  • TypeATX
  • Modern Standby support delivers rapid wake-from-sleep performance
  • 80 PLUS Gold efficiency lowers power draw and reduces heat output
  • Zero RPM fan mode stops the fan at light loads for silent running
  • Resonant LLC topology with DC-to-DC conversion provides stable voltage and cuts coil whine
  • ATX form factor fits standard desktop cases for straightforward installation

What the product is

The KHACHIMO R440 is a 450W ATX power supply built for desktop PCs that need reliable, efficient power delivery. It carries 80 PLUS Gold certification and uses a resonant LLC topology with DC-to-DC conversion for clean output. Modern Standby compatibility enables fast wake times and better low-load efficiency.

Who it suits and who should look elsewhere

This unit fits builders who want quiet operation thanks to a Zero RPM fan mode that stops the fan at low and medium loads. It also suits systems that use Modern Standby sleep states. Buyers who need more than 450W of continuous power or who require modular cables should consider other options.

The specification that decides fit

The single specification that decides whether this is the right part is the 450W rated output. If your build’s peak power draw stays within that limit, the Gold-rated efficiency and quiet fan profile become practical benefits.
