Written analysis

ASUS ROG Strix Z790-A at a glance

The ASUS ROG Strix Z790-A uses the 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 192 GB and rated overclocked speeds up to 8000 MT/s. 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 61.0, placing the power delivery in the upper mid-range class. The board lists 16 CPU power phases, 70 A power stages in a 16+1+2 layout. CPU power input is listed as 2. It suits performance processors at stock; sustained extreme overclocking is not its main purpose.

Expansion and storage

The expansion and storage score is 96.0: exceptionally well equipped . The platform supports PCIe 5.0. Physical expansion includes 2 ×16 slots, and 1 ×1.

On-board storage consists of 5 M.2 slots and 4 SATA ports. Supported M.2 lengths are listed as 22110, 2280, 2260, 2242. 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 89.0, rated premium . Wireless networking is Wi-Fi 7 ; wired networking is 1 x Intel® 2.5Gb Ethernet at up to 2500 Mbps. Bluetooth 5.4 is included. The recorded USB provision is 12 rear connections; a front-panel total is not recorded. 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 88.0. This is a high-end onboard implementation using ALC4080, suitable for good headsets, powered speakers, and everyday content work. The rear panel has 2 analogue jacks. Optical S/PDIF is present for digital audio equipment.

Buying verdict

Overall quality is 86.80, 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 32.1. This is a feature-first premium purchase; compare nearby boards if several flagship extras would go unused.
