MSI B850 Gaming Plus WiFi (AM5, ATX, Wi-Fi 7)

Our analysis

Both this board and the GIGABYTE B650 Eagle AX are AM5 ATX boards with four DDR5 slots and three M.2, so the gap is in the connections: Wi-Fi 7 against Wi-Fi 6E, a 5 GbE port, and a 10 Gbps rear USB-C against 5 Gbps on the Eagle. With an internet plan above a gigabit, that wired port is the part that decides it.

What stands out

• 5 GbE and Wi-Fi 7. Useful if your internet plan or home network goes beyond a gigabit, so the board is not the slowest link.
• A twelve-way VRM. Power delivery sized for the Ryzen 7 and Ryzen 9 chips this board is meant for.
• A steel-reinforced PCIe 5.0 x16 slot. The graphics card gets the newest slot generation and a sturdier slot to sit in.
• Four DDR5 slots, up to 256 GB. Plenty of capacity if you also work or create on the same PC.

Where it falls short

• The third M.2 runs at Gen4 x2, half the lanes of the other two, which are Gen5 x4 and Gen4 x4.
• The 8200+ MT/s memory figure carries a 1DPC 1R note: it assumes two sticks, not four.
• Rear USB-C tops out at 10 Gbps, and no USB4 is listed.

None of this is a flaw, just the usual trade-offs at this tier, and you should know them before paying.

Look elsewhere if

You need four full M.2 slots or USB4: the GIGABYTE X870 AORUS Elite WiFi 7 has both. If you want a faster rear USB-C and heatsinks on all three M.2, the ASUS TUF Gaming B650E-PLUS WiFi brings a 20 Gbps port.
