Design & Build Quality
ASUS has pulled out all the stops on the ASUS ROG Strix Z790-I Gaming WiFi. The board features an extensive heatsink array covering the VRM, chipset, and M.2 slots, with a premium aesthetic that includes brushed metal accents and subtle RGB integration. The PCB is a high-quality multi-layer design built for signal integrity at high frequencies, and the overall build quality is immediately apparent when you handle the board.
VRM & Power Delivery
With a 14+1 power stage configuration, this board handles demanding workloads confidently. The VRM can sustain full power delivery to multi-core processors without thermal throttling under normal conditions. While it may not be designed for extreme overclocking records, it provides excellent stability for real-world high-performance use.
Connectivity & I/O
WiFi 6E extends into the clean 6GHz band, reducing congestion and improving latency compared to standard WiFi 6. 5 Gigabit Ethernet provides excellent wired speeds for NAS and local network transfers. The rear panel features 8x USB (incl. Thunderbolt 4), providing ample connectivity for peripherals, external storage, and high-speed devices.
Pros & Cons
Pros
- Strong 14+1 power delivery for reliable performance
- WiFi 6E provides fast, reliable wireless networking
- Thunderbolt 4 support for ultra-fast data transfer and peripherals
- 5 Gigabit Ethernet for high-speed wired networking
- PCIe 5.0 GPU slot for next-generation graphics card bandwidth
Cons
- Premium pricing that may be hard to justify for non-enthusiasts
- Only 2 DIMM slots limits memory expandability
- Limited expansion due to single PCIe slot
Who Should Buy This Board?
Small form factor enthusiasts building compact PCs. Ideal for living room gaming rigs, portable LAN systems, or minimalist desk setups where space is limited but performance cannot be compromised.
Build Tips & Recommendations
- Use an LGA 1700 compatible cooler or an adapter bracket. Most modern tower coolers and AIOs include LGA 1700 mounting hardware.
- Enable XMP 3.0 in BIOS to run your DDR5 kit at rated speeds. DDR5-6000 to DDR5-6400 offers the best performance-per-dollar for most users.
- Install your primary NVMe SSD in the top M.2 slot closest to the CPU socket for the fastest connection. The 2x M.2 configuration is sufficient for most builds.
- Choose your case carefully — verify CPU cooler height clearance, GPU length, and PSU form factor (SFX vs ATX) before buying components. Cable management is critical in ITX builds.
- Always update to the latest BIOS before installing components for the best compatibility, especially with newer CPUs and RAM kits. Download the BIOS file to a USB drive and use the flashback feature if available.
