Tuned to your needs
The core attribute of the ASUS PRIME series motherboards is comprehensive control. The PRIME A520 model includes flexible tools to customise every aspect of your system. These let you tune performance to perfectly match your workflow and boost productivity.
All-round energy efficiency
With the Energy Processing Unit (EPU), you can enjoy system-wide power savings. The EPU automatically optimises power consumption and maximises savings with Away Mode.
Flexible control options
ASUS Fan Xpert software provides comprehensive control over your fans. Auto-Tuning mode intelligently configures all parameters with a single click. There's also an extremely quiet mode that reduces chassis fan speeds below the default minimum, keeping your system whisper-quiet during light tasks. Fans can also be controlled via the UEFI BIOS.
Precise digital voltage control
The Digi+ voltage-regulator module (VRM) provides real-time control over voltage droop, automatically switching frequency and power-efficiency settings. It also lets you fine-tune your CPU for ultimate stability and performance.
Advanced tuning for advanced users
The intuitive Advanced mode, offered via the UEFI, lets you take complete control. A built-in search function makes it easy to find options, and various advanced functions let you make intelligent, detailed adjustments, so you can dial in performance exactly the way you want.
Quick and easy setup
EZ mode displays vital settings and stats and also offers guided wizards, drag-and-drop functionality, and a one-click application of important settings—all to help you get your rig up and running in no time.
Advanced cooling options for the PRIME A520
The PRIME A520 series motherboards feature comprehensive cooling controls that are configurable via Fan Xpert software or through the UEFI BIOS. Each header can dynamically reference three thermal sensors, and Fan Xpert lets you map the temperature of supported ASUS graphics cards to optimise cooling for GPU and CPU-intensive tasks. A dedicated integrated circuit also protects each fan header from overheating and overcurrent, and each onboard header supports auto-detection of PWM or DC fans.
ASUS A520 – the motherboard for everyday productivity
The ASUS A520 motherboard offers stable power, intuitive cooling, and flexible data transfer options to boost your daily productivity. The M.2 slot supports speeds of up to 32Gb/s via PCI Express® 3.0, enabling faster boot and load times for your system and applications. With multiple USB ports, including USB Type-A with fast 5Gb/s USB connectivity, the board can handle high-end builds with many peripherals. Realtek 1Gb Ethernet reduces CPU overhead, ensures high TCP and UDP throughput, and provides smoother data transfer. Network reliability is handled by ASUS LANGuard, which combines signal-coupling technology with premium capacitors and EMI protection.
Customisation and excellent sound
The PRIME A520 series adds subtle details that enhance everyday use, from exclusive codecs providing pristine audio quality to an intuitive interface for a unique system look. The combination of onboard features delivers elevated audio through intelligent design and premium hardware. Audio shielding ensures precise analogue/digital separation and reduces interference, dedicated audio PCB layers provide consistent quality for both channels, and premium capacitors deliver warm, natural, and immersive sound with exceptional clarity and fidelity.
Armoury Crate
Within a single intuitive interface, Armoury Crate offers easily customisable settings for every compatible device in your arsenal, plus controls for the ever-expanding family of ASUS products, including keyboard and mouse preferences. Armoury Crate also integrates product registration and a news feed, so you'll never miss updates that are interesting to the ASUS community.
DIY-friendly – Q-LED Core and SafeSlot Core
The Q-LED Core display produces light patterns via the power LED during the Power-On Self-Test (POST) that help with troubleshooting. A fast 4Hz (0.25s) flash indicates 'CPU not detected', a slow 1/2Hz (2s) flash indicates 'VGA not detected', a very slow 1/8Hz (8s) flash indicates 'boot device not detected', and a steady light means the installation is complete. SafeSlot Core is ASUS's exclusive PCIe slot, featuring a reinforced design anchored by a special hook. It provides 1.6× stronger retention and 1.3× greater shear resistance than standard expansion slots.

Choosing a motherboard
When choosing a motherboard (or mainboard), it is important to pay particular attention to the motherboard's socket type, form factor, and chipset. These parameters are among the most important and ensure the board's compatibility with the processor, expansion cards, and other components. The specific socket will determine the choice of a suitable processor, while the other connectors will dictate the selection of other components for your future computer.Specifications
