Product information

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

How to use

Install the Chieftec Smart 350W into an SFX-compatible PSU bay following your PC case manual. Connect the 20+4 pin ATX cable to the motherboard and route the SATA and other peripheral cables to drives and accessories. Ensure the AC mains connection matches the 100–240 V input range and switch on the system. Verify stable operation and normal fan function during initial power-up.

Usage recommendations

Use this PSU in systems whose total power draw does not exceed 350 W and where Bronze efficiency and compact size are appropriate. Keep ventilation unobstructed around the 90 mm fan and avoid placing the unit in excessively dusty environments.
