FLEXIBILITY

Comprehensive controls form the foundation of the ASUS PRIME series. The PRIME B550 motherboard packs flexible tools to tune every aspect of your system, enabling performance tweaks to perfectly match the way you work to maximize productivity.

All-Around Energy Efficiency

With the Energy Processing Unit (EPU), you‘ll enjoy system-wide power savings.The EPU automatically optimizes power consumption and maximizes savings with Away mode.

COOLING

PRIME B550 series are engineered with an array of hybrid fan headers to ensure your rig stays cool and stable under intense workloads.

Cooler by Design

PRIME B550 series feature comprehensive cooling controls that are configurable via Fan Xpert 2+ software or via the UEFI BIOS.

Multiple Temperature Sources

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

PERFORMANCE

PRIME B550 motherboard provides all the fundamentals to boost daily productivity, so your system will be ready for action with stable power, intuitive cooling and flexible data transfer options.

Dual M.2 Slots (up to 64 Gbps)

PRIME B550M-K ARGB offers a total of two M.2 slots, one of which supports data-transfer speeds of up to 64Gbps via PCIe 4.0, enabling quicker boot-up and app load times with OS or application drives.
