Description

Description

The Asus Prime B650M-K motherboard is aimed at users who need a reliable and straightforward solution for assembling a new computer with AMD Ryzen 7000 series processors. The board features PCIe 4.0 slots for fast storage devices and graphics cards, as well as USB 3.2 Gen 2 ports for fast data transfer.

Additionally, it features ASUS OptiMem II technology for improved memory stability and support for various ASUS technologies for enhanced performance and easier computer management.

Flexible air and liquid cooling controls

The ASUS Fan Xpert 2+ software provides comprehensive control over fans and all-in-one (AiO) coolers. Whether cooling with air or water, an auto-tuning mode intelligently configures all parameters with a single click. There is also an Extreme Quiet mode that reduces chassis fan speeds below the default minimum threshold, making your system whisper-quiet when performing light tasks. Fans and AiO coolers can also be controlled via the UEFI BIOS.

Enhance CPU Performance

The AMD Precision Boost Overdrive (PBO) function increases the control of the CPU's current and voltage to opportunistically boost performance. With aggressive PBO parameter tuning, AMD's algorithm can leverage the motherboard's robust power solution to enhance performance even further.

Energy efficiency everywhere

The power-saving function includes various settings that can easily optimize power consumption and maximize energy savings. You can enable a CPU power limit, turn off Aura lighting, and set the fan profile to power-saving mode. You can also enable the power-saving plan built into Microsoft Windows.

M.2 Heatsink

The M.2 heatsink prevents throttling that can occur with M.2 storage during continuous transfers. The heatsink is held in place with captive screws, and these removable screws help reduce the risk of dropping or losing them when removing the heatsink.

VRM Heatsink and Thermal Pads

The VRM heatsink and thermal pads improve heat transfer from the MOSFETs and chokes for better cooling performance.

DDR5 Performance Enhancement

Comprehensive memory tuning options are the cornerstone of PRIME motherboards. With the PRIME B650M-K, you can harness the full potential of DDR5 modules, whether it's an extreme speed kit or an entry-level set that would otherwise be locked.

ASUS OptiMem II

The revisions in motherboard routing provide the latest processors with unrestricted access to memory bandwidth. The ASUS OptiMem II technology carefully maps memory signal paths across different layers of the PCB to reduce vias and adds shielding zones that significantly reduce crosstalk.

Advantages of ASUS OptiMem II technology:

  • Improved memory stability and compatibility
  • Allows lower memory latencies at equivalent voltages
  • Enhanced memory frequency margin

Storage

Support for PCIe 5.0 M.2

The PRIME B650M-K offers a total of two M.2 slots, the first supporting data transfer speeds of up to 128Gbps via PCIe 5.0, allowing for faster boot and application load times with operating system or application drives.

PCIe 4.0 Slot

Prime B650 motherboards offer PCIe 4.0 Slot connectivity for the latest GPUs. The large bandwidth and ultra-fast transmission speeds allow you to create feature-rich builds that can handle heavy workloads effortlessly.

Front USB Type-C®

A comprehensive array of USB ports supporting high-spec equipment loaded with peripherals, including a front-panel USB 3.2 Gen 1 Type-C® connector that provides data transfer speeds of up to 5Gbps.
