The TFX Power 3 is a 300W power supply unit designed for compact PC builds, such as mini or media systems, that require the TFX form factor. It delivers stable and continuous power with an 80 PLUS Gold certification, indicating an operational efficiency of up to 91.7%. This high efficiency rating results in lower energy consumption and less waste heat, which is a key consideration for small, space-constrained enclosures with limited airflow. The unit is built to provide consistent performance for hardware components within its power rating.
This PSU is equipped with a temperature-controlled 80mm fan that automatically adjusts its speed to provide necessary cooling while maintaining low noise levels. It includes a single 6+2 pin PCIe connector, enabling the installation of a compatible graphics card. The cables are sleeved for a clean internal appearance and are non-modular, simplifying the installation process. A comprehensive suite of safety features, including Over Current Protection (OCP) and Over Voltage Protection (OVP), is integrated to safeguard system components against electrical irregularities.
