Asus Prime B850M-K-CSM M-ATX Motherboard

Features:

ASUS Prime series motherboards are expertly engineered to unleash the full potential of AMD Ryzen 9000 series processors. The PRIME B850M-K-CSM motherboard provides users and PC DIY builders with a range of performance optimizations via intuitive software and firmware features. It’s designed to be Advanced AI PC-ready, offering the power and connectivity needed for demanding AI applications.

Digital Power Design

PRIME B850M-K-CSM 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.

Enhanced DDR5 performance

Comprehensive memory tuning options are the cornerstone of PRIME motherboards. The PRIME B850M-K-CSM maximizes 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 optimized profiles for enhanced performance.

For those looking to surpass stock DDR5 speeds, the PRIME B850M-K-CSM 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-CSM 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-CSM 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.

VRM heatsink and thermal pad

One massive VRM heatsink and essential thermal pad improve heat transfer from the MOSFETs and chokes for better cooling performance.

Multiple temperature sources

Each header can dynamically reference three thermal sensors. Fan Xpert 2+ lets you to map the temperature of supported ASUS graphics cards to optimize cooling for GPU- and CPU-intensive tasks.

4-Pin PWM/DC fan

Each onboard header supports auto-detection of PWM or DC fans.

M.2 heatsink

The M.2 heatsink takes care of the M.2 slot, preventing throttling that can occur with M.2 storage during extended transfers.

Passive chipset heatsink

An aluminum passive chipset heatsink ensures optimal cooling and stable performance. It is more durable and longer-lasting than heatsinks with fans, which can be vulnerable to the buildup of dust and debris.

Smart protection

A dedicated integrated circuit protects each fan header from overheating and excess current.

Realtek 2.5 Gb 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.

Build for the most advanced pc for gaming and creating

When only the fastest will do, ASUS motherboards deliver. With faster dual-channel DDR5 memory support, AMD EXPO technology and PCIe 5.0 support for both graphics and NVMe, you can play the most demanding games and deliver your biggest projects with the revolutionary performance of an ASUS motherboard and AMD Ryzen 9000, 8000, and 7000 Series processors.
