- The Miniforum AtomMan G1 Pro packs a desktop GPU into a space-thermally challenged chassis
- Four 4K displays combine signal routing and thermal stability
- The vertical airflow theory seems valid as long as dust is not collected on a daily basis.
The Minisforum AtomMan G1 Pro mini PC is based on an AMD Ryzen 9 8945HX and an RTX 5060 desktop GPU, a combination usually reserved for much larger systems.
On paper, the device is at the lower end of traditional workstation performance, making it suitable for AAA games and simple 3D workloads.
The AtomMan G1 Pro has a 350-watt power supply, which suggests that headroom is limited when the CPU and GPU are under prolonged load.
Strict thermal limits
Cooling is provided by a vertical airflow system with large fans, copper heat pipes and dual exhaust ducts.
Minisforum specifies that the heat dissipation is about 300 watts, a value that leaves little room for inefficiency or aging of the components.
In compact systems, thermal throttling is more likely to occur at long workloads than at short benchmarks, making it difficult to predict actual performance based on specifications alone.
The system offers multiple DisplayPort and HDMI outputs and supports up to four 4K displays.
This setup is intended for editing, development and simulation purposes where screen space is important.
USB ports include USB-A and USB-C ports split between front and back, as well as audio access and a wired 5GbE network port.
This configuration meets the needs of gaming, publishing, and development environments that rely on multiple devices and high-speed networks.
However, compact systems often share internal controls across multiple ports, which can cause bandwidth limitations when concurrent workloads are high.
The inclusion of multiple high-resolution display outputs increases the pressure on internal routing when all interfaces are active at the same time.
At this scale, even small disturbances in airflow can affect overall reliability, which is likely to be a disadvantage.
The device uses a vertical white tower shape with a wavy textured side panel and a narrow strip of light on the front.
The front I/O is located along a single edge to reduce surface interference. The vertical design reduces desk space and ensures that the hardware remains visible instead of hidden.
This design is a departure from the familiar discrete form factor of mini-computers and is based on the design of compact speakers or audio devices.
While this visually suits mixed living and working spaces, the vertical design also concentrates heat into fewer exhaust areas.
