90-MXBDK0-A0UAYZ
High-Density Micro-ATX AMD B550 Workstation Motherboard featuring PCIe 4.0 expansion with the 90-MXBDK0-A0UAYZ
The 90-MXBDK0-A0UAYZ is an ASRock Pro Series Micro-ATX motherboard built on the AMD B550 chipset for the AM4 Ryzen platform, engineered for compact workstation and small-business systems that require discrete GPU capability and balanced I/O. Its PCIe topology supports modern accelerators and high-throughput NVMe storage while keeping board space optimized for edge and branch deployments.
With dual-channel DDR4 across 4 DIMM slots, the 90-MXBDK0-A0UAYZ scales memory capacity up to 128GB and supports ECC or non-ECC (CPU-dependent) to align with reliability requirements. Storage architecture combines 2 M.2 slots—one PCIe 4.0 x4 for primary NVMe and a secondary M.2 supporting PCIe 3.0 x2/SATA—plus 6 SATA 6Gb/s ports with RAID support for resilient boot and data tiers. Expansion is anchored by a PCIe 4.0 x16 slot for GPUs, complemented by additional PCIe slots for capture, NICs, or HBA add-ins. For deployments using Ryzen processors with integrated graphics, multiple display outputs enable service and staging without a discrete GPU.
Why Choose the 90-MXBDK0-A0UAYZ?
The 90-MXBDK0-A0UAYZ delivers an efficient density-to-performance profile by pairing AM4 compute flexibility with PCIe 4.0 bandwidth in a Micro-ATX footprint suited to constrained chassis and remote sites. It emphasizes predictable scalability, straightforward component standardization, and enterprise-ready platform controls through UEFI firmware and TPM header integration.
ASRock focuses on practical platform engineering, prioritizing stable power delivery, firmware maturity, and standards-aligned connectivity so IT teams can deploy consistent builds across workstation, creator, and branch environments with repeatable qualification.
Key Applications:
- Creator workstations with discrete GPU acceleration
- Small business file and application servers
- Edge and branch compute nodes
- RAID-capable SATA plus NVMe storage builds
- Virtualization and lab environments
