USB 3.0 20-Pin Female to Female Motherboard Extension, 0.5 m

Builders know the gap: the case’s front-panel USB 3.0 cable is moulded for a mid-tower, and the motherboard header lives somewhere else entirely. This internal extension closes it: 20-pin USB 3.0 female to 20-pin female, 0.5 m, carrying both SuperSpeed ports’ lanes between header and harness. Model U3MBAF010; gold-plated pin plate at 15 microinches; 100% electrical test before packing.

Shielding is the internal-grade spec worth paying for: aluminium foil plus braid, strong anti-interference ability for a cable that routes past power supplies, spinning drives and case fans. The conductor is 100% copper with a maximum speed of 4.8 Gbps (SuperSpeed, ten times USB 2.0’s 480 Mbps), backward compatible with USB 1.1 and 2.0, and system support runs Windows Me/2000/XP/Vista/7/8, Mac and Linux. Outer diameter is 6 mm — stiff enough to route cleanly, slim enough for cable combs.

Key features

• USB 3.0 20-pin female to female extension, 0.5 m
• Aluminium foil and braid shield, strong anti-interference
• 100% copper conductor, gold-plated pins (15u″)
• 4.8 Gbps SuperSpeed, backward compatible 1.1 / 2.0
• 100% electrical test; model U3MBAF010

Specifications

An honest note on connectors: the 19-pin and 20-pin names describe the same internal header — one position is keyed. Seat the plugs with the latch oriented as on the board; the keyed pin makes a wrong seating a physical struggle, not a silent fault.

Typical applications

• Bridging case front-panel leads to distant headers
• Custom internal USB 3.0 routing in modded cases
• Test benches that re-plug headers frequently
