ASRock B860M Pro-A Motherboard, LGA 1851, Micro ATX, DDR5

The ASRock B860M Pro-A is a micro ATX motherboard for Intel CPUs, built around the Intel B860 chipset and the LGA 1851 socket. Its main appeal is room to grow: four DDR5 memory slots and three M.2 slots on a compact board, which makes it great value for a modern desktop build.

  • Socket: LGA 1851 (Socket V1)
  • Chipset: Intel B860
  • Form factor: micro ATX
  • Memory: DDR5-SDRAM, 4 slots
  • M.2 slots: 3
  • Wi-Fi: No

Description

LGA 1851 Socket with the Intel B860 Chipset

The board uses the LGA 1851 (Socket V1) socket paired with Intel's B860 chipset, so it's aimed at builders putting together a system on Intel's current desktop platform. It's a sensible base for a new PC rather than a stopgap, and leaves budget for the parts that matter most to you, such as the CPU or graphics card.

Four DDR5 Slots for Flexible Memory Upgrades

With four DDR5-SDRAM slots, you can start with two memory modules and add more later instead of replacing what you already have. That's handy if you want to keep the upfront cost down now and expand memory once your workload grows, whether that means more browser tabs, bigger projects or more demanding games.

Three M.2 Slots for Fast Storage

Three M.2 slots let you run your system, games and files on separate drives without needing extra adapters. For a micro ATX board, that's a generous amount of storage expansion, and it keeps the build tidy because the drives sit directly on the motherboard rather than taking up drive bays or adding cables.

Who it suits

This board suits anyone building a compact Intel desktop on the LGA 1851 platform: home and office users, gamers on a sensible budget and DIY builders who want DDR5 and plenty of M.2 storage in a micro ATX case. It has no built-in Wi-Fi, so it works best with a wired network connection or a separate wireless adapter.

Questions & answers

Which processors does this motherboard support?

It has an LGA 1851 (Socket V1) socket and the Intel B860 chipset, so it takes Intel processors made for that socket. Check the manufacturer's CPU support list for specific models.

Does it have built-in Wi-Fi?

No, this motherboard has no Wi-Fi. For wireless networking, you'll need a separate adapter.

Will it fit my case?

It's a micro ATX board, so it fits cases that support the micro ATX form factor. The manufacturer doesn't list exact dimensions in these specifications.
