Modern Standby ATX Supply

This 40 W ATX power supply delivers 12 V at 3.5 A and is built for systems that use Modern Standby sleep states. The 80 PLUS Gold rating means high efficiency at typical loads. Resonant LLC topology with DC-to-DC conversion provides clean power and reduces coil whine. A zero-RPM fan mode keeps the unit silent at low and medium loads.

Compatibility check

Verify that your chassis accepts a standard ATX form-factor unit and that the 12 V rail can satisfy every component in the build. Confirm the mainboard and firmware support Modern Standby for the advertised wake behaviour. Ensure the total system draw stays within the 40 W rating before ordering.

Build integration

The compact output frees headroom for low-power CPUs and integrated graphics without needing auxiliary PCIe connectors. Silent fan operation suits living-room or office builds where noise matters. High efficiency at light loads reduces heat, helping smaller cases stay cool. The DC-to-DC design supports deeper sleep states for lower standby power draw.
