ATX power supply for modern sleep states

The KHACHIMO SNP-B309 is an ATX power supply designed for systems that rely on Modern Standby. It supports 80 PLUS Gold efficiency, reducing power draw and heat output during everyday workloads.

Zero RPM fan mode for quiet low-load operation

At low and medium loads the cooling fan stops completely, removing audible noise while the system idles or handles light tasks. Resonant LLC topology with DC-to-DC conversion delivers stable voltage and enables deeper sleep states.

Gold certification and topology reduce coil whine

The 80 PLUS Gold rating confirms high efficiency across the load range. Combined with the resonant LLC design, it minimises coil whine and keeps temperatures lower without extra configuration.
