Written analysis

GIGABYTE Z790I AORUS Ultra at a glance

The GIGABYTE Z790I AORUS Ultra uses the Mini-ITX form factor, LGA 1700 socket, and Z790I chipset. This is a high-end platform with the feature headroom expected in an enthusiast gaming or productivity build.

Memory support is DDR5 across 2 DIMM slots, with up to 128 GB and rated overclocked speeds up to 8000 MT/s. ECC modules are accepted, subject to CPU support. XMP / EXPO memory-profile support is recorded for easier tuning.

Best fit: a performance gaming and productivity PC that needs a balanced board without workstation-class excess.

Power delivery

The calculated VRM score is 48.0, placing the power delivery in the mid-range class. The board lists 10 CPU power phases, 105 A power stages in a 10+1+2 layout. CPU power input is listed as 1. It is a sensible match for mainstream processors, with conservative tuning on higher-power chips.

Expansion and storage

The expansion and storage score is 51.0: focused on the essentials. The platform supports PCIe 5.0. Physical expansion includes 1 ×16 slot.

On-board storage consists of 2 M.2 slots and 2 SATA ports. Supported M.2 lengths are listed as 2280, 2260. The two-slot layout covers a typical OS-and-games or OS-and-project-drive setup.

Connectivity and rear I/O

The connectivity score is 65.0, rated adequate . Wireless networking is Wi-Fi 6E ; wired networking is Intel® 2.5GbE LAN chip (2.5 Gbps/1 Gbps/100 Mbps) at up to 2500 Mbps. Bluetooth 5.3 is included. The recorded USB provision is 8 rear connections and 7 front-panel connections. The specification sheet below separates every USB speed and connector type.

Display connectivity includes HDMI 2.1, DisplayPort 1.4. These motherboard outputs require a processor with integrated graphics.

Audio

The audio score is 85.0. This is a high-end onboard implementation using Realtek® ALC4080 CODEC, suitable for good headsets, powered speakers, and everyday content work. The rear panel has 2 analogue jacks.

Buying verdict

Overall quality is 68.20, a strong performance-class result. This is the practical sweet spot for a powerful gaming or productivity PC without paying for every flagship extra.

At the recorded Amazon price, the quality-to-price score is 44.2. The nearby-board comparison below may reveal a better-equipped option at a similar price.
