  • TypeATX
  • Modern Standby support gives near-instant wake from sleep
  • 80 PLUS Gold certification cuts power draw and heat
  • Zero RPM fan mode stops the fan at light loads
  • Resonant LLC with DC-to-DC topology delivers clean, stable power
  • ATX form factor fits standard desktop cases

Modern Standby & 80 PLUS Gold

The KHACHIMO ML110G9 is a 550W ATX power supply built for systems that demand fast wake-from-sleep and high efficiency. It suits builders who want certified gold-class power without paying for unused headroom. Buyers needing significantly more wattage for multi-GPU rigs should look elsewhere.

Sustained-load behaviour

Resonant LLC topology with DC-to-DC conversion delivers clean, consistent output during extended sessions. The design maintains stable voltages and reduces coil whine while supporting modern energy-efficient sleep states. It is not intended for continuous loads far beyond its rated capacity.

Thermals, noise & power draw

Zero RPM fan mode stops the cooling fan completely at low and medium loads for near-silent running. 80 PLUS Gold certification ensures lower power consumption, less waste heat and cooler internal temperatures under normal use. Efficiency stays high across typical workloads.

Questions about this item

How does the Zero RPM Fan Mode and 80 PLUS Gold rating affect noise and heat when the 550 W supply runs all day?

At low and medium loads the cooling fan switches off entirely for near-silent operation, while Gold efficiency lowers power consumption and keeps temperatures cooler.

Which cables or connectors must already be present in the build for this ATX 550 W unit to work?

A standard ATX 24-pin motherboard connector and EPS 8-pin CPU power lead are required; the unit uses regular ATX pin-outs so existing modular cables from the same platform will fit.

Will the Resonant LLC topology and Modern Standby support cause issues with older components I keep?

The topology provides clean, consistent power and reduces coil whine, while Modern Standby enables faster wake times and efficient sleep states compatible with legacy hardware.
