ASRock B860 Pro RS LGA1851 ATX Motherboard

The ASRock B860 Pro RS is an ATX motherboard engineered for Intel's LGA1851 socket, providing a stable platform for Intel Core Ultra Series 2 processors. Its power delivery system is constructed with a 10+1+1 phase design using Dr.MOS components, which is managed thermally by aluminum heatsinks to maintain consistent performance during demanding tasks. This configuration is designed to provide reliable power and stability for modern PC builds. The board is built with DIY-friendly features, including a pre-installed I/O shield and a reinforced primary PCIe slot for heavy graphics cards.

This motherboard accommodates up to 256 GB of dual-channel DDR5 memory across four DIMM slots, with support for overclocking profiles to achieve speeds up to 8666 MHz. For storage, it offers a high-bandwidth PCIe Gen5 M.2 slot for primary drives, supplemented by two additional M.2 slots and four SATA III ports, allowing for flexible storage configurations. Expansion is handled by a primary PCIe 5.0 x16 slot and a secondary PCIe 4.0 x16 slot, providing connectivity for graphics cards and other peripheral devices.

Connectivity options include a Dragon 2.5 Gb/s LAN port for high-speed wired network access. The rear I/O panel is equipped with a comprehensive selection of USB ports, including multiple USB 3.2 Gen 1 Type-A ports and a USB 3.2 Gen 1 Type-C port. Video outputs consist of one HDMI 2.1 and one DisplayPort 1.4 port. For system customization, the board includes headers for Polychrome RGB lighting, which can be synchronized with other compatible components. The integrated audio is based on the Realtek ALC897 codec.
