The FEVM RTX 5090 mini PC lineup has arrived in two flavours, the FA80G and FN80G, both squeezing desktop-class processors and Nvidia’s most powerful mobile graphics chip into a chassis smaller than a shoebox. FEVM, a relatively new name in the small-form-factor space, is chasing the same trend that has pushed several manufacturers to cram full-fat gaming hardware into cases that once only held basic mini PCs for browsing and office work.
The FA80G runs on AMD silicon, topping out at a Ryzen 9 9950X3D, while the FN80G swaps in Intel, going as high as a Core Ultra 7 270KP. Both can be configured with an Nvidia GeForce RTX 5090 Mobile GPU, and both fit that hardware into a 2.6-litre enclosure measuring just 180 by 168 by 88 millimetres. That is a remarkably small footprint for components that would normally demand a full tower case with dedicated airflow channels.

What’s inside the FA80G and FN80G
Both machines start from a more modest baseline than the headline configuration suggests. The entry point for each is Nvidia’s RTX 5060, with buyers able to step up through a desktop RTX 5060 Ti or an RTX 5080 Laptop GPU before reaching the flagship RTX 5090 Mobile option. That range gives FEVM a genuine ladder of price and performance tiers rather than a single showcase build that most people will never actually configure.
In the RTX 5090 Mobile variant, the GPU is capped at 150 watts, with combined CPU and GPU power draw limited to 250 watts across the whole system. That is a considerable power budget for a case this size, and it explains why FEVM has put so much emphasis on the cooling design rather than just the component list.
| Model | CPU options | GPU options | Chassis volume |
|---|---|---|---|
| FEVM FA80G | Up to AMD Ryzen 9 9950X3D | RTX 5060 up to RTX 5090 Mobile | 2.6 litres |
| FEVM FN80G | Up to Intel Core Ultra 7 270KP | RTX 5060 up to RTX 5090 Mobile | 2.6 litres |
Neither model ships with memory or storage installed. Both are sold as barebones units, meaning buyers need to supply their own RAM and SSDs before the system is usable, a common approach among boutique mini PC builders that lets them offer a wider range of configurations without holding excess stock of every memory and storage combination.
Cooling and noise inside a tight chassis
FEVM claims its cooling solution keeps the CPU below 85 degrees Celsius and the GPU below 80 degrees Celsius under load, while staying under 42 decibels of fan noise. Those are respectable figures for hardware pulling up to 250 watts combined, particularly given how little internal volume there is to move air through and dissipate heat.
Thermal management is arguably the harder engineering problem in a build like this, more so than simply sourcing a desktop CPU and a mobile GPU. Cramming components this powerful into 2.6 litres leaves little room for airflow, and any shortfall in the heatsink or fan design shows up quickly as thermal throttling, which would undercut the entire point of fitting a 9950X3D or RTX 5090 Mobile into the box in the first place.
How the FA80G and FN80G stack up
FEVM is not new to this category. The company previously released the FAEX1, a mini PC built around AMD’s Ryzen AI Max 395 chip, better known by its Strix Halo codename, fitted into a one-litre enclosure. That earlier machine leaned on an integrated GPU for its graphics performance, whereas the FA80G and FN80G take a different approach entirely, pairing desktop or high-end mobile CPUs with a genuine discrete GPU capable of RTX 5090-class performance.
That shift puts these new models in more direct competition with other small-form-factor gaming rigs rather than the ultraportable mini PC crowd. Other mini workstation makers have gone down a similar path, chasing desktop-grade performance in shrunken cases, and RTX 5090 pricing has already been climbing well above MSRP on the desktop card itself, which makes the mobile variant an interesting alternative for buyers who want similar graphics horsepower without competing for scarce desktop cards. AMD’s own Ryzen AI Halo push at IFA 2026 shows how seriously the chipmaker is taking this compact high-performance segment, and Acer’s small-form-factor RTX Spark desktop is chasing a comparable audience from a different angle.
What it means for buyers
The barebones format means the FA80G and FN80G will suit builders who already have spare DDR5 memory and an NVMe SSD sitting around, or those who want to pick a specific speed and capacity rather than accept whatever a manufacturer bundles in. It also means the final price and performance depend heavily on what gets installed, so shoppers will need to budget for memory and storage on top of the base unit.
For anyone chasing genuine gaming or content creation performance in a footprint that fits on a shelf rather than under a desk, the FA80G and FN80G represent a meaningful step up from typical mini PCs, most of which rely on integrated graphics. Whether the cooling claims hold up under sustained load in real-world reviews remains to be seen, but on paper, FEVM has built one of the more ambitious compact systems to combine a full desktop CPU with Nvidia’s flagship mobile GPU silicon.
