Minisforum AtomMan G1 Pro

Published on May 24, 2026

The Minisforum AtomMan G1 Pro takes the idea of a small-form-factor desktop and pushes it about as far as a 3.8-liter chassis allows. Inside the white vertical tower sits a 16-core, 32-thread AMD Ryzen 9 8945HX paired with a low-profile desktop NVIDIA GeForce RTX 5060, and the whole thing runs off an internal 350W power supply instead of the usual external brick. That combination of a mobile-class CPU and a genuine desktop graphics card is what separates the G1 Pro from the laptop-GPU mini PCs that dominate this category. Minisforum designed it for people who want to game at 1440p, render video, or run local AI models without surrendering an entire desk to a full tower. The GPU, RAM, storage, and power supply are all serviceable, so the machine is meant to be lived with and upgraded rather than sealed shut.

Detailed Insights into the Minisforum AtomMan G1 Pro

The AtomMan G1 Pro is a vertical tower that measures roughly 12.4 inches tall, 8.5 inches deep, and 2.2 inches wide, with a total volume of about 3.8 liters and a weight near 8.4 pounds. That makes it considerably larger and heavier than a typical palm-sized mini PC, but it is still a fraction of the size of a conventional gaming desktop. The white chassis carries a diagonal ridged texture, an RGB light bar along the front edge, and an included stand with a thumb screw that holds the unit upright. The front panel keeps things clean with a power button, one USB-A 3.2 Gen 2 port, one USB-C data port, and a 3.5mm combo audio jack. Around back, the rear I/O is dominated by the graphics card’s outputs: two HDMI 2.1 ports and three DisplayPort connectors (two DisplayPort 2.1 and one 1.4a), alongside two more USB-A ports, a second USB-C data port, a 5GbE Ethernet jack, and the C14 inlet for the internal power supply.

At the heart of the system is the AMD Ryzen 9 8945HX, a 16-core, 32-thread Zen 4 processor that boosts up to 5.4GHz and scores roughly 51,569 on PassMark’s multi-threaded benchmark. That is a substantial step up from the 8-core HS-class chips found in most mini PCs, and it gives the G1 Pro real headroom for video encoding, compiling, and heavy multitasking. The graphics side is the headline feature: a low-profile desktop RTX 5060 with 8GB of GDDR7, rated at 145W of full power, capable of 614 AI TOPS. Reviewers measured a sustained 245W dual-load output and clocked GPU temperatures around 65 to 70 Celsius during 1440p gaming, while ETA PRIME’s testing noted the CPU can spike into the low 90s Celsius when pushed in Beast mode. A third-generation Glacier cooling system with five copper heat pipes and a 300W thermal rating handles the load, though the fans become clearly audible at the top power profiles.

Connectivity leans modern rather than exhaustive. WiFi 7 and Bluetooth 5.4 cover wireless duties, and a single Realtek RTL8126 5GbE port handles wired networking at speeds well beyond the usual 2.5GbE found at this size. Storage expands through two M.2 slots running PCIe 4.0, accepting both 2230 and 2280 drives and supporting up to 4TB per slot for a total of 8TB. Memory tops out at 96GB of DDR5-5200 across two SODIMM slots. The one notable omission is high-speed USB: there is no USB4 or Thunderbolt here, and both USB-C ports are data only, with all display output handled by the dedicated HDMI and DisplayPort connectors on the graphics card. The system can drive up to four displays at once.

Reviewer Insights on the Minisforum AtomMan G1 Pro

Video Review Highlights

ETA PRIME’s review framed the G1 Pro as a small-form-factor PC that finally puts down “really great performance,” praising the sleek vertical design and the internal 350W supply that eliminates the external brick. The disassembly and benchmark run confirmed strong 1440p gaming results, but the reviewer flagged the single-DIMM memory configuration as a real weakness: “with RAM prices right now, I’ve been seeing this quite a bit from mini PC manufacturers, only adding one DIMM instead of two,” noting that single-channel memory hurts performance in some workflows. GPU temperatures stayed comfortable at 65 to 70 Celsius during gaming, while the CPU ran hot under the most aggressive power profile.

Robtech’s hands-on review was even more enthusiastic about the design, calling it “the best-looking device Minisforum has released. Period.” The teardown reinforced the central appeal of the machine, an “interesting mix of mobile CPU and desktop GPU,” but also surfaced two concerns. To the reviewer’s surprise, the test unit shipped with only a single 32GB Crucial stick, and Windows Defender flagged the bundled RGB lighting driver for security vulnerabilities. Fan noise under load measured a noticeable 47 to 50 dBA, and accessing the RAM required removing the CPU cooler.

Britec09 went the furthest, describing the G1 Pro as “probably the best mini PC that I’ve reviewed on this channel” and “an absolute beast.” The review leaned into the desktop-replacement angle, highlighting the dedicated RTX 5060, the internal 350W supply, the dual SODIMM and dual M.2 slots, and a cooling system built around five copper heat pipes. The reviewer’s main caveats were practical: the processor is soldered and not upgradeable, the footprint is larger than a traditional micro mini PC, and the test unit again shipped single-channel.

In a follow-up, ETA PRIME explored the G1 Pro as a workstation by swapping the stock RTX 5060 for an Intel Arc Pro B50 with 16GB of VRAM, taking advantage of the internal 8-pin PCIe connector and support for low-profile dual-slot cards. The result was “actually pretty awesome” for local AI work, where the extra VRAM let the machine run larger language models, though the reviewer was clear that the RTX 5060 remains the better pick for gaming. The takeaway across all four reviews is consistent: the G1 Pro is genuinely flexible, but buyers should plan on adding a second memory stick to unlock its full potential.

Manufacturer Positioning

Minisforum’s own product announcement positions the G1 Pro as delivering “uncompromising desktop-caliber performance in a footprint small enough to fit virtually any workspace,” with the vertical chassis “inspired by next-gen consoles.” The company emphasizes the integrated power supply that “eliminates the need for bulky external bricks,” the 300W-rated cooling, native support for up to four displays, and the WiFi 7 plus 5GbE connectivity. As a manufacturer press release rather than an independent review, those claims are best read alongside the hands-on testing above, which broadly confirmed the performance story while adding the single-channel memory and thermal caveats.

Customer Reviews of the Minisforum AtomMan G1 Pro

The AtomMan G1 Pro is a recent release, and customer feedback on Amazon is still limited, with only a handful of early ratings posted so far. That means there is not yet enough volume to draw firm conclusions about long-term reliability or unit-to-unit consistency, so the most useful signal at this stage comes from the detailed video teardowns and benchmark runs rather than aggregate star counts.

The early impressions that do exist track closely with the reviewer consensus. Buyers drawn to the machine cite the same strengths the reviewers did: a genuine desktop GPU in a compact tower, the clean cable story enabled by the internal power supply, and quiet operation in the lower power modes. The recurring point of caution is the memory configuration, with owners echoing the advice to add a second SODIMM to run the system in dual-channel.

As more units reach desks, the customer picture should fill out. For now, anyone considering the G1 Pro is best served by treating it as a known quantity on performance, where the hardware and testing are well documented, while keeping expectations measured on the data points that only time and volume can establish.

Conclusion

The Minisforum AtomMan G1 Pro is one of the more compelling small-form-factor gaming PCs to arrive in a while, precisely because it refuses to compromise on the graphics card. Where most mini PCs reach for a power-limited laptop GPU, the G1 Pro drops in a low-profile desktop RTX 5060 and feeds it from an internal 350W supply, then backs it with a 16-core Ryzen 9 8945HX and modern connectivity in WiFi 7 and 5GbE. For 1440p gaming, video rendering, and local AI experimentation, it behaves like a real desktop that happens to fit in 3.8 liters.

The reservations are worth taking seriously. The single-channel memory configuration out of the box leaves performance on the table until you add a second stick, the CPU runs hot and the fans get loud under the most aggressive power mode, and the bundled RGB software has raised security flags that are easy enough to avoid by simply not installing it. There is also no USB4 or Thunderbolt, which may matter to anyone planning fast external storage or docking. None of these are dealbreakers for the target buyer, but they shape who the machine is for.

If you want desktop-class gaming and creator performance without building or housing a full tower, and you are comfortable popping in a second memory stick on day one, the AtomMan G1 Pro is an easy recommendation.
