ASHATA9pin USB Header Male 1 to 4 Female Extension Cable Card Motherboard,9 Pin USB Header Male 1 to 4 Female Extension Splitter Cable USB 9 pin Connector

Great item , had a new x299 board and only had one 9 pin header , I needed to run i\o cosair water and cosair commander and this was great I still have 2 more ports I can use. Dose what it is designed to do and at a good price

Does the job

Dead on arrival, tried to troubleshoot, but there really isn't anything to check on it other than things being connected.I would stick to a powered internal hub / splitter, rather than these passive ones.
