Built for Ryzen 5000 Performance
The 5+3 phase VRM design provides stable power delivery to AMD Ryzen 5000 CPUs, enabling consistent performance during demanding workloads. With support for up to 4733MHz DDR4 memory (overclocked), you can maximise bandwidth for gaming, content creation, or multitasking. The B550 chipset supports PCIe 4.0 for the primary M.2 slot, ensuring your NVMe SSD operates at peak speeds for faster boot times and application loading.
Versatile Storage and Expansion
This motherboard offers six total storage options with two M.2 slots and four SATA III ports. The PCIe 4.0 M.2 slot supports the latest high-speed SSDs, while the secondary M.2 slot uses PCIe 3.0 for additional storage flexibility. RAID 0, 1, and 10 configurations are supported, allowing you to optimise for speed, redundancy, or a balance of both. Whether you’re building a gaming system or a workstation, the storage options accommodate both HDD and SSD configurations.
Comprehensive Connectivity Suite
Stay connected with dual-band Wi-Fi 5 and Bluetooth 5.0, providing wireless flexibility for peripherals and internet access. The Gigabit Ethernet port ensures reliable wired connectivity for gaming and streaming. Front panel USB 3.2 Gen 1 ports offer fast data transfer speeds, while the included antenna supports the wireless capabilities. The Realtek ALC1220-VB audio chip delivers 7.1 channel surround sound for immersive gaming and entertainment experiences.
Compact Micro ATX Design
The micro ATX form factor (244mm x 244mm) fits in smaller cases without sacrificing essential features. This makes it perfect for space-conscious builds where you need performance but want to maintain a smaller footprint. The passive cooling design reduces noise while maintaining optimal temperatures, and the dark brown PCB provides a professional appearance that complements most build themes.
