ATX 400W Power Supply for Modern Standby Systems

The KHACHIMO H41014 is a new ATX power supply rated at 400W, designed for systems that support Modern Standby. It delivers 80 PLUS Gold certified efficiency, reducing power draw and heat output. Resonant LLC topology with DC-to-DC conversion provides stable voltage regulation and enables low-power sleep states. A Zero RPM fan mode keeps the unit silent under light and medium workloads.

Ideal for Efficient, Quiet Builds.

This unit suits builders who prioritise low noise and high efficiency in standard desktop or workstation chassis. The fan-stop feature and Gold-rated design benefit environments where acoustic performance matters. Systems with power-hungry multi-GPU setups or heavily overclocked CPUs will exceed the 400W capacity and should look at higher-wattage alternatives.

400W Continuous Output Rating

The 400W maximum power rating is the single specification that determines compatibility with your component list. Add the peak power draw of your CPU, GPU, drives and peripherals; if the total approaches or surpasses 400W, this supply cannot safely support the build. No other figure in the data overrides this limit.

Questions sur cet article

How much noise and heat should I expect from the 400 W unit during all-day use?

The 80 PLUS Gold rating means high efficiency, so less waste heat and lower fan speeds. Zero RPM mode stops the fan completely at low and medium loads, giving near-silent operation, while the resonant LLC topology reduces coil whine.

What must my system already have for this ATX power supply to work?

Your case needs a standard ATX PSU mounting area and your motherboard requires a 24-pin ATX connector plus the appropriate CPU and PCIe power cables for your components.

Will the Modern Standby support work with an older motherboard that lacks Modern Standby?

Yes, the PSU remains fully functional as a standard ATX supply; Modern Standby features simply remain inactive on boards that do not implement the sleep state.
