Product information

Description

The Chieftec EON ZPU-400S 400W 20+4 pin ATX Black is a compact ATX power supply designed for desktop PCs and small servers. It provides up to 400 W of continuous output, supports AC input of 200–240 V at 50 Hz and uses a 20+4 pin motherboard connector for compatibility with a wide range of systems. The unit is 80 PLUS certified for energy efficiency, housed in a steel chassis coated in black, and cooled by a 120 mm fan for quieter operation.

Advantages

The EON ZPU-400S offers a balance of efficiency and basic protection features suitable for mainstream systems. Its 80 PLUS certification helps reduce wasted power and heat compared with non-certified units, while the native 20+4 pin connector ensures straightforward installation on older and newer motherboards alike. The steel construction and black finish provide durable protection and a neutral appearance that fits most builds. The 120 mm fan delivers cooling with lower noise under typical loads.

How to use

Install the Chieftec EON ZPU-400S into a compatible ATX case following standard safety procedures: disconnect mains power, ground yourself to avoid static discharge, and mount the unit securely to the case with the supplied screws. Connect the 20+4 pin ATX cable to the motherboard main power socket and attach required peripheral connectors to drives and other components.
