The Maxsun Terminator B850M Pro II is a competent budget AM5 motherboard with a solid feature set with average performance, but its current U.S. pricing make it a tough sell. At $199 it's competitive, but above that, better B850M options are available.

Maxsun isn't that well-known in the U.S, but the China-based company has been around since 2002, and a player in the motherboard game (as well as things like graphics cards and storage) overseas for decades. In that time, it has released some unique motherboard designs, such as the Intel-based iCraft B760M Cross, which features its anime-based brand mascot, Aijia, on the box, with pink and light blue highlights on the white PCB. It was a cool board, but like many of the company's previous samples, it was not without shortcomings.
Today we're testing Maxsun's Terminator B850M Pro II, a budget Micro ATX AM5 board that sports a black aesthetic and is generally well-equipped for a small-form-factor motherboard. You get support for the latest flagship-class processors like the Ryzen 9 9950X3D2 (as well as future AM5 processors), Wi-Fi 7 and 2.5 GbE networking, three M.2 sockets (two PCIe 5.0 x4) and two SATA ports for storage, and room for expansion with two full-length PCIe slots. I would like to see faster USB ports (the fastest is only 10 Gbps) and perhaps a better audio codec, but this board is otherwise comparable to similarly priced B850M options.
The performance portion of our testing went smoothly, but results were average to below average, depending on the test. The Terminator B850M Pro II was competent at gaming and some of the single/lightly threaded tests, mixing in with most other boards, but was slower in heavily multi-threaded tests with our Ryzen 9 9900X.
Below, we’ll examine the B850M Pro II’s performance and other features, although as you have probably guessed from the score above, it won't make it to our list of the best motherboards . But before we share test results and discuss details, here are the specifications from the Maxsun website:
