Maxsun eSport B850ITX WiFi Ice

Manufacturer: Maxsun

The Maxsun eSport B850ITX WiFi Ice is a Mini-ITX motherboard built around the AM5 socket and B850 chipset, making it a compact option for systems based on compatible AMD processors. It features built-in Wi-Fi 6 (802.11ax) alongside Bluetooth 5.2, and includes RGB lighting, dual BIOS, and an easy BIOS reset mechanism. The board carries a 3-year warranty and measures 170 mm × 170 mm.

Memory support reaches up to 96 GB of DDR5 across two slots in a dual-channel configuration, with a standard maximum speed of 5200 MHz and overclocked profiles extending to 8000 MHz. Storage connectivity includes two M.2 sockets and two SATA 3 connectors. The single expansion slot runs at PCIe 5.0 x16, and rear I/O provides two USB 3.2 Gen 1 Type-A ports, four USB 2.0 ports, one HDMI 1.4 output, one DisplayPort, and a single RJ45 Ethernet port. Three fan headers and a TPM connector round out the internal connections.

Pros
  • Supports Wi-Fi 6 (802.11ax) along with older 802.11n and 802.11ac standards, providing flexible wireless connectivity
  • Dual BIOS and a clear CMOS button add a layer of reliability and ease of recovery when overclocking or experimenting with BIOS settings
  • DDR5 memory with overclocked speeds up to 8000 MHz offers substantial headroom for high-performance memory configurations
  • The single PCIe 5.0 x16 slot delivers the latest generation of expansion bandwidth for graphics or other add-in cards
  • A 3-year warranty provides extended coverage for a compact motherboard
  • RGB lighting and an easy overclock feature make the board accessible for users who want visual customization and simplified tuning
Cons
  • Only two memory slots limits upgrade flexibility and the ability to run four-stick configurations
  • No USB Type-C ports on the rear I/O restricts connectivity for modern peripherals and devices
  • Limited to two SATA 3 connectors, which may be insufficient for builds requiring multiple storage drives
  • With only three fan headers, thermal management options are somewhat constrained for more demanding cooling setups
  • No S/PDIF digital audio output may be a drawback for users with digital audio equipment
  • RAID 0+1 is not supported, limiting storage redundancy options for users who need it
Who is this for?

This board is well-suited for builders putting together a compact Mini-ITX system based on AMD's AM5 platform, particularly those who want modern connectivity without sacrificing space. The inclusion of Wi-Fi 6, Bluetooth 5.2, and a PCIe 5.0 x16 slot makes it a practical choice for small form factor gaming or productivity builds that still demand up-to-date hardware support. Users who value reliability features such as dual BIOS and easy BIOS reset will also find it accommodating, especially when pushing DDR5 memory with overclocked speeds up to 8000 MHz.

Who is this NOT for?

This board is not a good fit for users who need extensive storage expansion, as the two SATA 3 connectors and two M.2 sockets offer limited room for multi-drive configurations, and RAID 0+1 is unsupported. Builders looking for a rich rear USB selection — including USB Type-C, USB 3.2 Gen 2, or higher-speed USB 4 ports — will find the I/O lacking for modern peripheral-heavy setups. It is also unsuitable for workstation users who require ECC memory support or those needing more than three fan headers for complex custom cooling arrangements.
