KHACHIMO 4.5V 40A 300W ATX power supply

SKU CH-HTKM-3J6J2

An ATX power supply delivering 4.5V at 40A for 300W with 80 PLUS Gold efficiency, Modern Standby support, zero-RPM fan mode and resonant LLC topology with DC-to-DC conversion

  • TypeATX
  • Extremely fast wake-from-sleep with Modern Standby compatibility
  • High efficiency operation backed by 80 PLUS Gold certification
  • Near-silent operation at low loads through Zero RPM fan mode
  • Clean, consistent power delivery via resonant LLC topology with DC-to-DC conversion
  • 300 W ATX power supply delivering 40 A on the 4.5 V rail

Purpose and audience

This 300 W ATX unit delivers 4.5 V at 40 A for systems built around the MCP300WL-4.5 platform. It targets builders who need a compact, efficient power source for low-voltage industrial or embedded boards.

Efficiency and standby behaviour

80 PLUS Gold certification confirms high efficiency across typical loads, reducing waste heat and acoustic output. Modern Standby support allows rapid wake-from-sleep transitions while maintaining low idle draw.

Installation notes

Standard ATX dimensions and connector layout simplify integration into compatible chassis. The Zero RPM fan mode activates automatically at low and medium loads, eliminating the need for manual fan curves. Ensure the 4.5 V rail matches the board specification before powering on.

この商品に関する質問

Should I pick the 4.5 V 40 A version or a different capacity for my MCP300WL-4.5?

The 4.5 V 40 A model is the exact match for the MCP300WL-4.5, delivering 300 W at the required voltage and current.

What does the 300 W rating mean when the unit is installed in a PC?

It is the maximum continuous power the supply can deliver across all rails while maintaining 80 PLUS Gold efficiency and stable voltages.

How does the ATX form factor limit what I can connect?

The ATX design fits standard cases and provides the usual 24-pin, CPU, PCIe and peripheral connectors for typical desktop builds.
