Modern Standby ATX Power Supply

This 550W ATX unit carries 80 PLUS Gold certification and supports Modern Standby for rapid wake-from-sleep and improved low-load efficiency. Resonant LLC topology with DC-to-DC conversion delivers clean, consistent power while reducing coil whine. A Zero RPM fan mode stops the fan completely at low and medium loads for near-silent operation.

Compatibility Check Before Ordering

Verify your case accepts a standard ATX power supply and that the motherboard uses a 24-pin ATX and compatible CPU power connector. Ensure the total system power draw stays within the 550W rating by adding CPU, GPU and peripheral requirements. Confirm the unit’s physical length clears drive cages and cable routing channels inside your chassis.

Build Integration

The supply replaces any standard ATX unit and provides the rails needed for modern CPUs and graphics cards. High efficiency at typical loads lowers heat output, easing case airflow demands. Zero RPM fan mode eliminates fan noise during office work or media playback, while Modern Standby support enables faster sleep transitions without extra configuration.
