USB 2.0 IDC 50cm Internal Cable

This 50 cm internal USB cable connects a motherboard’s 5-pin USB 2.0 internal header to a USB 2.0 Type-A female port using an IDC-style female connector. Its dimensions and materials are engineered for desktop PC integration: total length 50 cm (±1 mm tolerance), black PVC outer jacket, and internal wires colour-coded per USB 2.0 specification (red = +5V, green = D+, white = D−, black = GND). The connector housing is moulded plastic; contact points are plated metal for corrosion resistance and low-contact resistance. Fully compliant with USB 2.0 signaling standards and designed for direct attachment without intermediary boards or converters. The cable’s structural rigidity prevents kinking or twisting during routing inside tight chassis spaces, while its moderate length avoids strain on motherboard headers or unnecessary bulk behind the motherboard tray. Because it uses only the standard four USB 2.0 signals plus ground (no extra pins), it avoids compatibility issues with legacy or budget motherboards that omit optional VBUS detection lines. Suited for users upgrading or modifying PC cases, building embedded systems, integrating USB peripherals into test fixtures, or adding internal USB ports for diagnostics and firmware flashing. Installation requires attention to orientation — verify pin 1 alignment before pressing in — but once seated, the IDC grip holds reliably through thermal expansion and mechanical shock encountered in daily operation.
