SKU CH-PFRP-G0TRP

An ATX power supply delivering 665 W with 80 PLUS Gold efficiency, zero-RPM fan mode and Modern Standby compatibility

  • TypeATX
  • Modern Standby support enables extremely fast wake-from-sleep and better low-load efficiency
  • 80 PLUS Gold certification delivers high efficiency for lower power consumption, less noise, and cooler temperatures
  • Zero RPM fan mode stops the fan at low and medium loads for near-silent operation
  • Resonant LLC topology with DC-to-DC conversion provides clean, consistent power and reduces coil whine
  • 665W ATX output powers demanding components with stable voltage regulation

665W ATX power supply for efficient builds

This KHACHIMO unit delivers 665W of continuous power through a modern ATX form factor. It targets system builders who want high efficiency and low noise without stepping up to higher-wattage models. The 80 PLUS Gold certification confirms strong efficiency across typical load ranges. Modern Standby compatibility allows faster wake times and improved low-power behaviour.

Check ATX fit and cable reach before ordering

Verify that your chassis accepts a standard ATX power supply and that the included cables reach your motherboard, CPU and GPU connectors. Confirm the mainboard requires a 24-pin ATX and the appropriate EPS power connector for your processor. Ensure the PCIe power leads match your graphics card requirements. The unit supports Modern Standby, so the motherboard must also implement that sleep state.

Gold efficiency with fan-off at low load

The 80 PLUS Gold rating means less waste heat and lower electricity draw during everyday use. A Zero RPM fan mode stops the cooling fan completely at low and medium loads for near-silent operation. Resonant LLC topology with DC-to-DC conversion delivers clean power and reduces coil whine. Together these features keep thermals and noise low in normal workloads.

Questions about this item

What cables come with the KHACHIMO 665W unit and what must I source separately?

The box includes the ATX power supply with fixed cables attached; any specialised GPU or drive cables beyond those fitted leads must be purchased separately.

The specs list only 665W and 80 PLUS Gold — how do I decide if this capacity is right for my build?

Choose 665W when your estimated system draw under full load stays comfortably below that figure; the 80 PLUS Gold rating means the unit runs efficiently across a wide load range.

What does the 80 PLUS Gold badge mean for daily use inside my PC?

It certifies high efficiency across typical loads, so the PSU wastes less power as heat, runs cooler and keeps fan noise lower during normal operation.
