3U server chassis with redundant 920W PSU

This 3U rackmount chassis accepts E-ATX and ATX motherboards and ships with a 1U 920W redundant Platinum power supply featuring PMbus monitoring. Eight 3.5" hot-swap bays support SAS and SATA drives, while two 5.25" bays remain available for optical or auxiliary devices. Seven full-height, full-length expansion slots provide room for multiple add-in cards.

Hot-swap drive cage and cooling layout

The backplane uses the SAS833/835 design with an AMI MG9072 controller, allowing drive replacement without tools or downtime. Three 80mm hot-swap PWM fans at the front and two 80mm rear hot-swap exhaust PWM fans maintain airflow and can be swapped while the system runs. Redundant power modules and fan trays are all accessible from the front or rear for simplified service.

Verify motherboard and rail compatibility

Confirm that your E-ATX or ATX board fits the 3U mounting pattern and that the seven expansion slots align with your card layout. Ensure the rack depth can accommodate the chassis and that the 920W redundant supply meets the total power draw of your planned components. Buyers needing 2.5" drive support or front USB 3.0 ports should look elsewhere.
