Socket AM4 board for Ryzen builds

The MSI B450 GAMING PLUS is an ATX motherboard built around the AMD B450 chipset and Socket AM4. It supports first- and second-generation Ryzen processors and Ryzen models with integrated Radeon Vega graphics. Dual-channel DDR4 memory up to 64 GB runs at speeds from 1866 to 3466 MHz.

Suits AM4 owners wanting solid I/O

This board fits builders staying on the AM4 platform who need 7.1-channel Realtek ALC892 audio, a Realtek 8111H Gigabit LAN port and ten rear USB ports including two 10 Gbps Type-A connectors. Buyers needing newer Ryzen support or additional M.2 slots should look at something else.

One x16 PCIe 3.0 slot decides GPU bandwidth

The primary PCIe 3.0 x16 slot delivers x16 electrical speed with first- and second-generation Ryzen CPUs and x8 speed with Ryzen Vega APUs. A second x16 physical slot operates at x4 over PCIe 2.0, while four x1 slots and six SATA III ports handle extra cards and drives.

Questions about this item

How do I fit the AM4 cooler bracket on the MSI B450 GAMING PLUS without bending the back-plate?

The board uses the standard AM4 retention frame; keep the plastic back-plate flat against the rear of the board while you tighten the spring screws in a cross pattern so it seats evenly.

What component on the MSI B450 GAMING PLUS will need replacement first during long-term use?

The socketed CMOS battery supplied in the box will eventually lose charge; when the clock drifts or BIOS settings reset, replace it with an identical coin cell.

Which limit appears first when the MSI B450 GAMING PLUS runs sustained heavy loads?

The VRM heatsink is the first thermal bottleneck; under prolonged all-core workloads the MOSFET temperatures rise before the chipset or audio sections become critical.
