Vszerda PCIe 5.0 MCIO x4 to U.2 Cable

This Vszerda cable connects a PCIe 5.0 MCIO x4 host port to a U.2 SFF-8639 NVMe drive. It targets server and storage builders who need 128 Gbps throughput over four lanes in dense racks. The 1.6ft length suits short internal runs. An integrated 15Pin SATA power lead supplies the drive directly.

Check host connector and drive bay clearance

Verify the motherboard or backplane presents a male MCIO x4 receptacle before ordering. Confirm the chassis can route a 50cm cable between that port and the U.2 drive bay without sharp bends. Ensure the power supply has a free SATA power connector for the 15Pin plug. The cable carries both data and power in one assembly.

Thermals noise and power in normal use

Passive copper conductors add no fan noise and draw no power themselves. The 128 Gbps link runs at PCIe 5.0 and SAS 4.0 signalling rates without active cooling. Heat stays limited to the drive and host controller. The slim 0.6mm connector profile does not block airflow around adjacent cards or drives.

Questions about this item

Does the Vszerda LLS-CB-1MC1UT-01 cable include the 15-pin SATA power lead, or must that be purchased separately?

The cable has an integrated 15-pin SATA power connector built into the assembly, so no separate power cable is required for the U.2 NVMe drive.

Should I choose a different length or a SAS-only version for a PCIe 5.0 server installation?

This model is 50 cm long and supports both PCIe 5.0 and SAS 4.0; no other lengths or protocol-specific variants are offered for this part number.

What does the 128 Gbps rating mean when the cable is connected to a U.2 NVMe SSD in a live server?

It provides four lanes of PCIe 5.0 bandwidth, delivering up to 128 Gbps aggregate throughput to the drive when the host controller and SSD also support Gen5 speeds.
