Power Saving: The Power Saving function contains several settings to easily optimize power consumption and maximize energy savings. You can enable a CPU power limit; darken Aura lighting and set the fan profile to a Power Saving mode. You can also toggle the Power Saver plan that is built into Microsoft Windows.
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 B840-PLUS WIFI 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 B840-PLUS WIFI offers extensive AMD Extended Profiles for Overclocking (EXPO) support and a wide array of UEFI settings for further performance tweaks.
Three M.2 slots (up to 64 Gbps): PRIME B840-PLUS WIFI offers a total of three M.2 slots; including two that support data-transfer speeds of up to 64 Gbps via PCIe 4.0; and one that supports PCIe 3.0. This enables quicker boot-up and app load times with OS or application drives.
Cooling
Cooler by design: The PRIME B840-PLUS WIFI 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.
Cooler by design - VRM heatsink and thermal pads: Two massive VRM heatsinks and essential thermal pads improve heat transfer from the MOSFETs and chokes for better cooling performance.
Cooler by design - AIO pump header: A dedicated PWM/DC header supports self-contained water-cooling setups.
Cooler by design - 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.
Cooler by design - 4-Pin PWM/DC fan: Each onboard header supports auto-detection of PWM or DC fans.
Cooler by design - M.2 heatsink: One Flexible M.2 heatsink that can take care of either of the two M.2 slots; preventing throttling that can occur with M.2 storage during extended transfers.
Cooler by design - 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.
Cooler by design - Smart protection: A dedicated integrated circuit protects each fan header from overheating and excess current.
Smart Cooling precision - 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.
Smart Cooling precision - Cooler compatibility: ASUS AIO coolers offer robust performance; high overclocking potential; bold aesthetics and customizable functionality for new motherboards; empowering you to build your dream gaming rig.
