300W ATX Power Supply for Modern Standby PCs

The KHACHIMO DPSN-300DB D is a new 300W ATX power supply designed for systems that support Modern Standby. It delivers fast wake-from-sleep times and improved low-load efficiency for compatible motherboards. The unit targets builders who need a compact, efficient power source for mainstream desktop configurations.

80 PLUS Gold Efficiency Rating

This power supply carries 80 PLUS Gold certification, confirming high efficiency across typical load ranges. The rating means lower power draw from the wall, reduced waste heat and quieter operation compared to lower-rated units. It is the single specification that determines whether the unit meets your efficiency and thermal requirements.

Resonant LLC Topology with Zero RPM Fan Mode

Under sustained load the resonant LLC topology with DC-to-DC conversion maintains clean, consistent power delivery while reducing coil whine. At low and medium loads the Zero RPM fan mode stops the cooling fan entirely for near-silent operation. The design also enables more energy-efficient sleep states during prolonged idle periods.
