Ideal for PC builders and enthusiasts needing a reliable USB 2.0 connectivity solution for custom rigs, workstation upgrades, or retrofitting components to modern motherboards. Easy installation with antistatic shielding; plugandplay functionality that preserves motherboard integrity during intensive operations. Precisely molded connectors with gold plating for stable data transfer rates up to 480 Mbps and reduced signal interference during performance computing tasks. Converts a motherboard 19pin USB 3.0 header into two USB 2.0 ports, optimizing compatibility with ARGB controllers, liquid cooling systems, and peripheral devices through seamless motherboard expansion. Use scenario: upgrading a modern motherboard to support legacy USB 2.0 devices such as keyboards, mice, or USB storage, while keeping other USB functionality intact. Use scenario: building a custom rig that includes ARGB lighting or a USB controlled liquid cooling setup that relies on USB 2.0 connectivity. Use scenario: retrofitting or expanding an older case or system that requires additional USB 2.0 ports without changing the motherboard.
