The CHIEFTEC CSN-650C is an SFX power supply unit designed for small form factor systems that require stable and efficient power. It delivers a continuous output of 650 watts and holds an 80 PLUS Gold certification, indicating up to 90% efficiency under typical loads. This level of efficiency helps to reduce waste heat and overall energy consumption within a compact chassis. The unit incorporates Active Power Factor Correction (PFC) to ensure consistent power delivery to critical components and complies with the ATX12V 2.3 standard for broad compatibility.
This PSU features a fully modular cabling system, allowing users to connect only the necessary cables for a cleaner build and improved internal airflow. Cooling is managed by an 80 mm fan designed to balance thermal performance with acoustic output. A comprehensive suite of protection circuits is integrated, including over-current, over-voltage, and short-circuit protection, to safeguard the system's hardware. The unit's compact dimensions make it suitable for installation in space-constrained PC cases without compromising on power or connectivity options.
