The Verdict
This isn’t your typical motherboard. The MINISFORUM BD790i X3D packs an AMD Ryzen 9 7945HX3D — a 16-core, 32-thread laptop chip with 128MB of 3D V-Cache — directly onto a Mini-ITX board. If you’re building a small-form-factor (SFF) rig for gaming or heavy productivity, this is a shortcut to serious performance without the bulk of a full ATX tower.
What’s in the box
You get the motherboard with the CPU already installed and soldered, a pre-mounted 120mm AIO liquid cooler, two SATA cables, a Wi-Fi antenna set, and the I/O shield. That’s a complete cooling solution out of the box — no separate CPU or cooler purchase needed. The board measures a true Mini-ITX 17x17cm, so it fits any SFF case that supports that standard.
Performance and build quality
The 7945HX3D is a beast. With 16 cores based on Zen 4 and that massive L3 cache, it trades blows with desktop chips like the Ryzen 9 7950X in multi-threaded tasks and actually beats most of them in games that love cache — think simulation titles, MMOs, and esports shooters. In Cinebench R23, buyers report multi-core scores around 34,000, which is remarkable for a board this size.
The AIO cooler handles the thermals well — the chip runs at about 85°C under full load, which is normal for this mobile silicon. Idle temps sit around 40°C. The board has two M.2 PCIe 5.0 slots for storage, so you’re not bottlenecked on SSD speeds. Dual 2.5GbE ports are a thoughtful touch for NAS users or anyone running a home server.
What buyers consistently praise
The performance-per-liter is the headline. One verified buyer put it plainly: “This thing shreds my old desktop. I downsized to a 10-liter case and gained 30% more FPS.” Another noted the convenience: “No CPU installation, no cooler compatibility research — everything was ready to drop in my case.”
Where it falls short
The proprietary cooling mount is the biggest risk. If that AIO pump dies, you can’t just grab a standard LGA1700 or AM5 cooler — you’re hunting for a specific adapter or contacting MINISFORUM for a replacement. That’s a real longevity concern. Also, since the CPU is soldered, there’s zero upgrade path. You’re committing to this chip for the life of the build. And the SO-DIMM slots mean laptop RAM, which costs about 15-20% more than equivalent desktop DIMMs.
Who should buy this
If you’re a gamer who wants a tiny living-room rig or a portable workstation, this is ideal. It’s also great for homelab enthusiasts who want a powerful, low-power server — the 7945HX3D sips around 45W at idle. It’s not for tinkerers who like swapping components or overclockers chasing extreme frequencies.
FAQ
Can I use a standard CPU cooler with this board? No. The mounting holes are proprietary to the included AIO. You’d need an adapter from MINISFORUM or a third-party bracket.
Does it support ECC memory? No. It’s standard DDR5 SO-DIMM only, up to 96GB.
Is the Wi-Fi module replaceable? Yes, it’s an M.2 2230 card. You can swap it for a better one if needed.
The Verdict
Buy it if you want desktop-class performance in a tiny footprint and don’t mind a sealed CPU. Skip it if you value upgradeability or want to choose your own cooler.
The MINISFORUM BD790i X3D is a niche product done well. It earns a 4.2/5 for delivering exceptional compute density, though the proprietary cooling and non-upgradeable chip cap its long-term appeal. At its price point, it’s a compelling shortcut to a powerful SFF build — just know what you’re signing up for.
