Overview

The MSI MAG X870 TOMAHAWK WIFI is an ATX motherboard built for AMD's Ryzen 9000 series processors, featuring the X870 chipset. It comes with PCIe 5.0 support for the latest GPUs and SSDs, along with integrated 2.5GbE and Wi-Fi 7, making it a well-rounded choice for gamers and creators seeking a reliable mid-range platform.

Key Features

  • AM5 socket compatible with Ryzen 7000, 8000, and 9000 series CPUs
  • DDR5 memory support up to 192GB (4 slots) with overclocking beyond 7200MHz
  • One PCIe 5.0 x16 slot (CPU direct) and one PCIe 4.0 x4 slot (chipset)
  • Four M.2 slots: one PCIe 5.0 x4, three PCIe 4.0 x4 – plus four SATA 6Gbps ports
  • Onboard 2.5GbE LAN and Wi-Fi 7 + Bluetooth 5.4
  • Realtek ALC4080 audio codec with isolated audio traces
  • Large VRM heatsinks and M.2 Shield Frozr for sustained thermal performance

Compatibility Guide

  • CPU Socket: AMD AM5 (Ryzen 7000/8000/9000 series)
  • Memory: DDR5 dual-channel, max 192GB (48GB DIMMs supported)
  • Form Factor: Standard ATX (305mm x 244mm) – fits most mid-tower and full-tower cases
  • Power Connectors: 24-pin ATX + 8+4-pin EPS. An ATX 3.0 compliant PSU is recommended for high-end CPUs
  • Storage: 1x M.2 PCIe 5.0 (CPU), 3x M.2 PCIe 4.0 (chipset), 4x SATA 6Gbps
  • PCIe: Primary slot runs at PCIe 5.0 x16 (CPU), secondary slot at PCIe 4.0 x4 (chipset)

Ideal Builds

  • Building a high-performance gaming PC with Ryzen 7 9800X3D or Ryzen 9 9950X
  • Need PCIe 5.0 support for next-gen GPUs and ultra-fast NVMe drives
  • Want future-proof wireless connectivity with Wi-Fi 7
  • Plan to overclock memory or fine-tune CPU performance

Upgrade Considerations

  • The single PCIe 5.0 x16 slot does not support multi-GPU setups – if you need dual GPUs, consider a higher-end X870E board
  • Using a PCIe 5.0 SSD in the primary M.2 slot does not reduce GPU lane count, but the chipset-connected M.2 slots share bandwidth with other peripherals
  • Large graphics cards (over 350mm) may obstruct some front-panel connectors; check case compatibility before purchasing
  • BIOS updates are needed for Ryzen 8000G APUs and later CPU releases – MSI’s USB Flashback feature allows updates without a CPU
  • Although VRM cooling is robust, a well-ventilated case is recommended for sustained heavy loads
