Product Overview

The MAG X870E Tomahawk WiFi steps up from the B850 platform with AMD's X870E chipset, which enables full PCIe 5.0 across both the primary GPU slot and M.2 storage. The headline feature is the dual USB4 40Gbps rear ports — a significant connectivity advantage over B850 boards, enabling Thunderbolt-compatible peripherals, external GPUs, and ultra-fast storage enclosures. The 14+2+1 phase Duet Rail power system on an 8-layer 2oz copper PCB matches the top-tier B850 boards in power delivery quality. Frozr Guard heatsinks with 7W/mK thermal pads keep the VRM and M.2 slots cool under sustained load. ALC4080 audio delivers 32-bit/384kHz quality. EZ Debug LED and EZ Digit Debug LED simplify troubleshooting. Flash BIOS and Clear CMOS rear buttons are included for easy setup and recovery.
