  • TypeATX
  • Modern Standby support for near-instant wake from sleep

Compact 400W ATX supply for space-constrained builds

The KHACHIMO FSP400-60WS1 is a 400W ATX power supply designed for compact 1U chassis and small-form-factor systems. It targets builders who need reliable power in tight enclosures where standard PSU dimensions will not fit. The unit delivers 400W of continuous output suitable for mainstream components.

Fits 1U layouts and enables modern sleep states

This supply requires a chassis with a 1U power supply bay and standard ATX motherboard connectors. Its Resonant LLC topology with DC-to-DC conversion provides clean power rails and supports deeper, more energy efficient sleep states. Modern Standby compatibility allows the system to wake extremely fast from low-power modes. The design frees up internal volume that larger supplies would occupy.

Gold efficiency and silent fan profile reduce heat

80 PLUS Gold certification means high efficiency across typical loads, lowering power draw and waste heat. Zero RPM fan mode stops the cooling fan entirely at low and medium loads for near-silent operation. The same topology that enables efficient sleep states also reduces coil whine. Together these features create a quieter, cooler running system without extra software or accessories.

Questions about this item

What sustained load triggers the fan to start spinning on this 400W unit?

The Zero RPM Fan Mode keeps the fan off at low and medium loads; it only spins up when the load exceeds the medium threshold.

How loud and hot does the FSP400-60WS1 get during all-day operation?

80 PLUS Gold efficiency reduces waste heat, and the Zero RPM mode keeps it near-silent at typical loads; the fan runs only under heavier sustained demand.

Which motherboard power connectors must my build already have for this ATX supply?

It uses the standard ATX 24-pin main connector plus the 4/8-pin CPU power connector found on modern motherboards.
