How to choose a motherboard?Motherboard is the main part of any computer. Here's how to choose the right one for work, play and entertainment

Reincarnation of a Legend

The ASRock B860 Steel Legend WiFi motherboard is perfect for creating a stylish "white build." Its premium design harmoniously blends with ASRock Polychrome Sync lighting and massive heatsinks, which effectively cool the VRM area, chipset, and M.2 drives. The Lite Release design simplifies the system assembly and maintenance process. Among the built-in modules are Wi-Fi 6E and Bluetooth 5.3, providing high-speed data transmission and stable wireless connection without unnecessary cables. An additional advantage is the USB4 port with support for Thunderbolt 4 interface, which offers data transfer speeds of up to 40 Gbps and the ability to connect monitors with 4K / 8K resolution and modern gaming peripherals. The model is equipped with a high-quality Nahimic audio system, a LAN 2.5 Gbps network port, and supports extensive customization capabilities through ARGB lighting.

Power Distribution System

The board is designed to handle high loads and is excellent for overclocking. It is based on an 18-phase power scheme with a Dr.MOS controller, which provides stable current delivery to key nodes without voltage droops. Reinforced Hi-Density connectors are highly durable, have minimal resistance, and prevent localized overheating. The Intel B860 chipset supports PCIe 5.0 interface and Intel Core Ultra Series 2 processors, optimized for working with artificial intelligence algorithms. The functionality is complemented by two special Ultra USB Power connectors, designed for power-intensive accessories such as gaming headsets, audio devices, and peripherals. They maintain stable power even under high load, are protected from interference, and prevent signal distortion.
