Maxsun iCraft B860M Cross specifications and in-depth review

Maxsun iCraft B860M Cross

Manufacturer: Maxsun

The Maxsun iCraft B860M Cross is a Micro-ATX motherboard designed around Intel's LGA 1851 platform and B860 chipset, measuring 245 mm × 245 mm. It ships with a three-year warranty and includes quality-of-life features such as RGB lighting, a clear CMOS button, and dual BIOS for straightforward recovery. Wireless connectivity is handled by an integrated adapter covering Wi-Fi 4 through Wi-Fi 6E alongside Bluetooth 5.3.

Memory support reaches up to 192 GB of DDR5 across four slots in a dual-channel configuration, with standard speeds up to 6400 MHz and overclocked profiles extending to 9066 MHz. Expansion is anchored by a single PCIe 5.0 x16 slot and a PCIe x4 slot, while three M.2 sockets and four SATA 3 connectors cover storage needs. 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, a DisplayPort output, and a single RJ45 jack, with five audio connectors and S/PDIF out rounding out the panel.

Pros
  • Dual BIOS provides a built-in recovery option if one BIOS becomes corrupted
  • Four DDR5 slots support up to 192 GB of RAM with overclocked speeds reaching 9066 MHz
  • A single PCIe 5.0 x16 slot ensures compatibility with the latest discrete graphics cards
  • Eight USB 3.2 Gen 2 Type-A ports on the rear panel offer fast and plentiful connectivity
  • Wi-Fi 6E and Bluetooth 5.3 are built in, removing the need for separate wireless adapters
  • Three M.2 sockets alongside four SATA 3 connectors provide flexible storage expansion
Cons
  • Micro-ATX form factor limits the total number of expansion slots compared to full-size boards
  • No PCIe x1 slots are available, restricting the addition of compact expansion cards
  • ECC memory is not supported, making the board unsuitable for workloads that require error-correcting RAM
  • There is no TPM connector, which may complicate hardware-based security configurations
  • RAID 0+1 storage configurations are not supported
Who is this for?

This board suits builders looking to assemble a capable desktop system on the Intel LGA 1851 platform within a compact footprint. Its three M.2 sockets, four SATA 3 connectors, and PCIe 5.0 x16 slot make it a practical choice for users who want modern storage flexibility and support for the latest discrete graphics. The built-in Wi-Fi 6E and Bluetooth 5.3 appeal to those setting up in spaces where running Ethernet is inconvenient, while the dual BIOS and DDR5 support up to 192 GB with overclocked speeds reaching 9066 MHz will suit enthusiasts who want headroom for memory tuning without sacrificing system stability.

Who is this NOT for?

Users who need a high slot count for multiple expansion cards will find the Micro-ATX layout restrictive, as there are no PCIe x1 slots and only a single secondary PCIe x4 slot available. The board is also a poor fit for workstation or server-oriented builds that rely on ECC memory for data integrity or require RAID 0+1 configurations for storage redundancy. Similarly, anyone needing a TPM connector for hardware-based security compliance — such as in managed enterprise environments — will find the lack of that header a notable limitation.
