Boost. Expand. Maximize.

If you’re looking to upgrade your desktop machine’s performance, build a custom system, or expand a server’s capabilities, the Accelsior 1M2 is the cost-effective solution. This x4 PCIe M.2 SSD adapter card lets you add your choice of M-Key M.2 PCIe SSD to increase the speed and storage/backup capacity of your 2019 Mac Pro, 2012 and 2010 Mac Pro, or PC tower and enjoy:
  • Near instant start-up and business critical app launching
  • Real-time processing of intensive transfer tasks like multi-stream video editing
  • Shorter render, capture, and process times in video suites like Adobe Premier, Final Cut Pro/Pro X, DaVinci Resolve, and Avid Pro Tools
  • Quicker production capabilities in photo and audio platforms like Adobe Photoshop, Lightroom, and Apple Logic Pro X
  • Faster game level-loading, responsiveness, and save times
  • More years of productive use from your machine

Low Frills…High Thrills

When your primary upgrade goal is to make your machine as fast as possible with maximum cost effectiveness, the Accelsior 1M2 adapter card is the answer. It was designed with one, no-frills purpose: utilize an open PCIe slot to deliver the thrilling speed advantage of an M.2 PCIe SSD like the OWC Aura Ultra III. No RAID decisions, no set-up hassle, no SATA bottleneck…just add your own drive to this card for pure unadulterated storage performance that can’t be beat.

Perfect Inside or Out

By supporting PCIe 4.0/3.0/2.0/1.0 motherboards and able to plug into x4/x8/x16 PCIe slots, the Accelsior 1M2 adapter card is a perfect performance upgrade for a wide variety of full-sized and small form factor computers.
If your Mac/PC doesn’t have an open or compatible PCIe slot but is Thunderbolt 3 compatible, the Accelsior 1M2 adapter card can be used externally in a PCIe Expansion chassis like the OWC Mercury Helios 3S (sold separately).

Adaptable and Easy

The Accelsior 1M2 adapter card transforms into a storage solution in three easy steps:
  • Insert your choice of PCIe SSD, from an M.2 AHCI to the latest high-speed M.2 NVMe, into the Accelsior 1M2 adapter card’s connector port.
  • Secure the SSD to the Accelsior 1M2 adapter card with supplied screw.
  • Install the Accelsior 1M2 adapter card into an open PCIe slot inside your computer.
  1. Performance will vary depending on SSD used, CPU speed, and PCIe version.
  2. Performance in a Thunderbolt 3 PCIe expansion chassis limited by maximum Thunderbolt 3 PCIe bandwidth of 2,800MB/s.
  3. Select drives may disable the LED function of this product.

    May old 2009 Mac Pro

    At first I did not know how it worked. I did not realize that the 1 TB card was part of this item so I thought I needed to order a 1TB card. I did then I realized I did not need it and I had to return this to you. Other wise it works great.

    I would recommend this product to a friend!

    Thank you so much for your fantastic review! We're thrilled to hear that your 2009 Mac Pro is working great with our product. We understand that the initial confusion about the 1TB card can happen, and we appreciate your willingness to return the extra one. Your feedback is invaluable, and we're always here to help you get the most out of your purchases. Enjoy your upgraded Mac experience!


    Simple yet perfect product

    I bought two of those for my 2019 Mac Pro (MacPro7,1). One, crucially, was for the installation of Windows, which is always a cumbersome and dicey proposition on all Apple hardware at the best of times. The OWC Accelsior has facilitated the job beautifully: Windows Setup had no problem with Accelsior, and Windows 11 boots up — and runs — from the PCIe NVMe SSD perfectly. I wholeheartedly recommend the product: It is decidedly solid and a good value for money.

    I would recommend this product to a friend!
