Supermicro CBL-MCIO-1245U2Y-E MCIO x8 para 2x SFF-8639/U.2+Pwr 45cm G5 RoHS - cabo

High-density NVMe storage deployments demand a reliable, high-speed link between host controllers and U.2 SSDs. The Supermicro CBL-MCIO-1245U2Y-E answers that need with a purpose-built internal cable that converts a single MCIO x8 connector into two SFF-8639 U.2 ports with integrated power—no separate power leads, no clutter, just clean, efficient connectivity.

Who is it for

System integrators, data center technicians, and IT professionals building or upgrading servers and storage enclosures that use PCIe Gen 5 NVMe U.2 drives. This cable is ideal for compact, high-performance environments where airflow and cable management are critical.

Main features

• Connects 1x MCIO x8 host interface to 2x SFF-8639 U.2 NVMe SSDs with integrated power delivery.
• Supports PCIe Gen 5 signaling up to 32 GT/s per lane for maximum throughput.
• 45 cm length provides flexibility in rack-mount chassis without excess slack.
• Fully shielded copper conductors ensure signal integrity and reduce EMI.
• RoHS compliant construction meets environmental standards.
