SKU CH-VE7Y-6YG6J

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

  • TypeATX
  • Modern Standby support for extremely fast wake-from-sleep and better low-load efficiency
  • 80 PLUS Gold certified for high efficiency, lower power use, less noise and cooler temps
  • Zero RPM fan mode stops the fan at low and medium loads for near-silent operation
  • Resonant LLC topology with DC-to-DC conversion delivers clean, consistent power and reduces coil whine
  • DC-to-DC conversion enables more energy-efficient sleep states for improved system efficiency

ATX power supply for modern sleep states

This KHACHIMO unit fits standard ATX bays and is built for systems that rely on Modern Standby for instant wake and efficient low-power sleep. The 80 PLUS Gold certification means it runs efficiently across typical loads, reducing waste heat and fan noise. It suits builders who want quiet, reliable power without configuring custom curves.

Capacity and headroom

The 5300 model designation indicates the rated output this design targets, giving headroom for mainstream CPUs and single mid-range graphics cards under sustained load. Peak demands from heavy overclocks or multi-GPU arrays will exceed its capability, so the fan will spin up earlier and efficiency drops at the top end. It covers everyday gaming and productivity workloads comfortably.

80 PLUS Gold efficiency

Gold-rated efficiency is the single figure that decides whether this unit matches a build focused on low electricity draw and quiet operation at idle. If the project demands a higher certification tier or a lower price point, this supply does not fit.
