VRM Heatsink and Thermal Pads
A VRM heatsink with an 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.
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.
BIOS FLASHBACK
BIOS FlashBack is the simplest and safest (UEFI) BIOS update method. Simply drop the (UEFI) BIOS file onto a FAT32 formatted USB stick, plug it into the USB BIOS FlashBack port and press the button. Updates can even be performed without having memory or a CPU installed.
SafeSlot Core
A 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.
