ASRock B860 Pro-A WiFi — Value LGA1851 ATX Motherboard

A dependable, budget-friendly B860 ATX board forIntel Core Ultra Series 2, keeping PCIe 5.0, DDR5, Wi-Fi 6E and 2.5GBE networking in a clean, streamlined design.
Intel B860 · LGA1851DDR5 up to 8666+ MHz OCPCIe 5.0 x16Wi-Fi 6E · 2.5GBE LAN
The ASRock B860 Pro-A WiFi (part number 90-MXBRL0-A0UAYZ, EAN 4711581490253) is an entry-level ATX motherboard for Intel® Core™ Ultra Series 2 processors on the LGA1851 socket, built on the B860 chipset and tuned by the Pro-A line for stability, durability and everyday reliability at the lowest cost. It still keeps the essentials — a reinforced-steel PCIe 5.0 x16 slot, a Gen5 M.2 socket, DDR5 memory, Wi-Fi 6E and a Dragon 2.5GBE LAN. Typically in stock with fast delivery across Cyprus.
Compatibility: Supports onlyIntel Core Ultra Series 2 (Arrow Lake) CPUs on the LGA1851 socket — not compatible with LGA1700 (12th–14th Gen) chips. Uses DDR5 memory only (no DDR4), with Intel XMP 3.0x profiles. Standard ATX form factor (30.5 × 24.4 cm). Note: this is the value Pro-A model — B860 supports memory overclocking but not CPU core overclocking, and it has no Thunderbolt and Wi-Fi 6E (not Wi-Fi 7). It does include a rear USB 3.2 Gen2x2 Type-C at 20GB/s.

Frequently Asked Questions

Which CPUs does the B860 Pro-A WiFi support?
It supportsIntel Core Ultra Series 2 (Arrow Lake) processors on the LGA1851 socket. Older LGA1700 chips (12th–14th Gen Core) are not compatible.
Does it have Thunderbolt or Wi-Fi 7?
No — this value model has no Thunderbolt (but includes a 20GB/s USB 3.2 Gen2x2 Type-C), and wireless is Wi-Fi 6E (802.11axe), not Wi-Fi 7.
Can I overclock my CPU on B860?
B860 supports DDR5 memory overclocking but not CPU core overclocking — that requires a Z890 board. It is ideal for value builds with non-K Core Ultra chips.
Does it support DDR4 memory?
No. It uses DDR5 only — four DIMM slots up to 256GB, with speeds to 8666+ MHz OC and Intel XMP 3.0x profiles.
Singular Expert Insight
The B860 Pro-A WiFi is ASRock's most affordable route into the Core Ultra Series 2 platform, and it keeps the two things that matter most for future-proofing — a reinforced-steel PCIe 5.0 slot and a Gen5 M.2. It trims extras like Thunderbolt, premium audio and Wi-Fi 7 to hit its price, so if you want those, step up to the B860 Lightning or a Z890 board. For a dependable, no-fuss build it is excellent value. Pair it with an XMP-rated DDR5 memory kit for the best performance.

Buyer's Guide

Buy it if
You want the most affordable, reliable Core Ultra Series 2 board that still keeps PCIe 5.0, Gen5 M.2, Wi-Fi 6E and 2.5GBE.
Skip it if
You want Thunderbolt, premium audio, Wi-Fi 7, or CPU core overclocking for a K-series chip.
Also consider
The ASRock B860 Lightning WiFi for Thunderbolt 4 and ALC1220 audio, or a Z890 board for CPU overclocking and Wi-Fi 7.
