Built with a USB 3.1 controller, the A88XM-A/USB 3.1 FM2+ Micro ATX Motherboard from ASUS is designed to fit in cases that support a Micro ATX form factor. The 9.3 x 8.2" A88XM-A/USB 3.1 supports AMD Athlon/A-Series processors, the FM2+ socket, as well as the AMD A88X (Bolton D4) chipset. This motherboard supports Windows 10 (64-bit), 8.1 (32/64-bit), 7 (32/64-bit), and XP (32-bit).

The Micro ATX form factor of the A88XM-A/USB 3.1 has 4 x DIMM slots that can support up to 64GB of non-ECC unbuffered DDR3 RAM, as well as dual channel memory architecture and AMD Memory Profile (AMP) memory modules. The supported memory speeds are 2400 (O.C.), 2133, 1866, 1600, and 1333 MHz memory modules. This motherboard has a total of 6 x SATA III 6 Gb/s ports. It also has 1 x PCIe 3.0/2.0 x16 slot, 1 x PCIe 2.0 x1 slot, 1 x PCI slot, 2 x USB 3.1 Type-A ports, 4 x USB 3.0/2.0 ports (2 at the back panel, 2 at mid-board), and 6 x USB 2.0/1.1 ports (2 at the back panel, 2 at mid-board). Using the Realtek ALC887 8-Channel High Definition audio codec, this motherboard can support 8-channel HD audio.

The A88XM-A/USB 3.1 has integrated AMD Radeon graphics support within its A-Series APUs with one HDMI, one DVI, and one RGB output. Its HDMI port supports a max resolution of 4096 x 2160 @ 24 Hz or 1920 x 1200 @ 60 Hz, its DVI port supports a max resolution of 2560 x 1600 @ 60 Hz, and its RGB port supports a max resolution of 1920 x 1600 @ 60 Hz. The integrated graphics can use up to 2,048MB of shared memory and also supports AMD Dual Graphics technology.

ASUS has also designed the A88XM-A/USB 3.1 with LANGuard, DRAM overcurrent protection, DIGI+ VRM, a stainless steel back I/O, ESD guards, AI Suite 3, and more. This motherboard is protected by a limited 3-year warranty and includes an I/O Shield, two SATA III 6 Gb/s cables, and one SCD.

APU & Chipset Features

AMD A88X FCH (Bolton D4)
AMD A88X FCH (Bolton D4) is designed to support interface speeds of up to 5 GT/s and PCI Express 2.0 graphics. It natively supports 8 x SATA III 6 Gb/s ports and 4 x USB 3.0 Ports
AMD A-Series Accelerated Processor with AMD Radeon R-Series Graphics
This motherboard fully supports the latest AMD Socket FM2+ Godavari/Kaveri APUs with AMD Radeon R-series graphics and retains compatibility with AMD Socket FM2 (Richland and Trinity) APUs. AMD Socket FM2+ APUs support Microsoft DirectX 12 for incredibly fast and smooth graphics, native PCI Express 3.0 for full-speed expansion, and 4K resolutions via HDMI and DisplayPort connections

5X Protection II

ASUS LANGuard is hardware-level networking protection that employs signal-coupling technology and anti-EMI surface-mounted capacitors, helping to 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
DRAM Overcurrent Protection
Onboard resettable fuses help prevent overcurrent and short-circuit damage. This extends beyond I/O ports to DRAM to safeguard the lifespan of both your system and connected devices
ASUS-exclusive DIGI+ VRM intelligently delivers power to the processor based on real-time demands, helping to reduce energy waste and improving system stability
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
Electrostatic discharge (ESD) can happen suddenly, and its damaging effects are easily underestimated. ASUS ESD Guards are tested to high standards, capable of up to ±10kV for air discharge and ±6kV for contact discharge. ASUS employs an active protective circuit design to help guard systems against electrostatic interference and damage, providing greater component longevity
