Minisforum UM760 Slim Review: Compact Ryzen Performance (2026)

The Minisforum UM760 Slim is a 130 × 126.5 × 50.4 mm box — roughly 0.83 litres — built around exactly one processor: the AMD Ryzen 5 7640HS with Radeon 760M graphics. Two M.2 2280 PCIe 4.0 positions and up to 96 GB of DDR5 in a chassis this small are the reasons it keeps appearing in homelab shortlists, which is the same logic behind our complete homelab starter guide: topology first, CPU badge second.

That framing matters because the UM760 Slim is not a desktop-performance story. Six Zen 4 cores are more than enough for a compact virtualisation host, a container stack or a Jellyfin library, and independent testing puts whole-system idle draw between roughly 8 W and 16 W depending on configuration. What decides whether it fits a rack shelf is what it does not have: a second Ethernet port, a SATA bay, or — on the stock card — a Wi-Fi module that behaves under Linux.

This review is an audit, not a benchmark dump. The evidence covers Minisforum's specifications, AMD's platform documentation, and independent exact-machine measurements where available. No verified UM760 Slim test establishes a reproducible number of simultaneous 4K transcodes, so stream counts should not be assumed.

Before the sections, one naming trap. There is no plain "UM760". There is a UM760 Slim, a UM760 Pro (an older, taller, I/O-richer sibling), and a UM760 Plus (a newer, OCuLink-equipped model). The Ryzen 7 8745H belongs to the UM870 Slim, a different machine in a near-identical chassis. If a listing puts an 8745H under a UM760 Slim name, the listing is wrong.

Minisforum UM760 Slim — Specifications

Minisforum UM760 Slim — Overview & First Impressions

The UM760 Slim launched in the first week of September 2024 and has stayed in the Minisforum catalogue since, which is unusual for a 6-core SKU in a market that refreshes every nine months. The reason is architecture rather than horsepower: Ryzen 5 7640HS is a Phoenix part with 20 native PCIe 4.0 lanes on the CPU, and Minisforum routes them to two M.2 2280 sockets instead of the single slot that most of its direct competitors offer.

That is the differentiator that decides homelab purchases. Two internal NVMe drives let you separate the operating system from VM or container storage, run a scratch or transcode volume, or mirror a datastore where the software stack supports it. The older UM773 Lite takes the opposite approach — one NVMe slot plus a 2.5-inch SATA bay — which is cheaper for bulk SSD capacity but a worse fit for an all-NVMe layout.

Official configurations have varied by region and channel: barebone, 16 GB/512 GB, 16 GB/1 TB, 32 GB/512 GB and 32 GB/1 TB have all appeared on Minisforum properties. The current US storefront surfaced a 16 GB/1 TB build and its page notes 4800 MT/s for that specific configuration, even though the platform supports DDR5-5600. Treat the shipped memory speed as SKU-specific and check the module layout on the unit you receive — some preconfigured batches have shipped with a single SO-DIMM occupied, which halves bandwidth to the Radeon 760M.

Specs & What's in the Box

The retail package includes the mini PC, the 120 W (19 V / 6.32 A) power adapter, an HDMI cable, a VESA/wall-mounting bracket and the usual documentation. Minisforum lists "Wall Mounted Installation" among the contents, and independent testing confirms the unit works with a standard VESA plate.

Port layout, from the rear: DC input, one 2.5GbE RJ45, HDMI 2.1, DisplayPort 1.4, the USB4 Type-C, two USB 3.2 Gen 2 Type-A, two USB 2.0 Type-A and a 3.5 mm audio jack. The front carries a power button, a headphone jack and additional Type-A ports. For a three-display desk setup that is generous; for a 2U shelf it is more cabling than a headless host needs.

The three video outputs are genuinely independent. Independent testing confirmed simultaneous three-display operation, with output ceilings of up to 4K/120 Hz over HDMI, 4K/144 Hz over DisplayPort, and higher-bandwidth modes over USB4 depending on monitor and cabling. Those are signalling limits, not rendering promises — the Radeon 760M will not drive a modern game at 4K/120, and the distinction matters for anyone reading "4K/120" as a performance claim.

On the firmware side, Minisforum's support index reaches BIOS V1.09. Specific fan, sleep or wireless fixes should not be attributed to that version without confirmation. Virtualisation extensions are present and enabled by default on this platform family, and power-loss auto-restart and scheduled power-on are typically exposed in Minisforum's BIOS menus.

Build Quality & Durability

The chassis is a metal-topped enclosure with a plastic underside, held together with standard screws and accessible from the bottom panel. The secondary M.2 slot, the SO-DIMMs and the Wi-Fi card all sit under that cover; the CPU cooler sits over the primary drive position, so the first slot requires more disassembly than the second.

Cooling is where Minisforum made a deliberate design choice for a 24/7 box: the RAM and SSD get their own active cooling path, separate from the APU heatsink, and the CPU interface uses a phase-change thermal material rather than conventional paste. Minisforum markets "25% lower memory/SSD temperatures" and a "<35 dB performance mode" — both are vendor claims, not independently reproduced figures, and should be read as directional.

What independent testing does support is that the machine survives sustained torture loads. Office workloads sit around 35–50 °C; maximum-load testing reached roughly 85 °C, and a separate sustained FPU run held near 89 °C while continuing to operate. That is hot, and it is the expected consequence of a 35–54 W APU in a case this size — but the evidence describes a machine that runs hot under stress, not one with uncontrolled thermal failure. The available evidence does not establish chronic throttling in ordinary homelab workloads.

Two negatives worth stating plainly. First, fan control is limited: independent reviewers could neither read nor set fan speed through common software, and found no useful user-defined fan curve in BIOS. For a host that lives in a closet that is survivable; for a living-room shelf it removes your ability to trade acoustics against temperature. Second, no widespread coil-whine or sleep/wake defect was established for this model — one tested power supply had no audible whine, and Linux standby worked — so treat isolated reports as unit-specific rather than a model trait.

Performance — Proxmox, Media Serving and Idle Watts

CPU. The Ryzen 5 7640HS is a 6-core/12-thread Zen 4 part with 16 MB of L3 and a 35–54 W configurable envelope. Independent heavy-load testing measured approximately 82.6 W at the wall in a Cinebench run and about 90 W under maximum-stress conditions. That is whole-system draw, and it is roughly three times what the platform consumes at idle — the number that actually matters for a machine running 365 days a year.

Idle power. Measured figures cluster into a band rather than a single value: under 9 W at the wall on a Windows desktop in one test, 15.7 W in another configuration, and a community wattmeter test reporting about 12 W on the supplied 120 W supply versus about 8 W on a 65 W USB-PD source. Different PSUs, different storage, different NIC and wireless states — the spread is methodological, not contradictory. For planning, assume single-digit to low-teens watts idle and a 10 W delta is worth roughly 87.6 kWh per year, so the difference between a lean configuration and a loaded one is a real utility line item.

Noise. Heise measured about 30 dB(A) in office workloads and 42 dB(A) at maximum load. Chimolog, using a calibrated meter at 50 cm against a 31.1 dB background, measured 32.3 dB idle and 36.9 dB during Cinebench. The two datasets use different methods and should not be compared numerically; the shared conclusion is that the machine is close to inaudible at idle and clearly audible when all six cores are pinned.

Media and transcoding. The Radeon 760M carries hardware H.264, H.265/HEVC and AV1 encode, plus H.264, H.265/HEVC, VP9 and AV1 decode. On paper that is a complete modern codec set. In practice the software stack decides the outcome: Jellyfin documents AMD hardware acceleration on Linux through VA-API and recommends dual-channel memory because the iGPU shares system bandwidth, while Plex's hardware-transcoding documentation remains centred on Intel Quick Sync and NVIDIA, with AMD support less straightforward. For a Plex-first deployment, our Plex minimum requirements guide explains why that ecosystem gap can outweigh a CPU benchmark advantage. A fixed number of concurrent 4K transcodes should not be assumed for this model.

Proxmox and virtualisation. Proxmox runs on the UM760 Slim: an exact-model community report ran a Windows 11 VM on the machine. Basic virtualisation is not the constraint — device assignment is. Exposing the Phoenix iGPU cleanly to a guest required additional work rather than a checkbox workflow, which is consistent with the broader pattern we document in our Proxmox mini PC ranking. For a Jellyfin container, sharing the render device with the host or an LXC is usually the lower-friction path than full passthrough. That is why our best practices guide recommends sharing the render device with the host or an LXC.

Linux. The platform itself is fine, the wireless module is not. An Ubuntu 24.04-derived test installation had no working driver for the stock MediaTek MT7902 Wi-Fi/Bluetooth card, while wired RTL8125 networking worked as expected; a 2026 owner running SteamOS/Bazzite reported the same absence of Wi-Fi and Bluetooth. The remedy the community converges on is a card swap — an Intel AX210 or a compatible MediaTek MT7922 — which restores wireless. If the machine will live on Ethernet, this is a non-issue. If it will not, budget for the swap or choose a model with a different wireless module.

Power source nuance. USB4 accepts 65–100 W Power Delivery, but a first-hand wattmeter test found markedly lower stress-test wall power on a 65 W source than on the supplied 120 W brick. A single-cable setup is attractive for a low-load 24/7 server; it should not be presented as performance-equivalent to the factory adapter for sustained CPU work.

UM760 Slim vs the Alternatives — Head-to-Head

The honest competitive picture is not about CPU tiers. It is that the UM760 Slim's two limitations — one Ethernet port and no native OCuLink — are exactly what other models in the same class fix.

UM870 Slim — the direct step-up. Same Slim chassis, same 96 GB ceiling, same two NVMe slots, but an 8-core Ryzen 7 8745H and Radeon 780M. It does not change the single-NIC or OCuLink situation at all. This is the model most often confused with the UM760 Slim, because combined regional pages present both in one template. If your workload is CPU-bound and storage topology is already sufficient, this is the cleaner upgrade path within the family.

UM760 Pro — more I/O, less memory. The same 7640HS/760M in a slightly taller 130 × 126 × 52.3 mm chassis, with two USB4 ports and four USB 3.2 Gen 2 Type-A against the Slim's one and two, plus dual HDMI 2.1. The trade is a 64 GB official memory ceiling instead of 96 GB, and the model is now legacy rather than a headline product. Buy it for port count, not for headroom.

UM760 Plus — native OCuLink. The same processor with an OCuLink port built in, which is the difference between attaching an external GPU and consuming one of your two M.2 slots with an adapter. For a 2026 buyer whose roadmap includes a PCIe device, this is the model to look at rather than the Slim.

UM890 Pro and GMKtec K8 Plus — the network fix. Both offer dual 2.5GbE and native OCuLink alongside an 8-core CPU and Radeon 780M. For a pfSense/OPNsense host or a segmented lab, that pair of ports is worth more than any CPU bump: a second physical interface removes the VLAN-on-a-stick dependency and the recovery complexity that comes with it. Note that GMKtec's global documentation quotes up to 128 GB while some regional pages have cited 96 GB — verify the SKU you buy.

ACEMAGIC AM18 — the value play with a caveat. Current official material includes a 7640HS/Radeon 760M configuration with dual 2.5GbE, OCuLink, two M.2 2280 positions and a 96 GB ceiling — the same CPU class with a materially stronger platform. The catch is configuration hygiene: the preconfigured example pairs a single 16 GB DDR5-5600 module with a PCIe 3.0 SSD despite supporting faster storage, so inspect the exact build. Older Amazon results for the AM18 describe a 7840HS version and should not be inherited as reviews of the current SKU.

ASUS NUC 14 Pro / Pro+ — the Intel counter-argument. Core Ultra configurations support up to 96 GB DDR5-5600, dual Thunderbolt 4, Intel i226 2.5GbE and two M.2 formats, with ASUS explicitly specifying 24/7 sustained operation, a three-year warranty and toolless access. For a Plex-first deployment, Intel Quick Sync's software ecosystem is the reason to pay the premium; for a Proxmox application host, the UM760 Slim stays competitive on memory and dual full-size NVMe capacity. Full model-by-model context lives in our MINISFORUM brand guide, and if the workload is storage-first, the NAS mini PC ranking covers bay-count trade-offs the Slim does not compete on.

Recommended Upgrades

Memory — the first purchase, not the last. Radeon 760M shares system memory, and Jellyfin's own AMD guidance recommends dual-channel memory for exactly this reason. A single occupied SO-DIMM halves the bandwidth available to the iGPU. Two matched modules in DDR5-5600 is the correct baseline, and all three kits below sit inside Minisforum's official speed limit.

• 32 GB (2×16 GB) DDR5-5600 — the balanced choice for a lighter Proxmox host, a Docker stack or a media server. Crucial CT2K16G56C46S5.
• 64 GB (2×32 GB) DDR5-5600 — the natural target for several VMs plus containers, ZFS caching, or development environments. Crucial CT2K32G56C46S5.
• 96 GB (2×48 GB) DDR5-5600 — matches the platform maximum exactly, at the maximum supported speed. Crucial CT2K48G56C46S5. Worth it only when VM density justifies it; memory capacity does not remove the 6-core scheduling ceiling.

Storage — use the second slot deliberately. The sensible layout in a two-slot machine is host/VM separation on the first drive and a dedicated VM datastore, scratch or transcode volume on the second. Mini PC thermals mean you should not assume desktop-class sustained SSD throughput without checking the installed thermal pad contact.

• WD_BLACK SN850X 2TB — a PCIe 4.0 drive with DRAM, a reasonable premium choice for a VM datastore.
• Samsung 990 EVO Plus 2TB — a PCIe 4.0 x4-compatible general-purpose drive. It negotiates PCIe 4.0 here; PCIe 5.0 support is irrelevant in this chassis.

Neither drive is mandatory. Capacity, endurance and thermals decide a server build, not peak sequential numbers.

Wireless — only if Linux is the plan. If the host runs Linux and cannot sit on Ethernet, replace the MT7902 with an Intel AX210 or a compatible MediaTek MT7922. This is the single most common modification reported against this machine.

Power. A capable 100 W USB-PD supply can run the machine over USB4 Type-C and is attractive for a low-load always-on server. For sustained CPU work, the supplied 120 W adapter remains the reference.

OCuLink — the trade you have to accept. An M.2-to-OCuLink adapter works, but it consumes one of the two NVMe slots. If PCIe expansion is on the roadmap, the UM760 Plus or GMKtec K8 Plus provide it natively and leave both drive positions free.

Frequently Asked Questions

Conclusion & Final Verdict

The Minisforum UM760 Slim is a storage-and-memory platform that happens to be small, not a performance machine that happens to be small. Two M.2 2280 PCIe 4.0 positions and a 96 GB DDR5 ceiling in a 0.83-litre chassis, drawing single-digit to low-teens watts at idle, is a genuinely useful combination for a compact always-on host — and the independent thermal data supports sustained operation at 85–89 °C under torture loads without evidence of chronic throttling in real workloads.

The two constraints are structural and cannot be upgraded away. One 2.5GbE port rules out a conventional WAN/LAN firewall topology without VLANs or an external adapter. The absence of native OCuLink means PCIe expansion costs you an NVMe slot. Add a stock Wi-Fi module that does not work under Linux and limited fan control in BIOS, and the machine's fit becomes narrow and clear: a wired, single-network, storage-and-virtualisation host that runs cool enough and cheap enough to leave on.

Within its own family, buy the UM870 Slim if you want more CPU and GPU in the same chassis, the UM760 Plus if you want OCuLink without sacrificing a drive slot, and the UM890 Pro if you need two Ethernet ports and the expansion to go with them. Outside the family, the GMKtec K8 Plus and ACEMAGIC AM18 both pair the same or better silicon with dual NICs and OCuLink, and the ASUS NUC 14 Pro line buys Intel Quick Sync and a documented business lifecycle at a premium. The broader model-by-model context sits in our MINISFORUM brand guide; if the purchase is driven by virtualisation, start from the Proxmox host ranking, and if Linux is the target operating system, the Ubuntu mini PC guide covers the driver and firmware checks worth doing before you buy.

For the specific job the UM760 Slim is good at — a quiet, low-draw host with real storage headroom — it earns its place. For the jobs it is not built for, the honest answer is that a neighbouring model does them better.
