Tune It Your Way

Comprehensive controls form the foundation of the ASUS Prime series. The Prime A520 motherboard packs flexible tools to tune every aspect of your system, enabling you to tweak performance settings to perfectly match the way you work – maximizing your productivity.

EPU
With the Energy Processing Unit (EPU), you’ll enjoy system-wide power savings. The EPU automatically optimizes power consumption and maximizes savings with Away mode.

Fan Xpert 2+
Fan Xpert 2+ software provides comprehensive control over system fans. Auto-Tuning mode intelligently configures all parameters with a single click. There’s also an Extreme Quiet mode that reduces chassis fan speeds to below the default minimum to keep your system whisper-quiet when performing light tasks. Fans can also be controlled via the UEFI BIOS.

Digi+ VRM Control
The Digi+ voltage-regulator module (VRM) delivers real-time control over voltage droop, automatically switching frequency and power-efficiency settings. It also allows you to fine-tune your CPU for ultimate stability and performance.

Cool to the Core
PRIME A520M-A II is engineered with multiple onboard heatsinks and an array of hybrid fan headers to ensure your rig stays cool and stable under intense workloads.

VRM Heatsink and Thermal Pad
A VRM heatsink with underneath thermal pad improves heat transfer from the MOSFETs for better cooling performance.

Cooler by Design

Prime A520M-A II is engineered with an array of hybrid fan headers and features comprehensive cooling controls that are configurable via Fan Xpert 2+ software or via the UEFI BIOS, ensuring your rig stays cool and stable under intense workloads.

• • Multiple Temperature Sensors Each header can monitor and react to dedicated thermal sensors.

• • Smart Protection A dedicated integrated circuit protects the fan headers, including short circuit and over temperature protections.

• • 4-Pin PWM/DC Fan A dedicated integrated circuit protects the fan headers, including short circuit and over temperature protections.

Build on a Solid Foundation

Prime A520 motherboard provides all the fundamentals to boost daily productivity, so your system will on with stable power, intuitive cooling and flexible transfer options.

PCIe 3.0 M.2 (Up to 32 Gbps)
M.2 slot supports up to 22110 and data-transfer speeds of up to 32 Gbps via x4 PCI Express® 3.0 bandwidth. It’s the perfect choice for an operating system or application drive, providing fast access to data.

USB 3.2 Gen 1 Type A
Numerous USB ports support high-end rigs loaded with peripherals, including four rear-panel USB Type-A connectors with fast USB 3.2 Gen 1 connectivity for compatible cases.

Little Things Make a Big Difference

Prime A520 series adds the nuanced details that improve every experience, from exclusive codecs that provide pristine audio quality to intuitive interface that let you customize your system to create a unique personal look.

Outstanding Audio

Combined onboard features deliver elevated audio Intelligent design and premium hardware create audio quality unlike anything you’ve ever experienced.

• • Audio Shielding Separates analog/digital signal domains, significantly reducing multi-lateral interference.

• • Separate Layer for Left and Right Tracks Ensures minimal crosstalk between audio paths.

• • Premium Japanese Capacitors Premium parts provide an immersive sound signature, with exceptional fidelity.

Aura Sync
Outshine the Competition A well-tuned enthusiast system deserves a matching aesthetic. ASUS Aura offers full RGB lighting control with a variety of functional presets for RGB LED strips connected to the onboard RGB headers. And it can all be synced with an ever-growing portfolio of Aura-capable hardware.

Addressable Gen 2 RGB Header
The addressable Gen 2 RGB header is now capable of detecting the number of LEDs on second-gen addressable RGB devices, allowing the software to automatically tailor lighting effects to specific devices. The new header also offers backward-compatibility with existing Aura RGB gear.

Armoury Crate
Armoury Crate is a new software utility designed to give you centralized control of supported products, from a single intuitive interface. Armoury Crate provides control of settings for ASUS products, including keyboard and mouse preferences. This software even features dedicated product registration and highlight to help you stay in touch with the ASUS community.

SafeSlot Core
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 1.6x stronger retention and 1.3x greater shearing resistance than standard expansion slots.

Overvoltage Protection
An exclusive circuit design with built-in voltage regulators to protect your motherboard from damage caused by unexpected high-level voltages from unstable or inferior power supplies.

DRAM Overcurrent Protection
Onboard resettable fuses prevent overcurrent and short-circuit damage. This extends beyond I/O ports to DRAM to 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 three times longer than ordinary panels.

LANGuard
ASUS LANGuard is a hardware-level network protection feature that integrates advanced signal-coupling technology and premium anti-EMI surface-mounted capacitors to improve throughput and ensure a more reliable connection.
