MSI MAG X870E TOMAHAWK MAX WIFI AMD X870E ATX Motherboard — AM5 | DDR5 | PCIe 5.0 | Wi-Fi 7 | 5G LAN | USB 40Gbps | AI PC Ready

The MSI MAG X870E TOMAHAWK MAX WIFI is built for enthusiast gamers, content creators, AI PC builders, and performance-focused system integrators deploying AMD Ryzen 9000, 8000, or 7000 Series processors who want the full X870E feature set — PCIe 5.0 GPU and NVMe, Wi-Fi 7, 5G LAN, USB4, comprehensive memory overclocking with AMD EXPO, and a robust 14-phase VRM — alongside MSI's industry-leading EZ DIY accessibility for a smooth, screwdriver-free build experience. Well-suited for 4K and 8K gaming rigs, rendering and AI workstations, streaming PCs, and future-ready platform builds.

The MAG X870E TOMAHAWK MAX WIFI is powered by a 14+2+1 Duet Rail Power System with 80A Smart Power Stage MOSFETs, dual 8-pin CPU power solid-pin connectors, Core Boost, Extended Heatsink with 7W/mK thermal pads, Heavy Plated VRM Heatsink, additional choke thermal pads, and an 8-layer 2oz copper server-grade PCB — delivering sustained clean power delivery for Ryzen 9000 Series processors at stock and overclocked operation. OC Engine provides a dedicated independent BCLK control chip enabling asynchronous Base Clock adjustments for up to 15% additional gaming performance gains without destabilising memory, PCIe, or NVMe subsystems. Four DDR5 DIMM slots support up to 256GB at DDR5-8400+ (OC) via AMD EXPO and A-XMP profiles with Latency Killer for up to 12% memory latency reduction, High-Efficiency Mode, and Memory Try It!! for automated timings. Two PCIe 5.0 x4 CPU-direct M.2 slots support NVMe Gen 5 SSDs at 128 Gbps each alongside two PCIe 4.0 x4 chipset M.2 slots — all with EZ M.2 Shield Frozr II for thermal protection and EZ M.2 Clip II for tool-free SSD installation. The PCIe 5.0 x16 GPU slot with Steel Armor II reinforcement and PCIe Supplemental Power connector delivers full-bandwidth ATX 3.1 and PCIe 5.1-ready GPU support for the highest-TDP current and next-generation graphics cards. Wi-Fi 7 (802.11be) with MU-MIMO across 2.4/5/6 GHz up to 5.8 Gbps and Bluetooth 5.4 provides the fastest available wireless connectivity, while Realtek RTL8126 5G LAN ensures ultra-fast, low-latency wired networking with AI LAN Manager traffic prioritisation. Two USB4 40Gbps Type-C ports on the rear panel provide the fastest USB connectivity for external SSDs, docking stations, and displays, complemented by front USB 20Gbps Type-C with 27W PD Super Charger+ for fast charging PD-compatible devices. Realtek ALC4080 Audio Boost 5 delivers 7.1-channel USB HD audio at up to 32-bit/384kHz with dedicated headphone amplifier, isolated audio PCB, and Isolated Analogy Structure for clean, professional audio. MSI's full EZ DIY suite — EZ M.2 Clip II, EZ PCIe Release, EZ Antenna with magnetic stand, Flash BIOS button, Clear CMOS button, Pre-installed I/O Shield, EZ Conn header, EZ Mounting, EZ Debug LED, EZ Digi-Debug LED, EZ Memory Detection LED, and colour-coded headers — minimises build friction at every step.
