Quick and Simple Setup EZ mode displays vital settings and stats and also offers guided wizards, drag-and-drop functionality, and one-click application of important settings — all to help you get your rig up and running in no time. Cool to the Core Prime B450M II series 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 Pads A VRM heatsink with underneath thermal pad improves heat transfer from the MOSFETs for better cooling performance. Cooler by Design Prime B450M-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. Build on a Solid Foundation Prime B450M II 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. PCIe 3.0 M.2 (up to 32 Gbps) Achieve speed with onboard M.2 M.2 Slot supports up to 22110 and data-transfer speed up to 32Gbps 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 2 Type-A Numerous USB ports support high-end rigs loaded with peripherals, including two rear-panel USB Type-A connectors with fast USB 3.2 Gen 2 connectivity for compatible cases. Little Things Make a Big Difference Prime B450M II series adds the nuanced details that improve every experience, from exclusive codecs that provide pristine audio quality to intuitive RGB lighting controls 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. 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. SafeSlot Core Fortified PCIe slot prevents damage 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 World-class circuit-protecting power design 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 Short-circuit damage prevention 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 3X corrosion-resistance for greater durability Corrosion-resistant stainless-steel back I/O panels bonded with chromium oxide have a lifespan that's three times longer than ordinary panels. LANGuard Pumped-up throughput 2.5X higher surge tolerance 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.
