Can anyone confirm that the USB 3.1 Gen2 Type-C Port on the back IO Panel is available during UEFI boot for NVME SSD clean install of Win10?

I won't waste time on sourcing a USB 3.1 stick if it isn't available during UEFI Bios boot for OS installation.

I can follow the steps to enable UEFI NVME boot drive access for the install, just need to know which USB ports will be available at post.

Some older boards only enabled USB 2.0 during post so just checking.

Thanks

2.0 only during post is a few generations old at this point.

The Type-A ports certainly are enabled at post..... no reason to suspect the Type-C wouldn't be also.

Given the Type-A and Type-C ports have the same speed though, I wouldn't go out of my way to source a Type-C drive. If you already have one on hand, then ....sure? but you'd achieve the same thing using the Type-A, which you're more likely to have available to you.

Not based on 3.1/3.1 Gen2/3.2 Gen2 (all the same thing), which is what's implemented on that board.
  • 2 x USB 2.0 Ports (Supports ESD Protection)
  • 1 x USB 3.1 Gen2 Type-A Port (10 Gb/s) (Supports ESD Protection)
  • 1 x USB 3.1 Gen2 Type-C Port (10 Gb/s) (Supports ESD Protection)
  • 4 x USB 3.1 Gen1 Ports (Supports ESD Protection)

Newer 3.2 Gen 2x2 can do 20 Gb/s.
