Does a USB 3 19-Pin Y connector exist?

Looking at that case I only noticed (1) USB 3.0 and (2) USB 2.0 @ the Front 'Ports' so I would assume the case has a USB 3.0 pass-through and a couple USB 2.0 standard headers.

So if the Case isn't equipped with a 20-pin and you need a 20-pin (MOBO) to Y-Female then:

HDE (TM) 2 Port USB 3.0 A Female to 20 Pin Y Cable - http://www.amazon.com/HDE-Port-USB-Female-Cable/dp/B006...

Specs:
Front ports
- 2 x USB 2.0
- 1 x USB 3.0
- Audio In and Out (HDA and AC’97 compatible)

Thanks for your reply but everything is as I originally stated; so that won't work. (The Antec folks update their hardware first, then their Web site and Owners' Manuals when they get around to it; so don't go by either of those.)

Unless the Model # changed then I never see a sudden change in specs.

Then it's an oddball design to have (3) USB 3.0 Ports. If that's the situation then no you cannot split the 20-Pin into (3) USB 3.0 Ports with out the use of a USB 3.0 HUB and/or a 20-pin for the (2) USB 3.0 @ Front (+) a USB 3.0 Pass-through to the Rear I/O of the MOBO. A HUB is IMO a bad option which leaves the option as I said <or> have a dead (1 of 3 USB 3.0).

Q - What EXACT USB Connectors came with your Case?
Q - How many Blue 'Front ports' and Black 'Front ports' with your case?

Please provide a link to your Case.

Well, the model # didn’t change, just the specs. As I said, EVERYTHING that I originally posted is correct. There are, indeed, THREE BLUE front ports. You seem to be skeptical; if you email them they will confirm what I am saying. Anyway, Asus said they will be sending me a USB 3 to USB 2 adapter so I can use that to plug the 19-pin USB 3 case cable into the motherboard's USB 2 connector. Then, rather than having one of the three front ports dead, it will be a USB 2 (along with the two USB 3s).

I just want to be sure of one thing: The maximum number of USB 3 ports that can be directly attached a single motherboard 19-pin connector (without a HUB) is two. Is that correct?

Thanks, jaquith, for that good answer. That's exactly what I needed to know.
Best regards,

the Original Poster is correct. At least, I am experiencing the exact same problem.

I purchased an Antec NineHundred Two V3 from NewEgg on 12-21-2012. NewEgg currently advertises and is still stating that it has the following front ports:

Qty: 1 USB 3.0
Qty: 2 USB 2.0

But wht they sent me was the exact same case, with QTY: 3 3.0 USB. Two of the connectors are spliced together into one connector to plug into your MoBo. the 3rd USB 3.0 has its own seperate 19-pin USB connector to plug into the Mobo. Most Mobo's only have 1 spot for this connector though.

So dont question the validity of the original poster anymore. To help the original poster out, you can order a usb 19 pin card, that will screw into the back of your computer similar to a video card, it plugs into the PCI 2.0 slot of your mobo. This will provide you an additional connector.They can be found on Newegg for around $20.

You can also go the route of what Antec is suggesting, which is an adapeter so that you can connect it into the USB 2.0 outlet on the Mobo. I think you will lose the USB 3.0 technology, thus making it a USB 2.0 though.

I am looking for this 3-way Y-type splitter also. Please update if you find one.
