The MSI A320M Bazooka is a motherboard in micro ATX format and has graphics cards with a fast PCI Express 3.0 slot with full x16 connection. Furthermore, two PCIe-x1 slots are available for other expansion cards. Up to 64 GB of DDR4 memory take up the four RAM banks, with corresponding memory running at a maximum of 2.666 megahertz. The internal connection repertoire includes a header for USB 3.0 and two for USB 2.0 for two or four ports, respectively.
Special features at a glance:
1x PCIe 3.0 x16 for high-end gaming graphics cards
6x USB 3.0 / 6x USB 2.0 / 1x Turbo M.2 slot PCIe 3.0 x4
3x PWM fan ports (4-pin)
DDR4 memory up to 2.666 MHz
Modern UEFI BIOS including temperature monitoring
Such as SSDs and hard disks, the board is managed by four SATA 6G connectors (including RAID support), as well as a horizontal M.2 slot, which is connected to four PCI Express 3.0 lanes, enabling enormous speeds up to To 32 Gbit / s. M.2 SSDs with a length of 42 to 80 mm can be used and the advanced NVM Express protocol, which has been especially optimized for highly parallelized data carrier accesses of modern PCIe SSDs, is supported.
Finally, three fans with a 4-pin PWM connector can be connected directly to the board. On the mainboard back, additional devices and components can be connected to the MSI A320M Bazooka via USB 3.0 and 2.0, Gigabit LAN, universal PS / 2 or three audio jacks for 7.1 sound. In addition, three monitor outputs (HDMI, VGA and DVI-D) are available for the display via an integrated APU graphics unit (optional).

CPU Cooler Compatibility Note on AMD Socket AM4:
Because AM4 (+), AM3 (+) or FM2 (+) predecessors AM4 (+), AM4 (+), AM4 (+) AMP connectors have to be matched to compatible AM4 mounting kits. CPU coolers attached directly to the motherboard's retention module are fully compatible.
