Description
The ASUS Prime series is expertly designed to unleash the full potential of the AMD Ryzen platform. Featuring a robust power design, comprehensive cooling solutions, and smart optimization options, the Prime B550 series motherboards offer everyday users and DIY PC builders a range of performance optimization options via intuitive software and firmware features.
High flexibility The comprehensive control system forms the basis of the ASUS Prime series. The Prime B550 motherboard contains flexible tools to optimize every aspect of your system, enabling performance adjustments to perfectly fit the way you work and maximize productivity.
Comprehensive power efficiency The Energy Processing Unit (EPU) saves power at the system level. The EPU automatically optimizes power consumption and maximizes savings with Away mode.
Effective Cooling The PRIME B550 series is designed with a series of hybrid fan headers to ensure the cooling and stability of your system even under heavy workloads.
Multiple temperature sources Each header can dynamically reference three thermal sensors. Through Fan Xpert 2+ you can map the temperature of supported ASUS graphics cards to optimize cooling for GPU and CPU tasks.
Excellent performance The PRIME B550 motherboard offers all the essentials to boost daily productivity: your system will be ready for action with stable power supply, intuitive cooling, and flexible data transfer options.
Built-in integrated features offer high audio The cleverly thought-out design together with the advanced hardware offer audio quality unlike any other motherboard you've ever experienced.
Audio shielding Ensures analog/digital accuracy and remarkable reduction of multi-lateral interference.
Dedicated audio layers on the PCB Separate layers for left and right tracks ensures both channels are of equal quality.
