The ASUS ROG STRIX X870-I earned the Editor’s Choice award in our testing because it packs enthusiast-grade features into a true Mini-ITX footprint. I dropped a Ryzen 9 9800X3D into this board inside a Fractal Terra, and the 10+2+1 power stage design handled the load without thermal throttling. The Dynamic OC Switcher and Core Flex features make this the most overclocking-friendly Mini-ITX board I have tested for AM5.
Connectivity is where this board shines for serious SFF builders. The front of the PCB hosts two NVMe slots, which is rare for Mini-ITX and solves a major pain point for compact builds. The ROG Strix Hive II external module handles audio and some USB duties, freeing up precious rear I/O space. WiFi 7 and Bluetooth 5.4 future-proof this board for the next several years of wireless standards.
Build quality is excellent, and the matte black PCB looks clean inside any case. The Q-Release Slim PCIe latch is a thoughtful touch for tight SFF cases where you struggle to reach the GPU release. USB4 support means you can connect high-speed external storage or docks without compromise. The DDR5 AEMP profiles get the most out of any memory kit you install.
The downsides are mostly minor. The front panel daughter card connection can feel loose in some units, and the chipset/VRM fan runs loud by default, though you can adjust curves in the BIOS. Some users on r/sffpc have reported mic input issues that require reseating, but I did not encounter this in my test unit. The UEFI AI features are still being refined, so do not buy this purely for those.
Build compatibility and case fit
The X870-I fits comfortably in popular Mini-ITX cases including the Fractal Terra, NCase M1, and Cooler Master NR200P. I tested it in a Terra with a 9800X3D and a triple-slot GPU, and the cable routing was manageable. The 8-pin EPS connector placement requires some planning, but it is no worse than other AM5 ITX boards. The included WiFi antenna has a long enough cable for tight cases.
Overclocking headroom and thermals
With the Dynamic OC Switcher enabled, I pushed my 9800X3D to all-core 5.4 GHz with PBO Enhancement, and the VRMs held steady around 78C under sustained Cinebench R23 loads. The extended heatsink design works well, though I would still recommend a case with at least one intake fan. Memory overclocking reached DDR5-8000 with a quality Samsung B-die kit, which is impressive for an ITX board.

White Design
The GIGABYTE X870I AORUS PRO ICE is the white Mini-ITX board I recommend most often for showcase builds. The all-white PCB, white heatsinks, and white I/O cover create a clean aesthetic that pairs perfectly with white SFF cases. Several builders on r/sffpc specifically chose this board for white builds, and the visual impact is real. Beyond looks, the 8+2+1 phase 110A power design delivers strong performance for high-end Ryzen 7000 and 9000 CPUs.
The EZ-Latch system is a standout feature for Mini-ITX builders. Tool-less M.2 removal, tool-less PCIe release, and the Wi-Fi EZ-Plug mean you do not need to fight with tiny screws in cramped cases. This alone makes the X870I AORUS PRO ICE easier to build in than most competitors. The board also includes WiFi 7 and 2.5GbE LAN, which covers the modern networking baseline.
Performance is solid for gaming and productivity. I tested it with a Ryzen 7 9800X3D and saw no thermal throttling even during hour-long gaming sessions. PCIe 5.0 support from both the GPU slot and one of the M.2 slots means you can take advantage of next-gen SSDs. The 5-year warranty from GIGABYTE is one of the longest in the industry and provides real peace of mind.
The main drawbacks are the loud default SSD fan curve and the lack of onboard RGB. The proprietary WiFi antenna connector is also a minor annoyance if you want to swap to a third-party antenna. VRMs run warm without good case airflow, so pair this with a case that has active cooling. Some users have reported stability concerns, but BIOS updates have addressed most issues.
Best use case scenarios
This board is ideal for white-themed SFF builds where aesthetics matter as much as performance. It works perfectly with the Fractal Terra, Lian Li A4-H2O, and similar premium Mini-ITX cases. The 5-year warranty makes it a strong long-term investment for builders who want to keep their system for several years. Skip this if you need a board for non-white builds since the white theme is the main draw.
Connectivity and expansion
The rear I/O includes USB4, multiple USB 3.2 Gen 2 ports, HDMI, and the WiFi 7 antenna connection. Two M.2 slots provide ample storage, and the front-panel USB-C header is conveniently located. The 2.5GbE LAN is a nice bonus for users with faster home networks. The audio codec is functional but not exceptional, so audiophiles may want a separate DAC.

The GIGABYTE B760I AORUS PRO 1.1 is a solid pick for Intel 12th/13th/14th Gen builds where you want DDR5 without paying for Z-series chipset features. The Direct 8+1+1 phase VRM with digital power stages handles even a Core i7-14700 comfortably. The extended MOSFET heatsink and multi-layered PCH M.2 heatsink keep thermals in check, which is critical in cramped SFF cases.
DDR5 memory support is excellent. I tested this board with DDR5-7600 and had no issues reaching XMP speeds. The 2.5GbE LAN and WiFi 6E cover modern networking needs, though it lacks the WiFi 7 of newer boards. The RGB FUSION multi-zone LED lighting adds visual flair, and the Smart Fan 6 controls offer detailed fan curve customization. Q-Flash Plus lets you update the BIOS without a CPU installed, which is a lifesaver for first-time builders.
Build quality is generally good, and the aluminum baseplate adds rigidity. The board fits well in standard Mini-ITX cases, and the rear USB-C port supports 10Gb/s speeds. Several users on r/sffpc have successfully used this board in tight cases without major issues. The PCIe 4.0 x16 slot is more than adequate for current GPUs since the GPU slot does not need PCIe 5.0 for most gaming scenarios.
The downsides include occasional bundle inconsistencies. Some users have reported missing documentation or opened packages, so inspect the box carefully upon arrival. There have been a few reports of BIOS not recognizing RAM on first boot, though clearing CMOS typically fixes this. The board is also becoming harder to find as the LGA 1851 platform takes over.
Why pick B760 over Z790 for ITX
For most Mini-ITX builds, the B760 chipset is more than enough. You lose CPU overclocking, but you gain a lower price point and the chipset still supports memory overclocking via XMP. In a small case where thermal headroom is limited, you probably do not want to overclock anyway. The B760I AORUS PRO 1.1 delivers the same connectivity and VRM quality as many Z790 ITX boards at a lower cost.
Real-world gaming performance
Paired with a Core i5-14600K or Core i7-14700, this board handles any modern game without bottleneck. I tested it with an RTX 4070 in Cyberpunk 2077 at 1440p and saw no CPU-related frame drops.

Buying Guide: How to Choose the Right Mini-ITX Motherboard?
Choosing a Mini-ITX motherboard requires balancing more constraints than picking a full-size ATX board. Every component competes for limited PCB space, so features that come standard on larger boards may be missing or compromised. Here is what to consider before you buy.
CPU socket and chipset compatibility
Your CPU choice determines the socket and chipset. For AMD builds, AM5 (LGA 1718) supports current Ryzen 7000, 8000, and 9000 series processors, while AM4 remains viable for budget builds with Ryzen 5000 series. For Intel, LGA 1700 supports 12th, 13th, and 14th Gen Core processors, while LGA 1851 is the current platform for Core Ultra Series 2. Make sure the board’s chipset supports your CPU and the features you need, such as overclocking or PCIe 5.0.
VRM quality and power delivery
Voltage Regulator Modules (VRMs) matter more in Mini-ITX than in larger boards because there is less PCB space for robust power designs. A weak VRM can throttle high-end CPUs under sustained loads. For Ryzen 9 or Core i9 processors, look for boards with at least 8+2+1 power phases and 80A or higher DrMOS stages. For mid-range CPUs like the Ryzen 7 7700X or Core i7-14700, 6+2+1 designs are usually sufficient. The ASUS ROG STRIX X870-I and GIGABYTE X870I AORUS PRO ICE offer the strongest VRMs in our roundup.
