Motherboard ASRock B860M PRO-A LGA1851

ASRock B860M PRO-A is a micro ATX motherboard with LGA 1851 socket and Intel B860 chipset, aimed at a stable mid-range build with the new generation of Intel Core Ultra processors. It combines support for DDR5 memory with high overclocking potential and serious storage options through PCIe Gen5 and Gen4 M.2 slots. The Micro ATX form factor allows you to build a more compact machine without sacrificing expandability. It is suitable if you are looking for a balance between modern interfaces and practical price/functionality.

What you get
With the LGA1851 socket and support for Intel Core Ultra processors, you have a foundation for a current platform with good longevity ahead. The four DDR5 slots with a capacity of up to 256 GB and frequencies up to 8666+MT/s (OC) provide you with space for serious multitasking, heavy applications, and future upgrades without changing the motherboard. For storage, you have one Blazing M.2 PCIe Gen5x4 slot directly to the CPU for the fastest NVMe SSDs and two more PCIe Gen4x4 M.2 slots for high-speed drives. The four SATA 6Gb/s ports plus RAID 0/1/5/10 support allow you to combine large capacity with redundancy or higher speed, depending on your needs. The built-in 2.5G LAN card provides higher network bandwidth compared to standard gigabit, which is a plus for online gaming and fast local transfers.

• Socket LGA 1851 with support for Intel Core Ultra processors, so you are stepping into the current generation of Intel.
• Four slots for DDR5 memory, up to 256 GB and up to 8666+MT/s (OC), which is a serious resource for multitasking and heavy applications.
• One PCIe 5.0 x16 slot for a graphics card, which operates at x16 and is ready for the latest GPU generations.
• Three M.2 slots: 1 x Blazing M.2 PCIe Gen5x4 to CPU for maximum fast NVMe SSD and 2 x Hyper M.2 PCIe Gen4x4 for additional high-speed storage space.
• Four SATA 6Gb/s ports plus support for RAID 0, 1, 5, 10 for flexible configurations between capacity, speed, and data security.
• Built-in Realtek Dragon RTL8125BG 2.5G LAN, which provides above standard gigabit connectivity for faster network operation.
• The audio subsystem with 7.1 CH HD Audio (Realtek ALC897) provides decent surround sound for gaming and movies without an external sound card.
• Built-in M.2 Key E slot for WiFi/BT module, so you can easily add wireless connectivity if needed, although there is no built-in Wi-Fi out of the box.
• Standard ATX power supply configuration with 1 x 24-pin ATX and 1 x 8-pin 12V connectors for stable power to the CPU and motherboard.

Who it is suitable for
This motherboard is a good choice for mid-range to more serious builds with Intel Core Ultra – gaming at high settings, streaming, working with many open applications, or light productivity/creative tasks. It is also suitable for compact systems with very fast NVMe storage and 2.5G network. If you are looking for built-in Wi-Fi or an extreme overclocking platform with a huge number of PCIe slots, you may find such extras lacking here.

The combination of PCIe 5.0 x16, Gen5 M.2, high DDR5 support, and 2.5G LAN makes ASRock B860M PRO-A a very sensible base for a modern and long-term Intel system in a compact Micro ATX case.
