Thermaltake Smart BX3 550W - PSU, 80 Plus Bronze

The Thermaltake Smart BX3 is a 550W power supply designed for ATX-based systems, compliant with the ATX 3.1 standard for compatibility with current hardware. It features an 80 PLUS Bronze certification, indicating its operational efficiency under typical loads. The unit utilizes a non-modular cabling design, where all cables are permanently attached, which is a key consideration for system builders planning their internal layout and airflow. Integrated Active Power Factor Correction (PFC) helps to regulate voltage and improve power delivery stability from the source.

Thermal management is handled by a single 120mm fan controlled by a Smart Zero Fan function. This feature prevents the fan from spinning at low to moderate power draws, minimizing acoustic output during idle or light usage periods. The power supply is built with a suite of protections, including OCP, OVP, UVP, OPP, OTP, and SCP, to safeguard system components against electrical anomalies. With standard ATX dimensions of 150mm x 86mm x 140mm, it is designed for straightforward installation in compatible chassis.
