The Seasonic PRIME PX-500 is a 500W power supply unit engineered for completely silent operation. It utilizes a fanless design with passive cooling, which eliminates all acoustic noise generated by the PSU. This model holds an 80 PLUS Platinum certification, indicating up to 92% efficiency under typical load conditions. The high efficiency level reduces waste heat, a critical factor for a passively cooled component, and lowers overall power consumption.
This PSU is constructed in a standard ATX form factor for broad compatibility with most PC cases. Its fully modular cabling system allows for the connection of only the required cables, which can improve internal airflow and simplify cable management. The unit is equipped with active Power Factor Correction (PFC) for stable power delivery. It also integrates a range of safety mechanisms, including over current, over power, over voltage, under voltage, and short circuit protections to safeguard system components.
