900D Connector question

I'm trying to connect all cables in my 900D

to the motherboard.

Most of them are Obvious, however the

right most connector on the following picture

puzzles me.

What is it used for, and where on my motherboard,

should it be connected to?

My mobo is an Asus Rampage V Extreme/U3.1

Any suggestion is welcome.

Appears thats a psu connection-sata

the clue is the usb symbol with the SS designation for superspeed or in layman's, it is the USB3 header, should be a red socket on the asus board.

Good catch Gonzo,even looking I still missed the symbol.

finally connected mine tonight, bummer that this has 4 usb 2 ports as I need to buy a USB3 to USB2 dongle now :(

 

damn rampage v extreme used the 2nd usb for the breakout box.

Ok, an USB3 connector. Thanks for the help.

 

What I also noticed is that the 900D makes it easy

to flip 5.25 hd drive bay in the case.

 

However, the Asus Rampage V Extreme/U3.1 comes with

something like a 5.25 hd drive bay for its OC command center,

and guess what, it is only a short bay!

 

So the 2 silver pins won't keep it in place.

And one cannot use screws to lock the bay.

Correct me if I am wrong.

 

Anyway, the connection problem is solved. Thanks again.

you're wrong. Mines locked in with the 4 screws provided m8
