Reviewer: PhotoStudio
Rating: 5/5 Great power supply July 6, 2021 After years of service a power supply died to one of our 14 OWC external drives. A quick search at macsales to find and purchase the replacement. At a reasonable price point. The power supply arrived a few days later. Drive back online; couldn’t have been simpler.

I would recommend this item to a friend!
