The B450-A Gaming Plus AM4 ATX Motherboard from MSI is built on the AMD B450 chipset, supporting AMD Ryzen series and A-Series/Athlon processors with an AM4 socket. It has four RAM slots that can hold up to 64GB of dual-channel DDR4 memory at speeds of up to 3466 MHz when overclocked. For storage, there are six SATA III ports and a single M.2 slot that can operate at up to 32 Gb/s when used with a compatible NVMe drive. While this motherboard is equipped with DVI-D and HDMI ports for onboard graphics, it also has a PCIe 3.0 x16 slot for a dedicated GPU as well as a PCIe 2.0 x16 and four PCIe 2.0 x1 slots for additional PCIe-based hardware. Other notable features include Realtek ALC892 7.1-channel HD audio and Realtek 8111H Gigabit LAN.

Cooling
This motherboard is equipped with six fan headers that support both DC and PWM modes, so you adjust their speeds either manually or automatically within BIOS or a third-party software to find a balance between cooling and noise.
Audio
MSI Audio Boost consists of both hardware and software additions that are designed to provide you with a high-quality listening experience. The left and right channels are built on separate PCB layers, De-Pop Protection prevents loud popping noises, an EMI-shielded audio processor ensure clean stereo and surround sound, and a dedicated headphone amplifier automatically detects the optimal impedance for your headphones. For gaming, Nahimic 3 provides you with virtual surround sound with an in-game overlay that displays where noises are coming from.
Storage
There are six SATA III ports on this motherboard designed for traditional 2.5" and 3.5" drives. Moreover, it's also equipped with a single M.2 slot that can utilize the PCIe 3.0 x4 interface for speeds up of up 32 Gb/s when used with a compatible NVMe drive. For an additional boost in performance, you can enable X-Boost within MSI's software.
Memory
The DDR4 memory slots on this motherboard are built with an optimized memory layout to offer stability, performance, and low power consumption. Additionally, this motherboard supports XMP for enhanced RAM speeds. Please note that A-series/Athlon processors support up to 2400 MHz, and the supporting frequency of memory varies with installed processor.
