Virtalähde CHIEFTEC PSF-400B 400W ATX 2.3, 80 PLUS Bronze, 24-Pin, 80 mm tuuletin

The PSF-400B power supply combines a traditional ATX-like layout with modern compatibility, certified by TÜV and meeting ENERGY STAR 5.0 requirements. Designed for fixed 230V European mains, it is intended for reliable, efficient operation in contemporary IT environments and industrial PC installations.

Advantages

The PSF-400B supports current power-supply standards while preserving a familiar layout, provides TÜV certification for safety and compliance, and meets ENERGY STAR 5.0 efficiency criteria. Its fixed 230V configuration simplifies deployment in European systems. The cooling fan is engineered to exhaust air to the rear, which is suitable for compact 19” IPC/UNC chassis with limited height.

Key specifications

• Model: PSF-400B
• Input voltage: fixed 230V (European standard)
• Certifications: TÜV; ENERGY STAR 5.0 compliant
• Form factor compatibility: suitable for 19” IPC / UNC solutions (2U–4U)
• Cooling: fan configured to blow air out the rear

How to use

Install the PSF-400B in 19” IPC/UNC chassis with 2U to 4U height where rear exhaust is required. Connect to a stable 230V mains supply and follow the chassis manufacturer’s installation instructions to secure the PSU and route cables. Ensure the rear airflow path is unobstructed to maintain cooling performance.

Recommendations

Use the PSF-400B in rack-mounted or embedded systems where the PSU position is constrained vertically and rear exhaust is necessary; verify chassis compatibility and provide adequate ventilation around the rear exhaust port.
