90-MXBQR0-A0UAYZ

Compact Mini-ITX AM5 Motherboard architecture for SFF edge and workstation builds with the 90-MXBQR0-A0UAYZ

The 90-MXBQR0-A0UAYZ is a Mini-ITX motherboard built on the AMD B850 chipset for the AM5 Ryzen platform, targeting dense SFF systems where predictable PCIe lanes, NVMe throughput, and stable DDR5 behavior are more critical than sheer board real estate. It is engineered to support modern Ryzen CPU generations while keeping signal integrity and thermals under control in compact enclosures.

For memory, the 90-MXBQR0-A0UAYZ implements dual-channel DDR5 across 2 DIMM slots with support for ECC and non-ECC modules, enabling either cost-efficient client builds or more resilient edge deployments. Expansion is centered on a full-height PCIe 5.0 x16 slot for a single discrete GPU or high-bandwidth accelerator, while storage is optimized for NVMe-first designs via an M.2 2280 PCIe Gen5 slot for primary boot/applications plus an additional M.2 2280 PCIe Gen4 slot for tiered data or scratch. 2 SATA III ports remain available for legacy SSD/HDD requirements. Connectivity aligns with mixed wired/wireless environments through 2.5GbE and Wi‑Fi 6E with external antenna connectors, plus Bluetooth 5.2; display paths are available via HDMI 2.1 and USB-C video output when using a Ryzen CPU with iGPU.

Why Choose the 90-MXBQR0-A0UAYZ?

The 90-MXBQR0-A0UAYZ delivers a strong density-to-performance profile by combining PCIe Gen5 GPU readiness with NVMe-centric storage lanes in a Mini-ITX footprint, allowing scalable standardization across edge nodes, lab workstations, and compact compute appliances. RAID support and a mature UEFI with USB BIOS Flashback simplify lifecycle operations where no IPMI/BMC is required.

ASRock focuses on stable power delivery, firmware maturity, and pragmatic I/O layouts to meet modern data centre and enterprise lab expectations, enabling consistent builds, controlled updates, and dependable operation in always-on environments.

Key Applications:

SFF edge compute nodes
Compact single-GPU workstations
NVMe-centric build-and-test platforms
Virtualization and container labs
Industrial control and telemetry gateways

At Happyware - Server Hardware you benefit from non-binding offers tailored to your 90-MXBQR0-A0UAYZ deployment plan and an extended warranty of up to 6 years to protect long-lifecycle SFF and edge rollouts.
