90-MXBS4-A0UAYZ

High-Performance Micro-ATX Motherboard Platform for Intel Core Ultra Deployments with the 90-MXBS4-A0UAYZ

The 90-MXBS4-A0UAYZ is a Micro-ATX motherboard built on the Intel H810 chipset for the LGA1851 Intel Core Ultra platform, enabling compact workstation and office systems where platform stability, predictable I/O, and integrated graphics support are required. Its dual-channel DDR5 memory design with 2 DIMM slots targets right-sized capacity planning for endpoint and edge roles, prioritising low-latency responsiveness over maximum slot density.

For expansion and device attachment, 90-MXBS4-A0UAYZ provides PCIe 4.0 connectivity for both a full-height, full-length x16 slot and an additional PCIe 4.0 x1 slot, supporting GPU acceleration where needed and add-in controllers such as NICs or capture cards. Storage architecture balances NVMe performance and SATA scalability with a PCIe 4.0 M.2 2280 (M-Key) slot for OS and hot datasets, plus 4 SATA 6Gb/s ports for bulk or mirrored storage at the software layer. A dedicated M.2 2230 (E-Key) slot enables Wi‑Fi module integration without consuming PCIe slots, and AMI UEFI firmware supports consistent provisioning workflows in managed fleets.

Why Choose the 90-MXBS4-A0UAYZ?

The 90-MXBS4-A0UAYZ delivers a pragmatic density-to-performance profile for SMB edge nodes and compact lab systems, combining PCIe 4.0 expansion with 2.5GbE networking in a space-efficient form factor. This makes 90-MXBS4-A0UAYZ well-suited to repeatable deployments where component interoperability, straightforward servicing, and controlled platform scope are more important than enthusiast features such as chipset RAID.

ASRock engineering focuses on reliable mainstream platforms with clear lifecycle alignment, robust firmware foundations, and standards-based integration for modern data centre and enterprise edge environments, supporting consistent build quality across volume rollouts.

Key Applications:

Entry workstation and office desktops
SMB edge routing and firewall appliances with add-in NIC
Lab and dev OS validation systems
Light virtualization and container hosts
General productivity and light content creation

At Happyware - Server Hardware you benefit from non-binding offers tailored to your deployment plan for the 90-MXBS4-A0UAYZ and the option to extend warranty coverage up to 6 years to protect long-lived workplace and edge installations.
