ASUS PRIME B860M-A WIFI micro ATX motherboard - Intel B860 LGA 1851
Built to last
The ASUS Prime B860M-A is engineered to unleash the capabilities of Intel Core Ultra Series 2 processors with a strong power setup, advanced cooling, and user-friendly tuning options. Fitted with two M.2 slots, it offers ample room for high-speed storage, while PCIe® 5.0 x16 support gears it for next-gen graphics. Built for the future, it provides a combination of legacy and modern USB connections, ideal for gaming setups. With intuitive software and firmware, it’s crafted for PC builders aiming for high and reliable performance.
Robust Architecture
Stable power delivery is the backbone of high-performance computing, especially for Intel Core Ultra Series 2 processors. This design integrates high-side and low-side MOSFETs with dedicated drivers into equally rated (80A) power stages, reducing electrical resistance and minimising switching losses. The result is precise voltage regulation, enhanced thermal efficiency, and sustained stability, ensuring that both current and next-gen Intel processors perform at their best when challenged most.
DDR5 Domination
ASUS Enhanced Memory Profile (AEMP) automatically detects memory chips and provides optimised profiles for enhanced performance. For those looking to surpass stock DDR5 speeds, the B860M-A offers extensive AMD Extended Profiles for Overclocking (EXPO™) support and a wide array of UEFI settings for further performance tweaks.
Loaded With M.2 Slots
B860M-A offers two M.2 slots, one which supports 128Gbps via PCIe 5.0, and another which channels 64Gbps via PCIe 4.0. This enables quicker boot-up and app load times with OS or application drives.
Link Up With Ease
This motherboard offers extensive connectivity, with a well-organised layout that makes linking all your components a breeze. The stylish backplate not only adds a sleek touch but also reinforces the build for added stability. With its intuitive design, it’s perfect for beginners looking to dive into PC building, offering a user-friendly experience without compromising on quality or capability.
