PCIe Gen 4.0

Length 1.6 ft / 50 cm

  • Connect two U.2 NVMe SSDs simultaneously via 74-pin MCIO x8 host connector
  • PCIe 4.0 16 GT/s per lane bandwidth across eight lanes for high-speed data transfer
  • 15-pin SATA power cable included to deliver stable power to both U.2 drives
  • Backward compatible with PCI-Express 3.0 systems for use in previous-generation platforms
  • Shielded copper conductors with 50 cm length support reliable signal integrity over the cable run

Dual U.2 NVMe expansion

This PCIe 4.0 MCIO x8 cable connects two U.2 NVMe SSDs to a single MCIO port on a compatible motherboard or controller. The 50 cm length suits typical server or workstation chassis layouts. It is built for users who need high-speed storage density without adding extra add-in cards.

Integrated power and dual connectors

A 15-pin SATA power lead is incorporated into the assembly, delivering power to both U.2 drives from one source. The MCIO 74-pin plug splits to two SFF-8639 68-pin receptacles, so each SSD receives its own data path and shared auxiliary power. Shielded copper conductors maintain signal integrity at 16 GT/s per lane.

Verify MCIO x8 port and drive form factor

Confirm your board provides an MCIO x8 connector that follows the SFF-TA-1016 pinout and supports PCIe 4.0 or 3.0 operation. Ensure the U.2 drives are 2.5-inch SFF-8639 devices, not M.2 or E1.S modules. Check that the 50 cm reach matches your drive bay placement and that your power supply has a free SATA power connector.

Questions about this item

Does the 15-pin SATA power connector need replacement over time?

The 15-pin SATA power connector is a standard interface; treat it like any internal power cable and reseat if contacts oxidise.

Will the 16 GT/s per lane rate drop first under sustained load?

The cable is rated for PCIe 4.0 at 16 GT/s per lane across eight lanes; sustained throughput is limited by the SSDs and host controller, not the cable itself.

Does the 50 cm shielded copper cable run hot or add noise when used all day?

Passive copper construction with shielding produces no audible noise and negligible heat; thermal load comes from the attached U.2 NVMe SSDs, not the cable.
