400W ATX power supply

The KHACHIMO PCD023 is a 400W ATX power supply built with 80 PLUS Gold certification for high efficiency. It targets system builders who need reliable power delivery for mainstream desktop configurations. Modern Standby support allows extremely fast wake-from-sleep times and improved low-load efficiency.

Zero RPM fan mode and LLC topology

At low and medium loads the cooling fan stops completely for near-silent operation. Resonant LLC topology with DC-to-DC conversion supplies clean, consistent power while reducing coil whine. These features together enable quieter performance and more energy-efficient sleep states.

Check your component power draw

Verify that the total system power requirement stays within the 400W rating, including CPU and graphics card demands. Ensure your motherboard and graphics card connectors match the unit's cable set. Buyers whose builds exceed this wattage or need additional PCIe connectors should consider a higher-capacity unit.

Questions about this item

Will the fan need replacement after years of continuous operation?

The Zero RPM fan mode keeps the fan off at low and medium loads, reducing wear and extending its service life.

What limits sustained output before protection engages?

The 400 W rated capacity is the ceiling; exceeding it triggers over-power protection.

How loud and hot does the unit get when running all day?

Zero RPM mode keeps it silent at typical loads, while 80 PLUS Gold efficiency minimises waste heat.
