Minisforum AtomMan G1 Pro

SFF Gaming PC — AMD Ryzen™ 9 8945HX + NVIDIA GeForce RTX 5060 Desktop

The Minisforum AtomMan G1 Pro is a machine that forces a reconsideration of what a mini PC is allowed to be. PC Gamer awarded it 86/100 and described it as “a weird hybrid of sorts, fluidly blurring the lines between a mid-range gaming laptop and an entry-level ITX rig.” Tom’s Guide called it “the perfect mini PC for ditching your console.” In a 3.8-litre chassis smaller than a PlayStation 5, Minisforum has installed a 350-watt internal power supply, AMD’s 16-core Ryzen 9 8945HX Dragon Range processor, a genuine desktop NVIDIA GeForce RTX 5060 GPU with 8 GB of GDDR7 memory, dual DDR5 SO-DIMM slots supporting up to 96 GB, two M.2 PCIe 4.0 ×4 storage slots, 5 Gigabit Ethernet, Wi-Fi 7, and five display outputs across HDMI 2.1 and DisplayPort 2.1.

Two important clarifications before purchase. First, the Ryzen 9 8945HX is a Dragon Range processor without an NPU — the G1 Pro is not a Copilot+ PC and does not support Windows 11 AI features. Second, PC Gamer’s review flagged the USB port count as the machine’s most significant practical limitation: with only five USB ports total across front and rear, a USB hub is essentially a required accessory for any user with more than a keyboard and mouse to connect.

Processor — AMD Ryzen™ 9 8945HX: Dragon Range, 16 Zen 4 Cores at 5.4 GHz

The Ryzen 9 8945HX is AMD’s Dragon Range Refresh processor — a dual-CCD mobile chip using the same Zen 4 architecture as the desktop Ryzen 9 7950X, packaged for mobile thermal envelopes and manufactured on TSMC’s 5 nm process. With 16 cores, 32 threads, and a boost frequency of 5.4 GHz, it is AMD’s most capable laptop/compact desktop processor outside of the Strix Halo series. The 8945HX has no NPU, but its dual-CCD architecture delivers exceptional multi-threaded throughput that exceeds the Strix Point platform in sustained workloads.

Minisforum’s desktop application controls the CPU’s power allocation through three profiles. Office Mode at 60W provides cool and quiet operation for productivity. Gaming Mode increases to 80W, improving sustained CPU clocks during gaming. Beast Mode pushes to 100W, extracting maximum performance above the chip’s official 55–75W rating. A critical operational note: the GPU operates at its full 120W regardless of which CPU profile is selected — switching modes affects only CPU performance, not GPU performance. In PC Gamer’s Beast Mode testing, Cinebench 2024 multi-core reached 1,323 points. CPU temperatures during gaming averaged 89°C and peaked at 93°C in computational tests — hot, but within the 100°C TJMax specification.

• 16 cores / 32 threads (Zen 4 — Dragon Range Refresh, dual-CCD)
• Base 4.0 GHz — Boost up to 5.4 GHz
• L2 Cache: 16 MB | L3 Cache: 32 MB (dual CCD)
• 5 nm TSMC process node
• TDP: Office 60W / Gaming 80W / Beast Mode 100W
• No NPU — not a Copilot+ PC

GPU — NVIDIA GeForce RTX 5060 Desktop: Blackwell, DLSS 4, 8 GB GDDR7, User-Replaceable

The RTX 5060 in the G1 Pro is not a laptop GPU. A low-profile Gigabyte RTX 5060 OC Desktop edition — carrying 8 GB of GDDR7 memory and NVIDIA’s Blackwell architecture — is installed in a PCIe 4.0 ×16 slot and powered at a locked 120W TDP from the internal 350W PSU. The desktop variant operates at a higher sustained power limit than any laptop RTX 5060, and because it occupies a standard PCIe slot, it can be replaced by future low-profile GPU generations when they become available.

In PC Gamer’s 1440p gaming benchmarks: Cyberpunk 2077 at Ray Tracing Medium runs at 32 FPS natively, rising to 86 FPS with DLSS Quality + Frame Generation ×2. Baldur’s Gate 3 delivers 59 FPS on Ultra. Metro Exodus Enhanced Edition reaches 52 FPS on Ultra. Avatar: Frontiers of Pandora achieves 44 FPS on Ultra. Black Myth: Wukong reaches 37 FPS with upscaling. In 3DMark Time Spy Extreme, the G1 Pro posted 6,705 overall — significantly ahead of the Bosgame M5’s integrated Radeon 8060S (5,312). GPU temperatures averaged 77°C and peaked at 67°C in computational tests.

Integrated PSU — 350W, No External Brick, Standard IEC Cable

The 350-watt internal power supply is the engineering decision that defines the G1 Pro most distinctly from every other mini PC on this website. A standard IEC power cable plugs directly into the rear of the chassis — identical to connecting a desktop PC or gaming console. With CPU at 100W and GPU at 120W simultaneously, total system draw is approximately 220–240W, leaving the PSU with over 100W of headroom. Tom’s Guide highlighted this as a feature shared only with Apple’s Mac mini M4 among mini PCs tested. The internal PSU also enables genuine portability — the machine travels with a single, cheap, universally available IEC cable.

Memory — Up to 96 GB DDR5, Fully Upgradeable SO-DIMM

Two DDR5-5200 SO-DIMM slots support up to 48 GB per slot for a maximum of 96 GB. The standard 32 GB configuration is adequate for gaming and most creative workloads. Both slots are accessible for user upgrades — along with the GPU and both M.2 slots, making the G1 Pro one of the most comprehensively upgradeable compact gaming systems available.

Storage — Dual PCIe 4.0 ×4 with Included M.2 Heatsink

Two M.2 2280 PCIe 4.0 ×4 slots deliver sequential read speeds exceeding 6,000 MB/s. The primary slot ships with a 1 TB Kingston NVMe SSD. The secondary slot is empty, and Minisforum includes a dedicated M.2 heatsink for it in the box — a detail PC Gamer specifically praised as “a genuinely nice touch” that prevents thermal throttling on high-performance drives installed post-purchase. Maximum combined capacity is 16 TB.

Display Outputs — Five Ports, Quad Simultaneous, DP 2.1

Five video output ports — two HDMI 2.1 (4K@144Hz), two DisplayPort 2.1 (8K@60Hz / 4K@165Hz), and one DisplayPort 1.4 — enable up to four simultaneous displays. The DisplayPort 2.1 outputs are a step above the DP 1.4 found in most competing mini PCs, providing higher refresh rates at 4K and native 8K support for future-proofing.

Connectivity — 5 GbE, Wi-Fi 7, Limited USB Ports

A 5 Gigabit Ethernet port delivers twice the bandwidth of the 2.5 GbE ports found in most competing mini PCs. Wi-Fi 7 (802.11be) with Bluetooth 5.4 provides tri-band wireless. However, the USB port count is the G1 Pro’s most consistently criticised specification: three USB Type-A and two USB Type-C ports total across front and rear. PC Gamer, Tom’s Guide, and Starry Hope all flagged this as a practical inconvenience requiring a USB hub for any user with multiple peripherals.

Thermal Performance — Hot CPU, Efficient GPU

Five copper heat pipes and multiple 3,600 RPM fans exhaust through dual side vents. CPU temperatures during gaming averaged 89°C in Beast Mode — high but within specification. GPU temperatures were substantially more comfortable at 77°C average during gaming and 67°C peak in computational tests. Fan noise under heavy load is audible. At idle, the system is quiet at CPU 51°C and GPU 38°C.

Design — PS5-Inspired, Vertical Stand Included, Portable

The slim vertical chassis — 215 × 57 × 315 mm — evokes next-generation gaming consoles deliberately. The vertical stand screws onto the bottom via thumb screw. At 3.81 kg, the G1 Pro is substantially heavier than conventional mini PCs but lighter than any gaming tower offering comparable GPU performance. Tom’s Guide noted fitting it in a backpack for transport. The GPU, RAM, and storage are all serviceable for future upgrades — a key design differentiator from sealed systems.
