ASRock B860 Pro RS WiFi — Value LGA1851 ATX Motherboard

The Race Sport (RS) evolution of the popular Pro series: a stylish, dependable B860 ATX board forIntel Core Ultra Series 2 with PCIe 5.0, DDR5, Wi-Fi 6E and 2.5GBE.
Intel B860 · LGA1851DDR5 up to 8666+ MHz OCPCIe 5.0 x16Wi-Fi 6E · 2.5GBE LAN
The ASRock B860 Pro RS WiFi (part number 90-MXBRK0-A0UAYZ, EAN 4711581490239) is an ATX motherboard for Intel® Core™ Ultra Series 2 processors on the LGA1851 socket, built on the B860 chipset. As the "Race Sport" evolution of ASRock's popular Pro series, it blends a modern, stylish look with reliable everyday performance. It keeps a reinforced-steel PCIe 5.0 x16 slot, a Gen5 M.2 socket, DDR5 memory, Nahimic audio, 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: B860 supports memory overclocking but not CPU core overclocking (that requires a Z890 board); this model 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 RS 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.
How is the Pro RS different from the Pro-A?
The Pro RS is the "Race Sport" evolution of the Pro series — it shares the same core B860 platform but adds a more stylish design, Nahimic audio and a pre-installed I/O shield for easier installation.
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 RS WiFi sits just above the plain Pro-A in ASRock's value B860 range: same reliable 10-phase platform, PCIe 5.0, Gen5 M.2, 2.5GBE and Wi-Fi 6E, but with a sharper "Race Sport" look, Nahimic audio and a pre-installed I/O shield that speeds up the build. Like all B860 boards it does memory OC but not CPU core OC, and skips Thunderbolt. For a clean, good-looking Core Ultra build at a keen price it is a strong pick. Pair it with an XMP-rated DDR5 memory kit for the best performance.

Buyer's Guide

Buy it if
You want a stylish, dependable value Core Ultra board with PCIe 5.0, Gen5 M.2, Wi-Fi 6E, 2.5GBE and a pre-installed I/O shield.
Skip it if
You want Thunderbolt, premium ALC1220/ALC4082 audio, Wi-Fi 7, or CPU core overclocking for a K-series chip.
Also consider
The B860 Pro-A WiFi for a plainer, lower-cost option, the B860 Lightning WiFi for Thunderbolt 4, or a Z890 board for CPU overclocking.
