SKU CH-E3YT-XT0HS

ATX power supply delivering 400 W at 110 V DC with 80 PLUS Gold efficiency, zero-RPM fan mode and resonant LLC topology for quiet, efficient operation

  • TypeATX
  • Modern Standby compatible for extremely fast wake-from-sleep and better low-load efficiency
  • 80 PLUS Gold certified for high efficiency, lower power consumption, less noise and cooler temperatures
  • Zero RPM fan mode stops the fan at low and medium loads for near-silent operation
  • Resonant LLC topology with DC-to-DC conversion delivers clean, consistent power and reduces coil whine
  • ATX form factor DC110V 400W switching power supply model EHG2-6400F

400 W ATX power supply

The KHACHIMO EHG2-6400F is a 400 W ATX power supply designed for modern desktop builds that demand efficient, low-noise operation. It suits system integrators and enthusiasts who want gold-rated efficiency without excess wattage headroom.

Sustained load behaviour

Resonant LLC topology with DC-to-DC conversion delivers stable voltage regulation across continuous workloads, keeping ripple low and protecting components during extended sessions. The design supports Modern Standby sleep states for rapid wake times and efficient idle power draw.

Thermals noise and power draw

80 PLUS Gold certification confirms high efficiency at typical loads, reducing waste heat and overall power consumption. Zero RPM fan mode stops the cooling fan entirely at low and medium loads for near-silent operation, while the topology minimises coil whine.

Questions sur cet article

How does the 80 PLUS Gold rating and Zero RPM fan mode affect noise and heat during all-day use?

The 80 PLUS Gold certification ensures high efficiency for lower power draw and cooler temperatures, while the Zero RPM mode stops the fan completely at low and medium loads for near-silent operation.

What motherboard and CPU power connectors are required for this ATX unit to work?

This ATX power supply provides a 24-pin main motherboard connector and an 8-pin EPS connector for the CPU, which are the essential interfaces for powering a standard desktop system.

Will the Modern Standby compatibility and LLC topology work properly with older components I keep?

Modern Standby compatibility enables faster wake times and efficient sleep states with supported hardware, while the resonant LLC topology with DC-to-DC conversion delivers clean, stable power suitable for both newer and legacy components.
