  • Connects U.2 NVMe SSDs via PCIe 3.0 x4 slot
  • Supports Intel SSD 750 M.2 drives with SFF-8654 interface
  • Converts SFF-8639 to SFF-8654 Slimline SAS for NVMe only
  • Includes PCIe card and standard bracket for mainboard installation
  • Hyper Kit storage controller enables high-speed PCIe SSD connectivity

PCI-E 3.0 x4 Adapter for U.2 NVMe SSDs

This adapter connects a U.2 NVMe SSD to a motherboard using a PCI-E 3.0 x4 slot. It uses SFF-8639 to SFF-8654 Slimline SAS connectors to bridge the interface. The kit includes the card and a standard bracket for installation. It is designed for builders adding high-speed PCIe storage to a desktop system.

Sustained PCIe 3.0 x4 Link Performance

The card operates over a PCIe 3.0 x4 electrical link, providing consistent bandwidth for the attached NVMe SSD. Because it is a passive adapter without a controller, drive performance scales directly with the host slot and SSD capabilities. Thermal behaviour depends on the drive and case airflow, not on the adapter itself. No active cooling or power management features are present on the board.

Passive Build with Slimline SAS Connectors

The printed circuit board carries only signal traces between the PCIe edge connector and the SFF-8654 Slimline SAS port. A standard bracket secures the card to the chassis for stable mounting. The SFF-8639 U.2 drive connects via a separate cable assembly not included in the kit. This passive design adds no latency, but requires the host platform to support NVMe over the PCIe slot.

Questions about this item

How much heat or power does the PCIe 3.0 x4 adapter add when running an NVME SSD all day?

The adapter itself is a passive board with no active cooling; it draws negligible power beyond the PCIe 3.0 x4 slot and adds no measurable heat to the system.

What must my motherboard provide for this card to work with a U.2 NVME drive?

A free PCIe 3.0 x4 slot and a motherboard that supports NVME boot or storage devices; the kit includes the card and a standard bracket.

Will the adapter work with my older Intel SSD 750 that uses the SFF-8654 Slimline SAS connector?

Yes, the card is designed for that SSD and converts the SFF-8639 U.2 interface to the SFF-8654 Slimline SAS connection used by the Intel SSD 750.
