What this cable connects
The Vszerda LLS-CB-1MC2UT-01 is a PCIe 5.0 MCIO x8 to dual SFF-8639 U.2 NVMe cable with integrated 15-pin SATA power. It links one 74-pin SFF-TA-1016 MCIO host connector to two 68-pin U.2 drive ports, supporting 32 GT/s across eight lanes. The 40 cm black assembly is built to SAS 4.0 and PCIe Gen5 specifications and remains backward compatible with PCIe 4.0 systems. It targets builders adding high-speed U.2 storage to a compatible MCIO-equipped motherboard or controller.
Build integration and slot usage
The cable consumes a single MCIO x8 port on the host side while freeing two U.2 bays for NVMe SSDs, removing the need for separate power adapters thanks to the included 15-pin SATA power lead. Male-to-male terminal gender means both ends plug directly into matching female receptacles without gender changers. Backward compatibility with PCIe 4.0 lets the same cable serve current and previous-generation platforms, though the host must provide an MCIO x8 interface and a SATA power connector from the PSU.
Signal integrity and power delivery
Designed to SAS 4.0 and PCIe Gen5 standards, the 40 cm length helps maintain signal quality at 32 GT/s while the integrated 15-pin SATA power cable delivers stable power to both U.2 NVMe SSDs. The black jacket and 74-pin to dual 68-pin wiring follow SFF-TA-1016 and SFF-8639 pinouts for reliable enterprise-grade operation. No active cooling or additional signal conditioning is required on the cable itself.

Questions about this item
Will the PCIe 5.0 32 GT/s link saturate before the U.2 drives hit their rated throughput?
The cable carries an 8-lane PCIe 5.0 link at 32 GT/s, so the interconnect itself will not be the first bottleneck under sustained use.
Does the 40 cm cable add noticeable heat or noise when running two NVMe SSDs all day?
The passive 1.3-foot cable has no active components, so it generates no noise and negligible heat during continuous operation.
What power connector must my system already provide for the integrated 15-pin SATA power lead?
You need a standard 15-pin SATA power connector from your PSU to supply power to the two U.2 NVMe SSDs.
