400W ATX Power Supply for Modern Standby

This new KHACHIMO unit delivers 400W continuous power through an ATX form factor. It carries 80 PLUS Gold certification and uses a resonant LLC topology with DC-to-DC conversion for stable voltage regulation. Modern Standby compatibility enables extremely fast wake-from-sleep times and improved low-load efficiency.

Suited for efficient low-load systems

Builders who want near-silent operation at idle will benefit from the Zero RPM fan mode that stops the fan entirely under light loads. The topology reduces coil whine and supports deeper sleep states for quiet office or home PCs. Buyers who need higher continuous output for multi-GPU configurations or extreme overclocking should look at higher-wattage units.

The deciding specification is the 400W ATX rating

This figure defines the total continuous power available to the system. The 80 PLUS Gold certification confirms high typical efficiency, lowering consumption and heat. Modern Standby support ensures compatibility with fast wake requirements on supported platforms.

Questions about this item

What does the 400W rating mean for my build?

It delivers up to 400W of continuous power to the components inside the case, suitable for mainstream CPUs and mid-range graphics cards.

What does the 80 PLUS Gold badge tell me about the ATX connection?

The Gold certification means the unit meets high efficiency targets across typical loads, so less energy is lost as heat through the standard ATX connectors.

Will this unit fit a standard ATX case and mount correctly?

Yes, it follows the ATX form factor so it fits standard ATX mounting points and uses the usual screw pattern.
