ATX power supply with Modern Standby

This ATX power supply supports Modern Standby for extremely fast wake-from-sleep times and improved low-load efficiency. It suits builders who need quick system resume and reduced idle power draw. The unit carries 80 PLUS Gold certification for high-efficiency operation across typical loads.

Zero RPM fan mode and resonant LLC topology

At low and medium loads the cooling fan stops completely, enabling near-silent operation during everyday tasks. Resonant LLC topology with DC-to-DC conversion delivers clean, consistent power while reducing coil whine. These features combine to lower noise and support energy-efficient sleep states.

Gold efficiency for lower heat and power use

80 PLUS Gold certification means less wasted energy, cooler internal temperatures and quieter overall performance. The design targets builders who prioritise efficiency and acoustic comfort in daily use. It does not address buyers who require higher wattage or modular cable configurations not listed here.

Questions about this item

How do I install this ATX power supply in a standard case, and which step do people often skip?

Mount the unit with its four screws, connect the 24-pin motherboard and CPU power cables, then enable Modern Standby in the BIOS so the fast wake-from-sleep feature actually works.

What maintenance will this unit need after extended use?

The Zero RPM fan mode keeps the fan off at low loads, reducing dust buildup; clean the intake grill with compressed air once a year to maintain airflow.

Which limit appears first when the supply runs at high load for long periods?

The 80 PLUS Gold efficiency rating means heat rises with sustained load; the thermal protection circuit will throttle output before any component reaches its limit.
