Platform foundation

The MAG X870E TOMAHAWK WIFI is an ATX motherboard built around the AMD X870E chipset and AM5 socket. It supports AMD Ryzen 9000, 8000 and 7000 series desktop processors with a 14 Duet Rail power system rated at 80A per smart power stage. Dual 8-pin CPU power connectors feed the digital PWM for sustained heavy loads.

Fit and alternatives

This board suits builders who want PCIe 5.0 graphics and storage, 5G LAN, Wi-Fi 7 and a USB 40G port in a single ATX package. Four DDR5 slots and four M.2 sockets give expansion headroom. Users needing ECC memory, workstation chipsets or smaller form factors should look elsewhere.

Capacity and headroom

DDR5 runs up to 8400 MT/s overclocked with a 256 GB ceiling across four slots in dual-channel mode. The primary M.2 slot from the CPU delivers PCIe 5.0 x4 bandwidth for 22110 and 2280 drives, while two additional CPU-linked slots and one chipset slot add further Gen5 and Gen4 capacity. Realtek ALC4080 handles 7.1-channel audio at 32-bit/384 kHz.

Questions about this item

Will this board fit in a standard ATX case and does it need any special mounting?

The board uses the ATX form factor, so any case that accepts ATX motherboards will fit it with the usual nine standoffs and I/O shield.

Which Ryzen processors are supported and is a BIOS update ever required?

It supports Ryzen 9000, 8000 and 7000 series CPUs on socket AM5; 9000 series chips may need a newer BIOS version than the one shipped from the factory.

How many M.2 drives can I install and which slots run at Gen 5 speed?

Four M.2 slots are provided; the top two are wired to the CPU and run at PCIe 5.0 x4, while the lower two run at PCIe 4.0 x4 from the chipset.
