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.
Cooler by design
PRIME A520M-A 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.
Build on a solid foundation
Prime A520 motherboard provides all the fundamentals to boost daily productivity, so your system will be ready for action with stable power, intuitive cooling and flexible transfer options.
PCI-E 3.0 M.2 (Up to 32GB/s)
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
