ASUS ROG Strix Z790-E Gaming WiFi motherboard: features and specs

The ASUS ROG Strix Z790-E Gaming WiFi is an ATX motherboard for Intel processors that use the LGA 1700 socket. It is the central circuit board of a custom-built PC, linking the processor, memory, storage, graphics card and ports. This page explains what the main specifications mean for someone planning a build.

Socket and chipset

LGA 1700 is the processor socket, and Z790 is the Intel chipset that goes with it. Z790 boards are typically the enthusiast tier, allowing processor overclocking on compatible unlocked chips. Socket support depends on the processor generation and the board's BIOS version, so check ASUS's CPU support list for the exact processor you plan to use.

Power delivery: 18+1 DrMOS

The board lists an 18+1 DrMOS power design. DrMOS integrates the switching components that feed the processor into compact power stages. Higher stage counts are generally intended to deliver steadier power to high-end processors under heavy load. The practical result depends on cooling and the processor, so treat the figure as a design indicator.

DDR5 memory

This board uses DDR5 RAM. DDR5 modules are physically different from DDR4 and are not interchangeable, so a build needs DDR5 sticks. Check the memory support list for supported speeds and capacities before buying kits.

PCIe 5.0 and five M.2 slots

PCIe 5.0 doubles the bandwidth per lane over PCIe 4.0. It matters most for the main graphics card slot and for the newest NVMe SSDs. ASUS lists five M.2 slots, which means several fast SSDs can sit directly on the board without cables. Sharing of bandwidth between slots and SATA ports varies by board, so consult the manual for which combinations can run at once.

Connectivity: WiFi 6E and USB 3.2 Gen 2x2

Built-in WiFi 6E adds access to the 6 GHz band where your router supports it, and the board includes wireless without a separate card. There is a USB 3.2 Gen 2x2 Type-C port, which the listing describes as supporting USB Power Delivery 3.0 up to 30W. Gen 2x2 is rated at up to 20 Gbps for compatible devices.

Lighting

Aura Sync RGB lets you coordinate lighting with other compatible ASUS parts through ASUS software.

Size and who it suits

The ATX form factor is the standard full-size layout and needs a compatible case. The board suits builders creating a high-performance gaming or content-creation PC who want plenty of storage slots and current-generation connections. It is more than a basic office computer needs.

What to check before you buy

• Processor: confirm your chip is compatible, and whether the board needs a BIOS update to run it.
• Memory: buy DDR5 only; DDR4 will not fit.
• Case and power supply: check ATX case support and the connectors your power supply provides.
• Storage plans: read the manual for which M.2 slots and SATA ports can be used together.
• Cooling: confirm your processor cooler fits the socket and that the case has clearance.
• Operating system: you will need to install one, as a bare board does not include it.

The short version

• An ATX motherboard for Intel LGA 1700 processors with the Z790 chipset.
• 18+1 DrMOS power design and DDR5 memory.
• PCIe 5.0, with five M.2 slots.
• WiFi 6E and a USB 3.2 Gen 2x2 Type-C port with PD 3.0 up to 30W.
• Aura Sync RGB lighting.
