FEVM Packs a 150W RTX 5090 Laptop GPU Into a 2.6 Liter Mini PC [2026]

By Indie Kings | October 2, 2026

Updated October 2, 2026: FEVM is listing a pair of 2.6 liter desktop-class mini PCs that carry NVIDIA laptop GPUs, including an RTX 5090 Laptop GPU 24GB configuration rated at up to 150W. The FN80G runs Intel Core Ultra 200S desktop chips and the FA80G runs socketed AM5 AMD Ryzen desktop chips, so the GPU is the mobile part in both cases.

Two Chassis, One Approach

FEVM has been building desktop CPU plus mobile GPU machines since the 2.5 liter FN60G that this blog covered in 2023. The idea has stayed consistent across three years: take a full size desktop processor, which needs socketed memory, socketed storage, and a real power delivery stage, then pair it with a laptop graphics card, which is short, cool, and dense, and compress the combination into a small box. The FN80G and FA80G are the current expression of that idea, and both are listed on JD.com at up to 2.6 liters.

Per VideoCardz by WhyCry on September 8, 2026 relaying FEVM listings on JD.com, the FN80G measures 180 by 168 by 88 mm, which works out to about 2.6 liters, and spans Intel Core Ultra 200S desktop processors from the Core Ultra 5 230F up through the Core Ultra 7 270KP. The FA80G is the socketed AMD sibling on AM5, listed with the Ryzen 7 9700X, the Ryzen 7 7800X3D, the Ryzen 7 9800X3D, and the Ryzen 9 9950X3D.

That CPU range matters because it is the opposite of how most small form factor PCs are built. Most mini PCs use soldered laptop processors with shared memory and a single storage slot, which keeps them cheap and quiet but caps them at lower power and lower upgradeability. These two chassis take desktop silicon, so they get two SO-DIMM slots, two full length NVMe slots, and desktop class I/O including 10GbE on the Intel model. The cost is a bigger power draw than a typical mini PC and a harder thermal problem, since desktop processors are not designed for a 2.6 liter enclosure.

The AMD side is arguably the more interesting of the two, because the listed Ryzen options include two of the strongest gaming chips on the market, the 7800X3D and the 9800X3D, and one enthusiast flagship in the 9950X3D. A small chassis that accepts a 9950X3D is a statement about component density rather than about gaming value. The Intel side is the more balanced one for productivity, with faster integrated graphics on the higher end Core Ultra parts and the only Thunderbolt 4 plus 10GbE combination in the lineup [NEEDS VERIFICATION].

Nothing in the verified material describes operating system support, warranty terms, chassis material, or shipping outside China [NEEDS VERIFICATION]. FEVM is a China based brand with a China focused retail channel, so import cost, warranty service, and availability of the exact barebone SKU in other markets are all open questions. Treat the listed prices as China domestic pricing, not as what you will pay delivered to your door.

The GPU Options

Per VideoCardz by WhyCry on September 8, 2026 relaying FEVM listings on JD.com, both chassis are offered with four NVIDIA laptop GPU options: the RTX 5060 8GB, the RTX 5060 Ti 16GB, the RTX 5080 Laptop GPU 16GB, and the RTX 5090 Laptop GPU 24GB. The naming is the clearest part of the story. These are mobile GB202, GB203, and GB205 class dies in a desktop style enclosure, not desktop RTX cards.

That has real advantages and real costs, and buyers should hold both in mind. On the advantage side, laptop GPUs ship with power limits already tuned for thin enclosures, so a 150W cap on an RTX 5090 Laptop GPU 24GB inside 2.6 liters is a conservative ask by desktop standards. They are also physically small, which is why the layout works at all. On the cost side, mobile memory is frequently GDDR7 on a narrower bus, laptop power delivery is leaner, and there is no desktop sized cooler, so sustained performance will not match a desktop RTX 5090 in a tower even though the name on the badge is identical [NEEDS VERIFICATION].

On power, the verified listing states that the RTX 5090 configuration runs up to 150W, and that FEVM claims up to 250W combined for CPU plus GPU on that configuration. The FA80G listings state up to 90W for the CPU and up to 150W for the GPU. A 250W combined ceiling in a 2.6 liter box is the single boldest engineering claim in this announcement, and it is a manufacturer claim rather than an independent measurement [NEEDS VERIFICATION]. No independent thermal, noise, or performance testing of either chassis was available at the time of the VideoCardz report.

Readers searching for this hardware tend to use phrases such as FEVM FN80G, FEVM FA80G, RTX 5090M mini PC, RTX 5090 laptop GPU 150W, 2.6 liter mini PC RTX 5090, FEVM mini PC price, and AM5 mini PC RTX 5080M. Those queries all land on the same structural question, which is not whether a 5090 can fit, but whether a 5090 at 150W can be kept quiet and cool while a desktop CPU runs beside it.

Cooling And The 42 dB Claim

Per VideoCardz by WhyCry on September 8, 2026 relaying FEVM listings on JD.com, both systems use separate four heatpipe assemblies, one per chip, for eight heatpipes in total. FEVM claims 42 dB at full load with the CPU under 85C and the GPU under 80C. Those are the numbers to argue with, and the arguing should be precise about what they are and are not.

What they are: a manufacturer specification. FEVM is describing its own chassis running its own internal test, and the phrasing of a combined temperature and noise figure like that almost always refers to a controlled internal workload rather than a consumer mix of gaming, compiling, and idle time. There is no published ambient temperature, no fan curve, no measurement distance, no microphone standard, and no workload definition in the verified material [NEEDS VERIFICATION].

What they are not: a promise that your machine will be silent. 42 dB measured at close range on a desk is audible in a quiet room, and laptop GPUs and desktop CPUs under sustained load will need fans to maintain the claimed temperatures. Buyers in genuinely quiet spaces, such as a recording room or a bedroom office, should treat any published figure for this class of hardware as a starting point for comparison rather than a comfort guarantee [NEEDS VERIFICATION].

The separate heatpipe design is the most sensible part of the thermal story. Because the CPU and GPU do not share a single heatsink, neither chip has to fight the other for the same metal, and the GPU cooler can be sized to the laptop card rather than to a compromise shape. Eight heatpipes in 2.6 liters is ambitious, and it also implies a power supply and fan wall that leaves little margin [NEEDS VERIFICATION]. The failure modes to watch for in independent reviews are sustained thermal throttling under long CPU loads, fan pitch under mixed workloads, and coil noise, which becomes more likely when small high speed fans drive small heatsinks.

Memory, Storage, And Ports

Both chassis, per VideoCardz by WhyCry on September 8, 2026 relaying FEVM listings on JD.com, support up to 128GB of DDR5 across two SO-DIMM slots, and both provide two M.2 2280 NVMe slots with official support up to 4TB each plus one M.2 2230 wireless slot. Two SO-DIMMs and two full length NVMe drives is the spec sheet of a small desktop, not a mini PC, and it is the clearest signal that these are reduced size desktops rather than thin clients.

The port lists separate the two models. The FN80G lists Thunderbolt 4, 10GbE, and 2.5GbE, which makes it the better fit for a workstation with fast external storage or a multi display desk. The FA80G lists dual 2.5GbE and no Thunderbolt. Both list HDMI 2.0, HDMI 2.1, two DisplayPort 2.0, USB-C, USB-A, an SD card reader, and audio. Native support for three or four displays plus a laptop GPU is unusual in this chassis class and matters for anyone who does not want to add a graphics card later [NEEDS VERIFICATION].

Storage pricing deserves attention because 4TB NVMe drives are not cheap, and these are barebone systems. See the next section for what the listed prices do and do not include.

Barebone Pricing

Every price below is barebone, meaning no RAM and no storage, per VideoCardz by WhyCry on September 8, 2026 relaying FEVM listings on JD.com. The USD figures are VideoCardz conversions of the CNY list prices, not FEVM dollar pricing, and they move with exchange rates. The table lists every configuration named in the report.

Read the table as a curve, not as a menu. The 5060 8GB machines sit near 7,000 to 8,000 CNY, the 5060 Ti 16GB and 5080M 16GB tier sits near 13,000 to 14,400 CNY, and the 5090M 24GB configurations start at 19,999 CNY and reach 22,199 CNY. Roughly 12,000 CNY separates the entry card from the flagship, and 128GB of DDR5 plus two 4TB NVMe drives will add a substantial amount on top of any of these figures [NEEDS VERIFICATION].

The comparison that will generate the most argument is the flagship pair. The Core Ultra 7 270KP with RTX 5090M 24GB at 19,999 CNY, about $2,980, and the Ryzen 7 9800X3D with the same GPU at 20,399 CNY, about $3,039, land within 400 CNY of each other, so the platform decision is almost a tie on price and entirely about workload and preference [NEEDS VERIFICATION]. The Ryzen 9 9950X3D with RTX 5090M at 22,199 CNY is the most expensive configuration listed on either chassis.

How To Buy

The five steps below are written for someone with money in hand and a specific use case. They are ordered so that the expensive, hard to reverse decisions come first.

1. Pick the Intel or AMD chassis first. Choose the FN80G if you need Thunderbolt 4 or 10GbE, or if you prefer Intel platform features and the Core Ultra 7 tier. Choose the FA80G if gaming is the priority and you want the 7800X3D or 9800X3D options, or if you want a Ryzen 9 9950X3D flagship. Do not choose on the GPU, because both chassis offer the same four laptop GPU options [NEEDS VERIFICATION].
2. Pick the GPU tier second. The RTX 5060 8GB tier is the value entry, the RTX 5060 Ti 16GB and RTX 5080M 16GB tier is the mainstream sweet spot by price, and the RTX 5090M 24GB tier is the flagship. Remember that a laptop GPU at 150W is not the same as a desktop card of the same name, so compare laptop versus laptop, not laptop versus desktop [NEEDS VERIFICATION].
3. Check the 150W and 250W power claims before you commit. The RTX 5090 configuration runs up to 150W, and FEVM claims up to 250W combined CPU plus GPU, while the FA80G listings state up to 90W CPU and 150W GPU. Confirm the power supply rating for the exact SKU, confirm the wall socket and circuit you plan to use, and treat the 250W combined figure as a manufacturer claim until an independent reviewer measures it [NEEDS VERIFICATION].
4. Budget memory and storage separately. All listed prices are barebone, so add 128GB of DDR5 across two SO-DIMM slots and two M.2 2280 NVMe drives at up to 4TB each to your math before judging the total. A flagship 5090M machine that is 12,000 to 15,000 CNY cheaper once fully equipped is not actually cheaper [NEEDS VERIFICATION].
5. Wait for independent thermals and noise testing. The 42 dB figure and the sub 85C CPU and sub 80C GPU figures are FEVM claims, and no independent testing was available at the time of the VideoCardz report. Look for sustained load tests, fan noise at one meter, thermal throttling results, and coil noise commentary before you buy, especially if noise matters to you.

Step one is worth defending because it is the decision most people get backwards. Buyers fixate on the 5090 badge and only then look at the CPU list, when in practice the CPU choice determines the I/O, the memory behavior, and the upgrade path, and the GPU tier only determines which NVIDIA laptop chip you get [NEEDS VERIFICATION]. Step five is the one that protects you from disappointment. Nearly every number in this announcement that sounds spectacular is a manufacturer number, and the gap between a listed specification and a measured result in a 2.6 liter chassis is exactly where independent review earns its keep.

Is the 42 dB and under 85C claim verified?
No. Those are FEVM manufacturer claims with no independent testing available at the time of the report, so treat them as a reason to look for third party measurements rather than as a proven result [NEEDS VERIFICATION].

Bottom Line

FEVM has taken a formula it has been refining since the 2.5 liter FN60G in 2023 and pushed it into two new chassis. The FN80G pairs desktop Intel Core Ultra 200S chips with laptop NVIDIA GPUs in 2.6 liters, and the FA80G does the same on socketed AM5 with Ryzen 7 and Ryzen 9 silicon. The flagship configuration, an RTX 5090 Laptop GPU 24GB at up to 150W inside a 2.6 liter box next to a desktop CPU, is the headline, and the barebone pricing runs from 6,999 CNY to 22,199 CNY.

The appeal is real: two SO-DIMM slots, two full length NVMe slots, native multi display output, and in the FN80G a Thunderbolt 4 and 10GbE combination that no ordinary mini PC offers. The reservations are equally real. The 150W GPU figure, the 250W combined CPU plus GPU claim, and the 42 dB full load figure all come from the manufacturer, no independent testing existed when VideoCardz reported the listings, and the price list excludes memory and storage entirely.

If you want the density, wait for independent thermals and noise testing and budget the full configured price. If you want quiet, cheap, and upgradeable, this is not the machine.
