he purchased the A9 Mega for local-AI work and found Gemma 4 26B A4B text generation fast, simple multimodal image recognition practical, and Qwen 3.6 27B usable in the short demonstration. The video does not report a repeatable tokens-per-second measurement.

GEEKOM rates the IceBlast 5.0 dual-fan and vapor-chamber cooling system for a sustained 120 W processor setting. This is a manufacturer capability claim, not an independently retained endurance result.

Robtech found that the 9955HX's strongest benchmark gains appeared after enabling Performance mode in BIOS, but also observed thermal throttling under load and said the multi-core uplift over its 7945HX comparison was modest.

Robtech reported that Performance mode did not shorten its brief H.264 encode and only shaved seconds from the longer AV1 test. The reviewer also noted that the Radeon 610M lacks AV1 hardware encoding.

The Ryzen AI Max+ 395 includes Radeon 8060S integrated graphics with 40 RDNA 3.5 compute units and shared access to the system's 128GB unified memory.

TechGround handled the A9 Mega at GEEKOM's IFA 2025 booth and showed the exact 128GB Strix Halo prototype, but did not run a reproducible game benchmark. No FPS claim from that demonstration is treated as a measured result.

ServeTheHome emphasized that the Radeon 610M is intended for display output and media acceleration rather than high-end gaming. Robtech likewise found its 3D and GPU-AI results far below systems with discrete mobile GPUs.

The internal slot provides PCIe 4.0 x8 bandwidth in a physical x16 connector. Robtech says a GPU must be single-slot, shorter than 170 mm, and require no auxiliary power; active blower cooling is preferable in the confined bay.

GEEKOM's IceBlast 5.0 system uses two fans and a full-coverage vapor chamber. The public product page claims this supports 120 W sustained operation, but the retained exact-model YouTube sources do not provide controlled temperature or sound-level measurements.

The retained owner video focuses on local AI, while the IFA hands-on used a show-floor prototype. Neither establishes retail-unit idle or load acoustics, so no decibel value is published here.

GEEKOM lists a configurable processor TDP range of 45 to 120 W and describes up to 140 W of heat dissipation for the platform.

Manufacturer power specification · Ryzen AI Max+ 395 configuration

The exact retail system includes a 330 W external power supply. Adapter capacity is not a measurement of normal wall draw, and no independent wall-power result is published from the retained videos.

Manufacturer bundle specification · GMA9MEGAAIMAX+395-1282-US

The chassis contains two PCIe 4.0 x4 M.2 2280 slots, supports up to 4TB in each slot, and exposes RAID 0 and RAID 1. The installed 2TB system drive occupies one slot.

Manufacturer expansion specification · Exact 128GB/2TB retail configuration

GEEKOM provides two 40Gbps USB4 ports with DisplayPort 2.1, two HDMI 2.1 outputs, two 2.5GbE Ethernet ports, Wi-Fi 7, Bluetooth 5.4, and an SDXC card reader.

Manufacturer connectivity specification · A9 Mega chassis

Three PCIe 4.0 x4 storage positions include two M.2 2280/22110 slots and one position that accepts M.2 2280 or a 7 mm U.2 drive through the included adapter. The two conventional M.2 slots default to PCIe 3.0 x4 and must be changed in BIOS for Gen 4.

MINISFORUM officially supports 96GB across two DDR5-5600 SO-DIMM slots. ServeTheHome also booted and exercised 128GB using two 64GB non-ECC modules, but found that ECC SO-DIMMs operated without ECC protection.

The MS-A2 provides two Intel X710 10GbE SFP+ ports, one Intel I226-V 2.5GbE port, and one Realtek RTL8125 2.5GbE port. Its two rear USB-C ports are 10Gbps USB 3.2 Gen 2 with DisplayPort, not USB4.

Robtech observed thermal throttling around 90 C and called cooling the system's largest weakness. ServeTheHome independently found load noise near 50 dBA, so the compact form factor has measurable thermal and acoustic tradeoffs.

Robtech found the two M.2 2280 slots configured for PCIe 3.0 by default. The BIOS exposes PCIe 4.0, but its warning says higher speed may increase overheating risk.
