Product Description
The MSI MAG Z790 TOMAHAWK MAX WIFI LGA1700 ATX Motherboard is a flagship-tier military-styled desktop platform designed for hardcore gamers, competitive overclockers, content creators, and PC enthusiasts who demand maximum electrical stability and cutting-edge I/O bandwidth from Intel 14th, 13th, and 12th Generation Core processors. Built around an ultra-durable 6-layer server-grade PCB infused with 2oz thickened copper, the board features a stealth matte-black aesthetic with heavy plated industrial heatsinks that maintain optimal thermal equilibrium under prolonged maximum computing loads.
Power delivery is driven by a robust 16+1+1 Duet Rail Power System (DRPS) featuring 90A Smart Power Stages (SPS) and dual 8-pin CPU power inputs. This elite VRM topology delivers clean, high-amperage current to unlock peak multi-core boost clocks during intensive gaming, 3D rendering, and compiling. Memory capabilities are accelerated via MSI Memory Boost and isolated trace routing, supporting up to 192GB of dual-channel DDR5 across 4 DIMM slots with aggressive overclocking speeds reaching 7800+ MHz (OC) via Intel XMP 3.0 profiles.
Storage and expansion architectures are fully future-proofed. The primary graphics slot utilizes PCIe 5.0 x16 technology with Steel Armor shielding to handle the heaviest modern GPUs without physical bending or electrical interference. Storage is expansive, highlighted by a dedicated Gen5 M.2 slot providing PCIe 5.0 x4 bandwidth (up to 128Gbps), complemented by 3 additional high-speed PCIe 4.0 x4 M.2 slots and 8 SATA 6Gb/s ports. All M.2 slots are cooled by MSI's double-sided M.2 Shield Frozr system, with the primary slot featuring a patented screwless mechanism and EZ M.2 clips for fast, tool-free SSD swaps.
Networking is upgraded to next-generation Wi-Fi 7 technology featuring wide 320MHz channel bandwidths and transfer speeds up to 5.8Gbps, paired with an easy-snap EZ Antenna and Bluetooth 5.4, alongside an Intel 2.5Gbps high-speed Ethernet controller for latency-free competitive online play. Studio-grade audio is delivered by the Realtek ALC4080 USB audio processor with dedicated high-grade capacitors and optical S/PDIF out. Outfitted with dual rear USB Type-C ports (including a 20Gbps USB 3.2 Gen 2x2 port), physical Clear CMOS and Flash BIOS buttons, and an official 3-year warranty, the MSI MAG Z790 TOMAHAWK MAX WIFI stands as the premier foundation for modern high-performance desktop builds.
