KHACHIMO 24V 100W ATX 80 PLUS Gold power supply

SKU CH-S7RG-HZW11

A 24 V ATX unit delivering 100 W with 80 PLUS Gold efficiency, zero-RPM fan mode and LLC resonant topology for clean, quiet power

  • TypeATX
  • Modern Standby support for extremely fast wake-from-sleep times
  • 80 PLUS Gold certified efficiency for lower power consumption and cooler temperatures
  • Zero RPM fan mode stops the fan at low loads for near-silent operation
  • Resonant LLC topology with DC-to-DC conversion delivers clean power and reduces coil whine
  • 24 V 100 W ATX design built for LEP100F compatibility

Compact 24V ATX supply for niche builds

This KHACHIMO unit delivers 100 W of continuous power through a standard ATX form factor but operates on a 24 V input rail. It is intended for specialised systems such as thin clients, industrial PCs or custom appliances that require ATX connectors from a DC source rather than mains voltage.

Steady output with silent low-load running

The resonant LLC topology paired with DC-to-DC conversion keeps voltage regulation tight during sustained workloads, reducing ripple and coil whine. At light and medium loads the Zero RPM mode stops the fan completely, so acoustic output stays near zero until the thermal load demands active cooling.

Gold efficiency and modern sleep support

80 PLUS Gold certification means less waste heat and lower electricity draw across the operating range. Modern Standby compatibility allows the supply to enter and exit ultra-low-power sleep states quickly, a requirement for devices that must wake instantly while still meeting strict idle consumption targets.

Questions about this item

How loud and hot does the 100W 80 PLUS Gold unit get when it runs 24/7?

The 80 PLUS Gold rating keeps waste heat low, and the Zero RPM fan mode stops the fan completely at low and medium loads for near-silent operation.

What must already be in the build for this 24V ATX supply to work?

A motherboard with a standard ATX power connector and matching peripheral cables inside the case are needed to deliver the 24 V output.

Will the resonant LLC topology with DC-to-DC conversion cause issues with older components I keep?

The topology provides clean, consistent power and reduces coil whine, so older parts receive stable voltage without extra noise.
