400W 80 PLUS Gold ATX power supply

This 400 watt ATX power supply carries 80 PLUS Gold certification for high efficiency and lower running costs. It targets builders assembling compact or low-power systems who value quiet operation and modern sleep-state support.

Resonant LLC topology with DC-to-DC conversion

The resonant LLC design paired with DC-to-DC conversion delivers clean, consistent power while reducing coil whine. A zero-RPM fan mode stops the fan entirely at low and medium loads, keeping the system near-silent during everyday tasks.

Modern Standby compatibility and Gold efficiency

Modern Standby support enables extremely fast wake-from-sleep times and better low-load efficiency. The Gold-rated design cuts power consumption, noise and heat, making it suitable for energy-conscious builds that spend long periods idle.
