What wire is this

[PCN00B123]

Long story short , bought a new case to put my components in. Turns out the psu cables are too small and dont fit across to the mobo. I cant buy extensions because its an acer mobo and psu with a 12pin connector.

I've addes all the components back into the old Acer case but there is one wire which i have no idea what it is and where it goes. It comes from the case and it's colour coded black red, white blue and white orange and its got nine pins (ten pins if you count the one thats blocked)

The PC is an acer predator G3 605 . I was hoping someone could tell me where this wire goes

Thank you in advance

Any chance you could upload a picture of the pin in question?

It sounds like a dual USB cable feed(from front panel of PC?)that should connect to a 9-pin header on the motherboard.
