Server Chassis Supermicro SuperChassis 842TQC-668B Rack Black, Grey

The Supermicro SuperChassis 842TQC-668B is a rack server chassis designed for high-density server deployments. It supports Micro ATX, ATX and EATX motherboards, accepts five 3.5" drive bays and three 5.25" bays, and includes a 668 W power supply with wide 100–240 V AC input. With a compact footprint (437 mm W × 521 mm D × 178 mm H) and a grey-and-black finish, the chassis is suitable for standard rack installations and varied server configurations.

Advantages

The chassis offers a system-level optimized design with support for SAS3 12 Gb/s and NVMe devices, and is compatible with recent x86 platforms. It features optimized thermal design for improved cooling and lower power consumption, high-efficiency power delivery up to Titanium level, hot-swappable redundant components (power supplies, fans, drive trays), and components chosen for reliability and serviceability. These characteristics provide scalability, adaptability and high availability for professional server environments.

Suitable for

• Rack-mounted database and application servers
• Storage servers using multiple 3.5" drives
• Virtualization hosts and compute nodes
• Enterprise backup and archive systems

How to use

Install the appropriate motherboard (Micro ATX, ATX or EATX) into the chassis standoffs, secure drives into the 3.5" bays or 5.25" bays as required, and connect power and data cables to the drives and motherboard. Mount the chassis into a standard rack using the front mounting ears or rails according to rack unit spacing. Configure cooling by installing required fans and setting fan speed controls if available; connect the included 668 W power supply to a compatible AC source (100–240 V, 50–60 Hz). For hot-swap components, follow safe removal and insertion procedures while maintaining redundant power or shutting down as appropriate.

Recommendations

For reliable operation, use enterprise-class 3.5" drives and set up redundant power and fan configurations. Ensure sufficient rack ventilation and airflow by following the chassis airflow guidelines and verifying that installed components (e.g., high-TDP CPUs, NVMe devices) have adequate cooling. Regularly check firmware and power-supply health to maintain availability.
