The Verdict
The MINISFORUM UM890 Pro is the kind of machine that makes you question why you ever bought a tower PC. It’s smaller than a paperback novel, yet it packs an AMD Ryzen 9 8945HS — an 8-core, 16-thread CPU that’s genuinely fast enough to replace a full desktop for most office work, light video editing, and even some gaming.
What’s in the box
You get the UM890 Pro unit itself, a 120W power adapter, an HDMI cable, a VESA mounting plate with screws, and a quick-start guide. As shown in the product image, the chassis is a clean aluminum-and-plastic hybrid with a subtle textured top — it looks professional on a desk and disappears behind a monitor if you use the included VESA mount. Port selection is generous: two USB4 ports, two 2.5G Ethernet jacks, dual HDMI 2.1, one DisplayPort, and four USB-A 3.2 ports spread front and back.
Real-world performance
The 8945HS is the star here. In Cinebench R23, the UM890 Pro scores around 17,500 multi-core — that’s within striking distance of a Ryzen 7 7700 desktop chip. For everyday tasks like spreadsheets, web browsing, and coding, you’ll never notice it’s not a full-size PC. The integrated Radeon 780M graphics are surprisingly capable too; you can play esports titles like CS2 or Valorant at 1080p with decent settings, and it handles 4K video playback without a hiccup.
What buyers consistently praise
The networking setup gets a lot of love. As one buyer put it: “Dual 2.5G Ethernet is a game-changer for my homelab — I run Proxmox with multiple VMs and the bandwidth headroom is fantastic.” Another reviewer noted, “Boots to Windows 11 in about 15 seconds and stays quiet during normal office work.” The USB4 ports also impressed: “Transferring large video files to an external NVMe enclosure hit nearly 3GB/s — faster than my old desktop’s internal SATA drive.”
Where it falls short
The fan noise is the most common complaint. At idle, it’s essentially silent. Under sustained load — think a long render or a gaming session — the fan spins up to a noticeable whine that’s audible across a quiet room. It’s not deal-breaking, but if you’re noise-sensitive, factor that in.
The bigger limitation is upgradability. The 32GB RAM is soldered to the board, so you’re locked into that config. Storage is fine — there are two M.2 2280 PCIe 4.0 slots — but memory is non-negotiable. Also, there’s no OCuLink port, meaning external GPU expansion runs over USB4, which caps performance at roughly 60-70% of what you’d get from an internal card.
Who should buy this
- Remote workers or students who want a tiny, powerful machine that takes up almost no desk space
- Homelab enthusiasts who need dual Ethernet for routing, NAS, or virtualization projects
- Creative professionals doing light-to-moderate video editing who don’t want a bulky tower
- Travelers who need a portable workstation — it fits in a backpack and runs off USB-C power
Skip it if you need max GPU performance, plan to upgrade RAM later, or demand silent operation under full load.
FAQ
Q: Can I game on the UM890 Pro? A: Yes, but set expectations. Integrated Radeon 780M handles esports and older AAA titles at 1080p medium. Modern heavy hitters like Cyberpunk will run at 30-40fps on low settings. For serious gaming, you’d want an eGPU over USB4, but that adds cost.
Q: Does it come with Windows 11 or a barebones option? A: Most listings include Windows 11 Pro pre-installed, though barebones versions exist without RAM/SSD. Check the specific listing you’re buying from — the included 32GB RAM/1TB SSD config is the most popular.
Q: Is the fan always loud? A: No. At idle and light loads, it’s near-silent. The noise kicks in under sustained CPU/GPU load. You can adjust fan curves in the BIOS, which helps slightly, but it won’t eliminate the sound during heavy workloads.
The Verdict
Buy it if you want desktop-class CPU performance in a chassis smaller than a hardcover book, need dual 2.5G Ethernet, and don’t plan on upgrading RAM.
Skip it if you’re noise-sensitive, want future memory expansion, or need strong GPU performance without an eGPU setup.
At 4.1 stars from 204 ratings, the UM890 Pro earns its score — it’s a genuinely powerful, well-connected mini PC with real tradeoffs around thermals and upgradability. For the right buyer, it’s an exceptional value.
