4Port USB 2.0 Header Extension Cable 30cm, Dual 9Pin Male to 4 USB 2.0 Female with 120mm PCIE Slot Bracket, Desktop PC Chassis Rear Panel USB Port Expansion Adapter

This practical internal PC extension cable turns your motherboard onboard dual 9pin USB 2.0 frontpanel header into four accessible USB 2.0 female ports at the chassis rear side. Equipped with a 120millimeter standard PCIE metal slot bracket, it occupies one vacant PCIE expansion slot position on your desktop case backplate for secure mounting.

Measuring 30 centimeters in cable length, it offers reasonable slack for tidy cable routing inside computer cases and avoids excessive tangled internal wiring. Two 9pin male connectors directly plug into the motherboard native USB2.0 header, no soldering or modification required. Delivers full USB 2.0 480Mbps transfer speed, backward compatible with USB 1.1 devices. It works well for connecting mice, keyboards, Udisks, card readers, USB hubs and other lowpower, lowbandwidth accessories.

Solid metal bracket with screw mounting hole keeps ports steady and prevents shaking or loose contact during frequent plugin and unplug operations. Durable insulated cable jacket resists abrasion inside the case environment.

Important notes: This is USB 2.0 only and cannot achieve USB3.0 speed. Your motherboard must have available dual 9pin USB2.0 internal header; the cable will not work without this matching interface. Not suitable for highpower USB devices requiring large current output. Perfect for PC assembly, rearport expansion or replacing broken builtin chassis USB ports.
