Ready for AMD Ryzen, 7th Generation A-Series, and Athlon processors, the PRIME A320M-A AM4 Micro-ATX Motherboard from ASUS delivers customizable performance. 5X Protection III delivers hardware-level safeguards for component longevity and reliability, SafeSlot Core helps prevent damage from heavyweight GPUs, FanXpert delivers controls for optimized cooling, and 8-channel HD audio provides warm and immersive sound with LED illumination. This motherboard is designed to fit in micro-ATX sized cases and supports the AM4 socket and the AMD A320 chipset. This motherboard is compatible with Windows 10 (64-bit).

The micro-ATX form factor of the PRIME A320M-A can support up to 64GB of DDR4 RAM over four dual-channel slots, or 16GB per slot. Ryzen processors can support memory speeds of 3200 (OC), 2933 (OC), 2666, 2400, and 2133 MHz ECC and non-ECC unbuffered memory, while A-Series and Athlon processors support speeds of 2400 and 2133 MHz non-ECC unbuffered memory. Ryzen processors also support up to four SATA III 6 Gb/s ports with compatibility for RAID 0 and 1, while A-Series and Athlon processors support two SATA III 6 Gb/s ports. All processor types also support one M.2 Socket 3, with M key, type 2242, 2260, and 2280 for both SATA and PCIe drives. While Ryzen processors support PCIe 3.0 x4, A-Series and Athlon processors only support PCIe 3.0 x2.

There are also a total of four USB 3.0 Type-A ports (back panel), two USB 3.0 ports (mid-board), two USB 2.0 Type-A ports (back panel), and two USB 2.0 connectors that support an additional four USB 2.0 ports (mid-board). For those looking to expand their system using PCIe, there are two PCIe 2.0 x1 slots. Additionally, Ryzen processors support one PCIe 3.0/2.0 x16 slot (x16 mode) and A-Series & Athlon processors support one PCIe 3.0/2.0 x16 slot (x8 mode).

For delivering sharp, clear graphics, this motherboard supports AMD Radeon R Series Graphics in the 7th Generation A-Series APU with HDMI 1.4b, DVI-D, and VGA outputs. HDMI 1.4b supports a maximum resolution of 4096 x 2160 @ 24 Hz or 2560 x 1600 @ 60 Hz, and both DVI-D and VGA support a maximum resolution of 1920 x 1200 @ 60 Hz. Integrated graphics has access to up to 2048MB of shared memory and users who don't opt for A-Series processors with integrated graphics will need to purchase a compatible dedicated GPU of their choice.

Using the 8-Channel Realtek ALC887 HD audio codec, the PRIME A320M-A can support audio with higher fidelity than standard controllers. Audio can also be output using the integrated three audio outputs or S/PDIF output. PRIME A320M-A AM4 Micro-ATX Motherboard is equipped with features such as SafeSlot Core, LANGuard, overvoltage protection, a stainless steel back, DIGI+ VRM digital power design, AI Suite 3, Ai Charger, Turbo LAN, CrashFree BIOS 3, EZ Flash 3, UEFI BIOS, and more. Included is an I/O shield, two SATA III 6 Gb/s cables, one M.2 screw package, and a supporting DVD. This motherboard is protected by a limited 3-year warranty.

General Features

Reliable Stability and Compatibility

5X Protection III
PRIME A320 series motherboards are engineered with 5X Protection III, employing fine components, excellent circuit design, and exacting standards to help guarantee the quality and long-term durability of your motherboard. That means strong protection and stability for your build.
SafeSlot Core - Fortified PCIe Slot
SafeSlot Core is the ASUS-exclusive PCIe slot. Featuring a fortified design that's anchored to the motherboard by a special hook, SafeSlot Core provides up to a 1.6x stronger retention and up to a 1.3x greater shearing resistance than standard expansion slots. ASUS Prime motherboards have strengthened solder points around both the PCIe and DIMM pins.
LANGuard
ASUS LANGuard is hardware-level networking protection that employs signal-coupling technology and premium anti-EMI surface-mounted capacitors to help ensure a more reliable connection and better throughput, plus electrostatically guarded and surge-protected components for greater tolerance to static electricity and improved protection against surges.
Overvoltage Protection
An exclusive circuit design with built-in voltage regulators to help protect your chipset, connectivity ports, and audio codecs from damage caused by unexpected high-level voltages from unstable or inferior power supplies.
DIGI+ VRM
ASUS-exclusive DIGI+ VRM intelligently delivers power to the processor based on real-time demands, reducing energy waste and improving system stability.
DRAM Overcurrent Protection
Onboard resettable fuses help prevent overcurrent and short-circuit damage. This extends beyond I/O ports to DRAM to help safeguard the lifespan of your system and connected devices.
Stainless-Steel Back I/O
Corrosion-resistant stainless-steel back I/O panels bonded with chromium oxide have a lifespan that's up to three times longer than ordinary panels.
ESD Guards
ASUS ESD Guards help prevent damage from electrostatic discharge, up to ±10kV for air discharge and ±6kV for contact discharge, arranged in an active-protective-circuit design that prolongs the life of components. Protection is provided for the LAN port, USB connectors, VGA connectors, and keyboard/mouse connectors.
