CHIEFTEC SMART SERIES PSF-400B 400W - PSU, 80 Plus Bronze

The CHIEFTEC PSF-400B is an ATX power supply unit delivering a total power output of 400 watts. It is specifically engineered for use in 19-inch IPC and UNC server chassis, particularly in 2U to 4U configurations where height restrictions require a rear-exhaust cooling layout. The unit is 80 PLUS Bronze certified, signifying an efficiency level of up to 87% under typical operational loads. It incorporates Active Power Factor Correction (PFC) to maintain stable and efficient power delivery from the mains.

Cooling is managed by a single 80mm fan that directs airflow out the back of the power supply, a design choice suited for compact server builds. The PSU features a non-modular cabling system, with all wires permanently attached to the main housing. For system integrity, it includes essential power protection features against overload and short circuits. With a Mean Time Between Failures (MTBF) of 100,000 hours, the unit is constructed for long-term operation in its intended environments and meets ENERGY STAR 5.0 compliance standards.
