KHACHIMO PVSE 400/24-20 ATX power supply

ATX Power Supply with Gold Efficiency

The KHACHIMO PVSE 400/24-20 is an ATX power supply rated at 400 W with an 80 PLUS Gold certification. It delivers a 24 V output at 20 A and uses resonant LLC topology with DC-to-DC conversion for clean, consistent power. Modern Standby compatibility enables extremely fast wake-from-sleep times and better low-load efficiency. A zero RPM fan mode stops the cooling fan entirely at low and medium loads for near-silent operation.

Suitable for Efficient, Quiet Builds

This unit suits builders who want high efficiency, low noise and Modern Standby support in a standard ATX form factor. The Gold-rated design reduces power consumption and heat output while the zero RPM fan mode keeps acoustics minimal during light workloads. Buyers who need higher wattage for multi-GPU configurations or extreme overclocking headroom should consider other options, as this model targets mainstream efficiency and quiet operation.

400 Watt Output with 24 Volt Rail

The single specification that decides fit is the 400 W total capacity combined with a 24 V rail rated at 20 A. This defines the maximum power available for components and the current limit on the primary voltage rail, determining whether the unit can support a given system's peak demand.
