ASRock B860M Pro RS Motherboard
A balanced Micro-ATX board for Intel Core Ultra (Series 2): four DDR5 slots, PCIe 5.0 graphics, three M.2 with Gen5 storage and 2.5G LAN — ready for serious mainstream builds.
LGA1851 · Intel B860 4x DDR5 up to 256GB PCIe 5.0 + Gen5 M.2 USB 3.2 Gen2x2 20Gbps
The ASRock B860M Pro RS is a Micro-ATX motherboard built around the Intel B860 chipset and the LGA1851 socket, designed for Intel Core Ultra Processors (Series 2). It pairs a 10+1+1+1+1 Dr.MOS power phase design with four DDR5 DIMM slots reaching DDR5-8666+ via overclocking, a PCIe 5.0 x16 SafeSlot for the GPU and three M.2 slots — one Blazing M.2 PCIe Gen5 x4 and two Hyper M.2 PCIe Gen4 x4 — backed by 2.5G Realtek LAN and a rear USB 3.2 Gen2x2 Type-C running at 20Gbps. There is no onboard Wi-Fi on this version; for built-in wireless, look at the B860M Pro RS WiFi.
Compatibility Note: Requires an Intel Core Ultra (Series 2) CPU for LGA1851. DDR5 only — DDR4 is not supported. Verify Micro-ATX clearance in your case before purchase. No onboard Wi-Fi on this model.

Technical Specifications
Frequently Asked Questions
Singular Expert Insight
Choose the B860M Pro RS if you want a balanced Micro-ATX board with PCIe 5.0 graphics, a Gen5 NVMe slot and four DIMM slots without paying for Wi-Fi. If you need built-in Wi-Fi 6E, step up to the B860M Pro RS WiFi. If you want a full ATX layout with more PCIe slots, look at the B860 Pro RS / Pro RS WiFi instead.
Buyer's Guide
Buy it if
You build a mainstream Core Ultra (Series 2) Micro-ATX system and want PCIe 5.0 GPU support, Gen5 NVMe and 2.5G LAN at a sensible price.
Skip it if
You need built-in Wi-Fi out of the box, more than two PCIe slots, or 10GbE — this is a wired Micro-ATX mainstream board.
Also consider
B860M Pro RS WiFi for the same board with Wi-Fi 6E + Bluetooth, or a B860 Pro RS for ATX layout and an extra full-length PCIe slot.
