400W ATX Gold Power Supply

The KHACHIMO FSP unit delivers 400W of continuous power through an ATX form factor. It carries 80 PLUS Gold certification for high efficiency at typical loads. Modern Standby compatibility enables extremely fast wake-from-sleep times and improved low-load efficiency. Resonant LLC topology with DC-to-DC conversion provides clean, consistent power and reduces coil whine.

Standard ATX Installation

The supply fits standard ATX mounting points and uses conventional mains and DC connectors. Zero RPM fan mode keeps the unit silent at low and medium loads by stopping the fan entirely. Resonant LLC topology with DC-to-DC conversion minimises coil whine for quieter operation. Ensure all motherboard and peripheral cables are fully seated to avoid intermittent power delivery.

Verify 400W Meets System Demand

Confirm the total system power draw stays within the 400W rating before ordering. Check that your case accepts a standard ATX power supply and that required connectors match your motherboard and graphics card. Modern Standby support requires a compatible motherboard and operating system to function. Builders needing higher wattage or additional PCIe connectors should consider a larger unit.

Perguntas sobre este artigo

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

The unit runs cooler and draws less power at the wall, and the fan stays off at low and medium loads thanks to the Zero RPM mode.

What comes in the box and what must I source separately?

The box contains the 400 W ATX power supply with its fixed cable harness; you only need to provide the IEC mains lead and mounting screws.

Which version should I choose between the FSP400-60PFN and FSP400-60PLN models?

Both are 400 W ATX units with 80 PLUS Gold, Modern Standby support, Zero RPM fan mode and LLC resonant topology with DC-to-DC conversion.
