Product Showcase
The ASUS ROG Z790 STRIX Wifi II is an updated variant of the regular WIFI one, distinguished by its integration of the Wi-Fi 7 wireless network module and ASUS WiFi Q-Antenna directional antenna. This model stands out for its technical enhancements, including five M.2 slots and direct support for PCIe 5.0 x4, eliminating the need for additional expansion cards.
Visual aesthetics remain largely unchanged from its predecessor, with the VRM heatsink maintaining its design language. The most significant modification is the chipset sharing its heatsink with the M.2 slots, including a dedicated M.2_1 heatsink to support PCIe 5.0 x4. These subtle adjustments result in a more streamlined appearance while retaining the 18 (vCore) + 1 (GT) + 2 (AUX) phase VRM design backed by 110A Power Stages and one of the finest DIGI+ Power control and high-quality alloy chokes in the industry to ensure clean power delivery.
Additionally, the DDR5 memory module slot now supports overclocking up to DDR5-8000+.
Installation configurations offer versatility, with numerous fan sockets and provisions for water cooling. Notable features include various lighting, temperature measurement sockets, Q-Code, Q-LED indicators, and memory fan brackets. It's worth mentioning that VRM cancellation is no longer supported.
The motherboard accommodates three PCIe bus interface slots, with the first PCIe x16 slots supporting PCIe 5.0 for x16 / x0 or x8 / x8 configurations, this is a user-friendly PCIe Slot for easy graphics card removal with its Q-Release design. The other x16 slots offer PCIe 4.0 up to x4.
The back panel Io port offers 1 x USB 20Gbps port (1 x USB Type-C )
11 x USB 10Gbps ports (10 x Type-A + 1 x USB Type-C )
1 x DisplayPort
1 x HDMI port
1 x Wi-Fi module
1 x Intel 2.5Gb Ethernet port
5 x Gold-plated audio jacks
1 x Optical S/PDIF out port
1 x BIOS FlashBack button
1 x Clear CMOS button.
Storage configurations have evolved to NVMe, reducing SATA 6Gb/s ports from six to four, all directly provided by the chipset without third-party controllers. M.2 slots have undergone improvements, with ASUS eliminating the ROG Hyper M.2 expansion card option and offering a maximum of five groups. These M.2 slots incorporate the M.2 Q-Latch design, come with heatsinks, and include thermal pads, although the cooling base plate is provided only for the first three groups. Notably, M.2_1 allocates 16 PCIe 5.0 lanes to address potential high-temperature concerns.
