KHACHIMO

KHACHIMO 860W ATX Power Supply DG1W-3860V DG1W2-5860V3V

SKU CH-ZS5N-64RER

An 860 W ATX power supply with 80 PLUS Gold efficiency, zero-RPM fan mode and Modern Standby support for quiet, low-power sleep states

  • Product typeATX
  • Modern Standby gives extremely fast wake-from-sleep times and better low-load efficiency
  • 80 PLUS Gold certification means high efficiency for lower power consumption, less noise and cooler temperatures
  • Zero RPM fan mode stops the cooling fan at low and medium loads for near-silent operation
  • Resonant LLC topology with DC-to-DC conversion provides clean, consistent power and reduces coil whine
  • ATX form factor 860W switching power supply fits standard desktop builds

860W ATX Power Supply

This KHACHIMO unit delivers 860 watts of continuous power in a standard ATX form factor. It carries 80 PLUS Gold certification for high efficiency across typical loads. Modern Standby compatibility enables rapid wake-from-sleep transitions and improved low-load efficiency. The resonant LLC topology with DC-to-DC conversion provides clean, stable voltage regulation for modern components.

Builders seeking quiet operation

The Zero RPM fan mode stops the fan completely at low and medium loads for near-silent running. Resonant LLC topology with DC-to-DC conversion reduces coil whine for quieter operation overall. Systems that do not require Modern Standby fast wake times or 80 PLUS Gold efficiency levels may not need this feature set. Buyers needing higher wattage output should consider a larger capacity unit.

Sustained load behaviour and thermal management

Under sustained load the power supply maintains high efficiency thanks to its 80 PLUS Gold rating, resulting in lower power draw and reduced heat output. The resonant LLC topology with DC-to-DC conversion delivers consistent power without voltage drift during extended use. The cooling fan engages automatically when load increases beyond the Zero RPM threshold. This design supports energy efficient sleep states during idle periods.

Questions about this item

What motherboard power connector does this ATX supply need to fit my build?

It uses the standard ATX 24-pin main connector plus the usual 4+4-pin CPU and PCIe cables that come with the unit.

Will my older GPU that still draws power through a 6-pin plug work with this 860W unit?

Yes, the included PCIe cables provide 6+2-pin connectors that are backward compatible with 6-pin graphics cards.

How can I confirm the Zero RPM mode is actually active after I install the supply?

Under light load the fan will stay completely still; you can verify by watching the fan through the grille while the system idles.
