  • 80 PLUS Gold certification cuts electricity use and heat
  • Zero RPM mode stops the fan at low and medium loads for silent running
  • Resonant LLC topology with DC-to-DC conversion delivers clean power and reduces coil whine
  • Modern Standby support enables extremely fast wake-from-sleep and better low-load efficiency
  • ATX form factor fits standard desktop cases

ATX Power Supply for Modern Standby Builds

This ATX power supply targets builders who want fast wake-from-sleep performance and lower electricity draw at idle. The 80 PLUS Gold certification confirms high efficiency across typical loads. It suits systems that spend long periods in low-power states. Buyers needing a non-ATX form factor or higher certified efficiency should look elsewhere.

Fits Standard ATX Cases with DC-to-DC Topology

The unit uses resonant LLC topology with DC-to-DC conversion to deliver stable voltage to modern components. This design supports energy-efficient sleep states required by Modern Standby hardware. It requires an ATX-compatible chassis and standard motherboard power connectors. Builders using proprietary or small-form-factor cases cannot use this supply.

Zero RPM Fan Mode Cuts Noise at Low Load

At low and medium loads the cooling fan stops completely, removing audible noise during desktop work or media playback. Gold-rated efficiency reduces waste heat, helping keep internal temperatures down. The topology also minimises coil whine for quieter operation overall. Users running sustained heavy loads will hear the fan spin up.

Questions about this item

Does the 80 PLUS Gold certification keep this unit cool and quiet under sustained load?

Yes, the 80 PLUS Gold rating means high efficiency, which lowers power consumption, reduces heat output and cuts fan noise during long sessions.

Will the fan stay off once the system has been running all day at typical loads?

The Zero RPM Fan Mode stops the fan completely at low and medium loads, so it can remain silent even after hours of operation.

What motherboard power connector does this ATX supply need to work?

It requires a standard 24-pin ATX motherboard connector, which is present on any compatible ATX motherboard.
