Product information

Description

CHIEFTEC APB-400B8 is a 400 W ATX power supply unit designed for desktop PCs and compact servers. It operates on 200–240 V AC (47–63 Hz) and includes a 20+4 pin ATX motherboard connector, a single 120 mm cooling fan and PS/2 form factor housing. The unit carries 80 PLUS (230V EU) efficiency certification and comes in a silver finish. Native cable lengths include a 35 cm motherboard cable and SATA power cables of 150 mm and 350 mm, providing compatibility with common PC layouts.

Advantages

The APB-400B8 offers a balance of functional efficiency and basic connectivity for standard systems. Its 80 PLUS 230V EU certification indicates improved energy use under typical European mains conditions, while the integrated 120 mm fan and thermal control board help maintain stable cooling and lower acoustic output under load. The 20+4 pin ATX connector and several native power leads simplify installation in a wide range of cases and server chassis. Certified by multiple safety and compliance bodies, the unit meets common regulatory requirements.

Suitable for

Entry-level and office desktop PCs needing reliable 400 W power delivery
Compact home servers or NAS builds that fit PS/2 form factor units
Systems requiring a straightforward ATX power connector and basic SATA power distribution
Builds where moderate efficiency (80 PLUS 230V EU) and quiet fan operation are desirable

How to use

Install the CHIEFTEC APB-400B8 into a compatible chassis that supports PS/2 form factor power supplies or an ATX mounting layout. Secure the unit with the appropriate screws, connect the 20+4 pin ATX cable to the motherboard main power socket, and attach SATA power connectors to storage devices as required. Ensure the mains switch (if present) is off when making connections, then connect to a 200–240 V AC supply and switch on. Verify system POST and stable operation under expected load before closing the case.

Usage recommendations

For reliable operation, use the PSU within its rated 400 W capacity and avoid overloading combined rails. Keep intake and exhaust airflow unobstructed, maintain ambient temperature within typical PC room ranges, and periodically check cables and connectors for secure seating. For system upgrades that significantly increase power draw (more powerful CPU, multiple GPUs, or many drives), evaluate a higher-wattage or higher-efficiency unit.
