Minisforum has sold three different machines under the UM760 name since 2023, and that naming history is the first thing to untangle before buying one. The model most shoppers mean by "Minisforum UM760" is the UM760 Slim, the Ryzen 5 7640HS system introduced in September 2024 and still the practical entry point into the company's 6-core Ryzen range — a 0.67 kg box with two PCIe 4.0 M.2 slots, one physical 2.5GbE port and, in independent testing, an idle draw below 10 W at the wall. It sits in the volume tier of Minisforum's UM-series lineup, not at the flagship end.

At this tier the buying decision is rarely about peak CPU speed. A 6-core Zen 4 chip with a Radeon 760M handles a Plex library, a stack of Docker containers and a Windows desktop on a 4K panel comfortably. What separates a good sub-litre host from an irritating one is everything around the processor: how many Ethernet ports leave the chassis, whether the delivered memory is one module or two, whether the fan can be controlled at all, whether the integrated GPU can be handed to a virtual machine, and how many watts the machine burns every hour of every day.

This review works through those questions with measured numbers rather than marketing sheets. It covers wall power at idle and under load, sustained CPU temperature, fan noise, how the Radeon 760M's media engine behaves in Jellyfin versus Plex, what actually works under Proxmox and what does not, and the port layout that decides whether the machine can serve as a firewall.

It is written for anyone building an always-on node — media server, Home Assistant box, small virtualization host, backup target — and for buyers who need a compact Windows desktop and would rather not discover a workaround later. If you are still mapping the category as a whole, the homelab starter guide covers the topology questions that matter before model selection.

Minisforum UM760 Slim — Overview & First Impressions

The naming is the first trap. Minisforum has attached "UM760" to three separate products, all built around the same Ryzen 5 7640HS and Radeon 760M silicon, and the differences are chassis, ports and expansion rather than compute.

There is no UM760 configuration with a Ryzen 7 8845HS. Minisforum's own Plus-family selector maps 7640HS to UM760 Plus, 8745H to UM870 Plus and 8845HS to UM880 Plus, which means any listing advertising a "UM760 with 8845HS" is either mislabelled or a different product entirely.

What the Slim actually is, then, is a 6-core Zen 4 machine in a chassis small enough to sit on a VESA bracket behind a monitor. Two M.2 2280 PCIe 4.0 slots mean an OS drive and a data or transcode-cache drive can be kept separate without external enclosures. Both SO-DIMM slots are user-accessible, the Wi-Fi card is an M.2 2230 module rather than soldered silicon, and the 120 W adapter is a conventional 19 V barrel supply rather than a proprietary connector. For a machine intended to run for years, that combination matters more than a few hundred MHz of boost clock.

The first impression of the port layout is more ambivalent. HDMI 2.1, DisplayPort 1.4 and a USB4 port with DisplayPort output and 65–100 W power-delivery input cover display and docking duty well. One 2.5GbE port, however, is the single most consequential specification on the sheet for homelab buyers, and it recurs throughout this review.

Specs & What's in the Box

The retail box contains the mini PC, the 120 W 19 V / 6.32 A external adapter, and a mounting bracket for wall or VESA attachment. Buyers should read the SKU carefully before ordering, because Minisforum and Amazon both ship several memory and storage combinations from the same chassis, and the memory label differs between them.

The main configurations listed are 16 GB + 1 TB, 32 GB + 1 TB, 16 GB + 512 GB and 32 GB + 500 GB.

Barebone and wider configuration availability shifts between retailers: check the current UM760 Slim listings on Amazon.

Two details in that table are worth more attention than the capacity numbers. First, the official US 16 GB + 1 TB configuration is labelled DDR5-4800, even though the platform supports DDR5-5600 — so "16 GB" on a product page says nothing about the speed of the module inside. Second, owners have received both single-module and dual-module prebuilts from the same model line. On a machine whose integrated graphics borrow system memory as VRAM, one 16 GB module versus two 8 GB modules is a bandwidth difference, not a capacity difference, and it shows up in iGPU and media workloads long before it shows up in a file copy.

Build Quality & Durability

The chassis measures 130 × 126.5 × 50.4 mm and weighs roughly 0.67 kg, which puts it in the compact-but-not-ultra-compact class: small enough for a monitor arm, with enough internal volume for a real cooling stack. Inside, Minisforum uses a phase-change thermal interface on the CPU, three heatpipes, a main fan and dedicated airflow across the memory and SSD positions. That last detail is not cosmetic — dual PCIe 4.0 NVMe drives in a sealed half-litre box get hot, and the UM760 Slim is one of the few models at this size that actively cools them.

Serviceability is genuinely good for the class. Both DDR5 SO-DIMM slots are replaceable, both M.2 2280 slots are standard PCIe 4.0, and the Wi-Fi module is a socketed M.2 2230 card rather than soldered. There is a Clear CMOS control on the rear I/O for recovering from a bad memory or firmware state, which is a small thing that becomes a large thing the first time a memory training failure leaves the machine dark.

The one durability caveat is fan control. Independent testing found that the fan could not be driven by common third-party control software and that RPM was only readable inside the BIOS, which exposed no useful custom fan curve. The machine therefore cools itself on its own terms. Sustained behaviour is acceptable — measured CPU temperatures sit in the 35–50 °C range under ordinary office workloads and peak around 85 °C under heavy stress — but a buyer who expects to tune acoustics by hand should know that this platform does not offer that lever. Long-term reliability claims beyond that would be guesswork: there is no instrumented VRM temperature dataset for this model, and isolated hardware complaints do not establish a pattern.

Performance — Idle Watts, Sustained Load and the Media Engine

Measured power, thermals and noise

The measurements below cover wall power, thermals and noise across several test setups.

The spread between "under 9 W" and "15.7 W" is not a contradiction; it reflects Windows power state, attached peripherals, the RAM and SSD fitted, whether a display and network links are live, and the meter's own methodology. What the range does establish is the order of magnitude: this is an always-on host whose annual energy cost is dominated by idle behaviour, and whose idle behaviour is good.

Thermals and acoustics follow the same pattern. Office workloads keep the CPU around 35–50 °C, with a maximum near 85 °C under sustained stress. Fan noise measures roughly 30 dB during ordinary work and 42 dB(A) at maximum load in one test; a separate measurement at 50 cm recorded 32.3 dB idle, 33.2 dB while gaming and 36.9 dB under CPU load against a 31.1 dB background. Those figures are not directly comparable to each other because distance and ambient noise differ, but both describe a machine that is quiet in normal use and audible, not loud, when fully loaded.

One power-related behaviour deserves its own line. An owner test found that running the machine from a 65 W or 100 W USB-C power-delivery source produced lower peak consumption than the stock 120 W adapter — because the supply was constraining performance, not because it was more efficient. The 120 W brick is the reference configuration; a low reading obtained under a smaller PD supply is not an equivalent measurement.

What the Radeon 760M's media engine actually accelerates

The silicon capability is not in dispute. The Ryzen 5 7640HS media engine performs hardware H.264, HEVC and AV1 encode and decode, plus VP9 decode, so the hardware is present for modern codecs including AV1 output. Capability is where the certainty ends, because the application layer decides whether you get to use it.

Jellyfin is the friendly path for this platform. It supports AMD hardware acceleration through AMF on Windows and VA-API on Linux, documents AV1 encoding on Ryzen 7000 mobile APUs, and does not impose the artificial concurrent-encode-session cap that Nvidia cards carry. Two caveats apply: Jellyfin advises dual-channel memory for APUs precisely because the integrated GPU shares system memory bandwidth, and some rolling distributions ship Mesa VA-API builds with H.264 and HEVC support disabled, which the project's own container image avoids.

Plex is the harder path. Plex's documentation states that AMD hardware transcoding is supported "as is" and recommends Intel Quick Sync or Nvidia for a validated experience. Its experimental HEVC output encoding explicitly excludes AMD, and Plex normally hardware-encodes to H.264 where available. The practical consequence for a UM760 Slim owner is that the Radeon 760M does the work, but with less software validation behind it than the same silicon generation from Intel would have. The wider Plex requirements breakdown covers where those software paths typically break.

How many simultaneous transcodes the machine sustains is not something to quote as a number. Capacity depends on source codec and bitrate, HDR-to-SDR tone mapping, subtitle burn-in, whether the client can Direct Play the original file, and how the container is configured. The fixed-function media blocks handle the video work rather than the six CPU cores, which is exactly why a modest processor can serve several streams — but any figure presented as a fixed stream count for this specific model would be an inference rather than a measurement.

Linux, Proxmox and virtualization

Linux support on this exact model is real, with one hardware exception. A Tuxedo OS installation based on Ubuntu 24.04 ran successfully, including working standby. The MediaTek MT7902 Wi-Fi card, however, had no usable Linux driver in that test, and a separate owner account reached the same conclusion independently: replacing the M.2 2230 card with an MT7922 or an Intel AX210 resolved it. Wired Ethernet sidesteps the problem entirely, which is what a permanently installed server should be using anyway. Broader platform notes for this software tier are collected in the Ubuntu mini PC guide.

Proxmox itself runs. Owners have reported the UM760 Slim working as a Proxmox host with a Windows 11 virtual machine and with external storage planned for Jellyfin workloads. That is a normal hypervisor workload and the hardware is adequate for it.

Integrated GPU passthrough is a different claim, and it should not be assumed. In the exact-model report, the Radeon 760M could be exposed far enough for the AMD driver to appear inside the guest, but switching it into the intended primary-GPU position produced a black screen and loss of RDP access. There is no complete IOMMU group map published for this model and no reproducible full-passthrough recipe. If a service needs hardware transcoding, the reliable approach is to expose the render device to a container on the host rather than to assign the GPU to a virtual machine — the same pattern covered in the Proxmox host guide.

On the Windows side, one owner's powercfg /a output showed S0 Low Power Idle / Modern Standby rather than the traditional S3 sleep state, and other threads report fans or LEDs behaving unexpectedly during sleep and occasional failed wake cycles. These are community reports rather than a systematic behaviour, but anyone planning scheduled sleep cycles on a headless node should validate them on the delivered unit rather than assume S3 is available. Firmware V1.09 is published on Minisforum's support portal for the Slim; no public per-version changelog is provided, so no specific fix should be attributed to it.

Minisforum UM760 Slim vs GMKtec NucBox K8 Plus — Head-to-Head

The natural step up from the UM760 Slim for a homelab buyer is a Ryzen 7 8845HS machine with two network ports, and the GMKtec K8 Plus is the clearest example of that class.

The compute gap is real but rarely the deciding factor. Eight Zen 4 cores and twelve RDNA 3 compute units will transcode, virtualize and game better than six cores and eight compute units, and the Radeon 780M has meaningfully more graphics headroom. For a Plex or Jellyfin server that mostly Direct Plays, or a container host running Home Assistant, Pi-hole, a reverse proxy and a backup agent, that extra silicon sits idle most of the day.

Where the two machines genuinely diverge is topology. Two Intel 2.5GbE ports let the K8 Plus act as a real router or firewall with separate WAN and LAN interfaces, which a single port cannot do without VLANs on a managed switch. Native OCuLink gives a direct PCIe 4.0 ×4 path for external storage or a GPU, rather than the improvised M.2-to-OCuLink adapter route. The UM760 Slim answers with measured idle efficiency in a smaller chassis and a lower tier of the market — its advantage is running costs and footprint, not expansion.

If the workload is routing, PCIe expansion or more VM headroom, the step up is worth taking. If it is containers, media and a quiet always-on footprint, the UM760 Slim's single NIC stops mattering the moment a switch is already in the rack. The other UM-series option worth naming is the UM780 XTX — dual 2.5GbE, dual USB4 and OCuLink on the same chassis family — while the UM890 Pro adds a Ryzen 9 8945HS on top of that port set for buyers who need the core count.

Recommended Upgrades / Best Accessories

Memory: Crucial 32 GB DDR5-5600 SODIMM kit (CT2K16G56C46S5). A matched 2 × 16 GB kit is the single most useful change on a prebuilt that may ship with one module installed. Dual-channel bandwidth feeds the Radeon 760M directly, and a 16 GB Crucial DDR5-5600 pair has been used successfully in an actual UM760 Slim barebone. 96 GB is the official platform ceiling, so 2 × 48 GB is the maximum configuration. — Check price on Amazon

Storage: Crucial P310 1 TB M.2 2280 (CT1000P310SSD801). A real-world reference build runs a P310 1 TB alongside a second NVMe drive used for database, metadata and transcode cache. That split is the right instinct on a two-slot machine: keep the operating system and containers on one drive, and give Jellyfin or Plex's working files their own. — Check price on Amazon

Wi-Fi card for Linux: Intel AX210 or MediaTek MT7922, M.2 2230. Only relevant if the machine cannot be wired. The stock MT7902 module has no working Linux driver in independent testing, and both a lab test and a long-running owner account resolved it by swapping the card.

Power: use the supplied 120 W adapter. A 65 W or 100 W USB-C PD source will power the machine, but testing showed it reduces peak system draw — the supply is limiting performance, not saving energy.

Not recommended: an M.2-to-OCuLink adapter for eGPU use. It consumes one of the two storage slots, and the UM760 Plus already provides an official OCuLink path on an otherwise identical platform.

Frequently Asked Questions

Conclusion & Final Verdict

The UM760 Slim gets the fundamentals right. It idles below 10 W in independent testing, peaks just under 90 W under sustained CPU stress, keeps office-load temperatures in the 35–50 °C band and stays near 30 dB while doing ordinary work. Two PCIe 4.0 M.2 slots, two user-accessible DDR5 SO-DIMM slots, a socketed Wi-Fi card and a standard 120 W barrel adapter make it a machine that can be maintained rather than replaced. For a container host, a Jellyfin node or a compact Windows desktop, that is the right set of priorities.

Its constraints are equally specific, and they are architectural rather than fixable. One 2.5GbE port rules out a conventional firewall. There is no SATA bay, so a multi-drive NAS is out. Full Radeon 760M passthrough to a virtual machine ends in a black screen in the one exact-model report available. And the prebuilt memory lottery — a 16 GB configuration that may arrive at DDR5-4800 in a single module — means buyers should verify what they ordered or budget for a matched kit.

If you need dual NICs, OCuLink or more cores, the GMKtec K8 Plus or a UM780 XTX answers those needs directly. If you need a quiet, efficient, serviceable always-on Ryzen box for services that live on a network you already have, the UM760 Slim does that job well.
