Chieftec BFX-450BS 450W - PSU, 80 Plus Bronze

The Chieftec BFX-450BS is a power supply unit designed to deliver 450W of continuous power within a compact SFX form factor. Its design is specifically suited for small-footprint system builds where space is a primary consideration. The unit operates with 80 PLUS Bronze certified efficiency, which helps reduce wasted heat and energy consumption under typical workloads. To ensure consistent power delivery, it incorporates DC-to-DC converter technology for stable voltage regulation across the main power rails.

Thermal management is handled by a 90 mm fan equipped with automatic fan speed control, which adjusts its rotational speed to balance cooling effectiveness and acoustic output. This model features a non-modular cable configuration, providing a fixed set of essential connectors for system components like the motherboard, CPU, and graphics card. A comprehensive suite of protection mechanisms is integrated, including overvoltage, overload, and short circuit protection, to safeguard the hardware from potential electrical faults.
