Product information

Description

The StarTech.com PEX4SFF8643 adapter adds enterprise-class 2.5" PCIe U.2 NVMe SSD support to a desktop PC or server that lacks native U.2 connectivity. The compact, red expansion card provides a PCIe host interface and an SFF-8643 U.2 output, enabling connection of U.2 NVMe drives (for example Intel® SSD 750 series) through an SFF-8643 to U.2 cable. The card is compatible with PCIe 3.0 and PCIe 2.0 slots and ships with both a full-height bracket (preinstalled) and a low-profile bracket for small form-factor systems.

Advantages

This adapter enables cost-effective upgrades by allowing installation of modern U.2 NVMe SSDs into existing motherboards without native U.2 support, improving read/write performance and energy efficiency compared to SATA-based storage. It supports installation in any 4-lane (or greater) PCI Express slot and is compatible with common server and desktop systems. The included full- and low-profile brackets provide flexible mounting options, and the adapter is backed by a 2-year StarTech.com warranty and free lifetime technical support.

Suitable for

Upgrading legacy desktops and servers to support U.2 NVMe SSDs
Workstations and data-center machines requiring higher I/O performance
System integrators and IT professionals performing hardware upgrades
Small form-factor PCs where a low-profile bracket is needed

Key specifications

Host interface: PCIe (x4, requires a 4-lane or greater PCI Express slot)
Output interface: SFF-8643 (for U.2 NVMe SSD connection via SFF-8643 to U.2 cable)
PCIe compatibility: PCIe 3.0 and PCIe 2.0
Form factor: full-height (preinstalled) and included low-profile bracket
Dimensions (W x D x H): 18 mm x 81 mm x 44 mm
Weight: 0.038 kg
Product colour: Red
Manufacturer part number (MPN): PEX4SFF8643
Warranty: 2 years (StarTech.com)

How to use

Install the adapter into an available 4-lane (or greater) PCIe slot on the desktop PC or server. Select and attach the appropriate bracket (full-height or low-profile) before mounting the card. Connect the U.2 NVMe SSD to the adapter using an SFF-8643 to U.2 cable, then secure the drive according to your chassis and drive manufacturer instructions. After installation, verify that the system BIOS/firmware recognizes the NVMe drive and install any required drivers or OS updates to enable NVMe support.

Usage recommendations

For best performance, install the adapter in a PCIe 3.0 x4 slot and use U.2 NVMe SSDs that meet your workload requirements. Ensure adequate airflow and cooling in the case when deploying enterprise NVMe drives, and confirm motherboard BIOS support for NVMe devices before installation.
