Hi Guys,
I am trying to find an X570 itx/dtx or mATX motherboard with type E header as well.
I realize those delock
m.2 adapter and silverstone
PCIe adapter.
The m.2 adapter would occupies one m.2 slot hence won't work on Asrock X570 Phantom Gaming-ITX TB3, if you want NVME.
(Even those that comes with two m.2 slot would have problem to find a case with appropriate cut out on the back of motherboard)
The PCIe adapter would work on Asrock X570m Pro4, but again that is mATX.
So after an extensive searching, I found the following two adapters. I see some potential to route everything (kinda) internally without modifying your case here.
1.
Adapter for Type-C 24 pin female to Key A 20 pin female (mounting type)
There is one solution I can think off and I have no idea if it is theoretically possible.
1.1Mount this adapter somewhere inside the case or somewhere on the back of your case.
1.2 Plug in your Type E male included with your case into the Key A Female side of this adapter
1.3 Connect the Type-C end with "USB 3.2 Gen2 support Type-C to Type-A cable"
1.4 Connect the Type-A end of your cable to your USB 3.2 Gen 2 port (on IO shield).
2.
Flat Cable USB 3.2 Gen 2 Type-C 24 pin Female to Key A 20 pin female, panel mount
This adapter is similar to above but probably has better compatibility since we can route the Key A end near the front panel and the Type C end near IO shield.
Anyway, I have no idea how much this adapter cost. I wish it is cheaper then the delock solution, but you would have to factor in a Type-A to Type-C cable that support USB3.2 Gen2 as well. So if the price is
not right, shall we all give up on the TB3 and praying that a ROG Crosshair VIII Impact in on sale....
Lastly, there seem to be Key A and Key B when it comes to Type E male header.
I tried to read this document but can't really find a difference between those two keys.
