Description
🔌 ESSENTIAL CABLE FOR U.2/U.3 NVMe STORAGE
Professional-grade 50cm Oculink to U.2 cable – often sold separately for £30-40
High-Quality Oculink to U.2/U.3 Connection Cable
This 50cm Oculink SFF-8611 to U.2 SFF-8639 cable is an essential component for connecting U.2 or U.3 NVMe SSDs to systems with Oculink ports. Whether you’re using a PCIe to Oculink adapter card, an M.2 to Oculink adapter, or a motherboard with built-in Oculink connectors, this cable provides the reliable connection you need for high-performance enterprise storage.
Why You Need This Cable
🔧 With Adapter Cards
Required to connect PCIe to Oculink adapter cards to your U.2/U.3 NVMe SSD. Many adapters are sold without cables, requiring separate purchase.
💾 Replacement Cable
Replace a lost, damaged, or worn cable from your existing U.2 adapter kit. Keep a spare for mission-critical systems.
📏 Extension/Flexibility
50cm length provides installation flexibility, allowing you to position U.2 SSDs in optimal locations for cooling and cable management.
🖥️ Motherboard Oculink
Some workstation and server motherboards have native Oculink ports. This cable connects them directly to U.2/U.3 drives.
