Written analysis

ASUS Prime Z790-A WiFi 6E at a glance

The ASUS Prime Z790-A WiFi 6E uses the ATX form factor, LGA 1700 socket, and Z790-A 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 7200 MT/s. 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 53.0, placing the power delivery in the mid-range class. The board lists 16 CPU power phases, 60 A power stages in a 16+1+1 layout. CPU power input is listed as 2. It is a sensible match for mainstream processors, with conservative tuning on higher-power chips.

Expansion and storage

The expansion and storage score is 103.0: exceptionally well equipped . The platform supports PCIe 5.0. Physical expansion includes 2 ×16 slots, 1 ×4, and 2 ×1.

On-board storage consists of 4 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 67.0, rated adequate . Wireless networking is Wi-Fi 6E ; wired networking is 1 x Intel® 2.5Gb Ethernet 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 82.0. This is a high-end onboard implementation using Realtek S1220A, suitable for good headsets, powered speakers, and everyday content work. The rear panel has 3 analogue jacks.

Buying verdict

Overall quality is 79.40, 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 34.3. The nearby-board comparison below may reveal a better-equipped option at a similar price.
