SlimSAS SFF-8654 to U.2 SFF-8639 NVMe cable
This PCIe 4.0 cable connects a male SFF-8654 4i port to a female U.2 SFF-8639 NVMe SSD. It is built for users who need to add high-speed NVMe storage to systems with a SlimSAS interface. The 1.6ft length suits compact server or workstation chassis. It includes a 15-pin SATA power connector for the drive.
Straight male-to-female connectors simplify the link
The straight SFF-8654 4i and straight U.2 SFF-8639 ends plug directly into the motherboard or backplane and the SSD without angled adapters. Route the 50cm cable cleanly to avoid sharp bends near the latch. Ensure the 15-pin SATA power lead reaches the power supply. Verify the host port is wired for PCIe 4.0 x4, not SATA, or the drive will not be detected.
Four lanes at 16 GT/s deliver full PCIe 4.0 x4
This headroom handles demanding NVMe workloads such as database logging, virtualization storage and large dataset ingestion. The link runs out when the host controller or SSD hits its own queue-depth or thermal limits. It does not support SATA protocol drives on the U.2 side. Builders needing more than four lanes must use a different host connector.

Questions about this item
How can I verify the cable is delivering the rated 16 GT/s transfer rate after connecting it?
The link speed is negotiated by the host controller and NVMe SSD; check the PCIe link width and speed in your operating system or BIOS to confirm it is running at PCIe 4.0 x4.
What connectors and accessories are included with the 1.6ft cable, and what must I source separately?
The cable has a male SFF-8654 4i plug on one end and a female U.2 SFF-8639 receptacle with a 15-pin SATA power connector on the other; you must provide the NVMe SSD and a SATA power cable from your power supply.
Which version of this cable should I choose for a PCIe 4.0 NVMe drive?
This model LLS-CB-1SS1UT-01 is built to the PCIe 4.0 specification and supports 16 GT/s across 4 lanes, making it the correct choice for PCIe 4.0 NVMe SSDs.
