750W ATX Power Supply for Modern Standby Systems

This KHACHIMO unit delivers 750W of continuous power in a standard ATX form factor. It is built for desktops that use Modern Standby sleep states, offering extremely fast wake times and improved low-load efficiency. The 80 PLUS Gold certification confirms high energy efficiency across typical workloads. Builders seeking a reliable, quiet foundation for a contemporary PC will find it well suited.

Practical limits of ATX and Modern Standby

The ATX standard defines physical dimensions and connector layouts that must match the case and motherboard; this unit follows those dimensions. Modern Standby support requires the platform firmware and operating system to implement the low-power idle states that the supply enables. Zero RPM fan mode only engages at low and medium loads, so the fan will spin under heavier demand. Efficiency gains from the Gold rating are most visible at typical system loads rather than at the extremes.

Resonant LLC topology with DC-to-DC conversion

This topology provides clean, consistent power delivery while reducing coil whine for quieter operation. It also allows the supply to support more energy-efficient sleep states required by Modern Standby. Buyers who need a different total wattage or a non-ATX form factor should look elsewhere.

Questions about this item

How do I pick the right capacity for this 750 W unit?

The 750 W rating is the single capacity offered; choose it when your system’s peak draw stays comfortably below that figure.

What does the 80 PLUS Gold rating deliver in daily use?

It guarantees at least 80 % efficiency at typical loads, cutting waste heat and fan noise compared with lower-rated units.

What ATX standard does this supply follow and what does it cap?

The ATX form factor sets the physical dimensions and connector layout; it does not limit the 750 W output.
