Product information
Top features:

- Upgrade your components with loads of connectivity

- Take control of your cooling with six fan headers

- Customise your lighting with RGB connections  

Upgrade your components

The MSI B450 TOMAHAWK AM4 Motherboard is built to give you loads of options, whether this is your first build or an upgrade. Compatible with the latest M.2 storage, you can add superfast SSD storage to your build - boot up in seconds and reduce the time you're stuck waiting for games to load. And because your SATA ports are freed up, you can pile up huge capacity hard drives.

The AM4 socket is compatible with Ryzen processors, so you can upgrade through the range over time, or jump straight to a powerful Ryzen 7 CPU for your initial build.

Take control of your cooling

When you've got your cooling set up, you want to be able to adjust everything accurately. Which is why the MSI TOMAHAWK Motherboard has six fan headers with full controls and an extended heatsink. There's also compatibility for water cooling, so even with loads of great components, it's easy to keep everything cool.

Customise your lighting

Customise your PC with RGB lighting - the TOMAHAWK features MSI Mystic Lighting, so you can personalise the lighting on the motherboard, and connect all your other RGB components. It's easy to choose from a huge palette of colours and effects, so your entire PC can glow in the same rainbow hues, or flash at the same time.
