AI Advisor - ASUS AI Advisor allows users to explore the functionality and advanced features of ASUS motherboards in a simple and straightforward way.
Digital Power Design - PRIME B850M-K features an 8+2+1 phase power design with discrete MOSFETs, ensuring efficient and stable power delivery for AMD processors plus steady performance for day-to-day use.
Six-layer PCB design - The multi-layered printed circuit board design quickly dissipates heat around the voltage regulators to improve overall system stability and provide the CPU with more overclocking headroom.
Digi+ VRM control - The Digi+ voltage-regulator module (VRM) delivers real-time control over voltage droop, automatically switching frequency and power-efficiency settings.
Enhanced Memory & Storage Performance
Enhanced DDR5 performance - Comprehensive memory tuning options are the cornerstone of PRIME motherboards. The PRIME B850M-K maximises the potential of your DDR5 modules, from entry-level to extreme-speed kits. For entry-level modules without EXPO™ support, ASUS Enhanced Memory Profile (AEMP) automatically detects memory chips and provides optimised 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 128Gbps) - 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.
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.
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.
Realtek 2.5Gb Ethernet - Realtek 2.5 Gb Ethernet reduces CPU overhead and offers exceptionally high TCP and UDP throughput for faster, smoother data transfers.
High Speed Transferring - Numerous USB ports support high-end rigs loaded with peripherals, including two rear USB Type-A ports with transmission speeds of up to 10Gbps and a front USB Type-C® connector with ultrafast USB 5Gbps for transmission speeds of up to 5Gbps.
Personalization
The PRIME B850M-K enhances the user experience across the board, from simplifying BIOS setting adjustments to offering customizable RGB lighting controls for a uniquely personal system aesthetic.
UEFI BIOS- The UEFI interface delivers easy-to-use configuration options for PC beginners, and advanced features for veterans.
ASUS DriverHub- Simplify driver management with automatic detection, one-click installation and update for smooth, efficient system performance.
Armoury Crate- customise Aura Sync RGB and control ASUS devices. Includes product registration and updates.
Aura Sync- Complete RGB lighting control for enthusiast systems, ensuring seamless synchronization with compatible hardware.
Addressable Gen2 RGB headers - Three Addressable RGB Gen 2 headers detect LED counts on compatible RGB devices, automatically adjusting lighting effects accordingly.
DIY friendly
The PRIME B850M-K motherboard features EZ PC DIY innovations that simplify and speed up the PC building process, making DIY easy and convenient.
BIOS FlashBack - BIOS FlashBack™ simplifies BIOS updates. Just load the BIOS file onto a FAT32 USB stick, insert it into the BIOS FlashBack™ port, and press a button—no CPU or memory needed.
SafeSlot - PCIe 5.0 is twice as fast as PCIe 4.0. ASUS has adapted our SMT manufacturing for the faster SafeSlot, a reinforced metal sheath that ensures secure card installation and faster data speeds.
Q-LED Core - The Q-LED Core display produces colour-coded lights during the Power-On Self-Test (POST) that can help you troubleshoot potential issues.
