Product information

Description

The Inter-Tech Coba CES-400B 400 W is a bulk-packaged power supply unit engineered for assemblers and system builders. It focuses on technical performance rather than retail packaging, offering a compact design with a super-silent 120 mm fan, multiple connectors including P4+4 and PCI-Express, and two separate 12 V rails. The unit is 80 PLUS Bronze certified, which ensures higher efficiency and reduced energy loss.

Advantages

The CES-400B reduces costs by being supplied as a bulk product while prioritizing technical features such as efficient 80 PLUS Bronze performance, low-noise cooling from the 120 mm fan, and a variety of connectors for compatibility with common PC components. Two separate 12 V lines contribute to stable power distribution for multi-rail setups.

Suitable for

Home and office desktop PCs
System builders and assembler projects
Mid-range gaming or multimedia systems with standard graphics cards
Upgrades where a reliable 400 W PSU is required

Motherboard connector: 20+4 pin ATX
80 PLUS certification: 80 PLUS Bronze
Fan diameter: 120 mm
Input voltage: 115 - 230 V AC

How to use

Install the Inter-Tech Coba CES-400B into a compatible PC case following standard ATX PSU mounting procedures. Connect the 20+4 pin ATX connector to the motherboard, attach the required P4+4 and PCI-Express connectors to CPU and GPU as needed, and connect storage and peripheral power cables. Ensure the input voltage selector or automatic switching matches your mains supply (115–230 V). Power on the system and verify stable operation and fan activity.

Usage recommendations

For reliable operation, use the CES-400B in systems whose total power draw stays below the unit's 400 W rating. Keep ventilation clear around the 120 mm fan, install the PSU in a case with adequate airflow, and ensure connectors are firmly seated. Bulk packaging means fewer accessories may be included—verify included cables before installation.
