Buffalo Replacement Power Supply for TeraStation 51210RH

The Buffalo OP-PU-10R2UWR is an internal replacement power supply made for the TeraStation 51210RH rackmount NAS. It gives you a straightforward way to keep your storage array powered when the original unit reaches the end of its service life or when you want a second supply for redundancy. Because it slides directly into the chassis, there is no need for external power bricks or extra cabling, so your rack stays tidy and easy to manage.

Buffalo chose an industrial grade design for this supply, which helps the TeraStation maintain reliable operation in offices, production studios, or server rooms that run around the clock. The unit supports hot-plug installation, allowing you to swap it without taking the NAS offline. That benefit is essential for businesses that cannot tolerate downtime, whether you are hosting virtual machines, managing surveillance footage, or sharing large creative files.

The power supply measures 6.9 by 3.2 by 1.6 inches and weighs 6.7 pounds, so it fits cleanly into the existing bay without affecting airflow or rack layout. It works with every factory configuration of the TeraStation 51210RH, from 16 TB up to 96 TB, and it remains covered under the original TeraStation warranty when purchased with the main unit.
