## Long description

The Chieftec Smart 350W (MPN BFX-350BS) is a compact SFX power supply unit for desktop PCs, offering 350 W total output and 80 PLUS Bronze efficiency. Its DC-DC based platform and included 90 mm fan provide a small form factor (125 × 100 × 64 mm) with active cooling while keeping noise levels low. The unit accepts AC input from 100–240 V at 47–63 Hz and includes standard connectors such as a 20+4 pin ATX motherboard cable plus SATA power cable.
Advantages
The power supply combines Bronze-level efficiency and a DC-DC design for stable voltage regulation in a compact SFX housing. A 90 mm fan is integrated without increasing the PSU length beyond 100 mm, enabling quiet cooling. Built-in protection mechanisms cover common electrical faults to protect system components.
Suitable for
Small form factor desktop builds where space is limited
Basic home and office PCs requiring reliable 350 W power
Systems using standard ATX motherboards with 20+4 pin connectors
