SuperChassis 842TQC-668B 4U Server Chassis

This 4U rack-mountable server chassis supports ATX, EATX and Micro ATX motherboards. It includes a 668 W power supply and provides seven expansion slots. Three fans are supported for internal airflow management.

Suited for single-system rack deployments needing

The chassis offers five external 3.5 inch bays and one 5.25 inch bay for storage or media devices. It is not for builders who need redundant power supplies or hot-swap drive trays. Buyers requiring deeper cabinets for oversized cards should verify internal clearance against their components.

Deciding specification: 668 W installed power supply

The single 668 W unit powers the board, drives and add-in cards without extra cabling. If the planned load exceeds this rating, a different chassis or supply is required.

Questions about this item

What rack depth and width does the 842 chassis require for its 17.2" × 20.5" frame?

The chassis is 17.2 inches wide and 20.5 inches deep, so it fits a standard 4U rack space; verify your cabinet depth allows at least 20.5 inches plus cable clearance behind the rear panel.

How is the single installed 668 W power supply secured, and which step is often missed?

The unit ships with one 668 W supply mounted; the step often missed is locking the supply retention latch and fully seating the AC inlet before sliding the chassis into the rack.

When should the three supported cooling fans be checked or replaced?

Inspect the three fan bays every six months for dust buildup or bearing noise; replace any fan that spins slowly or rattles to maintain airflow for the 668 W supply and drive bays.
