U.2 NVMe PCIe Adapter
The StarTech PEX4SFF8639 is a PCI Express 3.0 x4 expansion card that lets you install a single 2.5in U.2 NVMe SSD into any desktop or server with a free PCIe slot. It targets system builders and IT professionals who need enterprise-grade U.2 storage without a dedicated backplane or drive bay.
Fixed Mount, Direct Connection
The card holds the SSD in a fixed position using the included screws, supporting drive heights of 5mm, 7mm, 9.5mm, 12.5mm and 15mm. This design removes the need for separate adapter cables, simplifying cable routing inside the chassis and reducing potential connection points.
Passive Thermal Design
With no onboard fan or active cooling, the adapter relies entirely on case airflow to manage SSD temperatures. Power draw is limited to the drive itself, adding negligible load to the PCIe slot and keeping acoustic output at zero during normal operation.

이 상품에 대한 질문
What PCIe version and lane width does the PEX4SFF8639 use, and what throughput does that cap at?
The card runs at PCIe 3.0 x4, so the drive is limited to the bandwidth of a 3.0 x4 link.
Which drive heights and screw pattern does the adapter accept for a 2.5in U.2 SSD?
It supports 5mm, 7mm, 9.5mm, 12.5mm and 15mm drives and includes four mounting screws for the fixed installation.
How is the SSD attached to the card, and what step is often missed during installation?
The drive mounts directly onto the adapter with the supplied screws; a common mistake is leaving the drive unsecured before seating the card in the PCIe slot.
