## Long description

The BFX Series power supply combines 80 PLUS Bronze efficiency with a modern DC-DC platform in a compact SFX form factor. Designed with a 9 cm cooling fan while keeping the total unit length to 10 cm, the BFX Series provides a small footprint suitable for compact PC builds without sacrificing essential functionality or protection features.
Advantages
The compact SFX design allows installation in small chassis where space is limited. 80 PLUS Bronze efficiency helps reduce energy loss and operating costs during typical use. DC-DC conversion improves voltage stability and compatibility with modern components. The included 9 cm fan supports quieter operation compared with larger, faster-spinning fans, while built-in protection mechanisms guard against common electrical faults.

How to use
Install the BFX Series power supply into an SFX-compatible chassis following the case manufacturer’s mounting instructions. Connect the main ATX and peripheral cables to the motherboard, drives and other components according to their connectors, ensuring secure and correct seating. Verify that the case airflow is adequate for the 9 cm fan to expel heat effectively, and perform a power-on test before full system use.
