The ASUS PRIME A520M-A II/CSM is a micro ATX motherboard designed for AMD Ryzen processors using the AM4 socket and AMD A520 chipset. Part of the ASUS Prime series, it combines a robust power design, comprehensive cooling, flexible system tuning and a broad selection of connectivity options for everyday users, business systems and DIY PC builders. It supports compatible Ryzen 3000 Series, 3000 G-Series, 4000 G-Series, 5000 Series and 5000 G-Series processors, with support for one processor.
As an ASUS Corporate Stable Model, the PRIME A520M-A II/CSM is part of a commercial programme intended to provide organisations with a stable and reliable motherboard platform. The CSM programme offers up to 36 months of product lifecycle support together with six months of end-of-life notice, providing additional lead time when preparing for product transitions. Purchase of an ASUS CSM motherboard also includes ASUS Control Center Express, ASUS server-grade IT management software.
ASUS Control Center Express provides integrated IT monitoring and management capabilities intended to simplify IT operations, assist with faster deployment and provide comprehensive system control through user-friendly functions. The software is compatible with more than 100 ASUS motherboard models and is designed to provide businesses with a total-cost-of-ownership-optimised management solution.
The motherboard provides comprehensive controls for configuring and tuning the system. Its software and firmware tools allow different aspects of system performance to be adjusted to suit the way the computer is used. Cooling is supported through multiple onboard heatsinks and hybrid fan headers, while the VRM heatsink design contributes to the motherboard's cooling configuration during demanding workloads.
Four 288-pin DIMM slots provide support for up to 128GB of unbuffered DDR4 memory using a dual-channel memory architecture. ECC integrity checking is supported. Memory speeds include 2133MHz, 2400MHz, 2666MHz, 2800MHz, 2933MHz, 3000MHz and 3200MHz, with overclocked memory frequencies ranging from 3333MHz up to 4800MHz also supported.
For storage, the PRIME A520M-A II/CSM provides four SATA-600 connectors with support for RAID 0, RAID 1 and RAID 10. It also includes an M.2 Key M socket supporting 2242, 2260 and 2280 M.2 devices. The M.2 connection supports SATA-600 and PCI Express 3.0 connectivity, with PCIe 3.0 x4 bandwidth providing data transfer speeds of up to 32Gbps. This gives the motherboard an onboard high-speed storage connection suitable for an operating system or application drive where fast access to stored data is required.
Expansion connectivity includes one PCIe 3.0 x16 slot and two PCIe 3.0 x1 slots. The motherboard also provides four DIMM slots and the M.2 socket alongside its CPU socket, giving the platform a range of options for memory, storage and expansion hardware.
A broad selection of external connections is provided on the motherboard, including VGA, DisplayPort and HDMI display outputs. Onboard graphics output requires a compatible CPU with graphics capability. USB connectivity includes four external USB 3.2 Gen 1 ports and two external USB 2.0 ports. Internal USB headers provide additional USB 3.2 Gen 1 and USB 2.0 connectivity. The rear connections also include Gigabit Ethernet, a PS/2 keyboard and mouse connection, microphone input, audio line-in and audio line-out.
Network connectivity is provided through Gigabit Ethernet, while ASUS LANGuard is among the motherboard's integrated hardware features. The board also supports Wake on LAN and wake on PME, along with Preboot eXecution Environment functionality.
The integrated eight-channel HD Audio system uses a Realtek ALC887/ALC897 audio codec and complies with the High Definition Audio standard. ASUS combines its audio implementation with hardware and codec features designed to provide high-quality onboard sound without requiring a separate audio card for the motherboard's integrated audio functionality.
The PRIME A520M-A II/CSM uses an AMI BIOS and includes UEFI BIOS functionality, ASUS UEFI BIOS EZ Mode and ASUS EZ Flash 3. Additional motherboard technologies include CrashFree BIOS 3, ASUS EZ DIY, ASUS DIGI+ VRM, ASUS 5X Protection III, overvoltage protection, ASUS SafeSlot Core, ASUS Stainless Steel Back I/O, ASUS Q-Design, Q-DIMM and Q-Slot. ASUS Aura Sync and Lighting Control are also supported for compatible lighting customisation.
Internal connectivity extends beyond storage and USB, with headers for SPI, SPDIF output, audio, serial connectivity and a speaker. Power is supplied through a 24-pin main power connector and an 8-pin ATX12V connector.
The micro ATX motherboard measures 24.4cm wide by 24.4cm deep. Included with the ASUS PRIME A520M-A II/CSM are two Serial ATA cables, an I/O shield and an M.2 screw package. The supplied software selection includes WinRAR, a trial version of Norton AntiVirus, DAEMON Tools, ASUS AI Charger, ASUS CPU-Z, ASUS EZ Update, ASUS Fan Xpert 2+, ASUS TurboV EVO Utility, ASUS AI Suite III, ASUS AURA Creator and ASUS Control Center Express.
