KHACHIMO LCM300N 300W ATX 80 PLUS Gold power supply

SKU CH-ZXBG-JF446

A 300 W ATX power supply with 80 PLUS Gold efficiency, Modern Standby support, zero-RPM fan mode and resonant LLC topology for quiet, efficient operation

  • Product typeATX
  • Faster wake from sleep with Modern Standby support
  • Lower power draw and cooler running with 80 PLUS Gold certification
  • Near-silent operation at typical loads thanks to Zero RPM fan mode
  • Clean, stable power delivery via resonant LLC and DC-to-DC conversion
  • Reduced coil whine and quieter sleep states from advanced topology

Ideal for Modern Standby systems

This 300W ATX power supply targets builders who need fast wake-from-sleep response and high efficiency in a compact desktop or workstation. It suits configurations that prioritise low standby draw and quiet operation over high continuous load. Systems with power-hungry discrete graphics or multiple storage arrays are not the intended use case.

300W continuous output with 80 PLUS Gold efficiency

The unit delivers up to 300W of regulated power while maintaining Gold-level efficiency across typical loads, reducing waste heat and electricity cost. Headroom is sufficient for mainstream CPUs and integrated graphics, but sustained heavy GPU compute or multi-rail overclocking will exceed its capacity.

Resonant LLC topology and Zero RPM fan mode

DC-to-DC conversion and resonant LLC design provide clean voltage regulation and suppress coil whine for a quieter build. The fan stops completely at low and medium loads, enabling near-silent idle and light-work states. Standard ATX mounting and cabling simplify installation in compatible chassis.
