AI-Ready Intel Platform
The ASUS PRIME B860-PLUS WIFI is an ATX motherboard built for Intel Core Ultra Series 2 processors on the LGA 1851 socket. It targets builders who want a modern AI PC foundation with high-speed connectivity and generous expansion options. Four DDR5 slots support up to 192GB of memory running at 8200 MT/s overclocked speeds.
Sustained Power Delivery
An 8+1+1+1 phase design uses 80A DrMOS power stages fed by an 8-pin ProCool connector, alloy chokes and durable capacitors. This topology keeps voltage stable during long rendering, compilation or AI inference sessions without the throttling seen on lighter phase counts. Dual-channel architecture and XMP support maintain memory throughput under continuous load.
Thermal Management and Power Draw
Enlarged VRM heatsinks, a dedicated M.2 heatsink and a PCH heatsink dissipate heat across the board. Hybrid fan headers controlled by Fan Xpert 2+ adjust speeds based on system temperatures, keeping noise low during typical workloads. The 2.5Gb Ethernet and WiFi 6E controllers add minimal power draw while providing high-throughput networking.

Questions sur cet article
How much heat does the 8+1+1+1 80A DrMOS power design generate under sustained load?
The enlarged VRM heatsinks, PCH heatsink and hybrid fan headers managed by Fan Xpert 2+ are designed to dissipate heat from the 80A DrMOS stages during all-day operation.
Which DDR5 memory kit do I need to reach the 8200 MT/s overclocked speed?
You need a non-ECC unbuffered DDR5 CUDIMM kit rated for 8200 MT/s or higher with XMP or ASUS Enhanced Memory Profile II support, installed in all four 288-pin slots for dual-channel operation.
Will my existing PCIe 4.0 graphics card run at full x16 speed in the top slot?
The primary PCIe 5.0 x16 slot is wired to the Intel Core Ultra Series 2 processor and will operate your PCIe 4.0 graphics card at x16 electrical speed.
