USB 3.0 header splitter?

[rhodders]

Hi all,
I've seen a Y cable that splits the MoBo 20-pin header into two seperate USB 3.0 ports, but is there one that splits a single header into two?
The problem I have is I have a case with 2 USB 3.0 ports and a 3.0 adapter that came with my G1.Guerrilla that also has two ports. Problem is the MoBo only has a single 20-pin header connection. I suppose I could just leave off the 3.5" adapter, but why should I when I have it to use. So, is there an adapter out there that allows me to use both through the only USB 3.0 header that I have?

Is this what you are looking for?

I think you're looking for something like this only USB 3.0.

If you are, maybe NZXT website will be able to help you.

Just get a usb3 extension cable and run it out the back to the rear usb3 ports that your not going to really use anyways.

there is also one to connect 4 ports via 2 internal header

Hi, did you ever find a solution to your problem because i'm in exactly the same position. Spare usb3 panel but 1 usb3 header that is already used by my cases front usb3 ports.
i don't think any of the answers understood the problem. have you had any luck?

Yes, I think this is exactly what rhodders meant. I was actually looking for one too - thanks for the link, this is perfect!

Awesome!!! This is exactly what I've been looking for. I was going to pick one up as well! I was just curious if this effects any of the speeds from the different ports, rather then the single dedicated header?

Don't buy a splitter to achieve what you are trying to. They are not very common and for a good reason... It would be easier, cause less cable clutter and approximately the same cost to buy a PCI-E USB 3.0 card which has an internal 20 pin header. You can then run the 20 pin connector from an internal bay USB card reader/hub to this header, allowing you to run any of the computer case USB 3 ports to the single 20 pin motherboard header.

But that uses up pcie lanes, which could otherwise be used for something else.

DO NOT use these - UNLESS you only use one of the ports at a time. Plugging a device (type 2 or 3) in both ports will mess you up.
1) Both devices will try to signal the host as to type of device connected.
2) Both usb devices will try to ID themselves over the same port (this will really confuse the OS as to WHAT is plugged in.).
3) IF the stupid Y cable split out the two pair of superspeed channels then neither port will work at superspeed (ignoring all the OTHER electrical signaling problems) because superspeed requires BOTH channels to function. And when that failed, the mobo & devices will try to fall back to the original single usb 2 channel with it's pull-up resistor signaling. Where again two devices with interfere with each other.
TOTAL FAIL. !!

Why was this never a problem with USB 2.0? You can multiply 2.0 ports limited only by power requirements. For years we made cables to split internal headers as many as 10 ways.
