300 W ATX power supply

The KHACHIMO SP302-1S delivers 300 W of continuous power in a standard ATX form factor. It is built for compact desktop builds and replacement scenarios where a reliable, efficient unit is required. The 80 PLUS Gold certification confirms high efficiency across typical loads, reducing waste heat and electricity draw.

1U form factor and modern standby support

The 1U height allows installation in slim chassis and rackmount enclosures where vertical space is limited. Modern Standby compatibility enables extremely fast wake-from-sleep times and improved low-load efficiency. Resonant LLC topology with DC-to-DC conversion provides clean, consistent power while reducing coil whine and supporting deeper sleep states.

Zero RPM fan mode and efficiency headroom

At low and medium loads the cooling fan stops completely for near-silent operation. The Gold-rated design keeps temperatures lower than lower-tier units under the same demand. Builds requiring more than 300 W or multiple high-power graphics cards will exceed this unit's capacity.

Perguntas sobre este artigo

Does the 300W rating hold under continuous full-load operation?

The unit is rated to deliver 300 W continuously; 80 PLUS Gold certification means it meets that output while maintaining high efficiency.

How loud does the fan get during an all-day workload?

Zero RPM mode keeps the fan off at low and medium loads, and the resonant LLC topology with DC-to-DC conversion reduces coil whine for quieter operation.

Will this 1U supply fit a standard ATX case I already own?

The power supply uses the ATX form factor, so it fits cases designed for standard ATX units.
