Minisforum AtomMan G1 Pro Review

Overview

Here is the problem the Minisforum AtomMan G1 Pro exists to solve: you want to game at 1440p in a living room, dorm, or small apartment where a 40-liter tower is unwelcome, you don't want a laptop's thermal compromises, and you don't want to build it yourself. Minisforum's answer is a 3.85-liter white slab — smaller than a PS5 standing on its side — containing a 16-core desktop-class Ryzen 9 8945HX, a genuine desktop GeForce RTX 5060, 32 GB of DDR5, and an internal 350 W power supply. No power brick, no proprietary anything, no console walled garden.

It arrives into a suddenly crowded gaming-systems category: Valve's $1,049 Steam Machine has made "small PC for the living room" a mainstream idea, and DIY Bazzite boxes undercut everything at the bottom. The G1 Pro's pitch against both is Windows flexibility with console footprint — and per PC Gamer, which scored it 86/100, it "captures an impressive amount of performance for a remarkably reasonable price." CNET was more measured at 7.6/10, arguing bigger towers and similarly-priced laptops beat it on raw value. Both, again, are right.

Pricing at launch: $1,799 fully configured (Ryzen 9 8945HX, RTX 5060, 32 GB DDR5-5200, 1 TB PCIe 4.0 SSD, Windows 11 Pro) or $1,299 barebones. Early-bird promos dipped under $1,450, and the RTX 5060 configuration currently lists on Amazon at 4.4 stars from 18 ratings. There's also a sibling SKU with a Radeon RX 9060 XT 16 GB at the same money — this review covers the RTX 5060 build PC Gamer and CNET tested.

Design and build: PS5 cosplay, competent execution

The G1 Pro is a white plastic frame wrapping a black core, with two RGB light bars on the front and a curve that drops down like a PS5 that went on a diet. It's 215 × 57 × 315 mm — genuinely console-adjacent, though "somewhat large for a mini PC" by CNET's reckoning next to Minisforum's own smaller boxes. A bundled stand holds it vertically, which is clearly the intended orientation; laid on its side, the logos end up upside down. The extra volume buys things small mini PCs can't have: a thick CPU cooler, an internal PSU instead of a brick, and a PCIe 4.0 x16 slot holding a real desktop graphics card.

That card is the trick of the whole machine: a Gigabyte RTX 5060 OC Low Profile — a three-fan card that's a fraction of the size of a normal one-fan model. It's a desktop GPU running a full 145 W, not the cut-down mobile part you'd find in a gaming laptop or most mini PCs at this size. The trade-off is baked in forever: if you ever want to swap it, replacements in this low-profile niche are nearly unfindable. Treat the GPU as fixed; upgrade the rest.

Inside, the layout is cramped but tidy — cables secured, cooling well-positioned, and two M.2 slots, one filled by a 1 TB Kingston PCIe 4.0 drive, the other empty with a spare heatsink included, which is a genuinely thoughtful touch. RAM is SO-DIMM, so 32 GB is not a ceiling. PC Gamer rated build quality "very good" and aesthetics "top-tier."

Performance: a 16-core CPU in a console costume

The Ryzen 9 8945HX is a laptop-derived Zen 4 chip — 16 cores, 32 threads, boosts to 5.4 GHz — and in a chassis this size it's borderline exotic. In Cinebench R24's multi-core test, CNET measured it outpacing a desktop Ryzen 7 7800X3D (as configured in Lenovo's Legion Tower 5). It trails Intel HX laptops in single-thread punch, but for a machine this size, the multitasking headroom is absurd: PCMark 10 landed at 9,066 points, territory usually reserved for full-size gaming rigs. Streaming, compiling, forty Chrome tabs, and a game simultaneously? Non-issue.

Gaming is where nuance enters. Out of the box, the G1 Pro defaults to Minisforum's "Gaming Mode" (80 W CPU), and in that mode it performs in line with RTX 5060 laptops — the HP Omen 16, Lenovo LOQ 15 — while trailing Legion-class machines and even Minisforum's own thinner G7 Ti with a mobile RTX 4070. That sounds damning until you learn why: the 60 W "Office," 80 W "Gaming," and 100 W "Beast" modes are one click away in Minisforum's app, and Beast Mode transforms the machine. CNET measured +20% in 3DMark Time Spy, +38% in Steel Nomad, and +26% in Shadow of the Tomb Raider — enough to catch and pass the G7 Ti and match Lenovo's Legion 5i Gen 10. In practice: solid 1440p gaming, triple-digit framerates at 1080p, with the 8 GB of VRAM the honest ceiling for texture-heavy titles at 1440p ultra.

So the real out-of-box performance problem isn't silicon — it's that the default profile hides a fifth of the machine's capability, and you only get it if you know the toggle exists. (CNET also found Windows Defender quarantining Winring0, a vulnerable legacy driver inside Minisforum's own utility software; performance modes then all ran at Beast levels regardless of setting. Minisforum needs to ship a patched app, full stop.)

Thermals and noise: the tax on 3.85 liters

Physics sends a bill. PC Gamer logged an average CPU temperature of 89 °C in gaming with peaks at 91 °C in consecutive Metro Exodus runs, and 93 °C in compute workloads — toasty against the chip's 100 °C TJmax, though within spec and sustained without throttling drama. The RTX 5060, ironically, is the well-behaved one: 67 °C in Blender, averaging 77 °C in-game, with obvious headroom left on the table. Fan noise stays "quiet enough" per PC Gamer even in Beast Mode — the G1 Pro is audible but never obtrusive, a reasonable trade for this density.

Placement matters: this is a machine that breathes through its shell. Give it open air, don't bury it in a cabinet, and use the vertical stand.

I/O and software: bring a hub

Here's where the budget went missing. Total connectivity: two USB-C (one front, one rear), three USB-A (one front, two rear), a 3.5 mm combo jack, 5 Gb Ethernet, plus display outputs (2× HDMI 2.1, DisplayPorts off the GPU). That's thin for a desktop replacement — a keyboard, mouse, headset dongle, and one external drive consumes everything. Both PC Gamer and CNET independently arrived at the same advice: budget for a USB hub. Networking is the counterweight: Wi-Fi 7 and 5 GbE are a class above what consoles and most mini PCs offer.

The software story is Windows 11 Pro, untouched, plus Minisforum's own app for the three power profiles, fan curves, and RGB — and that app is the weakest link (see the Winring0 issue above). The one firm rule of ownership: switch to Beast Mode on day one and forget Gaming Mode exists.

Value: against towers, laptops, and the Steam Machine

At $1,799 the G1 Pro occupies awkward ground. CNET's comparisons are fair: Lenovo's Legion Tower 5 Gen 10 ($2,100, 42.7 L) and Dell's Tower Plus ($2,380, 27.5 L) both fit desktop RTX 5070s and decisively out-game it per dollar. A DIY ITX build at this price would outperform it. A $1,049 Steam Machine undercuts it by $750 with a slicker living-room OS (though with weaker hardware and a closed ecosystem). But every one of those alternatives is bigger, or needs building, or locks you out of Windows — and none fits in a backpack with a stand and plays everything. If the constraint is volume, the comparison set shrinks to almost nothing, and the G1 Pro wins what's left. The barebones $1,299 SKU is the value pick for anyone with spare RAM, an SSD, and a Windows license lying around.

Pros

• 3.85 L with an internal 350 W PSU — console footprint, desktop GPU, no power brick
• Ryzen 9 8945HX: 16C/32T that beats a 7800X3D in multi-core; PCMark 10 of 9,066
• Genuine desktop RTX 5060 at 145 W — triple-digit 1080p, solid 1440p gaming
• Beast Mode is a free +20–38% performance uplift once enabled
• Real upgrade path on storage and RAM: second M.2 slot with included heatsink, SO-DIMM memory
• Wi-Fi 7 + 5 GbE, quiet under load, tidy internals, bundled vertical stand

Cons

• Defaults to 80 W Gaming Mode — a fifth of the performance hides behind a manual toggle
• CPU runs hot: 89 °C average in gaming, 93 °C peaks in compute
• I/O is sparse; a USB hub is effectively mandatory
• Minisforum utility ships the vulnerable Winring0 driver (Windows Defender flags it)
• $1,799 undercuts the value of bigger RTX 5070 towers and DIY builds; GPU not realistically swappable
• Windows-first experience: no SteamOS polish for couch use

Verdict

8/10 — Very good. The AtomMan G1 Pro is the rare mini PC that doesn't apologize for itself: desktop-class silicon, real gaming performance, and genuine upgradeability in a body that genuinely belongs next to a TV. Enable Beast Mode, add a USB hub, and it's a 1440p gaming PC you can carry in a tote bag. Just know that if desk space isn't the constraint, $1,799 buys more frames elsewhere.
