MAXSUN Unveils MCIO ITX Motherboards for High-Bandwidth Compact Builds

MAXSUN introduced two new ITX motherboards that replace traditional expansion slots with a high-density MCIO interface. The MS-Challenger MCIO ITX and the MS-PC Farm B860I arrive as part of a broader shift toward compact, high-bandwidth connectivity standards. This move addresses the bandwidth limitations of standard PCIe slots in small form factor builds.

Two new boards replace standard slots with high-density MCIO connectors

The MS-Challenger MCIO ITX targets general enthusiasts and compact system builders. It utilizes Intel 800-series chipsets including Q870, Z890, H810, and B860. The board swaps out standard PCIe slots for MCIO connectors to accommodate modern graphics cards and storage devices.

Spec comparison

MCIO stands for Mini Cool Edge I/O and follows the SFF-TA-1016 specification. Each interface supports an x8 link width and handles PCIe Gen5 data rates with readiness for future Gen6 speeds. This configuration allows for higher data throughput in a smaller physical footprint than standard slots.

The MS-PC Farm B860I serves a different purpose by supporting PC cluster deployments. It features a transposed layout that enables the installation of four UDIMM memory sticks. The board also includes IPMI management capabilities, BIOS forced flashing, and smart fault diagnosis for remote maintenance.

We touched on Maxsun iCraft Z890 ITX Wi-Fi Motherboard in our earlier Maxsun coverage. That previous model highlighted active cooling solutions, while these new boards focus on interface density and management features. Both approaches reflect MAXSUN's strategy to diversify its ITX offerings.

MAXSUN confirmed the technical specifications for the MS-Challenger MCIO ITX and MS-PC Farm B860I. The products demonstrate how the MCIO standard can improve connectivity and management in small form factor PCs. No pricing or release dates are currently available for these motherboards.
