KHACHIMO

KHACHIMO 500W ATX 12V 42A 80+ Gold Power Supply

SKU CH-9EJJ-7X4N9

An ATX power supply delivering 500W with a 12V rail rated at 42A, 80 PLUS Gold efficiency, zero-RPM fan mode and LLC resonant topology for clean, quiet power

  • TypeATX
  • Faster wake-from-sleep with Modern Standby support
  • Lower power draw from 80 PLUS Gold efficiency
  • Silent running at low loads via Zero RPM fan mode
  • Clean, stable power from resonant LLC and DC-to-DC design
  • 500 W ATX output with 12 V 42 A capacity

Efficient ATX Power Delivery

This 500W ATX unit supplies a 12V rail rated at 42A and carries 80 PLUS Gold certification for high efficiency. It targets builders who want reliable output with lower energy waste and reduced heat in standard desktop chassis.

Quiet Cooling and Modern Standby Support

A Zero RPM fan mode stops the 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, while Modern Standby compatibility enables extremely fast wake-from-sleep times and better low-load efficiency.

Limits of the 500W ATX Standard

The fixed 500W capacity and single 12V rail at 42A restrict use with high-end multi-GPU configurations or extreme overclocking builds. Systems requiring significantly higher peak power or multiple auxiliary connectors will exceed what this design can safely provide.

Perguntas sobre este artigo

What does the 80 PLUS Gold rating on this 500W unit mean for efficiency?

80 PLUS Gold certification means the supply meets high efficiency targets at typical loads, reducing power draw, heat output and fan noise compared with lower-rated units.

What physical space and mounting does this ATX power supply require?

It follows the standard ATX form factor, so it fits any case with an ATX PSU bay and uses the usual four rear mounting screws.

How do I enable the Zero RPM fan mode on this PSU?

The fan stops automatically at low and medium loads; no user setting is required — just ensure the unit is not obstructed so the thermal sensor works correctly.
