SKU CH-RGBE-8CY8N

An ATX power supply with 80 PLUS Gold efficiency, zero-RPM fan mode and Modern Standby compatibility for silent, low-power sleep states

  • TypeATX
  • Fast wake-from-sleep with Modern Standby support
  • Lower power draw and cooler temps via 80 PLUS Gold efficiency
  • Near-silent operation at low loads with Zero RPM fan mode
  • Clean, stable power delivery through resonant LLC and DC-to-DC topology
  • Reduced coil whine for quieter system performance

KHACHIMO ATX Gold Power Supply

The KHACHIMO CA05951-8730 is an ATX power supply built for modern desktop systems. It carries 80 PLUS Gold certification, delivering high efficiency that reduces power draw, heat and fan noise. Modern Standby compatibility ensures extremely fast wake-from-sleep times and improved low-load efficiency. This unit suits builders who want reliable, efficient power for everyday computing and gaming rigs.

Build integration and silent operation

A Zero RPM fan mode stops the cooling fan completely at low and medium loads, providing near-silent operation during light tasks. The resonant LLC topology with DC-to-DC conversion supplies clean, consistent power while reducing coil whine. This design also enables more energy-efficient sleep states, helping the system stay quiet and cool. Standard ATX dimensions mean it fits typical chassis layouts without special mounting requirements.

Upgrading from older or basic units

Replacing an older, lower-efficiency supply with this Gold-rated model cuts wasted electricity and lowers system temperatures. The tighter voltage regulation from DC-to-DC conversion improves stability for sensitive components. Builders moving from units without Modern Standby support gain instant wake capability. It is not for systems that demand server-grade redundancy or specialised form factors beyond standard ATX.

Questions sur cet article

What sustained-load limit appears first with the 80 PLUS Gold efficiency rating?

The 80 PLUS Gold certification means the unit maintains high efficiency up to its rated capacity, reducing waste heat before thermal limits become the bottleneck.

How does the Zero RPM fan mode affect noise and heat during all-day operation?

At low and medium loads the fan stays completely off, giving near-silent running and lower temperatures thanks to the resonant LLC topology with DC-to-DC conversion.

Which motherboard feature must already be present for Modern Standby to work with this PSU?

Your motherboard needs to support Modern Standby sleep states so the power supply can enable extremely fast wake times and improved low-load efficiency.
