About MSI MAG B550 Tomahawk ATX Motherboard AM4

A tried-and-true ATX motherboard designed for gamers and builders who require performance, thermal stability, and future-ready support is the MSI MAG B550 Tomahawk. It is compatible with Ryzen 3000 (apart from 3200G/3400G), 4000 G-Series, and 5000 series CPUs on the AM4 platform, and it is based on AMD’s B550 chipset.

With speeds of up to 5100 MHz (OC) and support for up to 128 GB of DDR4 RAM, this board is perfect for multitasking, gaming, and memory-intensive tasks. It has two PCIe x16 slots, the main one of which supports PCIe 4.0 (when a Ryzen 3000 or later CPU is being used), guaranteeing complete compatibility with contemporary GPUs. Six SATA 6 Gb/s ports for conventional drives and two M.2 slots—one with Gen4 speeds and thermal shielding—are included for storage.

Realtek 2.5G LAN and an extra Gigabit LAN port manage networking, providing you with extremely low latency and redundancy in network connections. Realtek’s high-end 7.1-channel codec, which features isolated circuitry and premium capacitors for immersive sound output, powers audio.

With large extended heatsinks, premium thermal pads, and a 6-layer PCB with 2 ounces of copper for steady power delivery, cooling is yet another area of strength. Features like the Flash BIOS Button, EZ Debug LEDs, and an integrated I/O shield will be valued by builders. The MSI MAG B550 Tomahawk offers the speed, robustness, and adaptability required to push your system to its limits, whether you’re building a professional workstation or a potent gaming PC.
