A 15 V, 50 W ATX power supply with 80 PLUS Gold efficiency, Modern Standby support, zero-RPM fan mode and resonant LLC topology for quiet, stable power

  • TypeATX
  • Modern Standby support for faster wake-from-sleep and better low-load efficiency
  • 80 PLUS Gold certification for high efficiency, lower power draw and cooler running
  • Zero RPM fan mode stops the fan at low to medium loads for silent operation
  • Resonant LLC topology with DC-to-DC conversion delivers clean power and reduces coil whine
  • 15 V 50 W ATX power supply built for efficient, quiet performance

Compact 50W ATX unit

The KHACHIMO 15V 50W ATX power supply delivers 50 watts of continuous power on a single 15 volt rail for low-power builds and embedded systems. Its 80 PLUS Gold certification confirms high efficiency across typical load ranges. Modern Standby compatibility allows extremely fast wake-from-sleep transitions for responsive operation. The resonant LLC topology with DC-to-DC conversion provides clean, consistent power delivery.

Zero RPM fan and thermals

At low and medium loads the cooling fan stops completely, enabling near-silent operation in quiet environments. The 80 PLUS Gold efficiency rating reduces waste heat, helping to keep internal temperatures lower during normal use. Resonant LLC topology with DC-to-DC conversion minimises coil whine for quieter acoustic performance. Modern Standby support enables more energy-efficient sleep states when the system is idle.

Sustained load behaviour

Under sustained load the resonant LLC topology with DC-to-DC conversion maintains clean, consistent power output without voltage drift. The 80 PLUS Gold efficiency level continues to limit excess heat generation during extended operation. Zero RPM fan mode disengages automatically when thermal thresholds rise, activating active cooling as needed. Modern Standby readiness ensures efficient transitions back to full power after prolonged idle periods.

Questions about this item

How do I install this 15V 50W ATX power supply and what is the common mistake?

Mount the unit in the case, connect the 24-pin ATX and any required CPU or peripheral cables, then route the AC cord. The step often missed is enabling the Modern Standby wake settings in the motherboard BIOS so the fast sleep and wake behaviour actually works.

What maintenance will this 50W Gold-rated supply need later?

Dust the intake and exhaust areas every few months to keep airflow clear. The Zero RPM fan mode means the fan stops at low load, so dust buildup can go unnoticed until higher loads spin it up; regular cleaning prevents that.

What limit appears first when this 15V unit runs at sustained load?

The 50 W maximum output is the hard ceiling. Continuous draw at or near that level will hit the power limit before thermal or efficiency limits become the bottleneck.
