Supermicro CSE-745BAC-R1K23B 4U Tower Server Chassis

4U Tower Server Chassis with Redundant Power

The Supermicro CSE-745BAC-R1K23B is a 4U tower chassis that supports dual or single Intel and AMD processors. It provides seven full-height, full-length PCI Express expansion slots for add-in cards. A 1230W 1+1 redundant Titanium-certified power supply is included for high-efficiency operation. Front I/O includes two USB 3.0 ports for local access.

Suited for Storage-Dense Builds.

This chassis suits builders who need eight hot-swap 3.5 or 2.5-inch SAS drive bays with SES3 monitoring and three external 5.25-inch bays. The lockable front door and side-panel intrusion switch add physical security for shared environments. Five 8cm PWM fans at 9400 rpm deliver directed airflow across drives and expansion cards. Buyers needing a rackmount form factor or a smaller footprint should consider other chassis types.

Eight Hot-Swap SAS Drive Bays with SES3

The backplane accepts eight 3.5-inch or 2.5-inch SAS drives in hot-swap trays and reports enclosure status through SES3. This single specification determines whether the chassis matches a storage-heavy server design. Maximum motherboard support extends to E-ATX at 13.68 by 13 inches alongside ATX and Micro-ATX. Overall dimensions are 17.80 by 7.00 by 25.50 inches with a weight of 59.00 pounds.
