PCIe Gen 5.0

Length 2.1 ft / 65 cm

  • Supports 32 GT/s per lane for PCIe 5.0 performance
  • Connects two U.2 NVMe SSDs via dual SFF-8639 ports
  • Includes 15-pin SATA power cable for integrated power delivery
  • Shielded copper conductors ensure reliable signal integrity
  • 65 cm length fits standard server and workstation chassis

Double U.2 expansion

This PCIe 5.0 MCIO x8 cable splits one 74-pin host connector into two SFF-8639 U.2 ports, letting you run two NVMe SSDs from a single slot. It targets builders who need high-density storage without occupying extra PCIe lanes.

Straightforward routing

The 65 cm length and straight male-to-male ends simplify cable management in tight chassis, while the integrated 15-pin SATA power lead feeds both drives from one source. Shielded copper conductors and SAS 4.0 compliance keep signal integrity at 32 GT/s per lane, but the fixed connector orientation may clash with crowded backplanes.

Verify host and drive fit

Confirm your motherboard or add-in card exposes an MCIO x8 header wired for PCIe 5.0 x8 bifurcation, and that each U.2 SSD accepts a straight SFF-8639 plug with 15-pin power. The cable does not adapt to OCuLink, M.2 or slimline SAS sockets, so those interfaces cannot be used.

Questions about this item

How can I verify the cable is running at PCIe 5.0 speeds after connecting two U.2 NVMe SSDs?

Check your system BIOS or an OS tool such as nvme-cli to confirm each drive negotiates a 32 GT/s link across the 8-lane MCIO x8 connection, giving up to 256 Gbps aggregate throughput.

What connectors and power cables are included, and what must I supply separately?

The box contains one 65 cm cable with a straight male 74-pin MCIO x8 plug, two straight male 68-pin SFF-8639 U.2 ports, and an attached 15-pin SATA power lead; you must provide a motherboard or add-in card with an MCIO x8 receptacle and a free SATA power connector from your PSU.

Should I choose this 65 cm Gen5 MCIO x8 cable or the 50 cm Gen4 version for my build?

Select this 65 cm cable when your platform supports PCIe 5.0 and you need the longer reach for dual U.2 NVMe drives; choose the 50 cm Gen4 model only if your hardware is limited to PCIe 4.0 and the shorter length fits your chassis.
