The A320M Bazooka AM4 Motherboard from MSI features an AM4 socket, a micro-ATX form factor, a PCIe 3.0 x16 slot, and four DIMM slots, so you can build a compact AMD-based gaming system with up to 64GB of DDR4 RAM. With an AMD A320 chipset, the A320M Bazooka is compatible with AMD's series of RYZEN along with 7th-generation A and Athlon processors. For non-gaming builds, the motherboard supports APUs that deliver detailed visuals through its HDMI, DVI-D, and VGA outputs, utilising integrated AMD graphics. Aside from graphics options, one M.2 slot and four SATA connectors are available, letting you instal optical drives, 2.5" hard drives, 2.5" SSDs, and M.2 SSDs with NVMe technology. Additionally, MSI has equipped this motherboard with Mystic Light Sync along with white LEDs on the back to illuminate the insides of your case.

The A320M Bazooka lets you connect with printers, external storage drives, scanners, and more by offering two USB 2.0 and four USB 3.0 ports. There's also a pair of PCIe 2.0 x1 slots that enable you to add additional capabilities, such as Wi-Fi cards, expansion cards, and other PCIe-based cards. Other notable features include a Gigabit Ethernet port and a PS/2 combo port along with Realtek ALC892 audio, which provides 7.1-channel surround sound through the motherboard's three audio jacks.

Key Features

AM4 Socket

AM4 chipsets provide dedicated PCIe lanes for USB, graphics, data, and other I/O.

Personalise Your Gaming Rig

Customise and set up your own colour scheme with RGB Mystic Light Sync. You can select any of the colours from the palette using the MSI Gaming app for smartphones and desktops to match your personal style. This motherboard features LEDs on the back to create a white glow inside your case. For additional lighting inside, a Mystic Light extension header is on board for controlling optional RGB strips, fans, and other gear, without needing a separate RGB controller. Additionally, Mystic Light Sync can also work with select LED-enabled keyboards and mice.


MSI fan headers automatically detect fans running in DC or PWM mode for optimal tuning of fan speeds and quietness. To ensure your system stays silent, hysteresis is also available to make your fans spin up fluently. Total Fan Control software is offered so you can take control of your fans and cheque the system's characteristics in a simplified graphical interface. You can also set up to 4 temperature targets for the CPU and motherboard, which will adjust the fan's speeds automatically.


With premium audio components, this motherboard offers studio grade sound by offering separated audio layers and Chemi-Con audio capacitors as well as an isolated audio design, De-Pop protection, and EMI-shielded HD audio processor.
