Enhance your business with an AMD Ryzen computer system using the ASUS PRIME B550M-A/CSM AM4 Micro-ATX Motherboard. Powered by the AMD B550 chipset, this motherboard supports third-generation AMD Ryzen processors with the AM4 socket. Designed to deliver enterprise-class performance in a small form factor, the micro-ATX motherboard takes advantage of the PCIe 4.0 s data bandwidth to deliver high performance for demanding tasks such as 3D rendering, video editing, and more. Up to 128GB of dual-channel DDR4 ECC memory, reaching 4400 MHz when overclocked, can be installed across four memory slots. The PRIME B550M-A also features advanced cooling and supports up to two M.2 SSDs and four SATA III storage drives, which can be put into RAID 0, 1, or 10 configurations. Its PCIe 4.0 x16 slot can accommodate a high-end graphics card and two PCIe 3.0 x1 slots are available for compatible expansion cards. Or you can use the AMD CPU s integrated graphics by connecting up to three monitors to the motherboard s HDMI, DVI-D, and VGA ports.
Connect peripherals such as keyboards and mice to the rear panel s USB 2.0 ports while reserving the USB 3.2 Gen 2 Type-A ports for transferring data from compatible devices at up to 10 Gb/s. Other features include a Gigabit Ethernet port, addressable Gen 2 Aura Sync RGB lighting headers, and a Realtek ALC887 7.1-channel audio system. Windows 10 64-bit is required to take advantage of all the motherboard s features.
High Performance Bandwidth
The ASUS PRIME B550M-A pairs third-generation AMD Ryzen AM4 processors and the high PCIe 4.0 memory bandwidth through the B550 chipset for maximum performance.
Enhanced Cooling
- VRM Heatsink: The Prime B550M-A features a large voltage-regulator module (VRM) heatsink with thermal pads to quickly transfer heat away from sensitive components. A fan holder is included for additional cooling.
- Active Chipset Heatsink: A heatsink and fan combination that helps to cool the chipset and avoid speed throttling during sustained data transfers.
- Hybrid Fan Headers: The motherboard can automatically detect the connected fans and liquid cooling pumps in PWM or voltage mode.
Storage and Memory
- Two M.2 slots support up to type 22110 NVMe PCIe and SATA SSDs.
- Four SATA III connectors are available for hard drives and 2.5" SSDs.
- Supports RAID 0, 1, and 10.
- Up to 128GB of dual-channel ECC DDR4 4400 (OC) memory can be installed across four slots.
Enhanced Memory Performance
ASUS OptiMem trace layout technology allows memory kits to operate and high frequencies and low voltages to maximize performance.
Power & Performance
The PRIME B550M-A has 8+1 DrMOS power stages that feature high-quality alloy chokes and durable capacitors to provide reliable power critical components such as the CPU.
High-Speed Connectivity
USB 3.2 Gen 2 Type-A ports transfer data at up to 10 Gb/s with compatible devices.
Audio Features
- Realtek ALC887 7.1-Channel HD Audio.
- Supports 24-bit / 192 kHz playback.
- Enhanced audio shielding
- Automatic jack detection and multi-streaming.
- LED illuminated audio trace path design.
Integrated Graphics
Take advantage of third-generation AMD Ryzen CPUs that have integrated graphics by connecting monitors to the motherboard s HDMI, DVI-D, and VGA ports.
Aura Sync RGB Lighting
Aura Sync technology allows you to connect, customize, and control lighting equipment such as RGB LEDs and light strips on the onboard RGB headers. You can choose from a variety of lighting presets that include Static, Strobing, and Color Cycle. These presets can be synchronized with Aura-capable peripherals such as keyboards, mice, monitors, and more. The addressable Gen 2 RGB headers can detect the number of LEDs on a compatible device to further tailor the lighting effects.
