This makes the Prime B850-Plus WiFi a future-proof platform for current and next-generation graphics cards and NVMe SSDs. DDR5 Up to 8000 MHz — EXPO & XMP Support for DDR5 up to 8000 MHz with AMD EXPO and Intel XMP gives you maximum flexibility for memory overclocking. With up to 256GB maximum capacity across four DIMM slots, this board is ready for both gaming and memory-intensive workstation tasks. Wi-Fi 6E + 2.5GbE — Fast Wired & Wireless Wi-Fi 6E (802.11ax) with the dedicated 6GHz band delivers fast, low-latency wireless connectivity. Combined with 2.5 Gigabit Ethernet — 2.5× faster than standard 1GbE — you have the networking bandwidth needed for smooth online gaming and fast local transfers. BIOS FlashBack — Update Without CPU or RAM BIOS FlashBack allows you to update the BIOS using only a FAT32 USB drive and the board’s power connectors — no CPU, memory, or GPU required. Essential for preparing the board for a new CPU generation before the processor arrives. Thunderbolt Header + USB 10Gbps Type-C The Thunderbolt (USB4) header adds support for Thunderbolt peripherals via a compatible add-in card. A USB 10Gbps Type-C port on the rear I/O delivers fast external storage and device connectivity, providing the bandwidth demanded by advanced AI PC applications. ASUS AI Advisor ASUS AI Advisor is an AI-powered technical expert built into the platform, always available to answer hardware questions in natural language. From one-click optimization features like AI Overclocking and fan tuning for beginners, to detailed guidance on advanced features for veterans — it’s like having an expert on call. 3 M.2 Slots + 4 SATA — Expansive Storage Three M.2 slots (including one PCIe 5.0) combined with four SATA III ports support up to seven storage devices simultaneously, with RAID 0, 1, 5, and 10 support for both NVMe and SATA drives. Plenty of room for fast boot drives, game libraries, and mass storage.
