Power supply unit CHIEFTEC SFX-250VS 250 W 20+4 pin ATX SFX Silver, 80 mm fan, non-modular

CHIEFTEC SFX-250VS is a compact SFX power supply unit that delivers 250 W of continuous power with 85% efficiency, intended for small form-factor PCs and basic desktop builds. The unit uses a 20+4 pin ATX motherboard connector, features a single 80 mm fan mounted in a silver housing and provides standard protection functions including undervoltage, overvoltage, short-circuit and overcurrent/overpower safeguards. Its design focuses on reliable, quiet operation for home and office systems running on 230 V/50 Hz mains.

Advantages

The small SFX footprint and non-modular cabling make the CHIEFTEC SFX-250VS straightforward to install in compact cases where space is limited. The 80 mm fan is engineered for low acoustic output, enabling near-silent operation during everyday tasks. Built-in protection features (UVP, OVP, SCP, OPP, AFC) and stable 230 V/50 Hz compatibility support safe and consistent power delivery for basic computing needs.

Suitable for

• Small form-factor (SFX) desktop builds
• Home and office PCs with modest power requirements
• Systems where low fan noise is preferred
• Replacement PSU in compact cases

Connect the 20+4 pin ATX plug to the motherboard main power socket and attach other required peripheral connectors for drives or accessories. Ensure the unit is secured and that cables are routed to avoid obstructing airflow. Verify mains voltage is set to 230 V if an external selector exists and power on the system to confirm stable operation.

Recommendations

Use this PSU in systems with modest power draw; avoid pairing it with high-power graphics cards or multiple power-hungry components. Maintain case airflow and periodically check the 80 mm fan for dust accumulation to preserve quiet operation and cooling efficiency.
