Server Chassis Supermicro SuperChassis 523L-505B 2U Black

The Supermicro SuperChassis 523L-505B is a compact 2U server chassis engineered for space-constrained installations. With a depth of only 369 mm (14.5"), the black chassis provides front I/O accessibility and supports both 2.5" and 3.5" drives. It includes a 500 W high-efficiency power supply and accepts ATX motherboards, delivering a balance of performance and efficient cooling in a small footprint.

Advantages

The chassis combines a shallow 369 mm depth for rack locations with limited clearance and multiple drive bay options (two 3.5" and four 2.5") to accommodate varied storage configurations. Front I/O ports enable convenient access, and the included 500 W power supply offers efficient, stable power delivery. Interior layout is optimized to maintain effective airflow and component cooling despite the compact dimensions.

Suitable for

• Small to medium data centers with limited rack depth
• Edge or branch office servers where space is constrained
• Storage-focused builds requiring mixed 2.5" and 3.5" drives
• ATX-based server systems in a 2U form factor

Key specifications

• Form factor: 2U
• Dimensions (W x D x H): 426 mm x 369 mm x 86 mm
• Drive bays: 2 × 3.5" and 4 × 2.5"
• Power supply: 500 W (included)
• Supported motherboard: ATX
• Color: Black

How to use

Install an ATX motherboard and populate drive bays according to your storage needs using the provided mounting points. Connect front I/O and power supply cabling to the motherboard headers and route cables to preserve airflow. Mount the chassis into a compatible 2U rack space of at least 369 mm depth, secure it with rack screws, and verify power and fan operation before commissioning.

Recommendations

For reliable cooling and longevity, leave adequate rack ventilation around the chassis, avoid obstructing front intake ports, and use drives and components within the chassis' specified power and thermal limits.
