The OWC Accelsior 1A Apple Factory SSD to PCIe Controller Adapter Card supports transfer speeds up to 3000 MB/s. The PCIe 3.0 x4 interface enables hassle-free installation in PCIe 3.0, 2.0, and 1.0 motherboards with an available x4, x8, or x16 slot. Plus, the Accelsior 1A is bootable with compatible motherboards supporting booting via PCIe NVMe drives. OWC Accelsior 1A Apple Factory SSD Adapter LED indicator allows for easy monitoring of drive activity, and the plug-and-play design means this adapter card can be easily integrated into a machine running on Windows 10, Windows Server 2016, or Mac OS 10.13.6 or later.


This product is compatible with Apple factory SSDs that originally shipped with the Mac models listed as compatible. In addition, the following OWC SSDs are compatible: Aura Pro X2, Aura Pro X, Aura N. This product is not compatible with standard M.2 drives. AKiTiO or OWC PCIe enclosures have their own minimum system requirements which must be met when used in combination with this product. Booting support requires that your motherboard BIOS support booting via PCIe NVMe drives. Booting on Mac Pro (2010-2012) requires macOS 10.14.6. Furthermore, the data-transfer rate will vary based on SSD used, CPU capabilities, and PCIe slot used.

Expanded High Speed Storage

The Accelsior 1A is a plug-and-play solution that gives your factory SSD new life inside a 2010, 2012, 2019 Mac Pro, or Windows computer with an open PCIe slot. Alternatively, put your drive back to work externally in a PCIe expansion chassis like the OWC Mercury Helios 3S, available separately.

Fast Performance

Thanks to the PCIe 3.0 x4 interface, this adapter ensures fast performance for a range of tasks, including quick startup, app launching, and multi-stream video transfers; short render, capture, and process times in video suites like Adobe Premier, Final Cut Pro and Pro X, DaVinci Resolve, and Avid Pro Tools; quicker production capabilities in photo and audio platforms such as Adobe Photoshop, Lightroom, and Apple Logic Pro X; and faster game level loading, responsiveness, and save times.

Adaptable and Easy

Compatible with PCIe 3.0, 2.0 and 1.0 motherboards and connecting via an x4, x8, or x16 PCIe slot, the low-profile Accelsior 1A adapter card is designed for easy installation with just three steps. To get started, simply install your SSD into the Accelsior 1A connector port, then secure the SSD to the Accelsior 1A with supplied screw. Finally, install the Accelsior 1A into an open compatible PCIe slot.
