PCIe 4.0 x1 to U.2/U.3 adapter

This adapter adds a single U.2/U.3 SFF-8639 port to a desktop motherboard through a PCIe 4.0 x1 slot. It provides a physical interface conversion for compatible NVMe SSDs such as the PM1735 series. The card operates transparently to the operating system and requires no additional software drivers. It is a new component intended for internal installation.

For adding enterprise NVMe drives to consumer boards

The adapter suits builders who want to connect U.2 or U.3 NVMe drives to a system that lacks a native SFF-8639 connector. It does not support SATA or SAS SSDs, so buyers needing those drive types must look elsewhere. U.2 drives are not compatible with U.3 hosts, so drive and host compatibility must be verified before purchase. The single x1 lane limits bandwidth compared to wider slots.

Fits a free PCIe x1 slot and frees drive bays

Installation requires an available PCIe 4.0 x1 slot on the motherboard and a compatible U.2 or U.3 NVMe drive with an SFF-8639 connector. The card draws power from the slot and does not need external cables. Using this adapter frees internal 2.5-inch or 3.5-inch drive bays for other storage devices. Ensure the chassis has enough clearance for the installed drive and cable routing.

Questions about this item

What motherboard slot is required for the PCIe 4.0 x1 lane on this SA-093-XY adapter?

The adapter plugs into any PCI Express 4.0 x1 slot on the motherboard.

Will a U.2 NVMe drive such as the PM1735 work alongside an existing SATA SSD on the same system?

Yes, the adapter adds a U.2/U.3 SFF-8639 interface without changing speed or properties; the U.2 drive operates independently of any SATA devices.

How can I verify the PM1735 is running at PCIe 4.0 x1 after installing the adapter?

The adapter is transparent to the operating system and requires no drivers; check the link speed in the OS device manager or a tool such as NVMe CLI to confirm PCIe 4.0 x1 operation.
