ATX power supply delivering 350 W with 80 PLUS Gold efficiency, zero-RPM fan mode for silent low-load operation, and Modern Standby compatibility for instant wake

  • TypeATX
  • Modern Standby support gives extremely fast wake-from-sleep times
  • 80 PLUS Gold certification lowers power draw and keeps temperatures down
  • Zero RPM fan 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
  • 350 W ATX power supply fits standard desktop builds

Capacity and Use Case

The KHACHIMO ST-350BKV is a 350W ATX power supply built for new systems that need reliable, efficient power delivery. It suits office PCs, home-theatre builds and other low-draw configurations where quiet operation matters more than maximum wattage. Builders planning multi-GPU rigs or high-end workstations should look elsewhere because this unit cannot meet those power demands.

Efficiency and Noise Behaviour

80 PLUS Gold certification means the supply runs with high efficiency, reducing consumption, heat and overall noise. Modern Standby compatibility enables extremely fast wake-from-sleep times and better low-load efficiency. The Zero RPM Fan Mode stops the cooling fan entirely at low and medium loads for near-silent operation. Resonant LLC topology with DC-to-DC conversion provides clean, consistent power, reduces coil whine and supports more energy-efficient sleep states.

Installation Notes

Standard ATX dimensions and cabling allow straightforward mounting in compatible cases. The fan-stop feature activates automatically, so no software setup is required to benefit from silent running. Ensure the case provides adequate airflow around the unit; restricted ventilation can prevent the fan from remaining off when loads are light. Verify that the available connectors match your motherboard and peripherals before beginning the build.

Domande su questo articolo

Will the fan ever need replacement if it stops completely under light load?

The Zero RPM Fan Mode keeps the fan off at low and medium loads, reducing wear so the fan should last longer than in units that run constantly.

What limits continuous output before protection triggers?

The 350 W rated capacity is the sustained limit; drawing more will activate over-power protection and shut the unit down.

How loud and hot does it get when running all day at typical loads?

80 PLUS Gold efficiency and Zero RPM Fan Mode keep noise near zero and temperatures low during everyday use.
