400 W ATX Power Supply for Modern Standby Systems

This 400 W ATX unit delivers 80 PLUS Gold certified efficiency and is built for Modern Standby compatibility. Resonant LLC topology with DC-to-DC conversion provides clean power and reduces coil whine. It suits builders who want fast wake-from-sleep and quiet low-load operation.

Check ATX Form Factor and Connector Requirements

Verify that your chassis accepts a standard ATX power supply and that your motherboard uses the main and CPU power connectors this unit provides. Confirm the total system power draw stays within the 400 W rating before ordering. Buyers needing higher wattage for multi-GPU setups or extreme overclocking should look elsewhere.

Zero RPM Fan Mode Enables Near-Silent Idle

At low and medium loads the cooling fan stops completely, removing audible noise during desktop use or media playback. The Modern Standby support allows extremely fast wake times and more efficient sleep states. No extra software or cables are bundled to change this behaviour.
