400W ATX Power Supply

This KHACHIMO unit delivers 400 watts through an ATX form factor for desktop builds. It carries 80 PLUS Gold certification for high efficiency, lower consumption, and cooler running. Modern Standby support enables extremely fast wake-from-sleep times and improved low-load efficiency. Resonant LLC topology with DC-to-DC conversion provides clean power and reduces coil whine.

For Quiet, Efficient Desktop Builds

The zero RPM fan mode stops the fan at low and medium loads for near-silent operation, suiting home or office PCs where noise matters. Gold efficiency helps keep electricity costs and heat down over long uptime. Systems requiring more than 400 watts or redundant power configurations should look at higher-capacity units.

Modern Standby and Topology Benefits

Modern Standby compatibility changes how the PC enters and leaves sleep, giving faster resume and better efficiency at idle. The resonant LLC design with DC-to-DC conversion changes voltage regulation quality, cutting ripple and coil noise while supporting deeper sleep states. No separate software bundle or extra cables are mentioned in the specifications.

Questions about this item

What type of motherboard power connector does the ATX 400W unit require?

It uses the standard 24-pin ATX main connector and a 4-pin or 8-pin CPU power connector found on compatible motherboards.

Will the Zero RPM fan mode still operate if I keep an older mechanical hard drive in the system?

Yes, the fan remains off at low and medium loads regardless of the storage devices installed.

How can I confirm the 80 PLUS Gold efficiency is active after installation?

Check that the system enters Modern Standby sleep and wakes instantly; the fan should stay off at idle and the unit runs cool.
