400W ATX Power Supply

The KHACHIMO 400W ATX unit delivers 80 PLUS Gold certified efficiency for desktop builds that prioritise low power draw and quiet operation. Modern Standby compatibility ensures extremely fast wake-from-sleep times and better low-load efficiency. Resonant LLC topology with DC-to-DC conversion provides clean, consistent power and reduces coil whine.

Upgrade from Lower Efficiency Units

Replacing a standard Bronze or unrated power supply cuts waste heat and lowers electricity use, especially at idle where Modern Standby shines. The Zero RPM fan mode eliminates noise entirely at low and medium loads, a noticeable jump from units that spin constantly. The 60°C operating rating supports stable output in warmer chassis environments.

Fits Standard ATX Builds

The ATX form factor slots into typical desktop cases without adapter brackets. DC-to-DC conversion frees up minor rails for modern CPU and GPU loads while enabling deeper sleep states. Builders needing higher wattage for multi-GPU arrays or extreme overclocking should look beyond this 400W capacity.

Questions about this item

Will the ATX form factor fit my standard tower case?

The unit follows the ATX form factor, so it mounts in any standard tower case designed for ATX power supplies.

How do I connect the 24-pin ATX and CPU power cables during installation?

Seat the 24-pin motherboard connector first, then attach the 4+4-pin CPU cable; the step often missed is fully latching both clips until they click.

When should I clean or replace the cooling fan on this 400W unit?

With Zero RPM Fan Mode the fan stops at low load, so dust builds slowly; blow it out yearly and replace only if bearing noise appears.
