The mid-range AM5 staple
MAG X870 Tomahawk WiFi
The Tomahawk formula on X870: dual USB4, Wi-Fi 7, four M.2 and a 14+2+1 VRM at a price that leaves budget for the GPU.
Our verdict
The X870 Tomahawk is the board you buy when you want to stop thinking about the board: every modern port, a VRM with headroom, and MSI's tool-free EZ-DIY touches, all in the low-$200s. It is the default mid-range AM5 pick. Note it is the X870 (non-E) - the pricier X870E Tomahawk is a different board.
Best for: Mainstream Ryzen 9000 gaming builds that want modern I/O without premium-board pricing.
Skip it if: You need x8/x8 dual-GPU lanes or more than one Gen5 M.2 running flat out - that is X870E territory.

Why buy it
- Dual USB4 40Gbps, Wi-Fi 7 and 5GbE at a mid-range price
- Four M.2 slots (two Gen5) with tool-free heatsink latches
- 14+2+1 80A power stages - more VRM than the class needs
Think twice if
- M.2_2/M.2_3 share lanes with USB4 - plan your SSD layout
- Fourth M.2 slot is only PCIe 4.0 x2
- No physical power button for open-bench tinkerers
What reviewers say
KitGuru
8.5/10Solid value with WiFi 7, strong VRM performance, and user-friendly installation features - it 'does a good job and has no obvious problems.' Criticisms: the fourth M.2 slot has limited utility and there is no physical power button.
Full review ↗The FPS Review
8/10Solid construction and a comprehensive feature set at a competitive price. The one gripe is M.2_2/M.2_3 performance compromises from lane-sharing between storage and USB4 that builders must navigate carefully.
Full review ↗Club386
4.5/5 - Editor's Choice'An improved design, better specs, and competitive price make this motherboard a must buy,' though performance gains over the X670E predecessor are only incremental.
