  • Modern Standby for ultra-fast wake times and efficient low-power states
  • 80 PLUS Gold efficiency reduces consumption, heat and fan noise
  • Zero RPM fan mode stops the fan completely at light loads for silent running
  • Resonant LLC topology with DC-to-DC delivers clean power and cuts coil whine
  • ATX form factor fits standard desktop cases for easy integration

Modern Standby ATX Power Supply

This KHACHIMO ATX power supply is built for desktop systems that require fast wake-from-sleep response and high efficiency. It carries 80 PLUS Gold certification and uses Resonant LLC topology with DC-to-DC conversion for clean power delivery. Zero RPM fan mode stops the fan at low and medium loads for near-silent operation.

Quiet High-Efficiency Builders vs Legacy Sleep

The unit suits builders who want lower power consumption, reduced noise and cooler temperatures alongside Modern Standby support. It is not for systems that cannot use Modern Standby sleep states or for buyers who need a power supply without semi-passive fan behaviour.

80 PLUS Gold Efficiency Rating

The single specification that decides fit is the 80 PLUS Gold certification, which confirms high efficiency operation across typical loads. This rating directly determines the lower power draw, reduced heat output and quieter performance the design targets.

Questions about this item

What does the 80 PLUS Gold certification mean for daily power draw?

It guarantees high efficiency across typical loads, lowering electricity use, heat output and fan noise compared with lower-rated units.

How does Modern Standby compatibility change wake times?

The power supply supports the Modern Standby sleep state, allowing the system to resume from sleep in seconds rather than the longer delay of traditional S3 sleep.

When does the Zero RPM fan mode actually stop the fan?

The fan stays off at low and medium loads, spinning up only when the unit reaches higher power demand or temperature thresholds.
