Enhanced Memory & Storage Performance

Enhanced DDR5 performance

Comprehensive memory tuning options are the cornerstone of PRIME motherboards. The PRIME B850M-K maximizes the potential of your DDR5 modules, from entry-level to extreme-speed kits.²

For entry-level modules without EXPO^™ support, ASUS Enhanced Memory Profile (AEMP) automatically detects memory chips and provides optimized profiles for enhanced performance.

For those looking to surpass stock DDR5 speeds, the PRIME B850M-K offers extensive AMD Extended Profiles for Overclocking (EXPO^™) support and a wide array of UEFI settings for further performance tweaks.

Two M.2 slots (up to 128 Gbps)

PRIME B850M-K offers a total of two M.2 slots, including one that supports data-transfer speeds of up to 128 Gbps via PCIe 5.0, and one that support PCIe 4.0. This enables quicker boot-up and app load times with OS or application drives.

Cooling

Cooler by design

The PRIME B850M-K motherboard is engineered with multiple onboard heatsinks and an array of hybrid fan headers to help ensure your rig stays cool and stable under intense workloads.

ASUS Fan Xpert 2+

ASUS Fan Xpert 2+ software provides comprehensive control over fans. An 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.

Flexibility

Empowering connections

This motherboard offers a versatile range of connectivity, including support for PCIe 5.0 slot and an arsenal of USB ports which includes Type-C^® connection.
