Written analysis

GIGABYTE Z790 AORUS Master X at a glance

The GIGABYTE Z790 AORUS Master X uses the E-ATX form factor, LGA 1700 socket, and Z790 chipset. This is a high-end platform with the feature headroom expected in an enthusiast gaming or productivity build.

Memory support is DDR5 across 4 DIMM slots, with up to 256 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 premium gaming or creator build that will use the stronger VRM, storage, and I/O rather than simply needing a compatible socket.

Power delivery

The calculated VRM score is 105.0, placing the power delivery in the ultra high-end class. The board lists 20 CPU power phases, 105 A power stages in a 20+2+1 layout. CPU power input is listed as 2. That is appropriate for sustained high-power CPUs and aggressive tuning when case airflow and VRM cooling are also adequate.

Expansion and storage

The expansion and storage score is 89.0: exceptionally well equipped . The platform supports PCIe 5.0. Physical expansion includes 3 ×16 slots.

On-board storage consists of 5 M.2 slots supporting x4/x2 and 4 SATA ports. Supported M.2 lengths are listed as 25110, 22110, 2280, 2260. That is enough NVMe capacity for a multi-drive gaming or creator setup without immediately relying on an add-in card.

Connectivity and rear I/O

The connectivity score is 108.0, rated premium . Wireless networking is Wi-Fi 6E ; wired networking is Marvell® AQtion AQC113C 10GbE LAN chip (10 Gbps/5 Gbps/2.5 Gbps/1 Gbps/100 Mbps) at up to 10000 Mbps. Bluetooth 5.3 is included. The recorded USB provision is 14 rear connections; a front-panel total is not recorded. The specification sheet below separates every USB speed and connector type.

Display connectivity includes DisplayPort 1.2. These motherboard outputs require a processor with integrated graphics.

Audio

The audio score is 98.0. This is an ultra-premium onboard implementation based on Realtek® ALC1220-VB CODEC, ESS ES9118 DAC chip, aimed at users who want strong analogue output without immediately adding a USB DAC. The rear panel has 2 analogue jacks. Optical S/PDIF is present for digital audio equipment.

Buying verdict

Overall quality is 98.40, a premium result. It makes sense when the build will use its stronger VRM and richer connectivity; otherwise a lower-tier board may deliver the same CPU performance for less.

At the recorded Amazon price, the quality-to-price score is 37.4. This is a feature-first premium purchase; compare nearby boards if several flagship extras would go unused.
