The Asus Z790-AYW Wi-Fi W II is an ATX form factor motherboard measuring 305 mm wide and 244 mm tall, built around the Z790 chipset with a single LGA 1700 CPU socket and no integrated CPU or graphics. Wireless connectivity covers Wi-Fi 4, 5, and 6 (802.11ax) alongside Bluetooth 5.3, though aptX audio over Bluetooth is not supported. The board features an HDMI 2.1 output and includes RGB lighting, and it is designed to support overclocking without complex procedures. It does not offer dual BIOS or an easy CMOS reset function, and it carries no integrated graphics solution. A three-year warranty is included with the board.
This motherboard supports DDR5 memory across four slots in a dual-channel configuration, with a maximum capacity of 192 GB. The standard rated speed tops out at 5600 MHz, while overclocked profiles can push that figure up to 8000 MHz. ECC memory is not supported on this board.
The rear I/O panel provides a varied USB selection, including one USB 3.2 Gen 2 Type-A port, two USB 3.2 Gen 1 Type-A ports, one USB 3.2 Gen 2 Type-C port, and four USB 2.0 ports; there are no USB 3.2 Gen 1 Type-C, Gen 2x2, USB 4, Thunderbolt 3, or Thunderbolt 4 ports present. Video output is handled by a single HDMI port, while DisplayPort, DVI, and VGA connectors are absent. Wired networking is served by one RJ45 port, and there are no eSATA or PS/2 ports on this board.
Internal connectivity includes four USB 3.2 Gen 1 headers and four USB 2.0 headers for front-panel expansion, along with one USB-C 3.2 Gen 2 internal connector; there are no Gen 2, Gen 2x2 Type-A, or USB 3.0 expansion headers beyond those noted. Storage is handled by three M.2 sockets and four SATA 3 connectors, with no SATA 2, mSATA, or U.2 sockets present. The board also provides five fan headers and includes a TPM connector for platform security modules.
The board offers a total of five PCIe slots: one PCIe 5.0 x16 slot for the primary graphics card or high-bandwidth add-in cards, three PCIe 3.0 x16 slots for additional expansion, and one PCIe x1 slot for smaller cards. There are no PCIe 4.0 x16, PCIe 2.0 x16, PCIe x4, PCIe x8, or legacy PCI slots present.
The onboard audio supports a 7.1-channel configuration and is accessible through three analog audio connectors on the rear panel. There is no S/PDIF optical output on this board.
The board supports RAID 0, 1, 5, and 10 (1+0) configurations, covering the most commonly used modes for both performance and redundancy setups. RAID 0+1 is not supported.
