400W ATX power supply for efficient builds

The KHACHIMO 7000 9000 delivers 400W of continuous power in a standard ATX form factor. It carries 80 PLUS Gold certification for high efficiency across typical loads. Modern Standby compatibility enables extremely fast wake-from-sleep times and better low-load efficiency. The unit suits mainstream desktops and office systems that prioritise quiet, efficient operation.

Check motherboard power connectors

Verify that your motherboard uses the standard 24-pin ATX and 4-pin or 8-pin CPU power connectors this unit provides. Confirm the chassis has an ATX power supply bay with sufficient depth for a typical unit. Ensure the total system power draw stays within the 400W rating, including graphics card and drive requirements. No adapter cables are mentioned in the specifications.

Resonant LLC topology with DC-to-DC conversion

The resonant LLC topology combined with DC-to-DC conversion supplies clean, consistent power and reduces coil whine for quieter operation. Zero RPM fan mode stops the cooling fan entirely at low and medium loads for near-silent running. These features also support more energy-efficient sleep states during daily use. The Gold-rated efficiency helps lower power consumption and operating temperatures.
