Maxsun iCraft B860M Cross Pro specifications and in-depth review

Maxsun iCraft B860M Cross Pro

Manufacturer: Maxsun

The Maxsun iCraft B860M Cross Pro is a Micro-ATX motherboard built around Intel's LGA 1851 socket and B860 chipset, measuring 245 × 245 mm. It ships with Wi-Fi 7 (802.11be) and Bluetooth 5.4 integrated, along with RGB lighting, dual BIOS, and an easy BIOS reset button — a fairly well-rounded feature set for a board in this form factor. A three-year warranty is included.

Memory support runs up to 192 GB of DDR5 across four slots in a dual-channel configuration, with standard speeds reaching 6400 MHz and overclocked profiles going as high as 9066 MHz. Expansion is handled by one PCIe 5.0 x16 slot and one PCIe x4 slot, while storage connectivity includes three M.2 sockets and four SATA 3 connectors. The rear I/O provides eight USB 3.2 Gen 2 Type-A ports, one USB 4 40 Gbps port, one Thunderbolt 4 port, HDMI 2.0, one DisplayPort output, and a single RJ45 Ethernet jack, complemented by five audio connectors and an S/PDIF output.

Pros
  • Supports Wi-Fi 7 alongside the full range from Wi-Fi 4 through Wi-Fi 6E, covering a broad span of wireless standards
  • Thunderbolt 4 and USB 4 40 Gbps ports are available on a B860 Micro-ATX board, which is uncommon at this form factor
  • Eight USB 3.2 Gen 2 Type-A ports on the rear I/O provides an unusually high count for rear-panel connectivity
  • DDR5 memory can be overclocked up to 9066 MHz across four slots with a 192 GB ceiling, offering substantial headroom for memory-intensive workloads
  • Dual BIOS and an easy BIOS reset button reduce the risk of a failed firmware update causing permanent board issues
  • Three M.2 sockets combined with four SATA 3 connectors give a reasonable number of storage attachment points for a Micro-ATX layout
Cons
  • No PCIe 4.0 or 3.0 x16 slots beyond the single PCIe 5.0 slot limits multi-card or legacy expansion options
  • ECC memory is not supported, ruling out use cases that require error-correcting RAM
  • There is no TPM connector, which may be a limitation for certain security or enterprise configurations
  • Only one RJ45 port is present, with no provision for multi-port or redundant wired networking
  • No USB-C ports on the rear I/O panel beyond the USB 4 and Thunderbolt 4 connections, and no lower-speed USB 3.2 Gen 1 or USB 2.0 rear ports
Who is this for?

This board is a solid fit for users building a capable desktop system in a compact footprint who still want modern connectivity without compromise. The combination of Wi-Fi 7, Thunderbolt 4, and a high USB 3.2 Gen 2 port count makes it well suited for content creators or power users who rely on fast peripheral throughput and wireless flexibility. Those looking to push memory performance will also find value here, as the support for DDR5 overclocking up to 9066 MHz across four slots gives enthusiast-level headroom within a Micro-ATX chassis. The dual BIOS and easy reset features additionally make it practical for users who frequently update firmware or experiment with system configuration.

Who is this NOT for?

Users who need ECC memory support for workstation-grade reliability or data-integrity-sensitive tasks will find this board unsuitable, as that capability is absent. It is equally a poor match for those requiring multi-card PCIe expansion, since only a single x16 slot is present alongside one x4 slot, leaving no room for complex multi-GPU or high-bandwidth add-in card setups. Additionally, system builders who depend on a TPM connector for hardware-level security configurations will need to look elsewhere, as no such header is provided on this board.
