Questions about this item

Which slot on my motherboard must be free to install this M.2 M-Key NVMe to SFF-8643 U.2 adapter card?

You need an available M.2 M-Key slot on the motherboard that supports NVMe signalling.

Will this adapter card work with a PCIe 3.0 motherboard slot?

Yes, the card supports PCIe 4.0 and is backward compatible with PCIe 3.0, so it will function in a PCIe 3.0 slot.

How can I verify the NVMe U.2 SSD is recognised after connecting it through this adapter?

The drive should appear in BIOS or UEFI and in the operating system disk management utility once the SFF-8643 cable is seated correctly.
