595W ATX Power Supply for Modern Standby Systems

This 595W ATX power supply delivers 80 PLUS Gold certified efficiency for lower power consumption and cooler operation. It is built for PCs that use Modern Standby, providing extremely fast wake-from-sleep times and improved low-load efficiency. The resonant LLC topology with DC-to-DC conversion ensures clean, consistent power delivery. It suits builders wanting a quiet, efficient unit for compatible desktops.

Standard ATX Installation with Zero RPM Fan Mode

The unit fits standard ATX mounting points and uses conventional connectors for straightforward installation. A Zero RPM fan mode stops the cooling fan entirely at low and medium loads for near-silent operation. The resonant LLC topology also reduces coil whine for quieter performance overall. Ensure cables are routed cleanly to avoid obstructing the fan intake when it does spin.

Verify ATX Compatibility and Modern Standby Support

Before ordering, confirm your case accepts a standard ATX power supply and that your motherboard supports Modern Standby to use the fast wake features. Check that the provided connectors match your components, including CPU and GPU power requirements. The 595W capacity should cover the total system power draw under load. This unit is not for builds needing higher wattage or non-ATX form factors.
