I bought one directly off Lian Li for $28USD delivered. I had to email them directly and ask.

But I also bought one of these, so I wonder if I can use my USB 3.0 and USB 3.1 heard with this splitter.
I know it works with the 4 USB 3.0 ports of my last case.

I also have a Dark X299 I have to build and a the same case. I am hoping I can get both to work...
 

Thanks!
 
I looked at the PW – INC1TR. It has two problems.
1) This downgrades the USB 3.1 Gen 2 to the lower speeds of 3.0.
2) The part is no longer available.
 
I am looking for a full-speed USB Gen 2 solution.

Well this seems to be the same part here unless I messed up! This part is a lot more money...
I ordered mine RIGHT off Lian Li... Maybe this company made their own....

I would buy the Delock but its NO where to be had where I can find one... I am sure somebody else makes a card. Funny though the Moddy website says it will do full 3.1 speeds by combining the 2 channels into one. I don't know. Should I be able to get both to work for now that will good enough for now, even if not at full speed.
I am sure SOMEBODY else sooner or later will make internal USB 3.1 female header.

Welp the internet is amazing isn't it?
I found a USA supplier but it will take +/- 2 weeks and IT IS pricey @58.00 Plus change worldwide delivery is FREE....

Thanks KimbaWLion. I found the Grooves-inc.com folks last night also. It is a long lead time, but at least they are selling it. I don't see anyone else selling a USB 3.1 Gen 2 solution to this problem. Too bad EVGA did not put the connector on the board.
 
Thanks also to GGTV-Jon for you efforts.
 
I got to looking at the Delock part. There are two, very similar parts. They are 89801 and 89603
 
Item # 89801, Delock PCI Express Card > 1 x internal USB 3.1 Gen 2 key B 20 pin female
Item # 89603, Delock PCI Express Card > 1 x internal USB 3.1 Gen 2 key A 20 pin female


There are two differences I can find. The 89801 allows two devices to be connected (although only one plug is pictured.) The 89603 allows one device to be connected. The other difference is the 89801 has a "key B" 20-pin female connector and the 89603 has a "key A" 20-pin female connector. Ugh. And the photos are not reliable, because they do not show the correct number of plugs. I wonder what a "key A" and a "key B" are. I assume one pin is blocked, or similar.
 
I don't feel like waiting weeks, just to find out I got the wrong key. Call me wasteful, but I am going to buy both and see which one fits. Maybe, not likely--but maybe, I can return the other one.

Report back when you get everything so we can see what actually worked
Cheers

It might combine the data paths for the 10Gbs but doesn't the true 3.1 also have a higher amperage rating? If so then it is lacking in supported power delivery

Okay, finally figured it out. The Key A card supports 1 USB Type-C port or 1 Standard-A port. The Key B card supports 2 Standard-A ports. Since the Lian Li PC-O11 Air has a USB Type-C connector, I need the card with the Key A connector. That is the Delock Item No. 89603.
 
Side note: The connector from the front of the Lian Li case will fit either card. That is, it fits both the Key A card (Item # 89603) and the Key B card (Item # 89801). So much for this being a keyed connector, despite the name. Since the cable is coming from a Type C connector, I think it should only fit the Key A socket--especially when the connector is named "Key A".
 
I have not tried powering on either at this point, and I am not sure powering up the wrong card is a good idea. Pins 12 and 13 are TX2+ and TX2- for the Key A and the opposite, TX2- and TX2+ for the Key B. That is a big voltage difference, and is plenty of volts to blow up a chip.
 
Lian Li should have given more guidance with this. The Lian Li manual says absolutely nothing.
 
To cross check this, I looked at an ASUS motherboard board that has a built-in connector for the type of cable coming from the front of the Lian Li case. The pins are exactly the same as the documentation for a Key A 20-Pin Connector. I found the information in a pdf named USB3p1_Front_Panel_CabCon_Implment_Doc_Rev1p1.pdf, which is titled "USB 3.1/USB Type C Desktop Front Panel Cable and Connector Implementation Document" and is put out by "USB Implementers Forum, Inc." whoever that is. That document has the pin specifications for the Key A and the Key B connectors. They are very different.
 
Bottom line, I think it is the Key A and Part number 89603. I'll see if anything starts smoking or catches fire when I turn it on.

What are you going to be connecting on those ports?

If it is VR related I would say CPU lanes, if it is for contacting something like your phone then PCH

I personally do not own a VR device - I just know they do connect. Not if you were using a newer NVIDIA card with USB on the GPU card I would think using that would be better

The DeLOCK 89603 is very disappointing. The PCIe card did not seat well. The card seated into the motherboard loosely. When I screwed down the bracket the card popped out of the motherboard. I had to bend the bracket to get the card to seat at the same time the bracket was securely screwed. Also, the cable from the front panel of the Lian Li case did not seat securely. It kept wanting to pop out. I think this female connector and/or the male plug are designed poorly. There is no latch. While trying to press the male connector down hard, to see if that would seat it better, the SATA power connector crumbled in my hand. My hands are large, and fairly strong--but I am no muscle man. I don't feel like I used excessive force. I have been handling computer parts professionally since 1976. I have never had a part break like this before. The words Tinker Toy came to mind.

In any event, I did not get a chance to try the DeLOCK 89603 before it broke--so I don't know if this accomplished what I was setting out to accomplish.

I considered buying another DeLOCK 89603 to replace the one I broke. I decided a replacement would have the same problems, and my chances of breaking a second one would be high. So, I started looking around for another part that solves the same problem. After a lot of searching, I found the Lycom UB-152. See: http://www.lycom.com.tw/UB-152.htm. I like this design better, because the SATA power connection allows the cable to be connected in a saddle seating. Saddle seating is more natural for SATA power cables, because of the multiple connectors on the same cable. I am not sure how well the cable will route through my PCIe cards. The other card, with its end connector for SATA may easily be the superior design. My primary hope is the Lycom card will seat better and won't crumble in my hand. I looked high and low for someone who sold the Lycom UB-152 in the US. I had no luck until I searched by the product description. I found that, you guessed it, DeLOCK is selling this card as their 89906. Consequently, I placed another order with DeLOCK for an 89906, aka Lycom UB-152.

It will be interesting to see how the Lycom part fits. I am attaching images of the newly discovered part.
