Who it fits
Good fit for
This motherboard suits builders who need a compact system without sacrificing modern connectivity. The Mini-ITX size fits small cases, while the Z890 chipset and LGA 1851 socket ensure compatibility with the latest Intel Core Ultra CPUs. You will appreciate the PCIe 5.0 support for future-proofing your GPU or SSDs. The inclusion of Thunderbolt 4 and Wi-Fi 7 makes it ideal for users who require high-speed data transfer and wireless performance in a small footprint. The robust power design also benefits those planning to run high-end processors in tight spaces.
Who should skip it
You should look at another option if you need extensive expansion slots. The Mini-ITX form factor limits you to a single PCIe slot for graphics cards. If you require multiple GPUs or many add-in cards, this board is not suitable. Additionally, it only has two DDR5 DIMM slots, which may be insufficient for users needing high memory capacity. The two M.2 slots are also limited compared to larger ATX boards. If you prioritize maximum storage and expansion options over compact size, a larger motherboard would serve you better.
Verdict: The GIGABYTE Z890I AORUS Ultra is a capable Mini-ITX board for Intel Core Ultra Series 2 systems. It balances compact size with modern features like PCIe 5.0 and Wi-Fi 7.
Key specs explained
Form Factor: Mini-ITX
This motherboard measures 6.7 by 6.7 inches, making it significantly smaller than standard ATX boards. You will need a compact case to house it, which limits expansion slots but saves desk space. This format suits builders who prioritize a small footprint over having multiple graphics cards or numerous internal drive bays available for future upgrades.
CPU Socket: LGA 1851
The LGA 1851 socket is designed specifically for Intel Core Ultra Processors (Series 2). You must pair this board with compatible CPUs from this specific generation to ensure basic functionality. Older LGA 1700 processors will not fit, so this specification locks you into the latest Intel architecture for your build project.
Memory Type: DDR5
This board supports DDR5 RAM, which offers higher bandwidth and efficiency compared to older DDR4 standards. You will need to purchase DDR5 modules, as DDR4 sticks are physically incompatible with these slots. This choice ensures faster data transfer rates for your applications, though it requires investing in newer, typically more expensive memory kits.
PCIe Version: PCIe 5.0
The board features PCIe 5.0 lanes, which double the data transfer speed of the previous generation. This is ideal for future-proofing your high-end graphics card or ultra-fast NVMe storage drives. While current devices may not fully utilize this speed, having it ready ensures your system remains capable as newer peripherals demand more bandwidth over time.
Wi-Fi Standard: Wi-Fi 7
Integrated Wi-Fi 7 provides significantly higher throughput and lower latency than older Wi-Fi 6 or 6E standards. You benefit from more stable wireless connections for gaming and large file transfers, especially in congested network environments. This feature eliminates the need for a separate wireless card, saving a PCIe slot and simplifying your overall cable management.
Design and Hardware Layout Specs
The GIGABYTE Z890I AORUS Ultra comes in a black finish, according to the listing. The physical dimensions show a height of 2 inches, and the complete board weighs 2.8 pounds. Much of that weight comes from its thermal cooling hardware, which includes VRM Thermal Armor and an M.2 Thermal Guard. These integrated metal heatsinks sit directly over the voltage delivery circuits and storage drives. They help manage heat generation inside tight small-form-factor cases where system airflow is naturally restricted.
The layout centers on an 8+1+2 phase power design utilizing 105A Smart Power Stages to deliver stable power. Board space is tightly allocated, providing two DDR5 DIMM slots with support for XMP memory modules. For storage and graphics hardware, the PCB accommodates two M.2 slots alongside a single PCIe 5.0 expansion slot along the bottom edge.
According to the listing, internal connections feature a Front USB-C header and an onboard Sensor Panel Link. The Sensor Panel Link lets you connect an internal monitoring screen directly inside your chassis without routing display cords outside. The design also incorporates Thunderbolt 4, 2.5GbE wired network connectivity, and Wi-Fi 7 hardware, giving you fast data and networking paths without taking up physical slots.
Setup and Everyday Use
Setting up this Mini-ITX board requires careful planning due to its compact 6.7 by 6.7-inch footprint. You must select a case that accommodates the 2.8-pound board and its specific dimensions. The LGA 1851 socket means you need an Intel Core Ultra Processor (Series 2). Power delivery relies on an 8+1+2 phase design with 105A smart power stages. This configuration supports stable operation under load, though you must ensure your power supply connects correctly to the limited connectors available on a small board.
Memory installation involves two DDR5 DIMM slots. You should verify XMP memory module support for your chosen RAM sticks to achieve advertised speeds. Storage expansion offers two M.2 slots, both compatible with PCIe 5.0. This allows for high-speed data transfer if you install compatible NVMe drives. The board includes thermal protection via VRM Thermal Armor and M.2 Thermal Guard, which helps maintain performance during intensive tasks.
For daily connectivity, you get Wi-Fi 7 and 2.5GbE Ethernet. These standards provide robust wireless and wired networking for modern devices. Thunderbolt 4 support enables fast external storage and display connections. A front USB-C port adds convenience for peripheral access. The sensor panel link feature allows for additional monitoring if your case supports it. Overall, the setup process demands attention to space and component compatibility, but the resulting system offers high-end connectivity and processing power in a small package.
What To Check Before Buying
Before you buy, verify case compatibility. This Mini-ITX board measures 6.7 by 6.7 inches. You need a small form factor chassis that fits these dimensions. The LGA 1851 socket requires an Intel Core Ultra Processor (Series 2). Standard LGA 1700 CPUs will not fit. Check your RAM type. This board uses DDR5 memory. You must buy compatible DDR5 modules. Two DIMM slots are available. XMP support is listed. Ensure your chosen memory supports this profile. Consider storage needs. Two M.2 slots are provided. They support PCIe 5.0 speeds. You need compatible NVMe drives for these slots. Power delivery uses an 8+1+2 phase design. This handles high-end CPUs well. Verify your PSU has the required connectors. Wi-Fi 7 and Thunderbolt 4 are included. You do not need extra expansion cards for basic connectivity. This board suits compact builds focused on modern performance.
Check before you buy
- Verify your case fits the 6.7 by 6.7-inch Mini-ITX size.
- Ensure you have an Intel Core Ultra Series 2 CPU.
- Buy DDR5 memory modules compatible with XMP profiles.
- Confirm your power supply supports the board's power requirements.
- Check that your NVMe drives support PCIe 5.0 speeds.
