Mid-tower server chassis with 668W supply

The Supermicro CSE-733TQ-668B is a mid-tower server chassis that includes a 668W power supply. It fits 12" x 13" E-ATX and ATX motherboards and provides four 3.5" hot-swap drive bays with SGPIO support. Seven full-height expansion slots accommodate add-in cards for storage or networking. This unit targets small-business servers or workstation builds needing direct drive access.

Check motherboard size and drive interface

Verify that your motherboard measures no larger than 12" x 13" to fit the E-ATX mounting pattern. Confirm that your drives use SAS or SATA interfaces, as the backplane does not support other protocols. Ensure your power cables reach the 668W supply location and that the seven expansion slots align with your card bracket heights. Front USB 2.0 headers must be present on the board for the two front ports.

Steel construction with lockable door and PWM

The black steel chassis weighs 38.00 lbs and measures 16.80" x 7.00" x 20.90", giving a rigid frame for rack or desk placement. A lockable front door secures the four hot-swap bays against accidental ejection. One 12cm rear fan spins at 4000 rpm and one 9cm front fan at 4200 rpm, both PWM controlled for automatic speed adjustment. Drive trays slide in tool-free, and the SGPIO backplane reports status to compatible controllers.

Questions about this item

What comes in the box with the CSE-733TQ-668B and what must I add?

The chassis includes a 668 W power supply, a 4-bay 3.5" SAS/SATA hot-swap backplane with SGPIO, one 12 cm rear PWM fan at 4000 rpm and one 9 cm front PWM fan at 4200 rpm. You must supply an E-ATX or ATX motherboard (12" x 13"), CPU, memory, drives and an operating system.

Which capacity of the 3.5" hot-swap bays should I choose for my storage needs?

The unit provides exactly four 3.5" hot-swap bays supporting SAS or SATA drives with SGPIO. Choose this version if you need four bays; there is no other bay-count option for this model.

What does the 668 W rating mean once the system is built?

The 668 W supply powers the motherboard, up to four 3.5" drives, add-in cards in seven full-height slots and the two included PWM fans. Total continuous draw of all installed components must stay below 668 W.
