  • ATX 400 W switching power supply for reliable system power delivery

New 400W ATX power supply

This new KHACHIMO ATX power supply delivers 400W of continuous power for desktop PCs. It carries 80 PLUS Gold certification for high efficiency and lower heat output. Resonant LLC topology with DC-to-DC conversion provides clean, stable voltage rails. Modern Standby compatibility enables extremely fast wake-from-sleep times.

Suits quiet, efficient mainstream builds

Builders who want near-silent operation at low loads will benefit from the Zero RPM fan mode that stops the fan entirely. The Gold-rated efficiency and resonant topology reduce coil whine and power draw for cooler, quieter systems. It is not for high-end workstations or gaming rigs requiring more than 400W. Buyers needing higher wattage or redundant power modules must look elsewhere.

400W rated output decides fit

The single specification that determines compatibility is the 400W maximum output. Your components' combined peak power draw must stay within this limit for stable operation. Check GPU and CPU power requirements against this 400W ceiling before purchasing. No other specification overrides this hard capacity constraint.

Preguntas sobre este artículo

What is the maximum continuous power the 400W unit can deliver under sustained load?

The power supply is rated for 400W continuous output under sustained use.

How does the 80 PLUS Gold certification affect noise and heat during all-day operation?

Gold-rated efficiency reduces waste heat, so the fan runs slower or stays off at low and medium loads, keeping noise and temperatures lower.

Which motherboard power connectors must my board already have for this ATX supply to work?

Your motherboard needs a standard 24-pin ATX connector and a 4-pin or 8-pin CPU power connector to operate with this unit.
