This USB3.0 splitter card is designed to improve cable management while expanding motherboard USB3.0 connectivity. It is compliant with 19pin motherboard USB3 specifications and provides two 20pin outputs from a single 19pin input, effectively increasing available USB3.0 headers without compromising performance. Key features and benefits Cable management and capacity expansion: Achieve cleaner builds and doubled USB3.0 header capacity by converting a 19pin header to two 20pin outputs on compatible boards. Bidirectional 20pin port allocation: Flexible routing options to suit various motherboard layouts and case designs. speed performance: Supports 5 Gbps data transfer, enabling full USB3.0 speeds for connected devices. Compact, spaceefficient PCB: PCB dimensions are 65 x 21 x 10 mm, ideal for tight or compact PC builds. Compatibility: Expands motherboard USB3.0 connectivity with a 19pin female input to two 20pin splitter adapters, compatible with P7P55/USB3 series and other modern motherboards. Product details Function: 19pin female to two 20pin splitter adapters to increase USB3.0 header availability on compatible motherboards. Performance: Bidirectional 20pin port allocation with 5 Gbps data transfer speed. Size: PCB construction measures 65 x 21 x 10 mm for spaceconscious installations. Compatibility: Designed for 19pin USB3 specifications; compatible with P7P55/USB3 series and other modern motherboards. Who this is for PC enthusiasts, builders, and gamers who need multiple USB3.0 headers for peripherals (such as external storage, gaming peripherals, or other USB3 devices) without sacrificing data transfer speeds. Use scenarios Scenario 1: Build a clean, organized PC with enhanced USB3.0 capacity for frontpanel or internal connections while maintaining tidy cable routing. Scenario 2: Create multiple bandwidth USB3.0 headers for peripherals in a gaming setup, without reducing transfer speeds. Scenario 3: Install in a compact or small form factor build where space is limited, using the slim PCB to minimize clearance issues while expanding USB3.0 connectivity. Installation overview Connect the 19pin female connector to the motherboard USB3 header. Connect the two 20pin splitter adapters to the corresponding USB3 headers on the motherboard. Verify motherboard compatibility with 19pin USB3 specifications and ensure the two 20pin outputs align with available headers.
