The CHIEFTEC PROTON BDF-850C is an ATX power supply unit with a total power output of 850 watts. It is designed for systems with high power demands and utilizes DC-to-DC conversion technology to maintain stable voltage regulation for connected components. The unit has an 80 PLUS Bronze certification, which corresponds to an operational efficiency of up to 85% under typical workloads. This design prioritizes consistent power delivery while reducing energy loss as heat.
This power supply features a fully modular cabling system, which allows for the connection of only the necessary cables for a specific build. This approach can help improve internal case airflow and simplify cable management. Cooling is managed by a single 140mm fan that supports a silent mode for reduced acoustic output during low-load scenarios. The unit is built within a standard ATX chassis measuring 140mm in depth and is equipped with a suite of protection features, including over voltage, overload, and short circuit protection.
