Vszerda USB 3.0 Female Screw Mount to 20-pin Header 90° Cable 25cm

Front-panel USB 3.0 adapter for tight builds

This 25 cm cable converts a motherboard 20-pin header into a single USB 3.0 Type-A port with a screw-mount flange. The 90-degree angled header lets the connector sit flat against the board, which is useful in compact cases where a straight header would foul nearby components or the side panel. Builders adding front-panel USB 3.0 to a chassis that only provides a header will find the screw holes simplify panel mounting. The copper conductors support the standard 5 Gbps signalling rate.

Signal integrity over the 25 cm run

At 25 cm the trace length stays well within the USB 3.0 specification for passive cables, so sustained transfers at 5 Gbps remain stable without active re-drivers. The right-angle header reduces mechanical stress on the motherboard socket during repeated insertions, which helps maintain contact resistance over time. No external power is required; the cable draws bus power directly from the header. Performance is limited to the single-lane 5 Gbps rate inherent to the USB 3.0 header.

Simple header-to-panel installation

Align the 20-pin plug with the motherboard keying and press straight down; the angled body clears most tall capacitors and VRM heatsinks. Secure the Type-A flange to the case cut-out with the two supplied screw holes to prevent the port from pushing back during cable insertion. Common issues: reversing the header orientation (the key prevents damage but not a wasted minute), forgetting to enable the header in BIOS, or using a case cut-out that is too small for the flange. No drivers are needed beyond the OS USB 3.0 stack.
