Supermicro CSE-747BTQ-R2K04B 4U server chassis

4U Server Chassis with 2000W Titanium PSU

The Supermicro CSE-747BTQ-R2K04B is a 4U rackmount chassis that includes a redundant 2000W Titanium-certified power supply. It supports E-ATX motherboards up to 15.2 by 13.2 inches and provides eleven full-height expansion slots. Eight hot-swappable 3.5-inch drive bays connect through a SAS/SATA backplane with SES2 support. Three 5.25-inch external bays and two front USB 3.0 ports complete the front I/O.

Suited for GPU compute and dense storage.

This chassis targets workloads that need up to four double-width GPUs alongside eight removable hard drives. The eleven-slot layout and middle 92mm PWM fans plus rear 80mm PWM fans deliver airflow for sustained high-power operation. Lockable front door and side intrusion switch add physical security for multi-tenant racks. Builds needing a smaller form factor, fewer expansion slots, or a non-redundant power supply should consider other platforms.

Eight-bay SAS/SATA backplane with SES2 monitoring

The single specification that decides fit is the eight-drive hot-swap backplane supporting SAS and SATA drives with SES2 enclosure management. It determines whether your storage topology matches the chassis before you commit to the 4U footprint and 2000W redundant power budget.
