4U Tower Chassis with Redundant Power

The Supermicro CSE-745BAC-R1K23B-SQ is a 4U tower chassis designed for server deployments that need high storage density and reliable power. It supports motherboards up to E-ATX 13.68" x 13" and includes a 1200W 1+1 redundant Titanium-level power supply. Eight hot-swap bays accept 3.5" or 2.5" SAS and SATA drives.

Suited for Storage-Focused Servers

This chassis suits builders who need eight hot-swap bays, redundant power, and quiet operation in a tower form factor. The front door lock and intrusion switch add physical security for shared environments. It is not for systems requiring more than eight hot-swap bays or 5.25" devices beyond the three external bays provided.

1200W 1+1 Redundant Titanium Power Supply

The included 1200W redundant power supply carries Titanium-level efficiency certification, delivering high-efficiency power with failover protection. This single specification decides whether the chassis meets the uptime and efficiency requirements of the target deployment.
