PCIe x4 to U.2 NVMe SSD Adapter Card with Cable — SFF-8643 to SFF-8639 Kit

Description

Use Enterprise U.2 NVMe SSDs in Any Desktop or Server

The IO Crest IO-PCE4X-U2 adapter card converts a standard PCIe x4 slot into an SFF-8643 (Mini SAS HD) port, letting you connect high-capacity 2.5″ U.2 NVMe SSDs to any desktop PC, workstation or server.

Enterprise U.2 NVMe drives like the Intel P4510 and Samsung PM983 are available secondhand at a fraction of the cost of consumer M.2 SSDs — often under £50 for 2TB or more. This adapter is the bridge that makes them usable in standard systems.

Complete Kit — Cable Included

Unlike most competitors (including StarTech), this kit includes the SFF-8643 to SFF-8639 cable with integrated SATA power connector. That’s everything you need to connect a U.2 drive — no separate cable purchase required, saving you £10-15 versus buying the adapter and cable separately.

• IO Crest IO-PCE4X-U2 PCIe adapter card (full height bracket pre-installed)

Important Compatibility Notes

• NVMe drives only — does not support SAS or SATA drives
• SATA power required from PSU via the included cable
• Requires PCIe x4 slot minimum (works in x8 or x16 slots)
• UEFI 2.3.1+ recommended for boot support; older BIOS systems can use the drive as secondary storage
• Does not support hot-swap — power off before connecting or disconnecting
