ATX power supply for modern sleep states

This ATX unit targets builders who need a power source that supports Modern Standby for rapid wake times and improved low-load efficiency. The 80 PLUS Gold certification indicates high energy conversion that reduces waste heat and lowers overall consumption. It suits desktop systems where quiet operation and efficient idle behaviour are priorities.

Quiet operation with zero RPM mode

Resonant LLC topology paired with DC-to-DC conversion delivers clean, consistent output while minimising coil whine. The Zero RPM fan mode stops the cooling fan entirely at low and medium loads, enabling near-silent running during typical desktop tasks. This combination supports more energy efficient sleep states without audible distraction.

Limits of the 15.7 V 4 A design

The fixed 15.7 V output rated at 4 A restricts this unit to platforms designed for that specific voltage and current envelope. It cannot serve builds that require standard multi-rail ATX voltages or higher total wattage for discrete graphics cards. Buyers needing broader voltage rails or greater power headroom must select a different supply.

Perguntas sobre este artigo

What does the 80 PLUS Gold certification mean for real-world efficiency?

The 80 PLUS Gold rating guarantees high efficiency during operation, which reduces power consumption, lowers heat output, and results in quieter performance.

What form factor does this ATX power supply use for mounting?

This unit follows the standard ATX form factor, so it fits any chassis designed for ATX power supplies using the usual four mounting screws.

How do I enable the Zero RPM fan mode for silent operation?

The Zero RPM mode activates automatically at low and medium loads; no manual setup is required, but ensure your case airflow is sufficient for passive cooling.
