Motherboard Asrock B860M PRO RS

Asrock B860M PRO RS is a micro ATX motherboard with LGA 1851 socket and Intel B860 chipset, aimed at a stable mid-range build with the latest generation of Intel Core Ultra processors. You get a modern DDR5 platform with up to 256 GB RAM and a decent set of slots and connectors for a compact yet serious system. The standout features are mainly the PCIe 5.0 x16 slot for GPU and the combination of Gen5 / Gen4 M.2 slots for fast NVMe drives. The board does not have built-in Wi-Fi, but it has an M.2 slot for adding a module if needed.

What you get

With LGA1851 and support for Intel Core Ultra processors, this board is a good foundation for a new generation gaming or workstation machine. The four DDR5 slots with up to 8666+ MT/s (OC) give you plenty of flexibility – from a basic 2x16 GB kit to heavy scenarios with up to 256 GB RAM for more serious productivity. For storage, you have 3 x M.2 slots: one PCIe Gen5x4 for your fastest NVMe and two more Gen4x4 for additional drives, plus 4 x SATA3 with support for RAID 0/1/5/10 for classic SSD/HDD arrays. The built-in 2.5G LAN provides higher network bandwidth than standard gigabit, while Realtek ALC897 7.1 audio is more than sufficient for gaming and multimedia without a separate sound card.

• Socket LGA 1851 with Intel B860 chipset – ready for Intel Core Ultra processors and a modern platform for your future upgrades.
• Support for DDR5 memory in 4 slots with a capacity of up to 256 GB and speeds of up to 8666+ MT/s (OC) for high bandwidth and dual-channel configuration.
• Three M.2 slots: 1 x PCIe Gen5x4 from CPU and 2 x PCIe Gen4x4 from the chipset, allowing a combination of super-fast system disk and additional NVMe for gaming and projects.
• 4 x SATA3 6.0 Gb/s with RAID 0/1/5/10 for flexible configurations with SSD and HDD – from maximum speed to more secure storage.
• Main PCIe 5.0 x16 slot for GPU, plus PCIe 4.0 x4 additional slot for expansion cards if you need more features.
• M.2 (Key E) slot for WiFi/BT module – no built-in Wi-Fi, but you can easily add wireless connectivity later.
• A rich set of USB: USB 3.2 Gen2x2 Type‑C (rear), USB 3.2 Gen1 Type‑C (front), 7 x USB 3.2 Gen1 Type‑A and 6 x USB 2.0 for all peripherals and front panel.
• Built-in 1 x Dragon RTL8125BG 2.5G LAN for faster and more stable network connection compared to standard 1G LAN.
• Realtek ALC897 7.1-Channel audio codec for decent multi-channel sound transmission without the need for a separate card in most scenarios.

Who it is suitable for

Asrock B860M PRO RS is suitable if you want a compact micro ATX machine with the new generation Intel Core Ultra, focused on gaming, productivity, and even more serious workloads with plenty of RAM and fast NVMe drives. It is suitable for mATX format cases, where you want to balance between expandability and size. If you prioritize built-in Wi-Fi and an “all-in-one” solution without adding a module, there are more suitable alternatives.

The combination of LGA1851, DDR5, PCIe 5.0 for GPU, and Gen5 M.2 slot makes this board a very sensible foundation for a modern, long-term build, without unnecessary luxury, but with the right features in the right places.
