SEASONIC source Prime PX-500 Fanless Platinum ATX3.1 active. PFC 80PLUS Platinum

Seasonic Prime Fanless PX-500 Platinum 500 W

Premium fanless power supply with platinum efficiency for completely silent computer operation

The Seasonic Prime Fanless PX-500 power supply represents the pinnacle in the field of silent computer power supply. Thanks to advanced fanless technology, it eliminates fan noise completely and ensures absolutely silent operation. With 80PLUS Platinum certification, it achieves high efficiency while maintaining stable power output 500 W.

The power supply uses passive cooling based on heat dissipation without moving parts, which not only reduces noise, but also energy consumption and extends the service life. Fully modular cables allow for optimal cable arrangement in the computer case and better airflow.
