Green PCIe x1 card with a silver SFF-8639 U.2/U.3 connector

LORDWORLD

LORDWORLD PCIe 4.0 x1 to U.2/U.3 SFF-8639 Adapter

SKU CH-M805-BGA0E

Adds a U.2/U.3 SFF-8639 port via a PCIe 4.0 x1 slot for NVMe SSDs like the PM1735 without driver installation

  • Adds U.2/U.3 NVMe support via single PCIe 4.0 x1 slot
  • Transparent pass-through keeps full SSD speed with no drivers needed
  • Works with U.2 and U.3 NVMe drives such as PM1735 series
  • SFF-8639 connector enables tri-mode controller compatibility where firmware allows
  • Simple form-factor conversion without signal alteration or software setup

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

This LORDWORLD adapter adds a single U.2/U.3 SFF-8639 port to a PCIe 4.0 x1 slot. It provides a physical interface conversion for compatible NVMe SSDs without altering signal speed or properties. The card operates transparently to the operating system and requires no software drivers. It is designed for motherboards with an available PCIe x1 slot.

Suits U.2/U.3 NVMe SSD installation

Builders wanting to connect enterprise U.2 or U.3 NVMe drives like the PM1735 series to a consumer motherboard can use this adapter. It does not support SATA or SAS SSDs despite the U.3 tri-mode standard. Buyers needing to attach SATA or SAS drives should look at a different host controller. The single x1 lane limits throughput compared to wider slots.

Driverless transparent operation

The adapter functions purely as a passive form converter, leaving drive performance characteristics unchanged. U.3 drives automatically negotiate NVMe mode on power-up using the SFF-8639 connector pin configuration. Dual-port NVMe functionality remains available on drives that support it. No bundled software or configuration utilities are included or required.

Questions about this item

Does the adapter need an available PCIe 4.0 x1 slot on my motherboard to work?

Yes, the card plugs into a PCIe 4.0 x1 slot to add one U.2/U.3 SFF-8639 interface for NVMe SSDs.

Will a U.2 NVMe SSD I already own run correctly when connected through this card?

U.3 is backward compatible with U.2, so your existing U.2 NVMe SSD will operate at its normal speed without driver installation.

How can I confirm the PM1735 drive is detected and running at full PCIe 4.0 speed after installation?

The drive should appear in BIOS and the OS device manager as an NVMe device with no extra drivers needed, showing its rated PCIe 4.0 performance.
