My MSI PRO B650 motherboard has had serious problems since day one, and returning it is extremely difficult because I live in the Maldives. The onboard Ethernet, Wi-Fi, Bluetooth, and four USB 3.0 ports regularly disconnect or stop working. I can only use the PC reliably after disabling Bluetooth, Ethernet, and Wi-Fi and avoiding those four USB ports, leaving me with just three usable USB ports. For internet access, I currently use a separate Ethernet adapter.
The board also frequently hangs on the orange memory-related debug light after restarting or waking from sleep. Adjusting the SoC voltage in the BIOS can resolve that issue, but then the USB ports become unreliable, including the ports that already have problems. I have already tried BIOS updates, power-management changes, disabling power-down features, USB hubs, fully draining the system, and checking the RAM, PSU, and GPU. The system is stable for gaming when the affected motherboard features are disabled.
I want to replace only the motherboard and need a dependable B850 ATX model with plenty of reliable USB connectivity for a microphone, camera, and other peripherals. I plan to keep using my Ryzen 5 7600X, Radeon RX 9070 XT, existing RAM, and full-tower ATX case. I am considering Gigabyte boards, although the MSI MAG B850 MAX is also tempting. After these problems, I am unsure whether I should buy MSI again. What models would you recommend, and are there any Ethernet controllers or motherboard features I should avoid?

Before choosing a board, check the exact CPU, memory kit, graphics card, storage, case, and peripheral requirements. The number and type of USB ports, fan headers, and the board’s rear-I/O layout can vary quite a bit. Since you are keeping the Ryzen 5 7600X, RX 9070 XT, and full-tower ATX case, focus on a well-supported ATX model with enough USB ports and a good return or warranty option. No motherboard can guarantee zero firmware or USB problems, so checking recent owner reports is worthwhile.
Pay close attention to the onboard Ethernet controller rather than choosing solely by brand. Intel 2.5GbE controllers such as the I225 and I226 have been associated with intermittent connection problems on some boards. If possible, choose a model using a different controller, or at least confirm that the specific board has a stable, well-supported revision and current drivers. Also verify the exact USB controller layout, because several rear ports may share a controller or internal connection.
That is helpful. I will check the Ethernet chipset and the USB controller layout before deciding, instead of assuming a different brand automatically solves the problem.
I am only replacing the motherboard. The rest of the system is staying the same for now: Ryzen 5 7600X, Radeon RX 9070 XT, and a full-tower ATX case. My main priorities are reliable networking and having enough dependable USB ports for future peripherals.
