Prime B650M-K
ASUS Prime series motherboards are expertly designed
to unleash the full potential of AMD Ryzen 5 6400U processors
7000. With a robust power design, cooling solutions
comprehensive and intelligent adjustment options, PRIME B650M-K offers users
users and PC builders a range of optimizations
performance through intuitive software and firmware features.
Increase CPU performance
AMD Precision Boost Overdrive (PBO) increases the budget of
CPU current and voltage to increase performance in a way
opportunistic. By aggressively adjusting the PBO parameters, the algorithm
AMD can take advantage of the motherboard's robust power solution
to further increase performance.
Comprehensive energy efficiency
The power saving function contains several settings that
can easily optimize energy consumption and maximize savings
power. You can enable a CPU power limit, dim the
Aura lighting and set the fan profile to a mode
energy saving plan. You can also toggle the energy saving plan
power integrated into Microsoft Windows.
Flexible cooling controls
ASUS Fan Xpert 2+ software provides comprehensive control over
the fans. An automatic adjustment mode automatically configures
intelligently all parameters with one click. There is also a mode
Extreme Quiet which reduces the chassis fan speed by
below the default minimum to keep the system quiet at
perform light tasks. The fans can also be controlled via
via UEFI BIOS.
Precise digital power control
The Digi+ voltage regulator module (VRM) offers real-time control
real on voltage drop, automatically switching the
frequency and energy efficiency settings. It also
allows you to fine-tune your CPU for maximum stability and performance.
M.2 Heatsink
The M.2 heatsink prevents throttling that can occur with
M.2 storage during sustained transfers. The heatsink
heat is held in place by captive screws, and these
Removable captive screws help reduce the risk of falls or
losses during heat sink removal.
VRM Heatsink and Thermal Pads
The heatsink and VRM thermal pads improve the
heat transfer from the MOSFETs and shims for better
cooling performance.
DDR5 Performance Improvement
Comprehensive memory tuning options are the cornerstone of
PRIME motherboards. With PRIME B650M-K, you can extract all the
potential of your DDR5 modules, whether from an extreme speed kit or
from an otherwise locked core set.
Storage
PCIe 5.0 M.2 support
PRIME B650M-K offers a total of two M.2 slots, the first one supports
Data transfer rates of up to 128Gbps via PCIe
5.0, allowing for faster boot and application loading times
fast with operating systems or application units.
PCIe 4.0 slot
Prime B650 motherboards offer PCIe 4.0 slot connectivity
for the latest GPUs. The high bandwidth and speeds
Ultra-fast streaming capabilities allow you to create rich compilations
functions that can handle high loads effortlessly.
Front USB Type C®
A full complement of USB ports supports high-end equipment
loaded with peripherals, including a USB 3.2 Gen 1 Type-C® connector on
the front panel that provides data transfer speeds
up to 5 Gbps.
Realtek 2.5Gb Ethernet
Realtek 2.5Gb Ethernet reduces CPU overhead and delivers a
Exceptionally high TCP and UDP performance for data transfers
faster and smoother.
LANGuard
ASUS LANGuard is a hardware-level network protection feature
which integrates advanced signal coupling technology and
Premium anti-EMI surface mounted capacitors for improved
performance and ensure a more reliable connection.
ASUS OptiMem II
Motherboard Trace Routing Reviews
provide the latest processors with unrestricted access to the
memory bandwidth. ASUS OptiMem II technology maps
carefully routes memory signals through
different layers of PCB to reduce vias and add shielding areas
which significantly reduce crosstalk.
Exceptional audio
Combined integrated features deliver elevated audio
Audio shielding
Audio shielding ensures precise analog/digital separation and greatly reduced multilateral interference.
Dedicated audio PCB layers
Separate layers for left and right tracks ensure that both channels deliver consistent, even quality.
Premium audio capacitors
Delivers warm, natural, immersive sound with exceptional clarity and fidelity.
